Cancer treatment can have a significant impact on a patient's oral health. Chemotherapy, radiation therapy, and other cancer treatments can cause a range of side effects that affect the mouth and teeth, including dry mouth, soreness, infection, and changes in taste. Coping with these side effects requires careful management of oral health. Patients should maintain good oral hygiene, including brushing and flossing regularly, and using mouthwash as prescribed. They should also avoid certain foods and drinks that can irritate the mouth, such as spicy or acidic foods. In some cases, medication or other interventions may be necessary to manage specific side effects. By working closely with their healthcare team and taking proactive steps to care for their oral health, cancer patients can reduce the impact of treatment on their mouths and maintain overall well-being.
