Historically, dental restorations were made from amalgam mixtures of metals, such as copper, silver, or tin, with liquid mercury as a bonding agent.<\/p>\n\n\n\n<p>Although this material is durable enough to withstand the pressure of daily biting and chewing, it can also cause your teeth to appear darker. Plus, it doesn\u2019t bond with your enamel and can even harm the structure of your tooth over time. Fortunately, today most dentists use durable ceramic that can be customized to match the shade, size, and shape of your pearly white for realistic results.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Is There A Black Line at the Base of My Dental Crown?<\/h2>\n\n\n\n<p>Depending on your unique circumstances, such as having a molar that requires repair, your dentist might provide a prosthetic made from porcelain-fused-to-metal. This option typically features a metallic base covered with porcelain, combining resilience with a lifelike appearance. However, over time, the ceramic can start to wear down, especially at the base of your crown where it\u2019s thinnest, allowing the darker metallic material to shine through.<\/p>\n\n\n\n<p>Whether your restoration is outdated or was intended to have a metal base, if you\u2019re starting to see a dark line, it could mean that it\u2019s nearing the end of its lifespan.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Do I Know It\u2019s Time to Get a New Dental Crown?<\/h2>\n\n\n\n<p>These tooth-shaped caps are built to endure the ongoing pressure of daily usage, and can remain in good shape for 5 to 10+ years if cared for correctly. However, they\u2019re not invincible, and eventually wear down over time. If you notice that it feels unstable or wiggles in place, has visible chips or cracks, is discolored or has a dark line at the base, or is noticeably worn down or broken, it may be time to contact your dentist for a replacement.<\/p>\n\n\n\n<p>Your provider can examine your mouth and take X-rays to monitor the tooth under your crown and verify whether it\u2019s time for a new restoration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Meet the Author<\/h2>\n\n\n\n<p>Patients at Transforming Smiles benefit from two dentists who share decades of combined experience.
