Chemotherapy and medications that suppress the immune system can affect the tissues in your mouth. These treatments often make the gums and lining of the mouth more sensitive, increasing the risk of sores, infections, and bleeding. Because the body's ability to fight germs is reduced, even minor dental issues can become serious if not managed carefully.
If possible, visit a registered dentist before starting chemotherapy or immunosuppressive therapy. Completing necessary dental work in advance helps prevent infections during your treatment when your immune system is at its weakest. Your dentist can also provide advice on managing side effects like dry mouth or a sore tongue, which are common during these therapies.
During treatment, maintain a very gentle but thorough cleaning routine. Use a soft-bristled toothbrush and mild toothpaste to avoid irritating sensitive tissues. If your mouth is too sore for brushing, your dentist may recommend a specific antimicrobial rinse. Staying hydrated and avoiding spicy or acidic foods can help reduce discomfort and protect your tooth enamel.
Regularly check your mouth for any white patches, ulcers, or unusual redness. If you experience dental pain or signs of infection, contact your oncology team and your dentist immediately. They will work together to ensure you receive safe dental care that does not interfere with your primary treatment. Protecting your oral health is a vital part of your recovery journey.
