I brushed thoroughly last night, so what is this unpleasant feeling in the morning? Did you know that the cause of bad breath might not just be your brushing habits? A small hole hidden inside a tooth that looks fine on the outside can affect the health of your entire body.

When you open your eyes in the morning, do you notice an unpleasantly stale mouth odor instead of a clean, fresh feeling? It can make you hesitate before a good morning kiss with someone you love, and leave you covering your mouth before important meetings. This persistent halitosis, aphthous ulcers, and xerostomia might not simply be a matter of oral hygiene.
