Introduction

Oral health plays a vital role in maintaining systemic well-being, as dental diseases can contribute to conditions such as cardiovascular infections and metabolic disorders [1]. Poor oral hygiene leads to plaque accumulation, gingival inflammation, and dental caries, which may progress to more serious oral and systemic complications. Tooth powders represent one of the oldest forms of dentifrices, historically used to clean teeth and improve oral hygiene [2]. Traditional cultures widely relied on natural powders made from herbs, bark, and minerals due to their simplicity, accessibility, and long shelf life.

However, many modern synthetic tooth powders contain harsh abrasives, detergents, and preservatives that may cause enamel wear, mucosal irritation, or taste disturbances upon long-term use [3]. These chemical components, although effective in cleaning, can disrupt oral tissues and natural microbial balance, increasing concerns about their prolonged use.

As a result, herbal dental formulations have gained considerable attention. Medicinal plants rich in phytochemicals—such as alkaloids, flavonoids, tannins, terpenoids, and saponins—exhibit antimicrobial, astringent, and anti-inflammatory effects beneficial for dental care [4]. These bioactive constituents help inhibit oral pathogens, strengthen gingival tissues, and support overall oral hygiene. Ayurveda and other traditional medicinal systems have long incorporated herbal agents such as Neem, Triphala, Acacia catechu, Clove, and Ginger for maintaining oral hygiene [5], demonstrating their long-standing therapeutic relevance.
