Persistent dryness can affect comfort and increase the risk of decay.
Notice a persistent change
Dry mouth can be associated with dehydration, medicines, mouth breathing, anxiety and several health conditions. It can make speaking or eating uncomfortable and increases the risk of tooth decay. The symptom alone does not establish a cause, so a persistent change deserves discussion with a healthcare professional.
Mention medicines and other symptoms
Tell the dentist or doctor when dryness began and which medicines you take. Do not stop a prescribed medicine without medical advice. Dryness that persists for several weeks, affects eating or talking, or occurs with pain, redness, swelling or white patches needs assessment.
Support comfort while seeking advice
Regular sips of water and sugar-free chewing gum may help with comfort. Continue brushing and discuss a suitable oral care routine with the dentist. Mention other changes such as dry eyes or increased urination to your doctor, because the cause may need assessment beyond dental care.
