This varies between patients; some children have growth problems, which are often caused by thumb sucking or soothers. If a child’s teeth adhere to this problem, a brace (retainer types) can be fitted as early as is suitable. These days, it is rare to wait until all the baby teeth are gone as we can now accurately predict if a child will have crowding or crooked teeth. If this is the case, a brace (retainer type) can easily be custom fitted to help solve the problem from an early age.
Train-tracks: These are only fitted when the baby teeth are gone. They are excellent for correcting the level and alignment of the teeth.
