Everything You Need To Know About Mouth Ulcers In Kids

There are certain health problems that all kids seem to get and mouth ulcers are one of them. These painful little bumps can cause a lot of discomfort for your child and if they keep coming back over and over, they soon become a big problem. The good news is, there are some simple ways that you can deal with mouth ulcers and stop them from coming back.

Read on to find out how to treat mouth ulcers in kids and how to stop them from coming up in the first place. 

How To Treat Mouth Ulcers

Catching them early helps with treatment a lot, so if your child is prone to mouth ulcers, you should check for them on a regular basis. If you notice one coming up, apply some mouth ulcer gel right away, so you can start treating it before it gets any bigger. This should deal with the problem easily if you keep applying until the ulcer goes down. However, you need to take certain precautions while it is healing. 

Be careful about what your child eats because salty and spicy foods will irritate the ulcer and cause them a lot of pain. You should also keep up with a good oral care routine to speed the healing process along. 

Follow these simple steps and you will be able to get rid of the ulcer, but how do you stop them from coming back?

What Causes Mouth Ulcers?

There are a number of things that could be causing your child’s recurring mouth ulcers, so take a look at this list and consider whether there are any changes you can make. 

Vitamin deficiencies

A poor diet is often the culprit when kids keep getting ulcers.

It’s very common for ulcers to be caused by a vitamin deficiency, so if you have a hard time getting your child to eat their vegetables, that may be the cause of their ulcers. Finding ways to improve their diet is important, but you can also try a multivitamin in the short term to help boost their vitamin levels. 

Injuries from braces

If your child wears braces, it’s likely that they are the cause of the ulcers.

When braces rub against the gums and cause damage, this can encourage ulcers to form. Sometimes, it’s just a case of letting them get used to the braces but if the problem persists, speak to the dentist about adjusting them to make them more comfortable. 


There are certain diseases that could cause mouth ulcers in children, like coeliac disease or inflammatory bowel disease. So, if your child keeps getting ulcers and you can’t work out why, it’s a good idea to take them to the doctor to get checked, just in case. 

Sometimes, mouth ulcers will come up for no reason and you just have to deal with them. But if you can manage these common causes, you can stop them from recurring.
