There's no need to do this. My decayed tooth has been filled for 15 years. At that time, the doctor also advised me to wear braces, but I didn't do it because it was too expensive. For more than ten years, my teeth have been very good, and there have been no accidents, except that I lost my teeth and filled them again. Just try to bite hard food with the filled teeth as little as possible, pay attention to oral hygiene and prevent new tooth decay!
