Open bite
An open bite is when the upper and lower front teeth do not touch when the mouth is closed, leaving a gap between them.
An open bite is a type of malocclusion. With an open bite, your upper and lower front teeth do not touch when you close your mouth. A gap remains between them. Some people have this at the back teeth instead.
Causes of bite problems include crowded or crooked teeth, or upper and lower jaws that do not align the way they should. Habits such as thumb sucking can play a part in some bites.
A dentist can look at the bite and explain the cause. Treatment may include braces or clear aligners are an option. A dentist can look at your bite and talk with you about choices. Our office describes straightening on its teeth straightening page. See also overbite.
