Rating (out of 5): 2

Areca, commonly known as betel nut, has a long-standing traditional use in various cultures, particularly across South and Southeast Asia, as a masticatory substance. People often chew areca nut wrapped in betel leaf, sometimes with slaked lime, as part of social, cultural, and ritual practices. Traditionally, it has been believed to strengthen gums and support oral hygiene, as the chewing action stimulates saliva production and may help in cleaning the teeth superficially. However, while its use is entrenched in tradition for supporting oral health, modern scientific studies overwhelmingly associate areca nut chewing with significant adverse effects on the teeth and oral cavity. Evidence shows that chronic use leads to dental staining, periodontal disease, and a markedly increased risk of oral submucous fibrosis and oral cancers. There is a lack of reliable scientific evidence supporting any beneficial effect of areca on dental health; rather, research highlights its role as a risk factor for oral disease. In summary, while traditional beliefs support its use for teeth, current science strongly warns against it due to proven harm.
