A baby will begin to gain teeth around 6 months of age, and this will continue until around the age of 3. Children will eventually lose all of their baby teeth between 6-12 years old.  If a baby tooth is lost too early, it can cause serious crowding problems for the developing adult teeth, as well as negatively impacts the jaw’s muscle and bone development. Occasionally, some baby teeth never fall out, and for this reason, an adult tooth cannot replace it. These baby teeth that never fall out are called retained teeth, and although they are typically harmless, they can cause some dental issues.  We would be happy to do a complimentary evaluation to see if your baby teeth are creating issues for you that orthodontics could potentially correct.
