While many people think braces are only for straightening teeth, they actually help deal with many other problems.
Crowded Teeth: Sometimes your mouth is not big enough to hold all your teeth in the right place. Crowded teeth may become impacted and affect your bite. Crowding can be corrected by removal of teeth as well as braces.
Overbite: Upper teeth extend too far out over the lower teeth. The gap between the upper and lower teeth may lead you to injure your gums or lips. It can also cause your lips to be pushed forward meaning you are not able to close your lips completely over your teeth.
Underbite: Your lower teeth extend in front of your upper teeth. It is usually caused by having a lower jaw longer than the upper jaw.
Crossbite: Some of your upper teeth bite down inside the lower teeth but others bite down correctly. If you suffer from this, you may have problems chewing.
Open Bite: Your lower and upper incisor teeth do not touch when you bite down. This puts a lot of pressure on the back teeth when chewing and biting. If you suffer from this, you might rub your teeth together without intending to.
Space Problems: If you have teeth that are smaller than normal, or you have lost important teeth, you may have spacing problems. The teeth may spread out and, if the spaces become too large, you might have problems biting and chewing. However, the main issue with space problems is often cosmetic.
