Had a Cerec restoration done yesterday. Looks great. Feels great. Cheaper than a crown. Better than a crown. Far less hassle than a crown (see below for more Cerec info). Experienced, skilled dentist practicing first class dentistry (dont let the untidiness put you off) at a good price (and a good guy to boot.)
good Cerec info:

p.s. I have been a patient for many years and have had him do five fillings, two
gold crowns (before Cerec, and he took the time to do a more involved impression technique), and one root canal. Highly recommend.
