Hey. After a long time being uncomfortable with my teeth gap, i'v decided to go see a dentist to see what could improve my smile. The dentist suggest putting on 4 or 6 Lumineers (2) Veneers on my top jaw to remove to gaps. I would like to ask if the treatment is the best for me, and if so how long does these veneers can last? (I'm 20 years old btw) Thank you! :)
