Highly impressed with the new laser equipment used to remove decayed tooth material instead of drilling. Removes much less adjacent, good tooth material because the laser is much more precise (so helps forestall the need for crowns.) No Novocain needed and no pain. Mouth not aching and sore afterwards and not half dead for the rest of the day. No more expensive than the old-style drilling. In and out in 45minutes ( no waiting for Novocain to take effect). Walked out feeling just as fine as when I went in although, naturally, a bit lighter in the purse. For me, worth every bit of the 130 mile drive each way (I live in the middle of New Hampshire).
