After decay is removed from a tooth, something must be placed in that space to give strength back to the tooth. We only use metal-free restorations as metal-based (“silver”/mercury/ amalgam) fillings weaken teeth, very often leading to cracked teeth. In addition, metal-based fillings are an esthetic compromise. White fillings are cosmetically matched to look like your natural tooth; they are stronger and safer than “silver” fillings; and they are healthier for your mouth and your body.
