I am 20 years old and I hope to go for my DDS. During my childhood, I didn't take the best care of my teeth. I have several cavities and I might have to get a crown on a tooth. I have changed my dental habits and believe that I now have very good oral hygiene, but I do have the old cavities and some enamel loss. I really would love for this this to be my career, but I think my dental past would be an issue. Any thoughts/advice would be appreciates. Thanks!
