Diversity and conservation status of plant species used for oral and dental management by the inhabitants of Bayelsa State, Nigeria were assessed. Information on the indigenous knowledge of the plant species use was obtained via semi-structured questionnaire guide, and field trip involved key informants. Species used for oral and dental care were identified, and their relative abundant status determined. The study revealed that different kinds of plant with varied growth habits were used for orodental care; however some of the plants are becoming rare due to unprecedented deforestation. Fidelity level (FL), and Respondents Consensus Factor (RCF) revealed the relative importance and level of respondents’ reliance on the plants. The study further showed that leaves, roots and plant inflorescence played significant role in oral treatment either singly or in combination of other plant parts steeped in ogogoro, a local gin. Many of the plants assessed were obtained from the wild, forest being their primary source. Thus, with the increasing level of deforestation in the State and the unsustainable collection pattern, combined with blasé attitude, the consequence of erosion of culture: it becomes pertinent to document information of plant species used for oral and dental management in the State.
