Because they are virtually indistinguishable from natural tooth material and provide a stronger, potentially safer alternative to traditional metal fillings, Gentle Dental is committed to using tooth-colored porcelain fillings to restore teeth damaged by cavities or trauma. There are two basic types of porcelain fillings, also known as "indirect" fillings: inlays and onlays. Both types of fillings are painstakingly crafted to fit precisely in the area from which damaged tooth structure has been removed. The primary difference between inlays and onlays is that the former is crafted to fit inside an area of decay while the latter is laid atop the tooth, covering its cusps. The porcelain used in either restoration is strong enough to preserve the health of your remaining tooth while maintaining the appearance of your smile.
