Bad Taste in Mouth (Dental Causes)
A persistent unpleasant or metallic taste often has a specific dental cause that assessment can identify.
Overview
A constant bad taste is a common symptom with many possible dental explanations — from an infected tooth, to gum disease, to food consistently trapping near a failing restoration, to dry mouth.
Because the taste buds respond to both volatile compounds from bacteria and chemicals released during inflammation, the presence of a persistent metallic or sour taste is often the earliest sign of a problem worth investigating.
A focused dental examination, supported by imaging where needed, usually identifies the cause in a single visit.
