Q. I have an appt on 07/06 for 6 front porcelain crowns to fix small spaces in my teeth. My teeth arent really crooked my husbnd and friends say im crazy to get the work done they all recommend to do the invisalign and a whitening.The whole shaving my natural tooth away freaks me out and some reviews ive read about the pain and sensitive teeth pain after the work. and some complaints are that the tooth underneath the crown easily starts decaying! why i didnt think it would it has a crown on it…my appt is mon should i back out and can if he hasnt done any work he just did a molding of my teeth. WHAT TO DO!!!???
