Your child’s primary teeth, also called baby teeth, are essential in the development and placement of their permanent teeth. Primary teeth maintain the spaces where permanent teeth will erupt and help develop proper speech patterns that would otherwise be difficult. Without maintenance of these spaces, crowding and misalignment can occur, resulting in more complicated treatment later. Baby teeth also are primers for teaching your child good oral care habits. It is important to take care of your child’s primary teeth. Even though primary teeth last only a few years, decay, cavities and infection can take its toll and may require expensive treatment to repair.
