Getting a filling is often the best way to restore a tooth back to its normal function and shape. Several materials can be used as fillings such as gold, porcelain, and composite resin.
A dental crown is necessary when a tooth has substantial decay and needs an extra layer of protection that a filling cannot offer. a crown is a custom fabricated tooth that is placed over the existing tooth to restore its shape, size, and appearance.
A bridge can vary in function or design, but is most often used to restore a missing tooth or multiple missing teeth. Dental bridges can be supported by either natural teeth or dental implants. That can be made of either gold, porcelain, or zirconium.
