Re: sensitivity from composites/crows

According to most dentists ,most fractures are caused by amalgam.It expands and contracts like a mercury thermometer. Dentists try to sell you crowns once they have fractured your teeth with their merrcury teeth thermometers,telling you the crown will hold the fractured tooth together although there is no evidence of this according to "Tooth Truth" by Frank Jerome and others. Most teeth will die within several years of being crowned if they dont die that day.
I was told I needed several crowns. I had one . That tooth died. The others dont bother me. Get an onlay or inlay instead.The tooth will last the longest when the maximum amount of tooth structure is preserved.
