When decay has been removed from the tooth, it is replaced with “filling” material. In the past, amalgam (silver/mercury) fillings were placed into the cleaned out portion of the tooth. You may notice that silver fillings look dark; and they can also cause fractures. With advancements in dentistry, you can now have tooth-colored fillings instead of silver fillings. Tooth-colored fillings bond to the tooth, creating a seal that helps to prevent future decay. Your smile will also look wider and brighter, giving you a more youthful appearance.
