Crowded teeth are teeth that have erupted too close together, resulting in crooked teeth and an abnormal bite. Crowded teeth can occur with baby teeth or with adult teeth. If a person has crowded teeth as a child, they are far more likely to have crowded teeth as their adult teeth erupt.
What can cause teeth crowding?
The causes of crowded teeth are almost always genetic. The upper and/or the lower jaw can be too small or the teeth themselves can be too large for an otherwise normal-sized jaw. Either problem can happen and can affect the way the teeth look. Other causes of overcrowded teeth include a cleft lip and palate, having extra teeth beyond the number of teeth you’re supposed to have, tumors of the mouth and jaw or problems with the position of the teeth after a jaw fracture that doesn’t heal well.
Can teeth crowding be prevented?
There are few ways to prevent crowded teeth. Dentists can do extraction of some teeth when a child is first getting teeth or when the adult teeth are coming in so that the rest of the teeth fit. It still might affect the bite but will help the new teeth coming in have space and not be crooked when they erupt.
