The American Association of Orthodontics, also known as the AAO, recommends children having a screening by seven years old.
Once you bring your child for a screening by this age, your pediatric dentist can precisely predict if your child is prone to having any dental issues in time like crooked teeth. By this age as well, your child’s molars will begin to develop and will create a back bite. Their jaw and teeth will also be developed to the point where your dentist can figure out if any issues will occur with their mouth. A possible case of open/overbite or crowding can occur for example if your child has incisors coming out at this time suddenly.
This prediction will not be permanent though and is dependent on how your child cares for their teeth in time. You and your dentist will have a job of observing how their teeth are developing to ensure proper growth. This can allow your child to have dental treatments early on in life to prevent any serious issues later on.
