Sensitive tooth is a major problem among many dental patients and most common reason to pay a visit to one's dentist. Eating anything might cause people with tooth sensitivity a jolt of pain. In an attempt to deal with this persistent issue of the mass, the scientists from Taiwan, Mr. Chun-Pin Lin and colleagues are working on a project to develop a new biomaterial that can potentially rebuild worn enamel and reduce tooth sensitivity for an extended period. The material has been tested on dogs and a report about it has been published in the journal ACS Nano.
The sensitivity occurs when the tooth's enamel degrades, exposing tiny, porous tubes and allowing underlying nerves to become more vulnerable to hot and cold food. Current treatments available, including special toothpastes, mainly 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. Mr. Lin's team wanted to find a more durable and long-lasting way to address the condition.

They tested it by first applying the mixture to dogs' teeth and found that it plugged exposed tubes more deeply than other treatments. This depth could be the key to tackle the condition to repairing damaged enamel and providing longer-lasting relief from tooth sensitivity, according to the researchers.
