Q. When my crown was put in, the dentist had to grind the top of it to fit against the opposing tooth. While doing that he also ground the side of the crown that faces my tongue – not for fit, I think he just slipped. I told him it felt rough (no anesthesia), so he grinded the whole side of the crown to smooth the scratches. It is still rough, not smooth and polished like normal teeth or the other side of the crown, which he did not grind. I find myself rubbing my tongue on it (which has actually made my tongue sore – obsessive, I know!). I am wondering if it is common practice to grind the side of the tooth and if it is possible to put some sort of enamel on it to give it a smooth surface?,
