How cancer can affect your mouth
Causes
- Oral complications can result from chemotherapy, immunotherapy, stem-cell transplantation, surgery, or radiation—especially radiation involving the head and neck.
Contributing Factors
- Existing decay or gum infection, dry mouth, low blood counts, poor nutrition, tobacco, and high radiation exposure increase complication risk.
Symptoms
- Possible effects include sores, dry mouth, infection, bleeding, taste change, jaw stiffness, severe decay, pain, or trouble eating and swallowing.
Practical guidance
What to do
At home
- Complete urgent dental treatment before cancer therapy when time permits, use meticulous gentle hygiene and fluoride, and report sores or infection promptly.
At the dentist
- The dental and oncology teams review cancer type, treatment field and timing, blood counts, medicines, oral disease, saliva, and planned procedures.
- Care may include moisture support, prescription fluoride, infection treatment, pain control, jaw exercises, nutrition support, and close coordination with oncology.
