In this guide, we explore four traditional uses of neem for oral health, the available scientific evidence, how the traditional preparation is made, and important precautions to consider before using it.
- Neem and Dental Plaque Control
Dental plaque is a sticky film of bacteria that forms on the surfaces of teeth. If it is not removed regularly, it can contribute to tooth decay and gum inflammation.
Neem contains naturally occurring compounds, including flavonoids and other phytochemicals, that have attracted scientific interest because of their biological activity.
Researchers have investigated neem extracts and neem-containing oral care products for their potential effects on microorganisms associated with dental plaque.
A randomized clinical trial published in 2015 evaluated neem-containing toothpaste in 30 participants. The researchers reported improvements in plaque and gingival indices after the intervention. However, the study was small, so its findings should be interpreted cautiously.
What does this mean for everyday oral care?
Neem may have potential as an ingredient in formulated oral care products, but there is not enough evidence to conclude that homemade neem leaf powder provides the same benefits.
