Didn't take a proactive, preventative approach to dentistry. Example - I've been going to Dr Carson's office for 4 years and recently I was told my back molars needed to be crowned because I was grinding my teeth while I was sleeping and had ground all of the enamel off. Then they suggested I buy a $600 night guard to protect my teeth at night. But I couldn't understand why they had waited until my molars had no more enamel on them to suggest a night guard!! They should have been able to see the problem developing for years!! And what's the point of getting a night guard AFTER the damage has been done and two teeth need to be crowned!!
