Restoring a tooth means repairing and reconstructing a damaged tooth with the aim of recuperating its function and its appearance. Dental fillings, crowns and bonding are the most common tooth restoration procedures. Teeth fillings are used when a decayed tooth leaves a cavity and crowns are caps used to cover and protect a damaged tooth. Dental bonding is the placement of a tooth-colored resin that is used to repair chipped, cracked or gapped teeth. These procedures are restorative and help maintain the remaining structure of the tooth, prevent further damage to the tooth and improve your overall health and the look of your smile.
