It sounds like you’re referring to a traditional oral-care plant, but your message is missing the actual image or name.
In dentistry, the most commonly “plant-based” tool or recommendation for patients is:
🌿 Miswak (Siwak)
Salvadora persica
This is a natural chewing stick from the Salvadora persica tree. It’s been used for centuries and is still common in many Muslim-majority regions. Some dental professionals recommend it as a natural toothbrush because it contains antimicrobial compounds that can help reduce plaque and gum disease.
Other possible plants you might be thinking of:
🌿 Neem
Azadirachta indica
Neem twigs and extracts are also traditionally used for dental hygiene, especially in South Asia.
🌿 Clove
Syzygium aromaticum
Clove oil is commonly used by dentists for temporary relief of tooth pain due to its natural anesthetic properties.
If you meant a specific plant shown in an image, upload it and I can identify it exactly.
