I am looking for a temporary solution to 4 of my front teeth while I save for porcelain veneers. I am hoping to make it for 2-3 yrs. Right now I have a couple of fillings (I believe are bonding) that have yellowed (over many years), so it doesn't look great, although not too bad. However, I will need 2-3 (maybe 4) years to save for porcelain. I only drink red wine on the weekend. I do have coffee every day. Can I make it about 3 yrs with resin veneers without them staining too badly?
