The teeth that sit at the back of each jaw are called wisdom teeth. They can cause various problems by, for example, easily becoming inflamed and injuring the tooth in front and causing problems with the gums. In addition, it can be difficult to keep wisdom teeth clean.
It is common for young children to bite themselves or others. Often this is because the child has not yet learned to express himself in words, and the biting becomes a way to make contact and show emotions. Young children do not bite to be mean or troublesome. They often have close feelings and can be impulsive. If your child bits, it is important that you mark immediately, but calmly. A child who has been bitten rarely needs care.
