Inhaling and exhaling through your nose rather than your mouth can benefit dental health. This is because inhaling through the nose allows odors to pass into the nasal cavity so they don’t get absorbed by the rest of the body. On the other hand, exhaling through your mouth means that any saliva that has accumulated and left after a meal will be swallowed back down with any other leftover particles in the saliva. Breathing through your nose can also help reduce congestion, especially helpful for people who have issues with their sinuses.

How breathing through your nose is linked to dental health.

Certain bacteria thrive in the mouth, and when they grow in excess, they can cause dental diseases like gum disease and cavities. When you breathe through your nose rather than your mouth, you prevent these bacteria from entering your nasal passages by passing them through your nasal cavity, where they can’t grow. If you breathe through your nose, you will have less opportunity to ingest bacteria. This means you are less likely to get ear infections, tooth decay, gum disease, and bad breath. When you breathe through your nose, you can also take advantage of lower concentrations of pollutants in the air to make your nose less irritated by them. Intermittent sniffling while sleeping is one example of how this process can help you sleep better.

Why Breathing Through Your Nose is Good for Dental Health

When one is inclined to wear, bacteria find it much easier to set up camp in the pores of their teeth, where they can cause cavities. Additionally, the air that comes into contact with your teeth when you breathe through your mouth can cause staining and bad breath. If you breathe through your nose, you will avoid these issues altogether. While breathing through your mouth, any bacteria that make it into the mouth get swallowed with the saliva. If any residue is left on your teeth after eating, it will be considerably diluted.

Benefits of Breathing Through Your Nose

Lessens congestion – When you breathe through your nose, you will get a minor sinus infection. Air passage through the nasal cavity is likely to remove any dead cells and other debris blocking the sinuses.
Helps to prevent ear infections – Since you will be less likely to inhale bacteria into your mouth, you are also less likely to get an ear infection.
Improves nasal health – If you breathe through your nose, you will be inhaling less pollen, dust, harmful chemicals in the air, and other potentially damaging particles. This can help to prevent any nasal blockage and improve your nasal health. Better smelling breath- By bypassing the mouth, you are more likely to be inhaling higher concentrations of odor molecules. The better-smelling breath resulting from this is beneficial for those with halitosis.


Breathing through your nose rather than your mouth can be beneficial to dental health because it reduces the number of bacteria that can cause dental diseases, bad breath, and bacterial infections in the mouth. Furthermore, people who breathe through their noses are less likely to develop gum diseases such as periodontal diseases and gum disease.
