Fillings are the most common type of dental restoration for cavities, cracked or broken teeth. Teeth can become worn down due to nail-biting or grinding. Fillings may also be used if there is gum recession or abrasion resulting in the loss of tooth structure, most often from your toothbrush.
Once the decayed portion of the tooth is removed, it can be filled with gold, silver amalgam, or tooth-colored plastic and glass materials called composite resin fillings The fillings are placed directly in a hole in a tooth, carved to resemble the original shape of the tooth. The filling is then allowed to harden inside the hole to restore the form and function of the tooth as well as relieve the pain associated with the cavity.
Indirect fillings made in a laboratory are known as inlays and onlays. With proper care they are more durable than direct fillings. They are also more aesthetically pleasing because they are built by a laboratory technician on a lab bench without the difficulties by the time constraint and the access we have while working in your mouth.
