The herbal extracts of sage, Greek thyme, propolis and grapefruit effectively treat and cleanse the oral cavity. Sage oil and thyme oil, in addition to providing cool breath, have strong antibacterial and antimicrobial properties and therefore provide protection against plaque, the main cause of tooth decay in new teeth. Recent research confirms the antibacterial and antimicrobial activity of grapefruit extract. Propolis acts as an anti-inflammatory, antiseptic and antimicrobial, soothing the gums from inflammation (gingivitis) and neutralizing the germs that grow in the oral cavity. Stevia, a natural source of sugar, does not affect the health of the teeth.
