Question:
Restorative materials for dentin: The enamel has come off the back of my upper two front teeth as a result of acid erosion which occurred many years ago.
I did have some restoration awhile back which held for 7 years. However those finally came off and it appears that there is only dentin left.
I am not certain if there was enamel on those restored areas and if that is what the restorative material was applied to or if it was applied directly to dentin 7 years ago. I think if was dentin because the surface looks just like it did before the restoration that was done 7 years ago.
Are there restorative materials that have been developed that adhere to dentin better than it did 7 years ago? ...Visitor in TX
Answer:
Most cements will adhere to dentin.
A glass ionomer cement called Rely-X should adhere to dentin. The teeth should be able to be restored with an all-white material (Procera, E-Max) that does not need to be bonded to enamel, but cemented to dentin.
If the last restoration lasted for 7 years, that's pretty good and I assume the newer materials will last longer.
