Re: Filling material and biocompatibility info.

huggins has full disclosure and walter was only given partial, because companies just don't give out that info and hal was very lucky to have obtained an agreement with them.  scientific health solutions, walter clifford, hal and my dentist were the ones who told me. 

to learn about PEX, read the DRM site or write or call the company.  i read an interview with the inventor on their site that their composite fillings can last up to 22 years. 

most dentists do not do inlays/onlays or crowns unless substantial tooth structure is gone;  they prefer composites for most fillings.  when the fillings are bigger, sadly, they prefer mercury fillings unless they have to do a crown. 

i have never had a white filling shrink and fracture a tooth, in fact mercury is much more apt to do that.  ,y dentist doesn't like them for several reasons and one is that he says they have a weak spot and can break. he prefers crowns.  

most dentists do crowns before onlays/inlays because they they feel they are stronger.  but, if i had a choice, i would try onlays/inlays before crowns on my teeth if at all possible.  often times the dentist finds himself with a tooth that he feels is too big for a composite or an inlay/onlay and has to go with a crown.

i am aware of jerome's ideas, but he is controversial and i was taught differently.  most dentists charge the same or close to the same for inlays/onlays as they do for crowns.  many dentists simply have a harder time fitting indirect composites.  i have met a couple people who had crowns for 50 years, so they do not always fail.  one thing, though, they should be replaced every 10 years is what a dentist told me.  that probably helps their lifespan.  

i am not interested in a debate.
