When I Smile or Talk, You Can't See my Upper Teeth, Have to Forced Smile It?

The starting point is to discuss this with your sister who is a dentist and your nephew who is a max fax surgeon, they could offer invaluable advice or referral onwards.One dentist has commented that your ortho treatment went wrong; I would disagree with making such comments without full records. If you had unusually short teeth then your orthodontist would have told you so.My guess is that your upper jaw may be short vertically and so the teeth will not show when you smile.Depending on how far the teeth have to be to show then you could either have upper veneers to make the teeth longerupper surgical correction to bring the upper jaw down a littleboth decisions would require full consultations and time to consider actions

Thank you for your question, without pictures its difficult to give you an accurate diagnosis.
From what you described, it sounds like when you were younger, you were happy with your smile, and as you've aged, your teeth have disappeared.
 As we age, the muscles in our faces are not as toned and gravity sets in lengthening your upper lip by loss of elasticity. Also, teeth wear down getting shorter with time. This can be exacerbated by teeth grinding and malocclusion. 
I would see an expert cosmetic dentist to discuss what your best options may be. It may as simple as getting porcelain veneers, to lengthen your teeth and rejuvenate your smile. Or, you may benefit from an upper Lip Lift in combination with veneers. 
Good news is you can get this fixed while your still young and have a new smile that fits your age and face.

Hi:
Unfortunately without photo and X-ray it is difficult to give you accurate advice.  Please post photo and X-ray of the affected area.

Thank you for your question. Pictures would be helpful. Sounds like the teeth got worn out due to the edge to egde bite. If so, it is definetly possible to give you your smile back. It might require some crowns and veneers in order to achieve this. My advise is to schedule a consultation with a dentist, experienced in normalizing vertical dimension of the mouth. 

This could be one of several issues.  You may have a deficient lower facial height.  Your upper lip may be long or your muscles around your mouth may not open your lips wide enough to see.  Your teeth could be short and your upper and lower jaws too close together (deficient vertical dimension of jaws).  Before recommending any treatment it would be necessary to determine exactly which issue is your problem.  Then and appropriate treatment(s) could be recommended.It may be just an issue of making your teeth longer with veneers or crowns.Or, jaw surgery and orthodontics.Maybe plastic surgery around your mouth?One thing to remember is everyone is different.  Certainly Julia Roberts and Regis Philbun have altogether different kinds of mouths and smiles and teeth and most would certainly say they are normal.  I know you just want to be the best that you can be.  First, talk with a couple cosmetic dentists to determine if it is a dental problem or other type of problem.  If not a dental problem, they certainly can guide you to the best physician or dentist to treat your particular problem.Good luck!
