See Why Crowns and Bridges Are So Popular
Dental crowns are needed when more than 50 percent of the tooth has been damaged, either to decay or it’s broken, or there’s a crack in the tooth. Putting a crown on a tooth restores its original strength, and it also protects the nerve inside the tooth. Dental crowns and bridges are cemented onto the teeth, so they’re not removable. You don’t have to take them out. They’re easy to maintain or actually a little easier to maintain your own teeth, so you floss them and you brush them normally.
They feel like your own teeth as opposed to something that’s removable that you would have to take in and out of your mouth, like a partial denture or a complete denture. If you’re looking to protect your tooth, especially if it’s had a lot of decay or a lot of work on it, a crown covers and protects the tooth and returns to its original function.
