Baby teeth usually start to form before birth and start to emerge after about 6 months. All 20 of a child's milk teeth should erupt by the age of 2½. The milk teeth also have a crucial role in maintaining space. A baby tooth that comes out too early can cause serious problems later in the development of healthy teeth. It is recommended to start introducing children to the dentist as early as possible. It is a good idea to take them to the dentist more often, at regular intervals as recommended by the dentist. This will accustom them to the sounds, smells and external influences in the dental surgery and prepare them for future examinations. The earlier you start, the more relaxed even your tiny child will be in the chair.
