Toothbrushes are essential oral hygiene tools designed to remove plaque and maintain oral health.

They effectively disrupt bacterial biofilms on tooth surfaces, significantly reducing the prevalence of dental caries and periodontal disease. While improper use can cause minor tissue abrasion and disposable designs contribute to plastic waste, their overall public health utility is exceptionally high.
