It&#8217;s held up well even though I grind my teeth at night and rarely wear my night guard. I&#8217;m not bragging about going without my night guard \u2013 my former dentist&#8217;s work is impressive. Even my current dentist in CT admitted it. In mid-April, I had some dental work completed. I couldn&#8217;t delay getting two crowns.<\/p>\n<p>In the process of trying to adjust my bite with the new crowns, my current dentist reduced the Maryland bridge tooth. A few days later when I was looking at my teeth in the mirror, I noticed a silver dot showing through that same tooth. I scheduled an appointment for my dentist to look at the tooth, and he said the metal is finally showing through because I don&#8217;t wear a nightguard. He covered the dot with composite filling, but the metal is showing again. Could the metal suddenly show through the Maryland bridge tooth, although I didn&#8217;t have any problems before? Thank you &#8211; Tamar<\/p>\n<p>Tamar,<\/p>\n<p>Your dentist doesn\u2019t want to admit that grinding down the tooth in your Maryland bridge caused the metal to show through. If he admits it, he\u2019s obligated to replace your bridge. It is possible that after he thinned the bridge that your teeth-grinding habit exposed more of the metal. But the evidence suggests that the problem occurred after your dentist adjusted your bite.<\/p>\n<h2>When Your Dentist Grinds Your Crown Down to the Metal<\/h2>\n<p><strong>Get a second opinion<\/strong> \u2013 Many dentists will give you a second opinion at no charge. How will a second opinion help?<\/p>\n<ul>\n<li>Ask the dentist if there are signs of grinding on the porcelain where the metal is showing. A dental bur leaves distinct marks on porcelain, and it will be easy for the <a href=\"https:\/\/www.drszarek.com\/cosmetic-dentist\/\">second-opinion dentist<\/a> to see the marks.<\/li>\n<li>Return to your dentist with the report form the second-opinion dentist. But don\u2019t accuse your dentist of intentionally grinding down the porcelain. It\u2019s a mistake that many dentists have made in the past.<\/li>\n<\/ul>\n<p>Below is a photograph of three crowns on back molar teeth. The porcelain was adjusted so much that the metal shows through.<\/p>\n<div id=\"attachment_1185\" style=\"width: 460px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-1185\" class=\"size-full wp-image-1185\" src=\"https:\/\/www.drszarek.com\/blog\/wp-content\/uploads\/2020\/05\/cosmetic-dentist-maryland-bridge-lowell-ma.jpg\" alt=\"Lower molar teeth with metal showing through the crowns\" width=\"450\" height=\"277\" srcset=\"https:\/\/www.drszarek.com\/blog\/wp-content\/uploads\/2020\/05\/cosmetic-dentist-maryland-bridge-lowell-ma.jpg 450w, https:\/\/www.drszarek.com\/blog\/wp-content\/uploads\/2020\/05\/cosmetic-dentist-maryland-bridge-lowell-ma-300x185.jpg 300w\" sizes=\"(max-width: 450px) 100vw, 450px\" \/><p id=\"caption-attachment-1185\" class=\"wp-caption-text\">An advanced cosmetic dentist can try to conceal metal showing through a crown or replace the crowns<\/p><\/div>\n<h2>Will You Need a New Maryland Bridge?<\/h2>\n<p>Your dentist bonded composite over the metal, but you didn\u2019t mention if he prepared the surface of the metal first.
