A bad taste in the mouth all the time is often linked to bacteria collecting around the teeth, gums, or tongue. Dry mouth, gum irritation, sinus drainage, certain medications, and dental infections can also change the way the mouth tastes. If the symptom persists even with brushing and mouthwash, it may indicate that something deeper is affecting your oral health.
Many patients ask, “Why do I have a bad taste in my mouth when I brush regularly?” In many cases, bacteria remain trapped below the gumline or on the tongue, especially when saliva flow is low.
