Narrator: This is Science Today. The insistent, and sometimes downright ominous whine of the dental drill may soon be a thing of the past. And while you may have heard about recently approved lasers doing the job, Roy Eversole, a professor at UCLA's School of Dentistry says there's another instrument which has even more potential.
Eversole: This new device is really not only a laser, it's a laser power source, but it causes an interaction with vaporized water. The laser energy actually causes the water to explode into little micro droplets with such force that we believe that that's what's actually cutting the tooth structure away. 0:17
Narrator: This device, called a hydro-kinetic system, is virtually painless, doesn't heat up the teeth and may have better adhesion for fillings than all other techniques. But those are not the only benefits.
Eversole: If you think of the times you had your teeth drilled on, you sometimes think your brain's wobbling in your head because of all the vibrations that go all the way up into your jaws and into your skull - you get none of that effect at all with this instrument. 0:12
