No, back teeth, including wisdom teeth, do not typically grow back after they have been removed.
While the primary back teeth do not regenerate, understanding some related concepts helps clarify the issue:
-
Permanent Teeth: Humans have two sets of teeth: primary (baby) teeth and permanent teeth. Once a permanent tooth, including a back tooth, is lost or extracted, it does not naturally grow back.
-
Wisdom Teeth Exception: According to reference, "Wisdom teeth do not grow back after they've been removed."
-
Supernumerary Teeth: Although extracted wisdom teeth do not regrow, a person can have extra teeth called supernumerary teeth. The reference mentions that "It is possible, however, for someone to have more than the typical four wisdom teeth. These extra teeth, which can erupt after your original wisdom teeth have been extracted, are called supernumerary teeth." Therefore, it might seem like a wisdom tooth has grown back when it is really a new, extra tooth.
In summary, back teeth, including wisdom teeth, do not regenerate. The appearance of a new tooth in the back of the mouth after extraction is likely a supernumerary tooth.
