Crown
A crown is a type of dental restoration which completely caps or encircles the tooth or a dental implant. Crowns are often needed when a large cavity threatens the ongoing health of the tooth. They are typically bonded to the tooth using the dental cement. Typically, implants, root canal treated teeth, badly broken teeth and improvement of esthetics are the most common reasons for placing the crowns.

Bridges
A bridge is a fixed dental restoration (a fixed dental prosthesis) used to replace a missing tooth (or several teeth) by joining an artificial tooth permanently to the adjacent teeth or dental implants. A bridge is fabricated by slightly reducing the surface of teeth on either side of the missing tooth and using them as a support to replace a missing tooth. As with crowns, bridges are also cemented with a special dental cement and are a fixed replacement.

How long do crowns and bridges last?

While crowns and bridges can endure forever, they do sometimes come loose or fall out. The most vital step you can take to guarantee the lifespan of your crown or bridge is to practice good oral hygiene. A bridge can lose its support if the teeth or bone holding it in place are harmed by dental disease. Keep your gums and teeth healthy by brushing with fluoride toothpaste two times every day and flossing daily. Likewise see your dentist and hygienist frequently for checkups and professional cleanings.

To prevent harm to your new crown or bridge, abstain from chewing hard foods, ice or other hard objects.
