In what will be great news for people with sensitive teeth, scientists are developing a new biomaterial that can potentially rebuild worn enamel and reduce tooth sensitivity for an extended period.
Tooth sensitivity is one of the most common complaints among dental patients. The novel paste developed by researchers is based on the elements found in teeth, namely calcium and phosphorus. They applied the mixture to dogs’ teeth and found that it plugged exposed tubes more deeply than other treatments.
According to researchers, the depth could be the key to repairing damaged enamel and providing long-lasting relief. A hot cup of tea or cocoa can give people with sensitive teeth a jolt of pain. Not only does it cause sharp pains but can also lead to serious dental problems.
The condition occurs when a tooth’s enamel degrades, exposing tiny, porous tubes and allowing underlying nerves to become more vulnerable to hot and cold. Current treatments include special toothpastes which work by blocking the openings of the tubes but the seal they create is superficial and doesn’t stand up to the wear-and-tear of daily brushing and chewing.
The findings appeared in the journal ACS Nano.
