Hi Tony,
Interesting info. Abrasiveness as opposed to hardness wearing down a natural tooth. Dr. states that porcelain is harder than a natural tooth. Put the both together, and you get serious wear. I noticed a lot of this on the work modes I get.
Yeah prices...depends on a lot of factors. Now, all prices will increase due to the increase in fuel costs. I hope it settles out by next summer. Price of a Big Mac, or Bubbles and Squeak will climb for a while.
Thanks for the input Tony.
Mike.
