A sore mouth is a common side effect of cancer treatment or the effects of advanced cancer. It can make someone feel very unwell and uncomfortable.
If your relative or friend's mouth is too sore to use an ordinary toothpaste and toothbrush, try using a soft toothbrush and mouth rinses. If their lips are dry, a lip balm can be useful.
Mouth ulcers and thrush are common. If their mouth becomes very sore or coated, tell the GP, specialist palliative care team or district nurse. It is very important these symptoms are treated. There are mouthwashes, tablets, gels or pellets that can help relieve the symptoms. If dental treatment is needed, ask the dentist if they can do a home visit. You may need to pay for this.
