Hi, I have broken one of my front teeth when I was about 10 years old, my dentist put one of these cosmetic fillings that you put around a pin that he inserts in your tooth, when I became 16 I changed that filling because it was starting to decay and my tooth looked much better. However, when I turned 18 I chipped a small piece of that filling and now it doesn’t look as good as it used to be. when I went to my dentist to change it again he told that the only way to replace is to file the whole tooth and put a crown on it, but he also discouraged me to do so because of the nature of putting a crown on a fore tooth and how it would be hard to fix when it changes color. His opinion was is to keep my current filling for as long as I can then put the filling so it can last me longer. Is there any possible way to fix my tooth without reserving to crowns that would be much stable and less risky. If not is there any possible way to fix my current filling so it can last me longer, something that will make it feel and look better?

thank you very much
