All Bioniq Toothpastes have a mild formula and are generally very well tolerated. In some homeopathic treatments/therapies, flavorings in food/dental care products (such as menthol) should generally be avoided. Bioniq Toothpastes, like most toothpastes on the market, contain an aroma containing menthol, which provides a pleasant feeling of freshness. If you have any questions as to whether menthol or any of the other ingredients should be avoided during homeopathic treatment, please contact your doctor or alternative practitioner.
