Can snoring cause bad breath?
If you've ever woken up with worse morning breath than usual, it may be because you snored last night. When you're snoring, you're breathing with your mouth open, causing dry mouth. When your mouth is dry, there isn't that protective layer of saliva to moisten the tissues in your mouth. Dry mouth can lead to bad breath, more bacteria buildup, infections and sores, and tooth decay.
Saliva is necessary to a healthy mouth because it washes away food debris and bacteria from the tongue, gums, and cheeks. When food debris and bacteria are not removed, they decompose and leave an odor behind (bad breath). Lack of saliva also allows harmful bacteria and other organisms in the mouth to grow too quickly, which can result in mouth infections and sores. When saliva can't protect and cleanse your mouth, it increases your tooth decay and gum disease risk.
If you can correct the reasons for your snoring, that may reduce your bad breath and other snoring effects. There are various treatments available. Those seeking treatment for snoring should consult their dentist or physician.
