cerec fillingToday, with modern technology, we can offer the patient top-quality long-lasting fillings in a matter of one hour. The ever-increasing demand for aesthetic restorations (white fillings), together with increased longevity, has led to great advances in certain dental materials like porcelain. Porcelain fillings nowadays are made mostly chair- side, while you wait. The advantage of chair-side manufactured porcelain fillings using “cad cam” technologies – like Cerec restorations – is that they have the same success rate as gold: 93 per cent after 15 years. The wear on porcelain fillings is similar to that on a tooth. On molar teeth, which sometimes require a larger filling, they are the material of choice. They are metal free and biocompatible.

They cost less but need to be replaced on average every 4 to 5 years whereas a Cerec porcelain filling can last up to 15 years and longer. On molar teeth that sometimes need a larger filling they are not particularly strong and tend to fracture after a few years.

Over the long run to the cost of placing one porcelain filling is less than placing 3 to 4 composite resin fillings in succession on the same tooth.
