this dentist performed a root canal and gave me a 'free' upgrade crown which holds a 5 year warranty, The crown failed in 2 years and he won't honor the warranty because I didn't pay for the upgrade. His failed work cost me over $900.00 after I paid him $1,200.00 2 years ago. He was intimidating and scared me as he said he has big burly hockey players that are big babies in his chair so he just gives it to them a little harder...but he said he wouldn't hurt me. This was being said while in the middle of a root canal!! He said my tooth will now need to be pulled and an implant or bridge will need to be in it's place. My current dentist restored the tooth, installed a post with a crown. Didn't need to pull the tooth. I just want to be compensated for the cost to restore. He wont do it.
