The scientists have come up an advanced gel formula which can treat tooth decay in unique way. The treatment will undertake root canal therapy for improvising diseased teeth, making them healthy and living again.

The most striking part of the treatment is that it doesn't leave the any dead tooth in the mouth. Nadia Benkirane-Jessel of Inserm, said that root canal treatments save millions of people from tooth loss every year.

The process involves the dentist in the removal of the deteriorated, dead pulp developed in the form of a cavity. The cavity develops within the soft tissue in the damaged tooth.

Regenerative endodontics is a procedure of enlargement and the improvisation of the tissues for the replacement of deteriorated or damaged dental pulp.

It is capable of serving as a striking substitute for pulp removal.

Scientists are suggesting the evolution of a multilayered, tiny film which is only 1/50,000th of the width of a human hair. It constitutes a core, which rejuvenates the dental pulp.

It's not like toothpaste. "Here we are really trying to control cavities",said Benkirane-Jessel, a scientist at the Institute National de la Sante et de la Recherche Medicale.
