A crown is used to strengthen a tooth, it covers the entire tooth and offers a strong support. A bridge is multiple crowns fabricated together that spans an area where a tooth is missing.
Not everyone will need a crown or a bridge. However, if you have damaged teeth or missing teeth, then these are options that can help restore the function and aesthetics of your teeth. When a tooth has a cavity or damage that’s too large for a filling, then a crown can restore function to the tooth and protect it from additional decay or damage.
If you’re missing teeth, then a bridge may restore structural stability and function to your mouth.
