My teeth have a yellow shade because of a wrong high dose antibiotic treatment I had as a child. I am now 43 and after many years thought I could give myself shiny bright teeth as a present. There is nothing wrong with the shapes of my teeth. The doctor I consulted said whitening would not work for my problem and porcelain would be the answer. Unfortunately I don’t remember what he suggested exactly but he said this porcelain on my front teeth would have to be renewed every 10 years. As the best quality treatment cost around 20,000 USD!!! (I’d try to go with the best) renewing this every 10 years is out of the question. Is it really necessary to renew? How long do porcelain veneers and crowns last?
