## Abstract

A compound and method of treating gingival and periodontal tissues, the essential ingredient of said compound comprising potassium nitrate, and the method comprising the application of said compound in aqueous solution or nontoxic paste form to said tissue.

## Claims

### Claim 1

The method of reducing gingival bleeding and improving the texture and consistency of gingival and periodontal tissues by applying thereto a composition comprising about 1-23% by weight of potassium nitrate.

### Claim 2 (depends on 1)

The method of claim 1 further characterized in that said composition comprises potassium nitrate in an aqueous solution.

### Claim 3 (depends on 2)

The method of claim 2 further characterized in that said potassium nitrate comprises between approximately five percent (5%) by weight and saturation of said aqueous solution.

### Claim 4 (depends on 1)

The method of claim 1 further characterized in that said composition comprises potassium nitrate mixed with a nontoxic paste.

### Claim 5 (depends on 4)

The method of claim 4 further characterized in that said potassium nitrate comprises approximately five percent (5%) by weight of said paste.

### Claim 6

The method of reducing gingival bleeding and improving the texture and consistency of gingival and periodontal tissues by applying thereto an aqueous solution, the essential ingredient of which is potassium nitrate, said potassium nitrate comprising between one percent (1%) by weight and saturation (approximately 20%) of said aqueous solution.

### Claim 7

The method of reducing gingival bleeding and improving the texture and consistency of gingival and periodontal tissues by applying thereto a nontoxic paste, the essential ingredient of which is potassium nitrate, said potassium nitrate comprising between one percent (1%) and saturation (approximately 23%) of said paste.
