Common Orthodontic Problems
Class I
The posterior (back) teeth fit together well. The anterior (front) teeth may be crowded or not occlude properly. The teeth may be too large, too small, or the permanent teeth may not have enough room to erupt.
Class II
There is a discrepancy between the upper and lower jaw. The lower jaw is smaller compared to the upper. This may occur if the teeth are in the wrong position or there may be a different growth pattern between the upper and lower jaws.
Class III
There is a discrepancy between the upper and lower jaw. The lower jaw is larger compared to the upper. This may occur if the teeth are in the wrong position or there may be a different growth pattern between the upper and lower jaws.
Openbite
Openbite means that the upper and lower teeth are not touching. This can occur with the posterior (back) teeth or anterior (front) teeth.
Overbite (deep bite)
Overbite means that the upper anterior teeth overlap the lower anterior teeth in excess.
Crossbite
Crossbite means the upper teeth fit to the inside of the lower teeth. This can occur with one tooth or several. Crossbites can be in the anterior or posterior.
Spacing
There is a discrepancy between the amount of bone and the size of the teeth. Spacing causes food to push against the gum tissue. Over time this may lead to gum recession. Many patients are sensitive to the aesthetics of spacing.
Crowding
There is a discrepancy between the amount of bone and the size of the teeth. Brushing and flossing can be challenging with crowded teeth, resulting in tooth decay and gum disease. Many patients are sensitive to the aesthetics of crowding.
Ideal
An ideal bite will be aesthetically pleasing and all the teeth will function well, upper to lower, anterior to posterior.
