I chipped #9 when I was young. I've always got a bonding done but my natural tooth is starting to darken. I don't want RCT if I don't need it but my dentist suggested that and internal bleaching to lighten the tooth. I was leaning towards veneers for #8 & 9 but he said being 25 years old I'll be replacing them often. Which is better ?! Internal bleaching and RCT or veneers ?!
