Abstract

The present invention automated dental cleaner includes a housing and a pair of spaced tines supported on the housing. The tines hold a length of dental floss therebetween to form a span of floss. A bracing fork having a pair of bracing tines for straddling teeth braces the dental cleaner against the teeth, thereby allowing the floss to be reciprocated by a motorized drive.

Claims

1. A dental cleaner comprising:

a fork having a pair of tines for receiving teeth to be cleaned therebetween;

first and second brushes, each brush being attached to a respective tine and having bristles extending inward between the tines for engaging lingual and buccal tooth surfaces simultaneously;

a third brush attached to the fork and having bristles extending medially thereof for engaging tooth top surfaces; and

a drive mechanism for reciprocating each of the first, second and third brushes in a back-and-forth linear motion.

2. The dental cleaner as defined in claim 1, wherein the fork is detachably removable from the drive.

3. The dental cleaner of claim 1, further comprising a pair of flossing tines for supporting therebetween a span of dental floss substantially perpendicular to the longitudinal axis of the drive.

4. The dental cleaner of claim 3, further comprising a limiting system for limiting the motion of the flossing tines in response to resistance encountered in use.

5. A dental cleaner comprising:

a fork having a pair of tines for receiving teeth to be cleaned therebetween;

first and second brushes, each brush being attached to a respective tine and each brush having bristles extending inward between the tines for simultaneously engaging lingual and buccal tooth surfaces; and

a drive for reciprocating the first and second brushes in a back-and-forth linear motion.

6. The dental cleaner as defined in claim 5, further comprising a third brush attached to the fork and having bristles extending medially thereof for engaging tooth top surfaces, the third brush being connected to the drive for being reciprocated.

7. The dental cleaner as defined in claim 5, further comprising a pair of flossing tines for supporting therebetween a span of dental floss substantially perpendicular to the longitudinal axis of the drive.

8. The dental cleaner as defined in claim 7, further comprising a limiting system for limiting the motion of the flossing tines in response to resistance encountered in use.

9. A dental cleaner comprising:

a housing;

a fork supported on the housing having a pair of spaced tines for receiving teeth to be cleaned therebetween;

first and second brushes attached to the tines, respectively, the brushes having bristles extending inward between the tines for simultaneously engaging lingual and buccal tooth surfaces, thereby bracing the fork against the teeth; and

a drive for driving the dental cleaner and inducing a cleaning motion to the bristles, the drive including a cam for moving the brushes in a forward linear motion, and a spring for biasing the brushes back in a rearward linear motion.

10. The dental cleaner as defined in claim 9, wherein the bristles are of differing lengths.

11. The dental cleaner of claim 9, further comprising a pair of flossing tines for supporting therebetween a span of dental floss substantially perpendicular to the longitudinal axis of the drive.

12. The dental cleaner of claims 11, further comprising a limiting system for limiting the motion of the flossing tines in response to resistance encountered in use.
