One of the many reasons people avoid the dentist is that they're really afraid of needles.
And, seriously, who could blame them? Just the thought of getting your gums pricked--or the sight of a scary-looking syringe like the one in the photo--is enough to make you shiver.
Still, putting off cavity fillings or root canals isn't a healthy strategy for the long run. So that's why we're cheering at this latest dental breakthrough. Researchers from Brazil found that applying the numbing gel that dentists routinely use now via an electric current made the anesthetic last longer--and eliminated the use of needles altogether. Even better, it didn't hurt to get it, either.
The researchers are confident that using electric currents will be quicker, painless, and cheaper than needles. Plus, they say, it'll help people return to their dentists--and that's good news for everyone's oral hygiene.
