Abstract
A dental composition, and methods of use thereof, for causing tooth whitening and/or tooth mineralization without causing tooth hypersentivity. The dental composition contains a gel-forming thickening agent and nitrogen-doped titanium dioxide nanoparticles. The nitrogen-doped titanium dioxide nanoparticles may be co-doped with fluorine and/or silver. The dental composition may contain a bleaching agent.
Claims23
A dental bleaching composition, comprising a peroxide bleaching agent, a gel-forming thickening agent, and nitrogen-doped titanium dioxide nanoparticles, and the dental bleaching composition causing an increase in mineralization of the teeth to which it is applied without causing dentin hypersensitivity of the teeth.
A method of whitening teeth, comprising applying to a subject's teeth a dental composition comprising a peroxide bleaching agent, a gel-forming thickening agent, and nitrogen-doped titanium dioxide nanoparticles, wherein the dental composition causes an increase in mineralization of the teeth to which it is applied without causing dentin hypersensitivity of the teeth.
A method of enhancing mineralization in a subject's teeth, comprising applying to the subject's teeth a dental composition comprising a gel-forming thickening agent and nitrogen-doped titanium dioxide nanoparticles, wherein the dental composition causes an increase in mineralization of the teeth to which it is applied without causing dentin hypersensitivity of the teeth.
