Recently the Agassiz Dental Group put in a crown in my bottom row. Since then I've experienced mild pain around the crown. I went back to have it looked at, they told me the problem was 2 cracked teeth in the top row and I needed 2 more crowns - at $1000.00 each. I got a second opinion and they said I may be clenching my jaw. I've tried to stop clenching and the pain has since subsided.
