Amalgam fillings are capable of lasting for several years, but ultimately will corrode and stain. As soon as this transpires, the tooth and the filling will begin to break away from each other leaving the region open to microbes that might enter the gap and bring about injury and corrosion underneath the restoration. Once this is uncovered, your amalgam restoration will need to be extracted and substituted with a porcelain filling.
One of the fantastic advantages of porcelain white tooth fillings is that they attach completely to the tooth, making them considerably stronger than silver amalgam fillings. In addition, less of the tooth has to be removed in preparation for the bonding treatment, thus preserving more of the natural tooth.
Porcelain fillings are most frequently utilized in cases where there is only a minor amount of tension on the tooth and the deterioration is mild to moderate. When the damage is too severe and there is not sufficient structure on the tooth remaining, a dental crown might be necessary to help deal with the full forces of biting and chewing.
If multiple silver fillings are present, it is optimal to swap a few silver restorations at a time rather than doing the treatment numerous times. The silver amalgam fillings are removed with a dentistry hand tool and the exteriors of the tooth are meticulously cleaned before the tooth-coloured replacement filling is placed. This porcelain filling is professionally shaped and contoured to resemble a natural tooth and to fit the bite.
