Abstract

An oral insert includes a plurality of bristles and a plurality of fluid nozzles. The plurality of bristles is located on an upper portion and a lower portion of a tray surface of the oral insert. The plurality of fluid nozzles is located at an inner portion and an outer portion of the tray surface. Fluid output by the plurality of fluid nozzles causes the plurality of bristles to contact surfaces of teeth associated with a user of the oral insert.

Claims (26)

1. An oral insert, comprising:

a base that includes a plurality of manifold holes arranged in a circle;

a plurality of bristles located on an upper portion and a lower portion of a tray surface of the oral insert;

a plurality of fluid nozzles located at an inner portion and an outer portion of the tray surface; and

a plurality of manifolds, wherein each of the plurality of manifolds is associated with a corresponding manifold hole of the plurality of manifold holes, wherein each manifold of the plurality of manifolds is associated with a corresponding subset of the plurality of fluid nozzles, wherein fluid is provided to the plurality of manifolds in a particular sequence that causes the oral insert to vibrate, wherein the vibration of the oral insert caused by fluid being provided to the plurality of manifolds in the particular sequence causes the plurality of bristles to contact surfaces of teeth associated with a user of the oral insert, wherein the particular sequence causes the fluid to be alternately provided between a left side and a right side of the oral insert, wherein the oral insert is configured to be connected to a handle, wherein the fluid is provided from the handle to the oral insert via the plurality of manifold holes, wherein the handle includes a manifold disc and a manifold disc selector, wherein the manifold disc selector includes an opening and a cut-out that is opposite the opening, wherein the cut-out extends only partially through the manifold disc selector, wherein the fluid is selectively provided to the plurality of manifolds via the plurality of manifold holes as the manifold disc selector rotates.

2. The oral insert of claim 1 , wherein the plurality of fluid nozzles located at the inner portion of the tray surface are configured to output the fluid to interior surfaces of the user's teeth.

3. The oral insert of claim 1 , wherein the plurality of fluid nozzles located at the outer portion of the tray surface are configured to output the fluid to exterior surfaces of the user's teeth.

4. The oral insert of claim 1 , wherein the plurality of fluid nozzles are configured to be directed towards interproximal spaces associated with the user's teeth.

5. The oral insert of claim 1 , wherein a material of the plurality of bristles is nylon or silicon.

6. The oral insert of claim 1 , wherein the plurality of bristles are cilia-shaped bristles.

7. The oral insert of claim 1 , wherein the plurality of bristles located on the upper portion and the lower portion of the tray surface of the oral insert are arranged in a plurality of rows.

8. The oral insert of claim 7 , wherein the plurality of bristles arranged in the plurality of rows located on a bottom surface of the upper portion of the tray surface of the oral insert are configured to contact an exterior tooth surface, a bottom tooth surface, and an interior tooth surface of teeth associated with an upper jaw of the user.

9. The oral insert of claim 7 , wherein the plurality of bristles arranged in the plurality of rows located on a top surface of the lower portion of the tray surface of the oral insert are configured to contact an exterior tooth surface, a top tooth surface, and an interior tooth surface of teeth associated with a lower jaw of the user.

10. The oral insert of claim 7 , wherein a first bristle located in a first row of the plurality of rows is taller than a second bristle located in an intermediate row of the plurality of rows.

11. The oral insert of claim 10 , wherein a third bristle located in a last row of the plurality of rows is taller than the second bristle located in the intermediate row of the plurality of rows.

12. The oral insert of claim 1 , wherein a vibration of the oral insert causes the plurality of bristles to contact the surfaces of teeth associated with the user of the oral insert.

13. An oral insert, comprising:

a base that includes a plurality of manifold holes arranged in a circle;

a plurality of bristles located on an upper portion and a lower portion of a tray surface of the oral insert;

a plurality of fluid nozzles located at an inner portion and an outer portion of the tray surface; and

a plurality of manifolds, wherein each of the plurality of manifolds is associated with a corresponding manifold hole of the plurality of manifold holes, wherein each manifold of the plurality of manifolds is associated with a corresponding subset of the plurality of fluid nozzles, wherein fluid is provided to the plurality of manifolds in a particular sequence that causes the oral insert to vibrate, wherein the vibration of the oral insert caused by fluid being provided to the plurality of manifolds in the particular sequence causes the plurality of bristles to contact surfaces of teeth associated with a user of the oral insert, wherein the particular sequence causes the fluid to be successively provided to a left side and a right side of the oral insert, wherein the oral insert is configured to be connected to a handle, wherein the fluid is provided from the handle to the oral insert via the plurality of manifold holes, wherein the handle includes a manifold disc and a manifold disc selector, wherein the manifold disc selector includes an opening and a cut-out that is opposite the opening, wherein the cut-out extends only partially through the manifold disc selector, wherein the fluid is selectively provided to the plurality of manifolds via the plurality of manifold holes as the manifold disc selector rotates.

14. The oral insert of claim 1 , wherein the base is configured to be inserted into a mouthpiece seal associated with the handle.

15. The oral insert of claim 14 , wherein the handle is coupled to an oral health device base, the oral health device base is coupled to a fluid reservoir, wherein the fluid outputted by the plurality of fluid nozzles is provided from the fluid reservoir to the plurality of fluid nozzles via the handle and the plurality of manifolds.

16. The oral insert of claim 13 , wherein the plurality of bristles located on the upper portion and the lower portion of the tray surface of the oral insert are arranged in a plurality of rows.

17. The oral insert of claim 16 , wherein the plurality of bristles arranged in the plurality of rows located on a bottom surface of the upper portion of the tray surface of the oral insert are configured to contact an exterior tooth surface, a bottom tooth surface, and an interior tooth surface of teeth associated with an upper jaw of the user.

18. The oral insert of claim 16 , wherein the plurality of bristles arranged in the plurality of rows located on a top surface of the lower portion of the tray surface of the oral insert are configured to contact an exterior tooth surface, a top tooth surface, and an interior tooth surface of teeth associated with a lower jaw of the user.
