Ultrasonic tooth cleaner

Claim 2

An ultrasonic cleaner for removing deposits from a dorsal surface of a tongue, comprising: a handle having an ultrasonic driver; a cleaner tip coupled to and being oscillated by said ultrasonic driver, said tip having a distal end and being shaped such that said distal end is generally perpendicular to said handle, said tip being formed of a polymer material capable of transmitting constant ultrasonic vibrations from said driver; a dispersive head connected to said cleaner tip, said head extending in a plane generally perpendicular to said cleaner tip and being oscillated by said ultrasonic driver.

Claim 3

A cleaner as in claim 1, further comprising: a base connected to said handle, said base controlling said ultrasonic driver and supplying fluid flow to said handle, said handle having an axial channel for receiving said fluid, said cleaner tip and said dispersive head each having a central bore for receiving said fluid from said handle and delivering said fluid approximately at said distal end.

Claim 4

A cleaner as in claim 1 wherein said dispersive head is also formed of a polymer material capable of withstanding and transmitting constant ultrasonic vibrations from said driver.

Claim 5

A cleaner as in claim 1 wherein said dispersive head and said cleaner tip are formed from the same polymer material.

Claim 6

A cleaner as in claim 1 wherein said dispersive head and said cleaner tip are formed from different polymer materials.

Claim 7

A tooth cleaner as in claim 1 wherein said polymer material has a hardness less than that of tooth enamel.

Claim 8

An ultrasonic tooth cleaner as in claim 6, further comprising: a base connected to said handle, said base controlling said ultrasonic driver and supplying fluid flow to said handle, said handle having an axial channel for receiving said fluid, said cleaner tip having a central bore for receiving said fluid from said handle and delivering said fluid approximately at said distal end.

Claim 9

An ultrasonic tooth cleaner for removing deposits from a tooth surface, adjoining soft tissues, or both and ultrasonically providing therapeutic and other dental hygiene fluids thereto, comprising: a handle having an ultrasonic driver for creating ultrasonic vibrations and an axial channel for receiving a fluid and imparting said ultrasonic vibrations thereto; a base connected to said handle, said base energizing said ultrasonic driver and supplying said fluid to said handle; a cleaner tip removably coupled to and being oscillated by said ultrasonic driver, said tip consisting essentially of a polymer material capable of transmitting constant ultrasonic vibrations from said ultrasonic driver and having a distal end and a channel for receiving said fluid from said handle and delivering said fluid as an ultrasonically dispersed fluid spray approximately at said distal end, said tip including an bore at said distal end which is enlarged relative to said channel, said bore having a size sufficient to prevent coalescence of the ultrasonically dispersed fluid spray upon emission from said distal end.

Claim 10

An ultrasonic tooth cleaner for removing deposits from a tooth surface, adjoining soft tissues, or both and ultrasonically providing therapeutic and other dental hygiene fluids thereto, comprising: a handle having an ultrasonic driver for creating ultrasonic vibrations and an axial channel for receiving a fluid and imparting said ultrasonic vibrations thereto; a base connected to said handle, said base energizing said ultrasonic driver and supplying said fluid to said handle; a cleaner tip removably coupled to and being oscillated by said ultrasonic driver, said tip consisting essentially of a polymer material capable of transmitting constant ultrasonic vibrations from said ultrasonic driver and having a distal end and a channel for receiving said fluid from said handle and delivering said fluid as an ultrasonically dispersed fluid spray approximately at said distal end, said tip including an bore at said distal end which is enlarged relative to said channel, said bore having a size sufficient to prevent coalescence of the ultrasonically dispersed fluid spray upon emission from said distal end.

Claim 11

A tooth cleaner as in claim 8, wherein said cleaner tip is gradually curved and is formed of a composite resin.

Claim 12

A tooth cleaner as in claim 8 wherein said polymer material has a hardness less than that of tooth enamel.

Claim 13

A tooth cleaner as in claim 8, wherein said cleaner tip is elongated in an axial direction such that said distal end contacts a rearmost tooth within an oral cavity without any portion of said handle being within said oral cavity.

Claim 14

A tooth cleaner as in claim 8, further comprising a plurality of said cleaner tips interchangeably coupled to said handle.

Claim 15

A disposable cleaner tip for an ultrasonic tooth cleaner of the type having a vibrating portion and which delivers a fluid, comprising: an elongated, plastic housing having an axial channel extending from a proximal end to a distal end, said channel emitting a fluid spray delivered by said ultrasonic tooth cleaner, said proximal end being shaped to be removably coupled to said ultrasonic tooth cleaner, and said channel including a bore at said distal end which is enlarged relative to said axial channel, said bore having a size sufficient to prevent coalescence of the fluid spray upon emission from said distal end.

Claim 16

A disposable cleaner tip for an ultrasonic tooth cleaner of the type having a vibrating portion and which delivers a fluid, comprising: an elongated, plastic housing having an axial channel extending from a proximal end to a distal end, said channel emitting a fluid spray delivered by said ultrasonic tooth cleaner, said proximal end being shaped to be removably coupled to said ultrasonic tooth cleaner, and said channel including a bore at said distal end which is enlarged relative to said axial channel, said bore having a size sufficient to prevent coalescence of the fluid spray upon emission from said distal end.
