Should You Use a Mouthwash?

Dental Revelations Blog-1

Yes and no.

If you are a patient and you ask this question from two dentists there is a BIG chance that you will get two answers. The other shows you the green light and the other the red.

There is no consensus amongst the dental professionals about the recommendations. Even the professors in dentistry argue about the recommendations publicly. They give statements to the press for and against the mouthwashes after a new study about the risks of the mouthwashes is released. Some negate all the study’s conclusions.

So no wonder it leaves patients confused if us professionals are too.

Well Should You?

Generally no.

If you have a good oral hygiene – brushing twice a day and cleaning between the teeth most nights – and you use a fluoride toothpaste there’s no reason to use a mouthwash.

But there are exceptions – naturally!

If you suffer

  • from a gum disease you might be advised to use a mouthwash containing chlorhexidine (CHX) during and after a periodontal treatment. It is a very effective ingredient that kills bacteria. But remember to use it only as advised by a dental professional
  • from an extreme dryness of the mouth through an illness (e.g. Sjögren’s syndrome) you might be advised to use fluoride mouthwash regularly to prevent decay

Remember that in both of these cases you should choose the alcohol-free version.

Dangers of Using a Mouthwash

Oral cancer

If you use a mouthwash that has alcohol (ethanol, but I’m going to use the word alcohol instead) levels of 25% or higher and you have been using it since your teenage years the studies state that you have higher chances for getting an oral cancer.

One leading brand (the one that rhymes with word blistering) can have alcohol levels as high as 26% and this high level is thought to be toxic for gingival tissues when used in abusive amounts. But – and it is a big but – why do they add alcohol to the mouthwashes when it is a known fact that for alcohol to be toxic for bacteria it must be used at 40%? This means that there is no help from alcohol levels as low as 26% but it can still be harmful to the gingival tissues.

Discolorations

If you use a mouthwash containing CHX for a longer period of time it will stain your teeth. Stains can be removed but it will cost you of course.

In my professional life I have noticed that for some unknown reason the leading blistering-rhyming mouthwash stains the teeth with some patients eventhough it doesn’t contain the CHX. Actually the looks of the stains is different to those that build up from the CHX. After a thorough interview of the patient no other explanation was found to the stains than the mouthwash the patient had been using. The staining stopped once the patients stopped using the mouthwash.

Dry mouth and bad breath (halitosis)

Alcohol in mouthwashes can dry the mouth and the dry mouth is prone to halitosis. People often seek help from the mouthwash for the halitosis but it can actually make the matters worse.

Lichen planus

If you have been diagnosed with lichen planus you should not use any mouthwashes unless advised by a professional. But even in this case you should not use mouthwashes with alcohol.

WELL SHOULD I?

Wouldn’t it be the wisest thing to do if you DIDN’T use a mouthwash whilst us professionals argue about the health risks of the mouthwashes? It’s your health that is gravely at risk if the alcohol in mouthwashes is proven to be harmful.

I have seen patients who are going through the cancer treatments for oral cancer and I have seen the 50% of them who survived the cancer. I can tell you that it’s not a pretty sight. Not during the treatments or after surviving it.

Why would you play a Russian roulette over your health? I wouldn’t and therefore I am not using any mouthwashes.

If You Still Want to Use a Mouthwash

Always choose the alcohol-free fluoride mouthwash.

Remember

  • it can stain your teeth
  • it never replaces brushing or cleaning between the teeth
  • that in many countries the mouthwashes are considered as cosmetics by law. In some countries they are considered both cosmetics and drugs. But when considered as cosmetics they are not that highly regulated as drugs are. So what you could actually be rinsing in your mouth is a cocktail of chemicals that no-one knows (or cares) how they affect the health
  • that if you are also a heavy smoker it increases the risk of getting an oral cancer. If on top of that you are a high consumer of alcoholic drinks you are even at higher risk

Conclusion

I really don’t get it how we cannot decide if the mouthwashes containing alcohol should be recommended or not. It’s just ridiculous that even inside one dental practice opposite recommendations are given to the patients.

What all of us professionals agree is the fact that alcohol is an aldehyde and it is metabolised by the oral bacteria to acetaldehyde which is carcinogenic in humans. Carcinogens cause cancer! And yet we argue about the risks of using an alcohol containing mouthwash.

What are the reasons behind all this? Some have suggested that some of the dental professionals have financial commitments to the manufacturers of the mouthwashes. I must emphasise that this is a hearsay. But if you have read my previous post about the integrity amongst dental professional you understand that everything is possible.

  1. Good points you made in the Oral Cancer section, and has definitely left me with something to think about. That’s pretty interesting that alcohol mouthwash can increase your chances of oral cancer when it’s apparently supposed to improve oral health. Seems like using it is just a vicious cycle!

    1. Yes indeed. What bothers me is that we keep on recommending mouthwashes when we don’t know for sure that it is safe. Would you take a e.g vitamin supplement that is supposed to be good for your health, but the incredients in the tablet can actually kill you? Anyway. Once again I’m so grateful for the comment! Many thanks!
