Prior to having your full mouth reconstruction, it would have been highly advisable to have orthodontics dental treatment first, prior to placing full mouth crowns. You are trying to correct the skeletal discrepancy of under developed upper jaw bone with fabrication of crowns, in which the teeth will look long, flared and angled. There are some cosmetic dentistry illusions we as cosmetic dentist can use to make it a pleasing smile, but not perfect. Orthodontic, or orthognathic surgery options must have been discussed with you, and also the looks of the final outcome prior to starting full mouth crowns.I am guessing that you had a pseudo class 3 bite in which the dentist tried jumping all your upper teeth over the lower teeth, and as the result of that you have flared, long upper teeth.At this point if you are not happy, you still need to consult an orthodontist and a maxillofacial surgeon, for solution and possibly redo most of your porcelain crowns after their treatment.In cases of full mouth crowns with bite issues, in my practice, it is a must that I would do a full wax-up of the final result, so you as the patient would know what you will be getting, all your questions and concerns must be answered to your satisfaction and you sign off on what I can achieve for you. For cases with bite issue, I would have referred you for consult and treatment with orthodontist prior to starting any full cosmetic dentistry.
