Booklet - The Oral Health Care Before and After Radiotherapy

4. Keep the oral cavity moist Sip water often to keep your oral cavity moist. In addition, you should refrain from smoking and alcohol so that your mouth will not be further irritated and dehydrated. 5. Care for the denture In order to avoid irritation to the oral mucosa, you should wear dentures for a shorter time. If the inflammation of the oral mucosa is only mild, you may wear the dentures briefly during eating and when participating in social activities. The dentures should always be kept clean to prevent oral mucosal infections as a result of wearing them. While not wearing, you should still clean the denture daily, and immerse it in water to prevent it from distortion.
