Is pulling teeth for an overjet good or bad?

It's an option: Removin teeth is a viable option to correct am excessive overjet. It's not the only option, since growth appliances can sometimes work as well. An orthodontist can make a good recommendation as to which option is best for your case.

Viable option: Is this the advice of an orthodontist? Some orthodontists do advocate extracting teeth to make more room in the mouth to correct malocclusion. It is usually the first bicuspid that is extracted. I see it all the time, and is a common treatment. If you are not comfortable with losing a tooth, you can always get a second opinion from a different orthodontist.

Not the best option: In most cases, an excessive overjet indicates a short lower jaw. Extracting teeth is an option, but not a good one. As a patient ages, into their 40's, adverse facial changes may occur as a result of extracting teeth for an overjet. The newer, better options include either distraction osteogenesis or jaw surgery to lengthen the lower jaw and avoid extracting any teeth.

Both (my opinion): Jaw surgery is a significant elective event. Doing so should not be done lightly. Saying removal of teeth may not be the best option does disservice to all the shades of gray. Max. Protrusion accounts for many, many overjets, if by tooth removal the naso-labial angle is improved: extract. In cases with a very mild recessed chin and lower crowding: align/rid overjet and think of a genioplasty.

Sometimes: Depends on many factors, including age of patient (growing or not), sagittal (front-to-back) jaw relationships, amount of over jet, lower incisor position, etc. There a limitations to effectiveness of all treatment modalities, and effectiveness vas limitations must be individually assessed. No orthodontist lakes to have teeth removed, but sometimes it's the best option.
