Mask Mouth is the term used to describe the side effects of using face masks for a long time. Individuals with mask mouths who previously had healthy teeth and gums are now experiencing new dental issues. And it's not because of poor hygiene, but because of facemasks. 

We can't just throw away our masks and go back to our old ways, no matter how much we want to. Wearing a mask is obviously uncomfortable, and the oral problems it causes are inconvenient but breathing unfiltered air is still dangerous. Even if Covid 19 restrictions are relaxed, it remains unsafe to remove your mask in public places because the virus has not been completely eliminated.

Keep Covid 19 at bay while still protecting your mouth. Instead of rejecting face masks, we can try to learn everything we can about mask mouth in order to find relief and protection.

Causes of Mask Mouth

Hygiene and diet can also have an impact on mask mouth. However, using a face mask is still the main culprit. The following are the underlying causes of mask mouth caused by facemasks.

Dry Mouth:

Xerostomia, also known as dry mouth, is caused by inadequate saliva production.¹ Wearing a face mask for a long period of time causes us to breathe through our mouths rather than our noses. This action seems to have an effect on our saliva production. Saliva is crucial for maintaining oral balance. (Dry Mouth - Symptoms and Causes, 2018)
Although dry mouth is frequently overlooked, if left untreated, it can result in bad breath or halitosis, difficulty chewing and swallowing, and a weaker taste perception. In worst case scenarios, it can cause plaque build up that can then lead to teeth loss.

Bacteria In The Mouth

Keeping your mouth hydrated is essential for removing food particles and harmful bacteria. Unfortunately, wearing a mask makes it difficult to produce saliva.² (Can Wearing a Face Mask Cause Dry Mouth?, 2021)
Besides that, wearing a facemask makes it more challenging to drink water. Bad bacteria have a better chance of multiplying in a dry mouth. This leads to imbalances.

Restricted Breathing

Because the face mask limits your breathing area, it forces you to inhale the carbon dioxide you just exhaled. While inhaling small amounts of carbon dioxide is not harmful, this might increase the acid buildup within your body, putting you at a much higher risk of developing dental cavities and other health issues.³ (Taylor et al., 2021)

Undesirable Effects of Mask Mouth

Mask mouth side effects vary from person to person, but the disorder most commonly develops into the following.

Additionally, your mask may prevent you from drinking liquids at times. Not drinking enough water can cause stinky breath. Dehydration makes it challenging to wash away harmful bacteria and food residue.⁵ Because of the dryness, they can multiply and end up causing your breath to smell. (COVID-19 Pandemic: Effect of Different Face Masks on Self-Perceived Dry Mouth and Halitosis, 2021)

Tooth Decay        

Wearing masks for an extended period changes the pH or acidity level inside the oral cavity and reduces saliva production.⁴ Without moisture, good bacteria struggle to neutralize acids in the mouth and die. Acidity in the mouth causes tooth enamel to become brittle. As the enamel erodes, cavities and underlying tooth structure become visible. (Aubry, 2021)

Cavities form when there is an excess of acid and bacteria in the mouth. They are damaged areas of the tooth's surface that cause cracks, openings, or holes.

Halitosis or Bad Breath

Why does it appear that despite your best efforts to brush your teeth thoroughly, those unpleasant odors persist? The mask that is protecting you from certain viruses is affecting your breath. Face masks collect saliva as well as moisture from your breathing. They accumulate in the fibers of the mask and remain there for a set period of time.

Gum Diseases

When you don't produce enough saliva, your mouth becomes a breeding ground for bacteria and germs. If bacteria on your teeth are not properly removed, they can harden and form a film known as tartar. Tartar affects not only the teeth but also the gums. 

Gingivitis is a chronic condition in which your gums become red and inflamed.⁶ Gum pockets are formed when calcium deposits or tartar begin to accumulate on your gums causing openings and laceration. This causes your teeth to separate from the supporting bone. (How Masks Affect Your Oral Health, 2022)

What To Do If You Have Mask Mouth?

The main cause of "mask mouth," which can seriously affect your oral health care, is having to wear masks in public. Maintain your oral health while protecting yourself from Covid 19. Here are some actions you can take.

1. Maintain regular dental cleaning appointments to dissolve plaque on your teeth and prevent gum disease and tooth decay. 
2. Replace your mask after each use to prevent bacteria growth. To avoid cross contamination, used masks should be properly thrown away.
3. Drink a lot of fluids. Check to see if you're drinking enough water while wearing your facemask.
4. Before wearing a face mask, brush your teeth for at least two minutes. Scrape your tongue to prevent toxins and bacteria from reproducing on the surface of your mouth.
