Cherubism is a rare condition that affects the bones in your face. Sometimes, when you are born, your body makes too many cells that turn into bone, and this makes the bones in your face grow bigger than they should be.
When this happens, it can make your cheeks look puffy or swollen, like a little baby's face. This is why it is called 'cherubism.'
Cherubism can make it harder for you to eat, talk or breathe properly because the bones in your face are too big. Sometimes, it can also make it hard for you to see, or your teeth may grow in funny ways.
Doctors can help people with Cherubism by giving medicines or even surgery to help reduce the size of the bones in the face, so that you can feel better and do things like eating and talking more easily. It is important to talk to a doctor if you think you may have Cherubism, so that they can help you get the right treatment.
