The present invention provides compositions for the prophylaxis or treatment of dental caries, dental plaque, and periodontal infection that include lactic bacteria that are not part of the resident micriflora of the mouth, that are low acidifying, and that are capable of adhering directly to the pellicle of the teeth. Preferably, the lactic bacteria of the include one or more of Streptococcus thermophilus, Lactococcus lactis subsp. lactis, or Lactococcus lactis subsp. lactis biovar diacetylactis. The compositions are used in methods of treating or preventing dental caries, dental plaque, and periodontal infection.

A lactic bacteria strain that is exogenous to the oral microflora is selected for its ability to adhere the pellicle of the teeth and to produce a growth inhibition factor. This strain is used for the preparation of a composition intended for reducing dental plaque and for treating or preventing root caries and other diseases related to Actinomyces naeslundii in mammals.

The present invention provides an oral care composition comprising a carboxylic acid of the formula (I) wherein: R1 is H, or is a substituted or unsubstituted alkyl group; and R2 is H, OH, or NH2; for use in: (a) selectively promoting, in an oral cavity: growth, metabolic activity or colonization of bacteria that have beneficial effects on oral health, relative to growth, metabolic activity or colonization of pathogenic oral bacteria; (b) selectively promoting, in an oral cavity, biofilm formation by bacteria that have beneficial effects on oral health, relative to biofilm formation by pathogenic oral bacteria; or (c) maintaining and / or re-establishing a healthy oral microflora.

The invention relates to a gum base composition for protecting the balance of oral flora. The gum-based composition is prepared from a gum base, bioactivity mineral powder and polylysine, wherein a weight proportion of the bioactivity mineral powder and the polylysine is (2 to 25) : (0.0003 to 10). According to the gum base composition disclosed by the invention, the bioactivity mineral powder and the polylysine in the gum base composition are capable of inhibiting and killing various pathogenic bacteria in an oral cavity, preventing and treating oral problems of oral infection, oral ulcer, chronic gingisitis and the like, and have long-acting bacteria resistance; meanwhile, the bioactivity mineral powder and the polylysine have a certain selective protection function on beneficial bacteria in the oral cavity, the balance of flora in the oral cavity can be effectively regulated, and normal sanitation and health of the oral cavity can be maintained. Through remineralization of the bioactivity mineral powder on teeth, the gum base composition is capable of effectively repairing dentin defects; the gum base composition provided by the invention is convenient to use, wide in receiver groups and very strong in market application value.
