The problem
Four reasons your mouth loses its balance
Four things go wrong at once in your mouth — and a mint or mouthwash can’t fix any of them. Here’s what goes wrong, and how each one is answered.
- 01
Harmful bacterial overgrowth
Unwanted bacteria multiply on the tongue and gums and release sulphur compounds — the main source of bad breath.
Answered byK12 + M18These two Streptococcus salivarius strains settle on the tongue and teeth and crowd out the odour- and decay-causing bacteria.
- 02
Missing protective strains
Brushing and mouthwash clear bad bacteria — but also the good ones that keep your mouth in balance.
Answered byFive-strain complex7 billion good bacteria per sachet repopulate the mouth with the protective strains it is missing.
- 03
Gum irritation & bleeding
When bad bacteria dominate along the gum line, gums become sensitive and bleed when you brush.
Answered byL. reuteri + peppermintL. reuteri produces reuterin, a natural compound linked to calmer gums. Peppermint soothes and freshens.
- 04
No fuel for good bacteria
Probiotics are living bacteria — without food, they can’t multiply or hold their ground.
Answered byChicory root inulin900 mg of prebiotic fibre feeds all five strains, so they multiply within 3–4 days.

Real customer journeys
Before and after adding Oral Biotics
My breath is so much fresher. Even my partner noticed without me saying anything.
Bleeding gums are basically gone after three weeks. Very pleased.
It took about two weeks for me to notice a difference. Now my mouth feels cleaner all day.
It dissolves instantly on the tongue. And it's an easy habit to build on top of brushing.

Tina FabjanThe authority · Formulated with
Dr Tina Fabjan, BDS
Dentist, aesthetic dentistry
Dr Tina Fabjan, BDS, graduated from the Faculty of Medicine in Ljubljana in 2005. She went on to work in dental services internationally, focuses on aesthetic dentistry and today runs three dental practices.
Her day-to-day work covers aesthetic treatments such as teeth whitening, scaling and invisible braces — work that starts with a healthy mouth. For her, patient satisfaction always comes first: the goal is that every patient leaves with a brighter smile and more self-confidence.
That focus on healthy teeth and gums from the inside out is what she brought to Oral Biotics — a daily oral probiotic designed to complement brushing, flossing and regular dental check-ups, not replace them.
