The present invention provides new dental care products comprising self-assembling peptides that are capable of undergoing self-assembly at a certain pH for use in dental care, e.g. preventing and/or treating a tooth lesion such as a caries lesion, remineralising a tooth surface or increasing smoothness or shine, or for increasing hardness of a tooth surface. The present invention provides dental care products such as chewing gum, toffees or toothpaste, in which the peptides are present in monomeric form for a prolonged period after application into the oral cavity, thereby enabling non-targeted treatment of a plurality of teeth, independent of the diagnosis of an active lesion. Products of the invention are useful for animals and humans.
