Chemotherapy and Your Teeth-What You Should Know

 Chemotherapy saves lives, but it can be tough on your mouth.  Cancer treatments target fast-growing cells.  Because the cells lining your mouth grow quickly, they often get caught in the crossfire. 

Understanding these effects can help you protect your smile during treatment.
How Chemotherapy Affects Your Mouth
  • Dry Mouth: Treatment slows down saliva production. Less saliva means bacteria thrive, increasing your risk for cavities.
  • Mouth Sores: Painful ulcers can develop on your gums and tongue, making eating and brushing difficult.
  • Bleeding Gums: Chemotherapy lowers your blood platelet count, which makes your gums bleed more easily.
  • Infections: A weakened immune system makes it harder for your body to fight off oral thrush or tooth infections.
Quick Tips to Protect Your Smile
  • See your dentist first: Resolve any tooth decay or gum issues before starting chemotherapy.
  • Brush gently: Use an extra-soft toothbrush and fluoride toothpaste after every meal.
  • Stay hydrated: Sip water throughout the day or use alcohol-free moisturizing rinses to combat dry mouth.
  • Skip the toothpick: Avoid sharp dental tools or flossing too aggressively if your platelets are low.
Your dental health is a vital part of your healing journey. Always keep both your oncologist and your dentist informed about any changes or pain in your mouth.
