Will your teeth shift if you bite on something hard? i bit into a chicken bone and im worried my teeth have shifted. does it shift back?

Tooth mobility: Teeth are not like steel poles cemented in concrete. There is a living membrane called the periodontal ligament that connect the bone to the root of the tooth. This allows for minor tooth movement which is normal. Teeth are constantly shifting around ever so slightly and this maintains the bone support. Also, the better the occlusion (bite) the less chance of tooth movement over time.

Shifting: If your gums and the underlying bone are healthy, eating should not cause shifting. If you have a malocclusion, however, and teeth are not properly supported by bone, they can shift on their own at any time. If teeth shift there is no mechanism for self-correction. See your Dentist for an evaluation as to whether there is a problem , and if so what is the appropriate treatment.
