Canadian scientists have created almost eternal dental fillings

The majority of the population of our planet has some or other problems with teeth. And almost all of us have seals. But seals are short-lived. They are destroyed and require replacement. However, recently, scientists have created filling material that does not require replacement throughout life.

The main cause of destruction and loss of fillings are pathogenic bacteria that multiply over time in the micro-zone between the seal and the tooth. It appears almost always and does not depend on the quality of the dentist. The new type of seals differs from the long-term antiseptic effect currently used, and their durability exceeds the service life of classic seals by several dozen times.

Antibiotics are used now when installing seals, but these antibiotics are used locally, and they do not last longer than a few weeks. The advantages of these fillings is their composition. The filling material is mixed with special antibiotic nanoparticles, which make the filling super resistant to microbes on the whole surface, and these properties do not disappear over time. Thus, the antibiotic is not only in the gap between the seal and the tooth. This provides local immunity to defeat in the field of the laying of the seals. The first experiments have already shown the effectiveness of the new material. According to one of the authors,

"Today, antibiotics are used when installing the seals, however, the validity of such compositions does not exceed a few weeks. We were able to find a combination of drugs and microscopic nanoparticles, which would contain a sufficient amount of substances that will be enough to protect teeth for many years."
