Taipei, Jan 8 (IANS) There is a good news for people with sensitive teeth as 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,” said Chun-Pin Lin from National Taiwan University.
The researchers made a novel paste 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.
This depth could be the key to repairing damaged enamel and providing longer-lasting relief from tooth sensitivity, the researchers pointed out.
Rather than soothe and comfort, a hot cup of tea or cocoa can cause people with sensitive teeth a jolt of pain.
Not only does it cause sharp pains, but it can also lead to more 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, including special toothpastes, 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.
