I did mine strictly for cosmetic reasons too. Only thing that hurt was the numbing. For some reason it hurts more in the front of the mouth than the back. Just also be prepared that they will shave your tooth down. I did not know this and when I saw my reflection in the plastic cover for the light the dentists use I was caught off guard. I kind of looked like a jack-o-lantern.
They will also do molds of your teeth before and after. Then they will give you temporary veneers until the lab can make your permanent ones which took about 3 weeks for me. Then when the permanent veneers come in they cement those in.
Honestly I regret getting them. Whenever I touch them with my tongue, I just always wish that I had my original teeth back. I'm also paranoid that they are going to fall out but my dentist reassured me that my veneers are stronger than my original teeth. I admit they do look alot better and my smile looks better but, if I could do it again I'd only do it for a health reason not cosmetic.
