Uneven teeth at the end of alignment are common in adult patients. This is because, while the teeth were out of position before orthodontic treatment, their biting edges became worn and chipped, and sometimes the teeth even fractured. Once these teeth are straightened, the defects in their shape become more noticeable. In such cases, bonding is most often recommended to restore the shape of the affected tooth or teeth. Shortened teeth have usually lost some of their enamel, and adding material to them restores their natural appearance. If the patient wants a solution without bonding or adding material to the teeth, shortening the longer tooth can be considered, although this means artificially wearing down and ageing that tooth, so unless the tooth is unnaturally long, we do not recommend it.
This answer is for general information. Your own case needs an examination by an orthodontist.
