GC Tooth Mousse Review and Advice for Use

It is time for my second review. This time it is the GC Tooth Mousse. I have been using this product on my patients and myself for several years and I am going to tell you how I choose the patients whose teeth will get application of Tooth Mousse and why many patients also get advice to use Tooth Mousse at home.

There will be instructions on how to use the Tooth Mousse at home and in surgery.

What Is Tooth Mousse?

Gc Tooth Mousse review by Dental Revelations

Mousse? Not really. The name is slightly misleading as it is more like a gel. But I guess strawberry flavoured mousse brings positive associations in people’s minds. Almost like a delicious dessert. It does taste pleasant though. There are 5 different flavours: the featured strawberry, vanilla, melon, mint and tutti-frutti.

Let’s see first what the manufacturer’s selling speech is:

When Tooth Mousse is applied to tooth surfaces, the CPP-ACP molecule binds to biofilm, plaque, bacteria, hydroxyapatite and surrounding soft tissue.

-Delivers Recaldent™ Casein Phosphopeptide – Amorphous Calcium Phosphate
-Inhibits enamel demineralisation and induces remineralisation
-Reduces hypersensitivity by obturating open dentinal tubules
-Prevents initial caries forming thanks to the anti-cariogenic properties
-Reverses white spot lesions
-The delicious flavours stimulate saliva flow for an enhanced effectiveness of CPP-ACP


Many difficult to understand words I think. And this letter combination CPP-ACP, what the heck is that? If you are a common consumer, you probably are not 100% sure what you just read. I will try to tell the same in more simplified way.

What Is the Secret in Tooth Mousse?

It is the milk. Well part of it.

It is known that milk is beneficial to dental health due to its calcium and other derivatives. Tooth Mousse contains plenty of calcium complex of CPP-ACP (see below where this abbreviation comes from), commercially named as Recaldent, which is the ideal delivery system for calcium and phosphate ions that are naturally available in milk.

Recaldent is derived from the milk protein, casein hence the protective effect to the teeth.

Research has shown that this activity is due to a part of the casein protein called Casein Phosphopeptide (or CPP), which carries calcium and phosphate ions in the form of Amorphous Calcium Phosphate (or ACP).


GC Tooth Mousse does not contain fluoride but there is a product called GC Tooth Mousse Plus that contains fluoride (900ppm).

Who Benefits of Using Tooth Mousse?

On top of my list are definitely the patients with signs of dental erosion. But these people fall into two different categories – to the ones whose dental erosion is active and progressing and to the ones whose dental erosion has stopped progressing and no reason from diet or health, that would cause erosion, can be found.

The former group will always (with three exception, will tell you about it later) get an application of Tooth Mousse in my surgery. People who belong to this group are often vegetarians, vegans and people suffering from gastric reflux – they are the ones who suffer from the dental erosion the most. And especially people who have gastric reflux and grind/clench their teeth at night – if they use night guard, then even more so as the saliva that protects the teeth is present in very small amounts in mouth at night and this small amount of saliva is not able to reach the top teeth that are covered by the night guard.

Dental Revelations Blog-2
Mouth guard. Read about them here.

The problem is that even though the saliva is not able to reach the top teeth, the stomach acid is because it travels on the surface of the tongue. The tongue rests often against the roof of the mouth and the stomach acid has access under the night guard. And stomach acid is very acidic – its pH is between 1,5-3,5.

To these patients I also advise to buy Tooth Mousse to be used at home. And once they have used it regularly I often see that the enamel has restored its shine again. Of course you cannot grow the lost enamel back by using this product but Tooth Mousse will make the remaining enamel stronger to the effects of acids.

The dental erosion is not the only reason for the application of the Tooth Mousse. I will apply Tooth Mousse to the patients

  • that suffer from dry mouth (xerostomia)
  • who have high risk of caries
  • who have hypersensitivity

Also I apply Tooth Mousse after scaling and root planing, after bleaching and after removal of orthodontic brackets to prevent sensitivity after treatment.

The Exceptions?

I do not apply the Tooth Mousse to people

  1. who are allergic to milk protein as the Recaldent is derived from the milk protein, casein.
  2. who are allergic to hydroxybenzoates.
  3. who are strict vegans as everything entering the mouth should be plant-based.

How to Apply Tooth Mousse at Home?

It is very easy to apply Tooth Mousse at home. If you are a night guard user, continue reading further to find out how to use it with night guard at night.

Follow these simple steps:

  1. Brush your teeth and clean in between the teeth thoroughly.
  2. Wash your hands and apply pea size amount to the back of your hand. Then apply another same sized amount next to the first one (see photo). Now you have one dosage for your upper teeth and one for your lower teeth. This is the minimum dosage.
  3. Use a clean finger or a cotton swab/bud (see the photo) so spread Tooth Mousse all over you teeth (see photo).
  4. Leave the Tooth Mousse undisturbed for at least 3 minutes (go and watch the telly to make the time pass quicker – it doesn’t matter if the Tooth Mousse stays undisturbed in your mouth for longer. The longer it stays, the better).
  5. Once 3 minutes has passed, move your tongue over your teeth to spread the mousse everywhere in your mouth, including the soft tissues. You can swish the mixture of saliva and Tooth Mousse around your mouth. Try to keep the liquid in your mouth for 2 minutes and then spit out the liquid. There is also an option not to spit out – just spread the mousse with your tongue all over you mouth and that’s it. Leave it there. If doubting – jump to
    Is It Necessary to Spit It Out?
  6. Do not eat, drink or rinse for 30 minutes.

Tooth Mousse with night guard (especially if you suffer from gastric reflux):

  1. Brush your teeth and clean between the teeth (or vise versa, it doesn’t make much difference which way around you do it).
  2. Clean the night guard by using manual toothbrush for it. Do not use toothpaste for the night guard.
  3. Apply small amounts of Tooth Mousse inside the night guard (see photo) and place it in your mouth.
  4. Sleep tight, don’t let the bed bugs bite.
  5. In the morning, brush the night guard with manual toothbrush and rinse with water. Brush your teeth as well.

How to Apply Tooth Mousse in the Surgery?

Demonstrative photo.

If there is lots of saliva in the surfaces of the teeth I dry the surfaces with a cotton roll. The enamel does not need to be absolutely dry so do not use pressurised air.

For the application I often use Monject syringe with a black dispensing tip (19 gauge) but it can be applied also with a cotton roll – just remember the aseptic technique. Pea size amount per arch is the minimum amount for the application.

Now after the applications there are two ways to do proceed. I pretty much always ask the patients to ignore the Tooth Mousse for couple of minutes and then to move the tongue over the teeth to spread the gel also to the soft tissues. And that’s all. Very simple to apply. But always remember to instruct the patient not to drink, eat or rinse for half an hour after the application.

Another option is to repeat the above but after the patient has spread the gel around the mouth you can advice her to wait for couple of minutes before spitting out all the extra saliva and Tooth Mousse. Advise patient not to eat, drink or rinse the mouth for half an hour.

Personally I stick to not spitting out.

Is It Necessary to Spit It Out? Oh, the Confusion!

Now personally I find it confusing that two different ways to do it is advised by the manufacturer. Why not stick to advising to leave the Tooth Mousse in mouth if there is no reason to spit it out?

In their leaflet where Tooth Mousse is introduced, they advice to leave the Tooth Mousse in mouth without spitting:

For at-home use: when your patients apply Tooth Mousse and MI Paste Plus immediately before going to bed, they should leave it on their teeth to slowly dissolve overnight.

But in their instructions for use (IFU) that is found inside the package the advise given is the opposite:

4. Expectorate thoroughly and if possible avoid rinsing. Any GC Tooth Mousse remaining on the surface can be left to gradually dissipate overnight. Do not eat or drink for 30 minutes following application.

To make it even more confusing, on their FAQs leaflet they leave it up to the consumer whether to spit out or not. This what the manufacturer answers to the customer’s question Do I need to wash it off?

This is a matter of preference. For the maximum benefit, leave it on the teeth as long as possible. The minimum recommended application time is three minutes. You can then rinse the mouth or simply wipe any remaining crème from the teeth.

And to the question Is it safe to swallow?

Yes. The main ingredient of GC Tooth Mousse® is derived from milk casein and, like milk and cheese, is edible. GC Tooth Mousse® should not be used by people with milk protein allergies or sensitivity to benzoate preservatives.

If it does not really matter whether to rinse or not to rinse but it would be beneficial to leave the Tooth Mousse in mouth as long as possible, I repeat – why not stick to advising Do not spit?

Would I Recommend This Product?

Hell, yeah.

I have noticed numerous times that sensitivity after scaling and root planing is almost non-existent every time I have applied Tooth Mousse after treatment.

Also the enamel restores its shine after patient suffering from dental erosion has used Tooth Mousse regularly. Of course I must say that one part of this process is the fact that many people change their lifestyle habits once they understand that the enamel does not grow back once it’s gone. There is natural defence in everyone’s mouth and that is saliva. As long as there is not too much for the saliva to handle in daily basis (e.g. sour drinks, snacking), it can keep the enamel healthy.

It is comforting to know that there is something that the patients suffering from the gastric reflux can use at night to protect their teeth from the stomach acid. Gastric reflux is a nasty thing to have and very often patients do not even know they are suffering from it but that is completely another story. I might write a short post about it soon.

  1. Hi,
    I’ve been suffering with unexplained teeth pain for years but it’s got worse over past month. I have extreme sensitivity and receding gums but my dentist can’t see anything wrong with my teeth. It’s got so bad I’ve developed a fear of eating so now have nutritional shakes but I’m losing so much weight. Will the Tooth Moose help my sensitivity and how long before I might see an improvement. Please help as I’m at my wits end.


    1. Hello, hypersensitivity can be due to several reasons. I suggest to read the posts below to see if there’s something you do in your daily life that could be causing sensitive teeth (habits that could cause dental erosion which is very common reason for sensitivity). The nutritional shakes actually might make matters worse as they can be acidic plus they require no chewing which would be important to get the protective saliva to flow.

  2. Thank you! Currently reading this with my strawberry tooth mouse in my mouth. They now sell it at Woolworths (Strawberry and Mint).


  3. Hi, I just went to a dentist. I hav overbite teeth and my teeth in the lower jaw have become sensitive.My dentist recommended to keep braces .I am not understanding what happens with over bite
    .Please help me I m just 17 .


    1. Hello Dilip, Thank you for your question. I assume your dentist referred you to an orthodontist (specialist dentist who corrects bites, occlusion and straightness of the teeth)? Treatment such as braces should be performed by orthidontist. An overbite normally will cause problems later in life if it is not corrected. This of course depends on the severity of the overbite. An overbite is easier to correct with children and teens. It is more complicated as an adult and may involve surgery (performed by Oral and Maxillofacial Surgeon). I found very informative page about overbite for you to read. It explains also what happens with overbite if not corrected. It might be a good idea for you to book a consultation appointment for orthodontist to find out exactly what is needed to be done and what happens if you don’t. Braces might sound like something undesireable but they are very common and time goes by very quickly (well at least with us adults). Most important thing with the braces is to look after your teeth even better than before and to make sure you don’t snack often or drink other than water between the meals. Here’s the link.
      I hope this was helpful. If any questions, please do not hesitate to ask. All the best, Dental Revelations Blog


  4. Hi
    Thank you for this informative review.
    My question is that some of my teeth have lost enamel and I am experiencing super sensitivity at times. I had consulted two Dentists one recommended GC tooth Mousse and another one said that it’s of no use as you can never grow enamel again.
    What should I do? Also they have changed my toothpaste to VANTEJ and I am using it for around 9 months now but I don’t see any major results. Even my teeth looks more yellowish after this toothpaste ”Vantej” and I never feel fresh mouth after using it unlike Colgate. At least my teeth were white when I was using Colgate. Also I always use Sensodyne tooth brush and change it every month.
    Please suggest what should I do?


    1. Dear Nikita, thank you for your question. I’m not sure what the second dentist is on about when he says that there’s no point using GC Tooth Mousse.
      What has been exposed when the enamel is lost completely is dentin. There are tiny channels (tubules) from the surface of the dentin to the nerve inside the tooth. These tubules should have “mineral cap” on the surface of dentin. This mineral cap will stop sensitivity. It may dissolve if you have too acidic diet (flavoured, carbonated drinks, flavoured tea, fruits, vegetarian diet etc) or if you brush your teeth after meals. Also if you are suffering from gastric reflux and it’s not medicated, the stomach acid can remove mineral from your tooth. There are other reasons too.
      If we want to build up the mineral cap again, we need fluoride and calcium (plus changes in diet). Fluoride you get from the toothpaste and calcium you can get from e.g. the GC Tooth Mousse. I emphasize that you need to use both or at least fluoride toothpaste. You can use the GC Tooth Mousse many times a day. Fluoride toothpaste is recommended to use twice a day (1450ppm of Fluoride). The Vantej seems to be fluoride-free toothpaste so it’s not a good idea in many ways to use only this product. I would advice you to get back on using regular fluoride toothpaste (e.g. Colgate but stay away from the whitening ones). And to use GC Tooth Mousse along side. It might be that you need a professional teeth cleaning to remove superficial stains. The enamel won’t grow back but the surface of the tooth (dentin and enamel) can be made stronger by this method mentioned above. It might be good idea to read my posts about dental erosion (esp. Dental Erosion in Bullet Points) so you will know if there is something in your habits or lifestyle that is causing the mineral loss.
      It’s also good to know that severe (the enamel is lost completely and dentin is worn) enamel loss that affects the occlusion or the aesthetics of the teeth, can be fixed by restorations. But for that I would recommend seeing a Prosthodontist (check they have their degrees too, so that you will not choose a regular dentist who specializes in rehabilitation of the occlusion).
      Hope this was helpful. Do no hesitate to ask more.

  5. Hi! My dentist said my teeth are at a risk of developing cavities so he recommended to use this in place of a toothpaste. Should i still follow it? Because everywhere i read it says to leave it on the teeth for a while


    1. Hello! I would recommend Tooth Mousse Plus if you are going to stop using your toothpaste. The fluoride is vital in prevention of cavities especially if you are more prone to cavities. There is fluoride in the Tooth Mousse Plus although only 900ppm when normal toothpaste for adults has 1450ppm of fluoride. The Tooth Mousse does not contain fluoride and it would not be sufficient for somebody who is high-risk for developing decay. It should be used along side with fluoride toothpaste. Hope this was helpful!


  6. Hi
    My first son at the age of one, his parts of the teeth started falling off. And top front 4 teeth is almost gone. And now I noticed the same for my second baby. His top two tooth looks very weak and colour has changed as well. I would like to try the mousse. Is it effective to try for a one year old toddler who is still breastfeeding ?


    1. Hello, the best thing to do is to let a dental professional find out tje reason for the enamel loss. Before seeing a dentist/specialist dentist, you can write down your daily feeding routine. How many times a day does your baby feed? Do you give a juice/sugar water in a bottle bottle? Do you let your baby to sip these drinks many times a day? The baby should only drink milk (preferably only breast milk) and water (not carbonated or flavoured). They shoud never fall asleep with a sugary drink in a bottle. The feeding times (solid food) should be regular – breakfast, lunch, snack, dinner, evening snack. The baby should not be given sweet treats (like lollipops, honey). If you want to, I can analyse your daily feeding routines. Just write down everything that goes into baby’s mouth in 3-4 days (food, drinks, sweet treats etc) and time of the day plus for how long does the eating/drinking last. You can send it to dentalrevelations@gmail.com.
      I would not use tooth mousse for a baby. The professional evaluation is the most important thing to do.


  7. I have braces and a speck of plague on two of my bottom teeth and it irritates me so much. Will this help…. It’s really not visible unless you really look but it’s enough for me to worry


    1. Thanks for your question. It is very common to have plague and tartar on lower front teeth even without braces. When you have braces it builds up easier. It would be advisable to see hygienist every 4 months while you have braces – she will remove the build up and guide you through the oral hygiene methods suitable for your teeth. The GC Tooth Mousse will not help I’m afraid. All the best!


  8. Plz tell for how long GC tooth mousse be used for sensitivity problem. Should it b discontinue d after a month or so. Plz tell should it b used once or twice daily


    1. Hello! Thank you for your question. You can use Tooth Mousse as long as needed. It can be used as many times as you desire but the most important time to use it is at night just before going to bed. The best thing would be if Tooth Mousse could stay in mouth as long as possible.


  9. Regarding step 5 of the mouthguard section:
    ”In the morning, brush the night guard with manual toothbrush and rinse with water. Brush your teeth as well.”
    If I have GERD and also dry mouth at night, is it safe to brush my teeth upon getting up in the morning?
    Thank you!


    1. Hello! Thanks for trusting me with this matter. Couple questions comes to my mind. First, do you wake up at night because of dry mouth? If not, then it is normal. If yes, then it mainly affects the quality of life (disturbed sleep). We all get dry mouth at night to some extent but it should not wake you up. Second question, is your GERD medicated and therefore symptomless? If no, you should see a doctor to get prescription medicine to treat it. If the medication does not help, it might be wrong type of medication or wrong dosage. If the answer is yes, then you do not need to worry about your teeth. It is important to get the GERD symptomless (it sometimes requires both regular medication and lifestyle changes).

      It is safe to brush your teeth in the morning (first thing), but if you feel that GERD is active, you could just rinse with tap water, then brush you teeth. But first spread the fluoride toothpaste evenly to your teeth.

      Hope this was helpful. All the best!


      1. Thank you for your lengthy answer. My doctor prescribes PPIs but it seems that they are not meant to be taken long-term. And even if symptomless I might still have silent reflux? I took them for 5 years and stopped 2 years ago. The GERD symptoms are not serious enough for me, and have almost never disturbed me at night, so I try to manage it without prescriptions. My only real worry about it would be my teeth and gums… They are not in the best of shape but my dentist offers little clue as to what might harm them. Only grinding is brought up once in a while as a possibility, but I never notice it myself. She says the teeth are still alright, and gums are not worrisome despite receding, which might be caused by grinding.

        Dry mouth started after taking cipro 4 years ago (as well as many other neurological side effects and my trust in doctor’s opinion on drugs). I would often wake up completely parched but now it’s not as serious. I can’t say for sure whether I wake up specifically because of it but I developed a habit of keeping a full glass of water by my bed every night so I can take sips to moisturize once in a while. I heard from other cipro sufferers that they developed dry mouth or that their teeth and gums have been affected (although that part is mostly anecdotal).

        So all in all, I was just wondering whether rinsing with water after waking was enough to prevent harm from the brushing. I already avoid brushing after eating or having juice/coffee. Thanks again. I find your website to be very resourceful. Yes I do look for answers on the web (I feel I don’t have a choice) but I try to find only the best information from knowledgeable people.

      2. Yes, your dentist is correct that receding gums can be caused by grinding (or clenching). Especially if there is imbalance in bite. Check my post https://dentalrevelations.com/2016/07/12/eeny-meeny-miny-moe-which-type-of-tooth-wear/ to find out more. Grinding/clenching combined with GERD can cause rapid tooth wear (occlusal). Dry mouth would work as enhancer to tooth wear.

        Sometimes grinding/clenching is not causing discomfort. Sometimes if you catch yourself from grinding/clenching during the day, it might be sign of you doing it at night as well. Sore facial muscles is another sign. Frequent headaches or shoulder/neck stiffness is another.

        For the dry mouth at night. I often advice people to use olive oil the last thing in the evening before going to bed. To apply about 1 teaspoon of olive oil on top of you tongue and spread it all over the soft tissues in mouth. This might prevent you from waking up for the dry mouth. I believe there are also olive oil sprays that might be easier to use.

        I am happy to hear my website has been helpful to you. You are wise to try to separate the correct information from fake news.

      3. I am forever a skeptic…
        Thanks for the suggestion about olive oil! Biotene did nothing for me and I found out from an article you linked to that it has a pH of 6.1… I guess the slight acidity of vegetable oil does not harm enamel?

        I know I am shooting in many directions here, but this reminds me of a practice I have heard of, called oil pulling…
        I never researched or tried it but the practice advises to use one tablespoon on empty stomach and that the oil should be spit out after 20 minutes and not swallowed.
        Here do you suggest that I keep a whole teaspoon in my mouth when I go to bed?

      4. You can decide the amount of olive oil used. Normally no more than a tea spoon amount is needed. As I suggested, some people use spray bottles to spray the olive oil. Olive oil can be swallowed – like we swallow the olive oil in salad dressings.

        I did a research about oil pulling and I’m afraid there is not enough scientific evidence of it being beneficial to dental health. https://www.nature.com/articles/bdjteam201849
        But there doesn’t seem to harm either of doing that. It is advised to do it in the morning which probably won’t help the dry mouth at night.
