3. A bad smell or taste in your mouth
Foul-smelling breath could be a consequence of that sliced onion you had on your lunch salad. Or it could mean you’re not looking after your teeth and gums properly, and there’s a build-up of bacteria. Sometimes bad breath signals other health problems like gum disease, sinusitis, throat or lung infections, tooth decay, or an abscess. A bad taste in the mouth can also be a sign of an oral infection.
You may not realize your mouth smells rank. So if your spouse or partner comments on your bad breath, consider it a courtesy—and call your dentist’s office.
