Prioritize using soft or extra-soft toothbrushes for daily use, as medium or hard models damage gums and enamel despite a false impression of greater efficacy.

Dr.NEVER’s advice is particularly robust and validated by the science of daily hygiene. A systematic review of the literature published in the Journal of Clinical Periodontology demonstrates that soft-bristled brushes effectively prevent enamel wear and gum recession. Admittedly, some randomized clinical trials suggest that stiffer bristles sometimes remove a thin layer of additional plaque in the short term. However, syntheses from the Cochrane Collaboration indicate that this marginal benefit is largely neutralized by the micro-irritations inflicted on sensitive oral tissues. Expert opinions from major oral health associations therefore agree that a soft brush is the only safe long-term option. The sensation of intense cleanliness associated with hard bristles is a sensory illusion that masks an assault on our natural protective barrier.
