Class I occlusion
Class II occlusion
Top teeth too far ahead of lower teeth
Top teeth too far behind lower teeth
Insufficient overlap of front teeth
Too much overlap of front teeth
The amount the upper teeth are ahead of the lower teeth. Ideally should be 2-3 mm.
The upper front tooth is inside the lower teeth.
The upper back teeth are inside the lower teeth.
A crossbite when upper and lower teeth do not touch.
The four front teeth, both top and bottom. They consist of the central and lateral incisors.
a pointed tooth between the incisors and premolars of humans
a tooth situated between the canine and the molar teeth. An adult human normally has eight, two in each quadrant
The grinding teeth at the back of the mouth. An adult normally has 12, three in each quadrant. The last one in each quadrant is called the wisdom tooth.
Better known as baby teeth. There are usually 20. Orthodontists label them with letters instead of numbers.
These are permanent teeth. These include four central incisors, four lateral incisors, eight premolars, four canines and eight molars. The last of the permanent teeth to appear are called "third molars," or "wisdom teeth." They usu- ally begin to erupt—pushing their way through the gums—between ages 17 and 21 years. We have 32 adult teeth normally.
Better known as wisdom teeth, these teeth don't erupt (if they erupt) until late teens or early adulthood. (i.e. when they are wiser)
Dentists and orthodontists break the mouth into four quadrants. Upper right (UR), Upper left (UL), Lower left (LL) and lower right (LR)
Adult tooth numbering in orthodontics
Orthodontists number teeth by Quadrant (UR, UL, LL, LR) and the number the tooth is from the front.
Adult tooth numbering in dentistry
Dentists number starting from 1 to 32. 1 begins at the 3rd molar in the upper right, proceeds across the upper jaw. 17 begins in the lower left and proceeds across the lower jaw.
Baby teeth numbering in orthodontics
Orthodontists number these teeth by Quadrant (UR, UL, LL, LR) and uses a letter starting with "a" moving from midline back.
Baby teeth numbering in dentistry
Dentists letter these teeth from A to T, starting in the upper right and ending in the lower right.
