You want your child to have a beautiful, straight, even smile. Most people aren't born with that smile. In order to get it, your child is going to need to have some help, in the form of orthodontics. If you are going to go with orthodontics for your child, there are a number of options out there. You can talk to your child's orthodontist to see what options they suggest would work best for your child.
One option is to go with invisible braces. These aren't traditional braces but are generally aligner trays that your child would wear for the majority of the day. They can take the tray out when they are eating, but other than that, they will need to wear them. The tray has been molded with the place that the teeth will go. When your child snaps it in, it will help their teeth move to the right place. Your child will have to use a series of trays because each one will make small adjustments. You can't make big adjustments all at once, but several small adjustments will add up over time and equal the big change.
Lingual braces can also act as invisible braces, mostly because they are on the inside of the teeth instead of the outside. That is, that they are on the tongue side of the mouth. These braces aren't as common, and they can have a learning curve to dealing with them because the tongue can get irritated by the brackets of the braces. However, in some situations, these might be the best choice to make.
The traditional braces are the brackets that are on the front of the teeth. They are adhered to the surface of the tooth and then have a wire that runs through each bracket until it gets to an anchor point, generally at the back of the mouth, attached to molars. The orthodontist will adjust the wire as necessary in order to make sure that the teeth are moving the way that they should. Your child may also have to wear rubber bands that run from one bracket in order to cause tension to move their teeth around to the right place.
If you want to make sure that your child has a beautiful smile, one way to do it is to go see an orthodontist and to get them braces.
