What Are Dental Crowns?
Dental crowns are custom-made caps that cover damaged or weakened teeth, restoring their shape, size, strength, and appearance. Think of them as protective helmets for your teeth. Made from materials like porcelain, ceramic, metal alloys, or a combination of these, crowns are designed to look and function just like your natural teeth. They’re permanently cemented over the entire visible portion of a tooth that lies at and above the gum line, essentially becoming the tooth’s new outer surface.
When Do You Need a Dental Crown?
Several situations may require a dental crown to preserve your oral health. Large cavities that are too extensive for regular fillings often need crowns to provide adequate protection and support. Teeth that have undergone root canal treatment typically require crowns since the procedure can weaken the tooth structure. Cracked or fractured teeth, severely worn teeth from grinding, and teeth with large existing fillings that are failing are also common candidates. Additionally, crowns are used for cosmetic purposes to improve the appearance of discolored or misshapen teeth, and they serve as anchors for dental bridges.
The Crown Placement Process
Getting a dental crown typically requires two appointments spaced about two to three weeks apart. During the first visit, your dentist will examine the tooth, take X-rays, and prepare it by removing decay and reshaping it to accommodate the crown. An impression of your teeth is then made to ensure the crown fits perfectly. A temporary crown protects the prepared tooth while your permanent crown is being crafted in a dental laboratory. At the second appointment, the temporary crown is removed, and the permanent crown is carefully fitted, adjusted for proper bite and comfort, then permanently cemented into place.
Caring for Your Dental Crown
With proper care, dental crowns can last 15 to 30 years or even longer. Maintain good oral hygiene by brushing twice daily with fluoride toothpaste and flossing regularly, paying special attention to the area where the crown meets your gum line. Avoid chewing on hard objects like ice, pencils, or fingernails, and don’t use your teeth as tools to open packages. If you grind your teeth at night, consider wearing a protective nightguard. Regular dental checkups and cleanings are essential to monitor the crown’s condition and ensure the underlying tooth remains healthy. While crowns are durable, the tooth underneath can still develop decay if proper oral hygiene isn’t maintained.
