Adult teeth start to form under the baby teeth. After the baby teeth are lost, the adult teeth will come in through the gums.
Most children go through a stage when they have a mix of primary and permanent teeth. During this time the smile can look uneven, with some big teeth, some small teeth, some crowded teeth or maybe even some missing teeth. Try not to worry. Smiles often even out once all the permanent teeth are in place.
When your child is about age seven, the dentist will do a “bite check” to make sure your child’s adult teeth are coming in properly and that the back teeth are working together the way they should. You dentist may also take an x-ray of the teeth. If your child’s teeth or bite need treatment, it’s best to get an early start.
