Good Neighbor Dental

Do NOT go here. I go to the dentist every 6 months and have only had 1 cavity in my life. Having recently moved to Clarksburg, I wanted to move to a closer dentist. After taking x-rays (even though I told them I had x-rays 6 months ago at my prior Rockville dentist), the dentist told me I had 9 cavities! I decided to get a second opinion. Then my insurance EOB just came in. They charged $40 in non-covered fees for "Hygiene Instruction" What is that? Is it because they told me to brush better and floss more? Every dentist has told me that. Don't go here, they just want your money and will charge you for unnecessary things!
