There are some things you can do to help ease the symptoms of mucositis while you’re having chemotherapy or radiotherapy. Do brush your teeth with a soft toothbrush at least twice a day – gently clean between your teeth using floss once a day if you can rinse your mouth with warm water, salt water, or mild alcohol-free mouthwash several times a day chew sugar-free gum or suck ice cubes, crushed ice or ice lollies if your mouth is dry eat soft, moist foods, like soup, jelly or soft fruit use lip balm to stop your lips getting dry leave out dentures if you wear them, and keep them clean and moist even when you're not wearing them drink plenty of water, eat less fibre and take diarrhoea medicine as advised by a doctor or pharmacist (if you have diarrhoea) Don’t do not smoke do not use alcohol-based mouthwashes do not eat hot food do not eat spicy, acidic, rough or hard foods like crisps and crusty bread do not drink hot, fizzy or alcoholic drinks How to rinse with salt water Dissolve half a teaspoon of salt in a glass of warm water – warm water helps salt dissolve. Rinse your mouth with the solution, then spit it out – do not swallow it. Repeat as often as you like.

If you have mucositis in your mouth, treatments your care team may offer include: painkillers, which may be tablets, mouthwashes, gels or sprays mouthwashes that clean, numb and protect your mouth sprays or gels to keep your mouth moist (saliva substitutes) If you have mucositis in your gut, the treatments recommended will depend on your symptoms and how severe they are. For example, you may be given medicines to: relax your gut if you have stomach cramps or bloating ease pain and reduce stomach acid stop diarrhoea or reduce soreness inside your bottom (rectum) Low-level laser therapy There’s also a treatment for oral mucositis called low-level laser therapy. A small probe that produces infra-red light is either put inside your mouth or outside your mouth, close to your cheek. The light can help prevent and treat mucositis. The treatment can be given before and during a course of chemotherapy or radiotherapy. Each session lasts 20 to 30 minutes.

If you have side effects from cancer treatment, like mucositis, you may find it helps to talk to people in a similar situation. Ask your care team about support groups in your area. Some cancer charities also have online forums that you may find helpful.
