What kind of profile to expect after extractions for bi-maxillary protrusion?

It's very easy to change a tooth's shape with today's bonded composite materials. When replacing an old filling, for various reasons, the new one won't be exactly like the old one. It's possible, for instance, that more tooth structure had to be removed. Explain your concerns to your dentist, it...

My suggestion would be to perform veneers, we can change shape, size ,and make those teeth more straight ,this procedure can be done within 2 appointments, they are made of porcelain. I hope this helps., but yes you have a solution.

You may find that the retainer takes a little more effort to go in, as you may have had a slight shift but not adversely where wearing the retainer will not be possible.  I would to sweat it.  Good luck
