Cancer and Dental Health: Managing Your Oral Care During Treatment
Cancer treatment can affect your mouth, including saliva, teeth and oral tissues. Arrange a dental evaluation before treatment when possible, and share your oncology team’s contact information so the timing and precautions can be coordinated.
At CJ Henley, DMD, we serve as an essential part of your oncology team, providing specialized care for patients undergoing chemotherapy, radiation, and surgery.
Why should I see a dentist before cancer treatment?
Your mouth is a high-risk area for infection when your immune system is weakened by chemotherapy. Before treatment begins, a pre-treatment dental evaluation is critical to:
Identify and eliminate existing infections that could become life-threatening during immunosuppression.
Stabilize compromised teeth to prevent the need for emergency surgery during active treatment.
Establish a baseline for your oral health to manage changes as they occur.
If you are beginning treatment in Jacksonville, we coordinate directly with oncology teams—including our ongoing collaboration through the Baptist MD Anderson Head and Neck Tumor Board—to coordinate dental care with your medical schedule.
What mouth problems can cancer treatment cause?
Radiation and chemotherapy affect the rapidly dividing cells in the mouth, leading to several common conditions:
Oral Mucositis: Painful mouth sores and inflammation that can make eating and speaking difficult.
Xerostomia (Extreme Dry Mouth): Radiation can permanently damage salivary glands, leading to thick, sticky saliva and a significantly increased risk of rapid tooth decay.
Increased Infection Risk: Fungal (thrush) or bacterial infections are more common when the immune system is suppressed.
Jaw Pain and Stiffness: Particularly for those receiving radiation to the head and neck.
Specialized Care for Complex Medically Involved Patients
For patients managing Complex & Medically Involved Care, the stakes are higher. Our practice specializes in the specific protocols required for:
Osteoradionecrosis (ORN) Prevention: For patients who have received high-dose radiation to the jaw, certain dental procedures (like extractions) carry high risks. We utilize conservative management and specialized surgical protocols to maintain jaw bone health.
Post-Radiation Restorations: Saliva is the mouth's natural defense against decay. When saliva flow is compromised, we use specialized high-fluoride protocols and biocompatible materials designed for longevity in a high-risk environment.
Your Path Forward
Whether you have just received a diagnosis or are currently in the recovery phase, we provide an unhurried, two-hour comprehensive evaluation to understand your medical history and design a protective care plan.
