One came loose and fell off. I had it &#8220;cemented&#8221; back on at the dentist &#038; she ground down the porcelain to correct the bite after it was placed. Less than a week later the back side of my crown broke off where the bite adjustment had been made. What do you suggest? Should porcelain crowns ever be ground on or does this weaken them?<br \/>\n&#8211; Cheri from Minnesota<\/p>\n<p>Cheri,<br \/>\nWhen you get a new porcelain crown, it isn&#8217;t uncommon for the dentist to have to adjust the crown to your bite, which is done by grinding on it some.<br \/>\nHaving said that, something isn&#8217;t right about your experience here. Here are the three things that trouble me:<\/p>\n<p>&bull; First of all, one of the crowns came loose. This isn&#8217;t something that should be happening to a permanently cemented crown. Something wasn&#8217;t done right for a new crown to be falling off that soon.<br \/>\n&bull; Second, the bite should have been adjusted when the crown was first placed. This is strange that the bite has to be adjusted after it is recemented. Something went wrong in the recementation process. The recemented crown must not have gotten back on straight for it to require new adjustments.<br \/>\n&bull; And third, of course, you had the back of the crown break off. This wouldn&#8217;t happen unless the porcelain was ground so much as to be dangerously thin.<\/p>\n<p>The fix is to have this crown replaced. But I would go somewhere else for this. I have real concerns about your current dentist being able to get this right. Oh, and she should compensate you for having to do this.<\/p>\n<p>&#8211; Dr. Hall<\/p>\n<p>For information on why crowns fall off, please see my earlier post, &#8220;<a href=\"https:\/\/www.mynewsmile.com\/blog\/the-main-reason-your-crown-probably-fell-off\/\" target=\"_blank\">The main reason your crown probably fell off<\/a>.&#8221;<\/p>\n<p>Do you have a comment or a question or anything else to add?
