Approximately every 3 minutes, someone in the United States is diagnosed with cancer. Oral complications resulting from anticancer therapies like chemotherapy and radiation can significantly affect morbidity, the patients’ tolerance, and their overall quality of life. Is your office prepared to handle the unique oral care needs of these patients?
In 1989, The National Institutes of Health had a Consensus Development Conference entitled “The Oral Complications of Cancer Therapies: Diagnosis, Treatment and Prevention.” The number one recommendation of the conference was that every cancer patient should receive a pretreatment dental oral evaluation, and any potential sources of infection be eliminated before initiating cancer treatment.
Sadly, more than 25 years later, this recommendation largely is not followed.
As a dental professional, you have been schooled in the concept of prevention from the first day of your professional training. When dental professionals are an integral part of the cancer management team, the treatment-induced oral side effects of cancer therapies can be greatly diminished or even prevented altogether.
To effectively treat medically compromised patients, you must first understand what these oral complications include and then how to manage and treat them.
Symptoms to Watch
In healthy individuals, the most rapidly dividing cells are the lining cells of the oral cavity and the upper esophagus. However, for patients receiving chemotherapy or radiation, these normally rapidly dividing cells of the mouth do not replicate. As they are sloughed off via regular eating, brushing, and other oral activity, the tissue becomes thinner. As the tissue thins, it may also ulcerate. These ulcerations (mucositis) are the first and most common side effect, occurring as soon as 8 to 10 days following the beginning of treatment. They can affect a patients’ ability to chew, swallow, and even speak.
Oral infections are also very common in cancer patients when the ability to fight infection is lost as the white blood cell count drops. Fungal infections are by far the most common, characterized by redness of the tissue, a burning sensation, and a white coating on the tongue.
Another common complication from patients undergoing radiation to the head and neck area in particular is xerostomia (salivary gland dysfunction), resulting from reduced or absent saliva flow. It can leave patients with a sore throat, difficulty eating and speaking, hoarseness, cuts around their mouth or lips, and a burning sensation in their mouth or throat. Cancer patients experiencing xerostomia are at a higher risk for infection and may require a saliva substitute or stimulant.
The good news is that if you develop a proper oral hygiene program with your patients, it’s possible to reduce the number of microorganisms such as bacteria, fungi, and viruses in the mouth and reduce the painful inflammation associated with treatment-related side effects.
It is standard practice that all patients who will be undergoing cancer therapy receive a comprehensive dental evaluation before beginning treatment. This evaluation should include a thorough history, including medication use; a full cleaning and examination to detect any potential sources of infection; the restoration of any tooth that might become infected; the extraction of any tooth that might lead to an infection; and the removal of any sharp edges on dentures, partials, and teeth.
Another important aspect of the process is patient education. During these visits, make sure the patients are aware that they should:
- Clean their mouth every 4 hours and before they go to bed. If they have a lot of mouth sores, they may wish to do this more frequently.
- Brush with a very soft pediatric toothbrush and replace it often.
- Use a gentle, fluoride toothpaste.
- Rinse as often as possible with a soothing mouth rinse like the Natural Dentist Healthy Gums Mouth Rinse that doesn’t contain alcohol, harsh chemicals, preservatives, or dyes. The Natural Dentist Healthy Gums Mouth Rinse is the only product on the market with a therapeutic amount of aloe vera, proven to soothe painful mouth irritations.
- Avoid alcohol and tobacco products.
- Avoid crunchy and spicy foods, as well as citrusy drinks like orange juice.
- Avoid hot food or beverages that can potentially burn their mouth.
- Examine their mouth every morning and night for changes.
Let your patients know that they should schedule frequent appointments during their cancer treatment (often weekly) to prevent infections and enable you to troubleshoot areas before major symptoms develop.
Caring for patients undergoing cancer therapies requires confidence, knowledge, and compassion. By playing an active role in their therapy, you can help decrease the cost of their care and increase their quality of life.
