I've had the amalgam (mercury) removed from a chipped tooth (#37). A
white-filling (plastic with light gun) was then put on the tooth. Now
the tooth's nerve is sensitive to light pressure while eating, even
though the bite has been adusted and seems fine. Is this sensitivity
normal with white fillings, and how long does it normally take to go
away? Dentist has suggested removing the white filling and replacing
it with amalgam (ugh!).

Any intelligent advice is appreciated!
Thanks!
