The plant-based active in this toothpaste is oak bark extract from Quercus robur. Oak bark naturally contains tannins, plant compounds known for a slightly astringent sensation. In a toothpaste, that can contribute to a cleaner, fresher feeling in the mouth and may help the gums feel more comfortable after brushing.
This should be understood as oral care support, not as a treatment for gum disease, bleeding gums, infections, mouth ulcers, or ongoing irritation. If your gums are consistently sore, swollen, bleeding, or unusually sensitive, toothpaste alone is not the right way to assess the problem; a dentist can check whether there is plaque build-up, brushing trauma, or another cause that needs professional attention.
The formula also includes hydrated silica, which helps lift plaque from the tooth surface during brushing, plus sorbitol and glycerin, which help keep the paste smooth and pleasant to use. For best results, use a soft toothbrush and gentle pressure, because aggressive brushing can irritate gums even when the toothpaste itself is mild.
