Oral complications and cancer treatment

Although oral hygiene may not seem like a priority when you are diagnosed with cancer, about a third of patients experience oral complications.
A dry mouth, cracked lips, ulcers and dental disease are at the top of the list.
According to Dirna Grobbelaar, Ivohealth oral hygiene advisor, chemotherapy, radiation and medication can disrupt the balance of bacteria in your mouth.
She said the treatment limits the body’s ability to fight infections and dries out the mouth.
“This can make you more susceptible to cavities, gum disease and infections,” said Grobbelaar.
“Maintaining an effective oral care routine is important for your overall health and well-being, even when you’re not feeling well.”

To help you take good care of your mouth during cancer treatment Grobbelaar shared some advice:
• Dry mouth
A dry mouth, medically known as xerostomia, is a common side effect of many medications and radiation.
Because saliva is the body’s way of naturally cleaning the mouth, plaque and bacteria build up more quickly.
This puts patients at a higher risk of bleeding gums, bad breath and dental decay.
Rehydrating your mouth is a priority.
Drinking water will give temporary relief while an oral lubricator or spray and gel will last longer.
Chewing sugar-free gum can stimulate saliva flow while some medications can help produce saliva.
• Mouth ulcers
Many cancer patients experience mouth ulcers which make eating, talking and cleaning the mouth uncomfortable.
Use available medication to create a barrier over the ulcer for immediate relief and promote faster healing.
Don’t be tempted to skip your oral care routine because your mouth is sore; keeping it clean can help prevent further infection.
• Cracked lips
Protect your lips with a lubricating barrier to prevent them from becoming dry and cracked.
Licking your lips will make it worse.
Rather regularly apply a moisturising balm and drink plenty of fluids to keep the mouth and skin hydrated.
• Dental problems
Gum disease, dental decay and cavities are all common dental problems during cancer treatment. These are best prevented with an effective daily oral care routine and professional support.
Visit your dentist for a thorough check-up before your treatment starts, to detect and treat any existing issues.
See the oral hygienist for a professional cleaning at the same time to remove plaque and tartar build-up.
During treatment, some patients may experience nausea and vomiting.
Vomiting demineralises teeth enamel and weakens the teeth.
Don’t brush your teeth immediately after vomiting simply rinse with water or an alcohol-free mouthwash with fluoride then wait an hour before brushing.
