During laminate treatment

My teeth are yellow, and my front teeth are also spaced apart, so the resin filling has fallen out, making them look slightly separated.

Lately, a lot of people are getting laminate veneers.

To get a laminate, you need to grind down your teeth, and I want to know if there is any sensation or pain.

And I heard that nerve damage can occur after getting a laminate; I'm curious about how true that is.
