Why Does Drinking Tea Cause Bad Breath?

Bad breath after drinking tea may indicate an underlying oral disease in the patient, such as periodontitis, pulpitis, or gingivitis. However, inadequate oral hygiene cannot be ruled out as a contributing factor. It is recommended that the patient first consult a dentist for a thorough oral examination. In daily life, maintaining good oral hygiene is essential: patients should brush their teeth and rinse their mouth promptly after each meal. Additionally, consuming foods rich in dietary fiber can promote gastrointestinal motility and help alleviate halitosis.
