Introduction

This leaflet is designed to give you information about some of the ways in which chemotherapy or radiotherapy to the head and neck can affect your mouth. We hope it will answer some of the questions that you or those who care for you may have at this time.

Radiotherapy and chemotherapy are treatments that are used to treat cancers, including those of the head and neck.

How should I prepare for my cancer treatment?

Radiotherapy and chemotherapy to the head and neck can have side effects in the mouth. Your oral health needs to be as good as possible before the start of treatment to avoid later problems. You will be seen by the Consultant in Restorative Dentistry either Mr Brindley or our Locum Consultant Mr Farooq, you may be referred to our Dental Therapist Rachael for further treatment. During your appointment with the Consultant, you may have an xray taken and a discussion about your teeth and gums.

During Radiotherapy

Saliva moistens and lubricates the mouth. It protects against tooth decay and erosion/sensitivity. It also aids swallowing and speech. Radiotherapy frequency damages the glands which produce saliva and can make your mouth dry. Mucositis is a common side effect during radiotherapy, it affects the lining of your mouth and can cause mouth ulcers and pain or difficulty in swallowing.

During Chemotherapy

Chemotherapy can also cause mucositis, this is when the linings in your mouth and digestive tract become inflamed, this can be painful- try using the Difflam mouthwash or ask for advice on the radiotherapy or chemotherapy department. Chemotherapy can also reduce the white cell count which may make you prone to dental infections.

What can I expect during cancer treatment?

About two weeks after the start of treatment you may notice an increase in mouth ulcers and mouth soreness, your mouth may feel uncomfortable towards the end of treatment and for up to 6 weeks after the completion of your treatment. Your mouth may also become dry and your taste can be affected. These changes will make it difficult to swallow, eat and clean your teeth.

What Might happen?

Short term effects

  • Dry mouth (but can also be long term)
  • Altered taste
  • Difficulty swallowing
  • Sore mouth
  • Coated tongue
  • Fungal infections

Long term effects

  • Tooth decay
  • Teeth erosion
What to Avoid
  • Fizzy drinks and flavoured water- these can contain lots of sugar which can damage your teeth, try to drink as much plain water as possible to prevent dental decay and erosion
  • Food or drinks containing sugar should be avoided in between meal times, especially 1 hour before bedtime
  • Check with your doctor for alternative sugar free medicines
  • Avoid tobacco products including vaping
  • Avoid alcohol and products containing alcohol
  • Avoid spicy/acidic foods
  • Do not scrub your teeth, brush gently
  • Avoid drinks with caffeine like tea- switch to decaffeinated, this may help with a dry mouth.
What can I do?
  • Take regular sips of water to keep your mouth moist (bottled water tastes better)
  • Brush your teeth and tongue 3 x daily after meals with a soft small headed toothbrush. If the bristles are too rigid soften them in warm water.
  • When possible use the interdental brushes / floss advised by your hygienist to clean the spaces in between your teeth.
  • Brush with Duraphat 5000ppm toothpaste spit out after brushing, (do not rinse)
  • Difflam Oral rinse 4 x daily during your treatment– may help with soreness. (on prescription)
  • To reduce bacteria levels, use alcohol free Corsodyl (chlorhexidine) mouthwash 2 x daily, dilute if needed.
  • Chew sugar free chewing gum to encourage saliva flow
  • Have dietary foods such as milk or cheese at the end of meals to help neutralise any acid in your mouth.
  • A teaspoon of sodium bicarbonate in a cup of warm water can be used as a mouthwash and help with a coated tongue.
  • Soft, chilled foods and adding gravy/sauces to food may help with swallowing.

Prevention of Dental Decay

If you find it difficult to reduce your sugar intake remember the frequency of sugar is worse than the actual amount consumed, therefore sugary foods/sugary drink consumed over a short period of time is less harmful than if they are eaten over a period of hours

Things to watch out for:

  • Ensure (nutritional drinks)– these are needed as part of your recovery but you should try consume within 5-10mins to minimize the risk of dental decay.
  • carbonated drinks
  • Tea and coffee containing sugar (swap for sweeteners)

Other things to consider

  • Reduce excessive periods of sugar intake per day, stick to meal times only.
  • Improve oral hygiene including tooth brushing technique and interdental cleaning.
  • Check for ‘hidden sugars’ in processed foods
  • Check for medications containing sugar. If in doubt check with your dietician.
