Burning chest pain and bitter taste in mouth

The bitter taste may reflect acid reaching the throat or mouth, while the chest burning may arise in the esophagus. Dental erosion, dry mouth, medicines, and oral infection can affect taste, but they do not explain all chest pain.

If the pain is new, severe, pressure-like, or accompanied by breathlessness, sweating, faintness, nausea, or pain in the arm, jaw, or back, seek emergency medical care. For recurring milder symptoms, note meal timing and arrange medical assessment; a dentist can check enamel erosion and oral causes.

Call emergency services for persistent or severe chest pain, breathing difficulty, fainting, or associated jaw or arm pain. Seek dental care for tooth sensitivity, enamel wear, or a persistent unpleasant taste after urgent medical causes have been addressed.

Ask a medical clinician whether reflux, heart, lung, or medication causes need assessment. Ask the dentist whether the enamel shows acid erosion and how to protect it while the underlying cause is treated.
