A preform intended for the production of a dental prosthesis. The preform includes a group of agglomerated ceramic, glass-ceramic or glass particles, such that, as volume percents: more than 40% and less than 90% of the particles of said group have a size greater than 0.5 μm and less than 3.5 μm, said particles hereinafter being denoted “enamel particles”, and more than 10% and less than 60% of the particles of said group have a size greater than 3.5 μm and less than 5.5 μm, said particles hereinafter being denoted “dentine particles.” The microstructure of the preform is such that there is an axis X, termed “axis of variation”, along which the Ve/(Ve+Vd) ratio changes continuously, Ve and Vd denoting the volume percents of enamel particles and of dentine particles, respectively. The enamel and dentine particles representing, together, more than 90% of the volume of the agglomerated particles.

The present disclosure provides glass compositions that include from 45 mol% to about 95 mol% of B203; from about 3 mol% to about 60 m ol% of one or more glass components selected from the group consisting of: K20, Na20, CaO, and MgO; and from about 2 mol% to about 45 mol% of CaF.sub.2, SnF.sub.2, NaF, KF, Na.sub.2PO.sub.3 F, or a combination thereof, where the glass includes less than 30 mol% of CaF.sub.2, SnF.sub.2, or a combination thereof. The glass includes: substantially no CuO; less than 0.1 mol% of Li.sub.20, less than 0.1 mol% of Rb.sub.2O, less than 0.1 mol% of BaO; less than 0.1 mol% of P.sub.20.sub.5; less than 0.1 mol% SiO.sub.2; and less than 30 mol% of MgO. The glass composition may be used to desensitize dentin. The present disclosure also provides dentin-desensitizing compositions, as well as methods and uses of the disclosed glass compositions.
