When you are around 6-7 years old, your "baby" teeth will start to fall out because your "grown-up" teeth are beginning to form underneath and they are pushing your baby teeth out. You will see that your grown up teeth are quite a bit bigger than your baby teeth.

TONSILLITIS - Tonsils are at the back of the mouth and are used to filter out harmful germs. Sometimes when they have too many germs to filter they become sore. You will have trouble swallowing and may feel like you have the flu. You will have to get plenty of rest and drink into of soothing fluids, and sometimes you will have to go to the doctor for him to check your throat and give you some medicine.

TOOTHACHE - Can be caused when you have a cavity. Your tooth feels sore to touch, and ice cream or a hot drink touching your teeth can make you jump. You might have fallen and chipped off a piece of your tooth. If this is what is happening, you will have to visit the dentist to fix it. Inside your teeth there are things called nerves and when these get opened up they are very sore. The dentist will cover them again with a filling.
