Does Early Orthodontic Treatment Prevent the Need for Braces Later?

Brother and SisterOur family’s orthodontist recommended early treatment for my daughter. What kinds of problems can be fixed with early treatment? Will having braces at an early age prevent the need for full braces later?

The American Association of Orthodontists recommends that all children be seen at age 7 so that the growth and development of their smile can be evaluated. By age 7 most children have all four of their 6-year-molars and four central incisors too. With these teeth in place, your doctor can identify most of the orthodontic problems your child may have and can counsel you on whether early treatment would be beneficial. What kinds of problems should be addressed at age 7 when your child still has lots of baby teeth?

The first type of problem has to do with the amount of space available. Crowded teeth overlap each other and cannot be lined up straight. Teeth with too much space between them may actually be preventing other permanent teeth from coming into the mouth. Crowding in the front of the mouth is obvious. Crowding in the back of the mouth may not be visible without an x-ray. Moderate crowding and spacing problems should be addressed at an early age so that the remaining permanent teeth can come in correctly.

The upper teeth are naturally wider because they lay on the outside of the bottom ones when lined up correctly. When the top back teeth are on the inside of the lower ones (crossed over), we call that a posterior crossbite. When the upper front teeth are behind the lower front teeth, we call this an anterior crossbite or an underbite. Teeth in cross bite may reveal an underlying jaw problem that is best addressed at a young age.

The opposite of an underbite is an “overbite” (actually called excessive overjet). Mild overbites are common and not a concern until all the permanent teeth are in. Moderate to severe conditions can cause social problems for young patients and make them more susceptible to dental injuries because the teeth stick out. Although overbites cannot be totally eliminated until a child has finish growing, it is advisable to reduce their severity for reasons of safety and self-esteem.

Ideally the top front teeth overlap the bottom front teeth about half way. If they overlap too much, we call this a deep overbite or deep bite. If they don’t overlap at all, we call this an open bite. Both conditions may hint that there may be underlying jaw problems. An open bite may also be due to oral habits such as thumb-sucking that can harm your child’s dental development. Orthodontists can help young patients break such harmful habits.

Will early treatment guarantee that a child will not need treatment later? The answer is almost always no. Early treatment is commonly called two-phase treatment because more than 90 percent of children who undergo treatment at age seven or eight must finish when the remaining permanent teeth are in place. The typical Phase 1 patient finishes his first phase of treatment with 12 primary teeth remaining. The second phase cannot begin until all 12 of the remaining primary teeth are gone and the remaining 16 permanent ones have come in fully (around age 13). If a child has problems so severe at age 7 that they need interceptive care, the chances are pretty good that he or she will need to have the second phase of treatment to finish their smile.

The best way to look at two-phase treatment is this. Instead of waiting until your child is 13 years old and then putting him or her through two to three years of difficult treatment, your orthodontist is recommending an easier approach. Why not let him help your child over some of the biggest hurdles now, so that when all the adult teeth are in (junior high and high school) treatment will be easier, better, and faster? That is the goal of early treatment.
