If you have a decaying tooth in your mouth does it make your breath smell?!
Question:
If you have a decaying tooth in your mouth does it make your breath smell?
Answers:
A decaying tooth is festering with the germs that causes tooth decay, gum disease, and bad breath.
It serves as a reservoir for those germs to hide in, from which it will repopulate your entire mouth WITHIN MINUTES after you finish brushing.
That is the reason why people with cavities find it difficult to keep their mouth clean. It is a vicious circle.
So yes, a rotting tooth can keep your breath constantly smelling bad. It needs to be treated promptly.
