Q. I have crowns on 3 of my front top teeth and a tooth bridged off to my left where I was missing a front tooth, family genes, anyways it looks very unnatural, plus metal is showing at the tops of my 3 crowns. they are approx. 33 years old. I am 59. I also have other problems. Top and bottom. Missing teeth. I have only 9 teeth at top, no back teeth and bottom I have 10 with 1 molar on each side bottom. I was told I can’t have implants at the top because of my sinuses. One cosmetic dentist suggested crowing all my top teeth, removing old crowns which have the metal showing and replacing them and crowning all my top teeth with a permanent bridge off on each side at the top. I got another opinion and was told this would not hold up without an implant on the other side of each bridge, that this would cause the crowned tooth that the bridge was off to eventually crack and break. My question is what do you suggest. (I want a healthy and pretty set of teeth) and what can I do about the missing front tooth. my family calls them “little doggie teeth” Also what is the difference in noble metal on procelain and noble high metal on orcelain? Like I said I have other problems but for now if you can address this if you understand my explanation. Thank you
