I get this question on the daily, and my answer is usually the same. Generally speaking, most people with good oral hygiene habits do not require a daily mouthwash.
Our mouths contain many microbes and microorganisms that are beneficial to our oral environment. Using a daily mouthwash could be more detrimental to your oral health. We have a natural biofilm in our mouths (along with our saliva) that is an important protective source for our gums and teeth and using mouthwash can remove this protective biofilm layer.
That is not to say mouthwashes do not have a place… let’s look into this further.
There are different types of mouthwashes with different properties for different purposes.
- Antimicrobial/antibacterial – designed to kill, or render active types of microbes such as fungi, bacteria, parasites, and viruses.
- Antiseptic – designed to reduce the risk of infection by working against types of microbes. These usually contain chlorhexidine – an antiseptic agent used to combat plaque and gingivitis, and therefore often recommended for people fighting against gum disease.
- Fluoride – if decay rates are high, or enamel is weak, extra fluoride can help strengthen teeth.
If your dentist or hygienist has prescribed or recommended the use of a mouthwash, then there will be a reason for it (and it won’t be for ‘fresh breath!’). It could be to help treat gingivitis or gum disease, prevent tooth decay, post-surgery, remineralize the oral cavity, and so on.
Some types of mouthwashes can cause side effects such as staining, dryness in the mouth and a sensation of burning which is why prescribed mouthwashes are usually only recommended for a short period of time to contend with the issue or condition until it has resolved.
Most people that have good oral hygiene habits that include daily brushing and flossing, do not require a mouthwash. Brushing and interproximal cleaning are the two most important and effective ways to prevent tooth decay and gum disease.
For those that are determined to use a product to ‘freshen breath’ I typically suggest chewing sugar free gum instead.
Another alternative is a saltwater rinse. An oldie but a goodie. Salt water promotes healthy gums by effectively reducing plaque, therefore helping to prevent oral diseases. It is also known to help neutralize the acidity in our mouths thus preventing decay.
Salt water has long been known for its natural healing properties; however, it is important to note that excessive use can also be detrimental. ½ teaspoon of salt in warm water, 3-4x a week is sufficient.
I have noticed however, that people who love using a mouthwash tend to compromise their daily brushing and flossing efforts in lieu of using a mouthwash. Mouthwash can not remove the sticky plaque on the tooth surface; only brushing and interproximal cleaning can do this.
In a nutshell, unless you have been advised to use one, you’re better off saving your time and money as mouthwashes do not provide any real long-term benefit to your oral health.
