I have veneers on my front 2 teeth to fill a gap. I am a nighttime grinder/clencher. I wear a night guard that was fitted by my dentist every single night. Prior to getting it, I had ground down my canine teeth and I hate the look of the flat tooth. My R canine, is shorter than my R lateral incisor and my first molar. Can I get porcelain veneers after already having them put on my 2 front teeth? I just had the front 2 done 2 years ago, so I don't want to spend the money to have all 4 done again.
