Abstract

A dental cleaning implement includes a handpiece graspable at one end by a user, an electrical oscillating drive within the handpiece for oscillating the handpiece at a frequency of at least 5 Khz, a head at the opposite end of the handpiece including attaching apparatus for releasably attaching a toothpick or toothbrush thereto, and a spray nozzle for discharging a liquid spray in the region of the toothpick or toothbrush when attached to the head.

Claims

1. A dental cleaning implement, comprising:

a handpiece graspable at one end by a user;

an electrical oscillating drive within the handpiece for oscillating the handpiece at a frequency of at least 5 Khz;

a head at the opposite end of the handpiece for releasably attaching a toothpick thereto;

and a wooden toothpick removably attached to said head.

2. The dental cleaning implement according to claim 1, further including a spray nozzle at said opposite end of the handpiece for discharging a liquid spray in the region of the toothpick when attached to said head.

3. The dental cleaning implement according to claim 1, wherein said toothpick is releasably attached to said head substantially perpendicularly to the axis of said head.

4. The dental cleaning implement according to claim 3, wherein said head includes a stem formed with a transverse bore for receiving the toothpick, and a sleeve movable with respect to said stem to clamp the toothpick within the bore.

5. The dental cleaning implement according to claim 1, wherein said toothpick is releasably attached to said head substantially coaxially with respect to said head.

6. The dental cleaning implement according to claim 5, wherein said head comprises a socket formed in an end of said head for receiving one end of the toothpick with a friction fit.

7. The dental cleaning implement according to claim 1, wherein the axis of said head is at an angle to the axis of said handpiece.

8. The dental implement according to claim 1, wherein said toothpick is coated with a dental reagent.

9. The dental implement according to claim 8, wherein said dental reagent is a topical anesthetic.

10. The dental implement according to claim 8, wherein said dental reagent is an oil enhancing the removal of bacterial plaque.

11. The dental implement according to claim 8, wherein said dental reagent is a fluoride to increase the resistance of the teeth to decay.

12. The dental implement according to claim 8, wherein said dental reagent is a color-changeable pH indicator, which indicates an acidic or basic condition in the mouth of the user by using the toothpick.

13. The dental implement according to claim 8, wherein said dental reagent is an antibiotic.

14. The dental implement according to claim 8, wherein said dental reagent is an anti-inflammatory sensitivity-reducing reagent.

15. The dental implement according to claim 8, wherein said dental reagent is an anti-calculus reagent.

16. A method cleaning teeth, comprising:

grasping a dental implement including a handpiece, and an electrical oscillating drive within the handpiece for oscillating the handpiece at a frequency of at least 5 Khz, a head at an end of the handpiece for releasably attaching a wooden toothpick thereto, and a toothpick releasably attached to said head;

and applying said wooden toothpick to the space between the teeth, and also to the space between the teeth and gums, while oscillating the toothpick at a frequency of at least 5 Khz.

17. The method of claim 16, including the further step of discharging a spray of a liquid in the region of the toothpick while being used to clean the teeth.
