When the upper row of teeth overlaps the lower excessively, this is called an overbite. Overbites cause the upper jaw to extend forward creating a faulty bite, as well as a less attractive appearance. Overbites can cause problems with the upper and lower teeth not meeting properly. An orthodontic specialist can offer solutions.
An overbite can eventually cause undue pressure and wear on lower teeth. Then the lower teeth are in jeopardy for earlier degradation. The upper teeth that stick out are more vulnerable to trauma. Another issue with an overbite is that it can be the cause of decreased self confidence.
There are several treatments available to correct overbites. Braces or aligners are used, sometimes in conjunction with extraction of certain teeth or even jaw surgery in severe cases.
