After visiting Dr Bass for simple routine dentistry for a few years, I recently had extensive work done on 6 of my right upper and lower molars. Most of this work was optional in nature as I wanted to replace mercury fillings. Immediately, after all of this work was done costing me thousands of $, two of the teeth he worked on were causing me agonizing pain. Now I need 2 root canals and 2 crowns. Another $4,000. I am going to a different dentist for this work, and expect better results.
