About 15 years ago I had 4 silver fillings my dentist said needed to
be replaced. He replaced them with composite fillings. The dentist
didn't even ask me if I wanted composite ones, as I can recall, he
just put them in. What is the point of putting 4 composite fillings in
when every other
molar in my mouth has silver. 4 composite fillings vs the rest isn't
really cosmetic. Anyway I got rid of that dentist years ago. Actually
didn't go to another dentist for almost 15 years. Had no tooth
problems just hated going to a dentist.
Finally decided to go to a new dentist, was higly recomended by a
friend of mine. First appt.
was for cleaning and dentist cleared me, no real problems, maybe some
work in the future.
2nd and 3rd, 6 mo. checkups were the same. 4th checkup the dentist
noticed a dark spot under one of my composite fillings, and another
composite was deeply gouged out.

So an appt. was made and today I was there for the work. He said he
had to drill a little
deeper that he thought because there was decay under the composite
fillings. Also said it looked like the dentist that put in the
composite fillings didn't use a bonding agent that would bond the
teeth to the composite filling. Without the bonding agent the
composite fillings will expand and contract differently with the teeth
with cold and hot temps. causing a crack between the teeth and the
composite allowing bacteria to get under the composite and to the
tooth causing decay.
Have two other composites that need to be replaced now.
Thoughts and contradictions wanted.
Thanks, Dan.
