Overbite, inward, very small teeth. had resin bonding for 10 of upper and 6 of lower teeth and made them longer. my molars have no contact chew proble?

Posterior Contact: If your molars are not contacting you will be putting excess force on the recently bonded teeth. Please have your dentist reevaluate.

Occlusion: It's difficult to answer your question properly without actually seeing your entire bite, size and position of front teeth and quality of bonding. Best advice is to consult with Orthodontist if available. What you have had done is basically esthetic improvement but not a comprehensive approach to occlusion and function. Big bonded fillings on small teeth have guarded prognosis-can break easily.

Overall Rx: Sometimes malposed or anomalously shaped teeth require more than just cosmetics. Would suggest evaluation by Orthodontist (initial exam usually free) who is trained to create the best possible platform on which to do restorative treatment. You may also want to consider evaluation by Prosthodontist, specialist in reshaping and replacing teeth. Team Orthodontist + Prosthodontist = best treatment.

A Pickle!!: Good afternoon; Can't remain in this dental position; require posterior dental contact otherwise jaw pain and headaches may occur. Could have posterior teeth onlayed or crowned; however, these back teeth need to be in contact when you are not eating. The anterior composites will eventually fracture without posterior support.

One for the team.: This sounds like a more complex problem than esthetics. You need to consult a dentist who works with occlusion (bite) and TMJ (joint) therapy and is part of a team which includes an orthodontist (and possibly a surgeon, sleep physician, and ENT). While you may not need each of these people, you will need a team to coordinate all the pieces and solve your issues definitively.
