I'm 24 and half some pretty bad discoloration of my teeth due to soda and neglect. I'm rather self-conscious about it and would like to have it fixed. I don't think a simple bleaching would fix the problem. So, I was thinking of capping 6-8 teeth with PVs. I undertand it's rather pricey but it would be worth it for the self-confidence. However, I'm concerned about damage to the teeth caused by the sanding process required by PVs and the longevity of the PVs. I don't want to damage my teeth so early in life and I don't want to have to pay to re-do my PVs in 3 years. Has anyone had any experience with this? Any advice (online resources) is appreciated. Thanks!
