Purpose?
Describing a bite systematically.
← All explanationsAngle classes
What do Angle Class I, II or III say about my bite?
Angle classes mainly describe how the first permanent upper and lower molars meet. They help describe a bite. The class alone cannot establish whether treatment is needed or which treatment is appropriate.

Class I
The molars have the usual relationship. Individual teeth may nevertheless be crowded, rotated or spaced.
Class II
The lower molars sit further back relative to the upper molars. Incisor position needs a separate description.
Class III
The lower molars sit relatively further forwards. Tooth position, jaw relationship and growth are assessed together.

Bite class and diagnosis
An Angle class is a description, not a complete diagnosis or a severity score.
Quick answers
Does Class I mean every tooth is straight?
No. It does not describe every tooth position or every bite problem.
Does Class II automatically mean a small lower jaw?
No. The dental relationship alone does not establish a particular jaw size.
Can I identify my class from a selfie?
Not reliably. Tooth contacts need examination, with further records guided by the findings.
