Q. i have had all zirconum crowns on my top teeth and 6 on the bottemas i was told this was the best option for me ,this as cost me so much money but im always in pain . when i close my mouth it feels like my jaw doesnt relax properly although my bite feels ok other than it feels like im putting pressure on the top 5 tooth along when i close my mouth ,then i start to get pain in 5th tooth it feels like it is coming from round the gum area although and then this causes the tooth next to it to hurt .my bit feels realy good took a while to get used to the teeth ,but im still getting alot of sensertivaty on the bottem 4 front teeth my teeth feel realy good other than the 5 th tooth on top which feels like im putting pressure on it when i close the teeth together .,and is it normal to get so much sensertivaty mainly in bottem,
