The mineral particles may comprise, e.g., calcium phosphate, preferably, hydroxyapatite, preferably, in crystalline form. The protein matrix may comprise, e.g., a self-assembling peptide. The product also comprises a fluorophore, which may be a fluorescent amino acid residue of the protein matrix. The invention also relates to cosmetic use of the dental care product for whitening teeth or for use in treatment of a sensitive tooth or sensitive teeth and/or in prevention or treatment of caries, as well as a related method for tooth whitening.
1. A dental care product comprising 0.4-40 wt % calcium phosphate particles and 0.001-5 wt % of a self-assembled protein forming a hydrogel, wherein the particles have a size of 0.01-50 μm, wherein the self-assembled protein comprises the amino acid sequence SEQ ID NO: 1.
2. The dental care product of claim 1 , wherein said calcium phosphate particles comprise hydroxyapatite.
3. The dental care product of claim 1 , wherein the dental care product is selected from the group consisting of toothpaste, prophylactic paste, tooth powder, tooth polish, tooth gel, chewing gum, candy, lozenge, mouthwash, whitening strip, coated dental floss, coated toothbrush, paint-on gel, varnish, veneer, and tube, syringe or dental tray comprising a gel or paste.
4. The dental care product of claim 1 , comprising 0.5-40 wt % of said calcium phosphate particles and 0.02-1 wt % of said protein, wherein the dental care product is a toothpaste or gel.
5. The dental care product of claim 1 , wherein 30-70% of said calcium phosphate particles have a size of 200-600 nm.
