Tooth-Colored Fillings in Concord, NH

If you’ve ever visited the dentist to have a cavity filled, you’re among the majority of Americans. Fillings prevent further decay and damage to the gums but do typically need to be replaced after about 7-10 years. However, researchers are experimenting with a pine tree bark extract that can prolong the life of a filling and reduce trips to the dentist.

When a tooth starts showing signs of decay, a dentist in Concord, NH can drill out the deteriorated portion and fill in the holes with a tooth-colored, resin material. Over time, the bond between the resin material and the dentin - the tissue beneath the enamel - weakens, and the filling can fall out. Strengthening the dentin may be the answer to longer-lasting fillings.

How Pine Tree Bark Extract Strengthens Teeth

In a study published in the Journal of Organic Chemistry, researchers found that an extract from the bark of pine tree roots can strengthen the dentin, resulting in a longer-lasting bond between the resin and the tooth. In fact, the dentin was ten times stronger after being treated with the extract. Dr. Guido Pauli, of the University of Illinois at Chicago, estimates that the extract could extend the life of fillings for up to 10 years.

What This Means for You

More research is needed to create an extract dentists can use when treating dental caries (tooth decay). If a dentist in Concord, NH, can apply a refined extract to the tooth after drilling, the filling material could then be bonded more strongly to the tooth.
