TADs to Move Jaw Up?

I would recommend that you talk to several orthodontists if you want other opinions and research it very carefully.  T.A.D.s could definitely be used, they would reduce the gum exposure in the smile line and the results should be fairly stable.  It is also important however, that YOU decide how you like your smile now, and what you want it to be like later in life.  In the photograph the smile shows some gum but looks pretty good to me now.  A smile showing more gum is considered more "youthful" up to a point.   The fact that you show more gum now may be a significant advantage when you are 50 years old and everybody else needs a face lift because they don't show enough of their upper teeth but you still do and still have a more "youthful" look than they do.  As we get older it is normal to show less and less gum and less and less of the upper teeth until when we are old we mostly show only the lower front teeth.  Look around at older people and you will see that in many cases you can't see their upper teeth at all or very little.  There may be a time in your life when showing a little more gum and a little more teeth may be an advantage.  You might delay the aging process a little bit by going with what you have.

Dr Kazemi below has does a very good job addressing the issue in very concise fashion.  A gummy smile is often caused by a skeletal issue.  The upper jaw may sit to low in position compared to what is considered "normal"  That being said if you do not mind showing gums when you smile then you do not need to do anything about it.  If it bothers you must have a consultation with both a Board Certified Oral & Maxillofacial Surgeon as well as an orthodontist. If you show gums at rest then it is a skeletal issue.  A Rest photo would be helpful.  Using TADS alone will be very difficult to fix this issue and you will probably be unhappy.  Also there are some dentists here advocating the use of Botox and Gum Surgery.  Be Very Weary of improperly trained individuals placing botox for high smile lines, also be very weary of "gum surgery" for this issue since you may wind up with very large appearing teeth.  You need to address the true issue before going through with treatment.  Seek the advice of a board certified oral & maxillofacial surgeon

If you show “too much gum” and want to know what is possible, then you should see both an Orthodontist and an Oral Surgeon for evaluation. Gummy smiles are usually  “youthful” smiles and it is important to understand what is too gummy or in medical terms, what is a long upper jaw, or Maxilla. TAD’s are small bone screws that can be useful to alter a single tooth position but not an entire jawbone. Botox or Dysport will help lengthen an overactive upper lip but is usually not indicated. If the problem is that your teeth are too short then a gum trim may be in order. More than likely, you are maxillary hypertrophic – long upper jaw, and the answer is Jaw Surgery to shorten the bone and create the correct jaw relationship while keeping a youthful look. See your local Surgeon who does craniofacial or Orthognathic surgery and they will guide you as to the correct diagnosis and a referral to an orthodontist as well.
