Oral Health During Cancer Therapy
Certain cancer treatments can have side effects that may compromise the health of your gums. Understanding how to reduce impact on your gums is the first step to maintaining periodontal health during cancer therapy.
Pre-Treatment Evaluation and Oral Hygiene Routine
It is important to visit your periodontist for a comprehensive periodontal evaluation before undergoing any type of cancer treatment. Identifying and correcting potential problems in your mouth may prevent them from intensifying or interfering with chemotherapy or radiation. In addition to pretreatment care, your periodontist will likely recommend a daily oral hygiene routine to provide comfort, reduce the risk of infection, and minimize the effects of the complications caused by the cancer treatment.
Common side effects of cancer treatments (including chemotherapy, radiation to the head and neck, and bone marrow transplantation) can have a negative impact on your oral health. Radiation and chemotherapy kill cancer cells, but they can also hurt normal cells. Side effects vary for every person, but common oral complications include inflamed gums and mouth ulcers, dry mouth, erosion of tooth enamel, loss of taste, jaw stiffness, and delayed healing.
Although pretreatment and daily oral hygiene can go a long way toward keeping your mouth healthy and comfortable during cancer treatment, it may be difficult to keep side effects at bay. Chemotherapy and radiation can decrease your salivary secretion, causing excessive dryness in the mouth and increasing your susceptibility to infection. Therefore, it is important to keep your mouth moist by sipping cool water, melting ice chips in your mouth, chewing sugarless gum, applying lip balm to your lips, and using a humidifier in your bedroom to reduce oral dryness at night.
Protecting the enamel (outer surface) of your teeth is important if you’re experiencing dry mouth of vomiting.
Dr. Hong may prescribe fluoride trays, which will prevent the tooth enamel from wearing away due to vomiting or increased oral bacteria from dry mouth. You may also want to consider asking your oncologist to prescribe anti-nausea medication during your cancer therapy to treat nausea and vomiting.
