The short answer
Bifidobacterium lactis BL-04, briefly
A well-known probiotic strain (strain ID disclosed, which is good label practice) more commonly studied for immune and gut outcomes than oral ones.
BL-04's oral-specific human data is thin — its presence is more about formula breadth than a targeted oral mechanism. The strain ID disclosure is still a trust signal.

Where it appears
Label factIt's in ProDentim's formula — see the label table below for its listed role[1].
Bleeding gums, loose teeth, mouth pain, or sores that don't heal are dental symptoms, not supplement deficiencies. Get professional care first — a probiotic is for maintenance, never treatment.

Bottom line
Should Bifidobacterium lactis BL-04 influence your choice?
BL-04's oral-specific human data is thin — its presence is more about formula breadth than a targeted oral mechanism. The strain ID disclosure is still a trust signal.
Almost no human data — being upfront about that is itself a ranking criterion.
Talk to your dentist before changing your oral-care routine — especially with bleeding gums, loose teeth, or mouth pain. Supplements support; they don't replace brushing, flossing, or checkups.
