  • Method of treating a patient's teeth using fluoride releasing glass composition
    Patent number: 7323160
    Abstract: A method of treating sensitive teeth includes (1) attaching a fluoride releasing glass composition to a person's tooth, and (2) allowing fluoride to be slowly released over time in order to reduce chronic and/or acute tooth sensitivity. A preferred glass composition comprises the general empirical formula given below, expressed in approximate weight percent of the element: P: 16-24, F: 5-30, O: 20-40 and at least one of Na, K, Li, or Al in an amount up to a total of about 40 weight percent and optionally, up to about 5 weight percent of boron and/or silicon.
    Type: Grant
