Although you lost them early in life, your main tooth, also known as baby teeth, is the foundation for permanent tooth development and placement. Primary teeth maintain the space for permanent tooth bursts and help form the proper speech patterns that would otherwise be difficult; if they were not maintained, crowding and dislocation would occur, leading to more complex treatments in the future. Baby teeth are also good oral care habits that guide your child. It is important to take care of your child's primary teeth. Even though the major teeth are only a few years old, decay, decay and infection can take their toll and may require expensive treatment to repair.
