Is It Possible To Get A Cavity Inside A Crown?

Dental crowns are, by far, the best way to replace lost or damaged teeth. It offers supreme restorative strength and unmatched elegance to complete your beautiful smile. Every crown is delicately mold, designed, and customized to replace the missing tooth entirely. More than a third of the population in the US relies on dental crowns for their restorative needs. 

They say routine dental check-ups and homecare are mandatory to ensure the longevity of your crowns. But can you guarantee that getting a new replacement for your once lost/damaged tooth would mean they would remain cavity-free for life? Hold that thought there.

Would your all-new shiny or ceramic dental crown get affected by cavities? No, that's because they are made out of synthetic material that won't wear away. However, the chances are high that you may get a cavity inside the restored tooth that supports your crown. If that's the case, you'll require treatment.

Cavities and Crowns

While getting dental crowns, the procedure goes by where the dentist would remove decayed parts of the tooth and the presence of any cavities. A portion of the gums would be cut and removed from around the entire tooth to make space so that the customized crown can fit in to appear as a normal-shaped tooth.

How would decay enter underneath the crown?

The presence of decay underneath a crown is the result of dental plaque. Dental plaques are biofilms of food debris and bacteria. It is generally found at the gum line. The junction at which the tooth and crown meet is known as the margin. This margin could be susceptible to plaque and bacterial growth if oral hygiene isn't adequately maintained. The result is the development of new cavities underneath the crown. If a cavity is detected under a crown, it would have to be removed immediately.

Tips to Maintain Your Crown

Your custom-made dental crowns are made from materials that last. They are prone to wear and would be able to stand the test of time. However, as dental professionals, we also recommend that you take good care of your new restorations as much as possible while at home. Regular brushing and flossing are mandatory to keep your crowns running. Both are meant to keep away plaque and harmful bacteria at bay. This helps reduce the chances of decay formation.

While at the dentist's office, we perform professional dental cleanings with special tools that can help remove debris and other harmful elements from the oral cavity and restorations. Your regular dental check-up is vital for a proper functioning set of restorations. Dental examinations would allow the dentist to keep a check on the margins of all restorations that the oral cavity holds.
