Abstract

An apparatus for treating a tooth or gum tissue is disclosed. The apparatus can include a tooth cap for supporting a treatment device during a treatment procedure. The tooth cap can comprise a platform to support the treatment device. The platform can include an access port to provide a portion of the treatment device with access to a treatment region of the tooth or gum tissue. The tooth cap can also include a wall coupled with and angled relative to the platform, the wall configured to be attached to the tooth or gum tissue during treatment.

First claim

What is claimed is:

1 . An apparatus for treating a tooth, the apparatus comprising:
a tooth cap having a wall configured to be attached to the tooth such that a space is defined by the tooth cap and the tooth, the tooth cap including a support surface to support a portion of the apparatus, the tooth cap comprising an access port to provide the portion of the apparatus with access to a treatment region of the tooth within said space; and a treatment device comprising a pressure wave generator in communication with a chamber of a tooth coupler, the tooth coupler to be positioned against the support surface such that the chamber of the tooth coupler is in fluid communication with the access port and external to the tooth cap, the pressure wave generator positioned entirely within the tooth coupler and configured to generate pressure waves in the tooth coupler that propagate through the access port, through the space in the tooth cap, and to said tooth, the pressure wave generator configured to be in fluid communication with said tooth.

2 . The apparatus of claim 1 , wherein the wall of the tooth cap is adapted to extend at least partially along a height of the tooth such that a distal end of the wall is positioned between an occlusal surface and gums for treating a decay on the occlusal surface and/or on one or more side surfaces of the tooth and/or one or more interior regions of the tooth via an endodontic access opening.

3 . The apparatus of claim 2 , wherein the wall of the tooth cap is adapted to extend along the height of the tooth such that a distal end of the wall is positioned adjacent the gums for treating the decay on the occlusal surface and/or on the one or more side surfaces of the tooth and/or the one or more interior regions of the tooth via the endodontic access opening.

4 . The apparatus of claim 1 , wherein the tooth cap is adapted to be disposed on a side surface of the tooth for enclosing a portion of the tooth including a decay on the side surface of the tooth to be treated.

5 . The apparatus of claim 1 , wherein the space of the tooth cap is adapted to be filled with treatment fluid.

6 . The apparatus of claim 1 , wherein the support surface is angled inwardly relative to the wall.

7 . The apparatus of claim 1 , wherein the wall has a rigid portion and a flexible portion adjacent to the rigid portion.
