Definitely, wisdom teeth can be useful for chewing – if they have completely erupted in the correct position having enough space in the jaw. If this is not the case, you have to think about wisdom teeth removal.
Why wisdom teeth removal is needed?
In some cases, the patient’s jaw is not large enough and wisdom teeth often cannot erupt in the correct position. Then there is a risk of caries development of the adjacent tooth, gingivitis, abscess, cysts and, in very rare cases, a tumor may develop from a cyst.
Orthodontic indications: the force that erupting wisdom teeth can have can sometimes lead to a shift in the dentition, which in its turn leads to the front teeth crowding.
