Dr. Goldstein is an exceptional dentist! When I first met him, I instantly got a good feeling from him. He is honest and skilled. He does not try to sell stuff to you and makes sure to go over all the options that fit your budget to meet your expectations. I used to go to a dentist in Norcross and recently decided to switch. So far, it has been the best decision I've made in a long time. They truly treat everyone like family, from the moment you walk in to the moment you walk out and even when they reach out to schedule appointments.
There is a slight chance you may have a lisp for a few days to a few weeks, if your veneers are made longer than your natural teeth. Not every patient developes the lisp, but every patient looses it with in a few weeks.
It sounds as if the smooth glaze of the ceramic was adjusted when they corrected your bite. Ask the dentist to polish the area, it is a quick fix,
looking at the photo it appears that you are moving your lower jaw forward when smiling. Orthodontics may not be the answer for you.
Yes, this is a problem. Your back teeth should touch slightly before your front teeth do. the back teeth are stronger snd need to touch for chewing efficiency. When the front touch first they can splay out and make your smile less attractive.
Unfortunately, it does appear that a new orhtodontic consult would be advisable. The current orthodontist should have closed the spaces, so having a second pair of eyes on the problem will probably fix it with new aligners or braces.
