White composite fillings are a newer solution to restoring cavities and other dental issues. Traditional fillings use materials like gold, porcelain, and composite or silver amalgam. While their strength and durability are still useful in places like the back of your mouth, where extreme forces from chewing call for these qualities, the fillings stand out visually. Newer dental fillings use plastic and ceramic compounds that look much more like natural teeth. These compounds or composite resins work incredibly well on front teeth, where they need to look natural.
