Oral Care: for chemotherapy and radiotherapy patients
PDF 111 KB
Chemotherapy treatment can affect your mouth in different ways. You may experience mouth ulcers, mouth infections, loss of taste or a dry mouth.
During chemotherapy the lining of the mouth may become thin and ulcerated. You may find eating and swallowing more difficult.
Infections can occur in the mouth because of a weakened immune system. It’s important to maintain good oral hygiene during chemotherapy to help reduce infections.
Start good oral care habits at home before treatment begins. Your mouth should be as healthy as possible before chemotherapy starts.
Most dental treatment should be avoided during chemotherapy. Emergency treatment is possible if your immune system is strong enough.
Use a very soft toothbrush during chemotherapy. If you need to stop brushing, a chlorhexidine-based mouthwash will help keep your teeth clean
Radiotherapy can affect white blood cells, skin cells and the lining of your mouth. These effects are often temporary but can persist. Problems occurring after radiotherapy depend on where the radiation is applied, how often the treatment is given and how much radiation is used.
Saliva lubricates the mouth and assists speech, taste and chewing. Saliva washes teeth providing minerals for repair. Saliva also helps prevent bacteria, viruses and fungi from causing infections, tooth decay and gum disease.
Radiation applied in the area of the salivary glands (below and in front of the ears and under the chin) can affect the amount and quality of saliva. This can be a permanent side effect of radiotherapy.
Sometimes saliva becomes thick and ropey, making swallowing difficult. This usually improves after radiotherapy is completed.
Whether the mouth is dry or has thick saliva, you need to take special care to protect teeth from losing enamel. Sipping water or using gels and lubricants can help moisten your mouth.
Ulceration and inflammation of the lining of the mouth occurs in areas that are directly affected by radiation. Tissues become red, swollen and painful ulcers may develop. Wearing dentures may be uncomfortable
Ulcers usually heal after treatment has finished. Mouthwashes and gels may help to reduce your discomfort.
Radiation can affect your taste buds. You may experience loss of taste. Radiation treatment applied to the head and neck area can affect the number of taste buds remaining at the completion of treatment.
Using chlorhexidine mouthwash is recommended during oncology treatment. Mouthwash can change the surface of the tongue and alter taste. Taste often recovers once cancer treatment is complete.
This is a severe complication that can occur following radiotherapy and affects the bones ability to heal. Tooth extraction following radiotherapy can make the condition worse. For this reason, dental work should be completed before starting radiotherapy.
Patients about to start radiotherapy are required to have a dental check-up. This helps identify any teeth and areas of the mouth that might cause problems. Any teeth that are severely decayed or loose should be removed before radiotherapy starts.
Start good oral care habits at home before radiotherapy begins.
