Abstract

This document relates to methods and materials involved in providing a tooth, tooth component, or inorganic dental material (e.g., a human tooth, a human tooth component, or an inorganic dental material within a human's mouth) with a white appearance. For example, a whitening adhesive containing a conjugate of at least a polyamine, a polyphosphate, and one or more whitening agents (e.g., titanium dioxide, zinc oxide, and/or hydroxyapatite) can be used to provide a tooth, tooth component, or inorganic dental material with a whiter appearance.

Claims (17)

1. A whitening adhesive for coating teeth comprising polyallylamine, a polyphosphate, and a whitening agent and having the ability to interact with or bind to a tooth, a tooth component, or an inorganic dental material, wherein whitening agent of said whitening adhesive is non-covalently attached to said polyallylamine, wherein whitening agent of said whitening adhesive is non-covalently attached to said polyphosphate, and wherein whitening agent of said whitening adhesive provides teeth with a white appearance when said whitening adhesive is adhered as a coating to said tooth, said tooth component, or said inorganic dental material, wherein said polyallylamine comprises:

2. The whitening adhesive of claim 1 , wherein said polyphosphate is selected from the group consisting of sodium hexametaphosphate, sodium trimetaphosphate, sodium tripolyphosphate, and sodium pyrophosphate.

3. The whitening adhesive of claim 1 , wherein said whitening agent comprises at least one of titanium dioxide, hydroxyapatite, silicon dioxide, zinc oxide, bioactive glass, and blue fluorescent protein.

4. The whitening adhesive of claim 1 , wherein said whitening agent further comprises blue fluorescent protein.

5. A method for altering an appearance of teeth, said method comprising applying to teeth polyallylamine, a polyphosphate, and a whitening agent, to form a whitening adhesive in the form of a coating on a surface of said teeth, wherein whitening agent of said whitening adhesive is non-covalently attached to said polyallylamine, wherein whitening agent of said whitening adhesive is non-covalently attached to said polyphosphate, and wherein whitening agent of said whitening adhesive alters said appearance of said teeth, wherein said polyallylamine comprises:

6. The method of claim 5 , wherein said teeth are human teeth.

7. The method of claim 5 , wherein said method comprises altering said appearance of said teeth such that said teeth appear whiter.

8. The method of claim 5 , wherein said polyphosphate is selected from the group consisting of sodium hexametaphosphate, sodium trimetaphosphate, sodium tripolyphosphate, and sodium pyrophosphate.

9. The method of claim 5 , wherein said whitening agent comprises at least one of titanium dioxide, hydroxyapatite, silicon dioxide, zinc oxide, bioactive glass, and blue fluorescent protein.

10. The method of claim 5 , wherein said whitening agent further comprises blue fluorescent protein.

11. The method of claim 5 , wherein said applying step occurs in the presence of saliva.

12. A whitening adhesive for coating teeth comprising polyallylamine, a polyphosphate, and a whitening agent and having the ability to interact with or bind to a tooth, a tooth component, or an inorganic dental material, wherein whitening agent of said whitening adhesive is non-covalently attached to said polyallylamine, wherein whitening agent of said whitening adhesive is non-covalently attached to said polyphosphate, and wherein whitening agent of said whitening adhesive provides teeth with a white appearance when said whitening adhesive is adhered as a coating to said tooth, said tooth component, or said inorganic dental material, wherein said polyallylamine comprises from about 5 wt % to about 15 wt % of said whitening adhesive, wherein said polyphosphate comprises from about 25 wt % to about 35 wt % of said whitening adhesive, and wherein said whitening agent comprises from about 10 wt % to about 20 wt % of said whitening adhesive, wherein said polyallylamine comprises:

13. The whitening adhesive of claim 12 , wherein said polyphosphate is selected from the group consisting of sodium hexametaphosphate, sodium trimetaphosphate, sodium tripolyphosphate, and sodium pyrophosphate.

14. The whitening adhesive of claim 12 , wherein said whitening agent comprises at least one of titanium dioxide, hydroxyapatite, silicon dioxide, zinc oxide, and blue fluorescent protein.

15. The whitening adhesive of claim 12 , wherein said polyamine is PAA-D41, wherein said polyphosphate is sodium trimetaphosphate, and said whitening agent is zinc oxide.

16. The whitening adhesive of claim 12 , wherein said polyphosphate is sodium trimetaphosphate, and said whitening agent is zinc oxide.

17. A method for altering an appearance of teeth, wherein said method comprises applying to teeth a whitening adhesive in the form of a coating, wherein said whitening adhesive comprises polyallylamine, a polyphosphate, and a whitening agent and has the ability to interact with or bind to a tooth, a tooth component, or an inorganic dental material, wherein whitening agent of said whitening adhesive is non-covalently attached to said polyallylamine, wherein whitening agent of said whitening adhesive is non-covalently attached to said polyphosphate, and wherein whitening agent of said whitening adhesive provides teeth with a white appearance when said whitening adhesive is adhered to said tooth, said tooth component, or said inorganic dental material, wherein said polyallylamine comprises from about 5 wt % to about 15 wt % of said whitening adhesive, wherein said polyphosphate comprises from about 25 wt % to about 35 wt % of said whitening adhesive, and wherein said whitening agent comprises from about 10 wt % to about 20 wt % of said whitening adhesive, wherein said polyallylamine comprises:
