Mouth ulcers in a young boy

My son has a tongue-tie

Question
My nine-year-old daughter, often gets blisters in her mouth.

Can you give me any explanation as to why?

What can be done about it when they appear?

Answer
Blisters in the mouth are common among children and can also occur in adults.

It is usually a harmless condition, even though it can be unpleasant.

The blisters might appear periodically and disappear by themselves. It is not known what causes them, but they can often be associated with eating sweets and chocolate.

Careful attention to oral hygiene can reduce the rate of occurence.

You should consult your GP or your dentist during an episode, so that an assessment can be made of your child's blisters and general wellbeing.

Yours sincerely

Dr John Pillinger, GP
