Formulation of Herbal Tooth Powder Employing Quercus infectoria as a Potential Agent for Oral Care and Microbial Infections

Herbal remedies for oral care are increasingly popular due to their safety, affordability, and compatibility with the mouth's natural bacterial balance. This study develops and evaluates herbal tooth powder using Quercus infectoria (oak galls), Triphala (Amla, Haritaki, Bibhitaki), Liquorice (Glycyrrhiza glabra), black salt, and calcium carbonate to prevent oral infections. The objective was to create an effective alternative to conventional dental products. The tooth powder was formulated and tested through physicochemical, rheological, microbiological, patch, and sensory evaluations. The pH level of 5 is ideal for oral applications, balancing effective hygiene and gentleness. Physicochemical evaluations show a moisture content of 1.64% (indicating stability and low microbial risk), an ash value of 0.58% (acceptable limits), and a bulk density of 4g/ml (ensuring good flow and consistent dosing). The effective minimum inhibitory concentration of 0.1 mg/ml highlights the active compounds' potency in inhibiting bacterial growth. Key findings showed it had strong antibacterial, antimicrobial, anti-inflammatory, and antioxidant properties. Tannic acid from Quercus infectoria was effective against oral infections, while Triphala and Liquorice added antibacterial benefits and improved flavour. This study underscores the potential of herbal tooth powders as a natural, effective solution for oral hygiene and infection prevention.
