I needed two onlays replaced (that were chipped/cracked), which were made by a previous dentist. Dr. Lewock prepped the teeth for two crowns and from the start I couldn't even feel the novocain injection. He thoroughly explained the details as he proceeded, and afterwards and a day later, I experienced no pain or hot/cold sensitivity. With crowns, he always does a meticulous job with tooth anatomy and fitting. I don't think you could find a better dentist. – Ed L.
