At our clinic we use a root filling material called N2. 

​

 

 

N2 is bactericidal with an effect that lasts for one week and then becomes neutral. This material therefore has properties that beat many other materials on the market. If you would like to read more, visit this website: www.rotfyllning.nu

Many patients have experienced that previously root treated teeth become infected again. If, in such a situation, the patient need a crown on the tooth, it can be very difficult to re-do the root filling and the result may be that the tooth have to be removed. By dentist Bengt Nordströms experience, with the material N2 in such cases, he has had a success rate of almost 100%.
