Soft enamel runs in the family. By my early 20s I had to have a similar procedure done on all my front teeth on the top because my real teeth were chipping and breaking. That was 30 years ago. The porcelain crowns are better looking and harder than my real teeth ever were. The only problem is one fell off in the sink when brushing my teeth about 10 years ago. The dentist just glued it back on the next day and no problems since.
Thank god for modern dentistry.
Did you have implants?
