Will I Benefit from Gum Contouring? (photo)

You are an excellent candidate for a laser or electrosurgical gingivectomy to improve the visible shape of the front four teeth.  Minimal recontouring on 8 and ( will give significant improvement.Tooth number 7 will have the most dramatic effect during a full smile and a millimeter to a millimeter and a half reduction would be sufficient.Easy and practically pain free with a laser.  Slight discomfort with electrosurge unit.Recontouring the incisal edges would also improve smile with minimal time or expense.
You do have  a narrow smile and dark buccal corridors as well and the use of a DNA Appliance and Epigenetic Orthopedics might give the best results and increase your airway and can help if you have headaches, snoring or TMJ disorders.Ira L Shapira DDS

From the pictures you have provided, You do not have much excess gingiva (gum), so doing crown lengthening or gum re contouring might lead to recession in your case, unless it is combined with veneers.   But again this is just looking at the pics.  it is better for you to be evaluated, xrays and measurements of your gum will be very helpful.

After this evaluation, if doable, a gingivectomy (gum re contouring), or crown lengthening ( e contouring of the gum and the bone) on your right lateral incisor ( the shortest tooth on the left side in the picture, beside the canine) will improve your smile.

our guidelines for esthetic smile is to have, the canines and the centrals with the same gum height, and then the lateral incisors (the teeth in between the canines and the central incisors ) with 1 mm lower gum line.  

so in your case, I think you are pretty close to this, except for your right lateral incisor. the gum for this tooth could be re contoured to the level oft he mirror tooth ( the lateral on your left).

 

It is difficult to tell from your photos without xrays or a clinical exam, but it appears the cause of your gummy smile is skeletal- meaning it has to do with the development of your jaw. Gum contouring on your right side can help the esthetics, but it will not fully fix the problem. Speak with your periodontist about options.
