Radiotherapy to the mouth can make you more likely to get tooth decay and you'll need more frequent check-ups at the dentist in the future. Your spit has special minerals in it to keep your teeth and gums healthy. So if you have a dry mouth, this can also make you more likely to have tooth decay. Fluoride treatment can help to protect your teeth against the effects of radiotherapy, and your doctor might refer you for special dental treatment before your radiotherapy starts.
Gently brushing your teeth with a soft toothbrush and fluoride toothpaste as many as five or six times a day will help. It's very important to tell your dentist that you have had radiotherapy before having any dental work in the future.
