Notice that when biting from the side, the teeth fit together similarly to the teeth of a zipper. This provides a stable bite where most teeth occlude (bite) against two other teeth. Notice the mild overbite where the front teeth occlude. Many patients and parents come into the office complaining about their overbites, only to be told that their mild overbite is normal. If there is no overbite, teeth will wear down abnormally so having a mild overbite actually protects the teeth from abnormal wear. Of course, having a large overbite can be problematic.
Now that you understand what a set of ideal teeth and bite look like, you will hopefully be able to spot orthodontic problems better. Follow the links below to see Common Orthodontic Problems in Children or Teens and Adults.
