Fillings replace missing tooth structure after tooth decay has been removed or if an old filling needs to be replaced after it has started to break down.
White or composite fillings are commonly placed in dentistry today due to the cosmetic advantage of being white but also due to the fact that composites can help ‘bond’ a tooth together.
Silver fillings are still used in dentistry and are a proven safe method by the Canadian and American Dental Associations for restoring teeth.
