Brushing your teeth too frequently, with excessive pressure, or with an overly abrasive toothpaste can cause enamel erosion, increase tooth sensitivity, and create grooves at the base of the gums.

The creator's advice is based on solid physical and wellness principles. A systematic review published in the Journal of Pioneering Medical Sciences (2025) confirms that excessive brushing frequency, poor technique, and the use of stiff bristles are directly correlated with premature wear of the junction between the tooth and the gum. In parallel, a literature review published in the journal MDPI (2025) notes that the abrasivity index of toothpaste and excessive brushing pressure are the primary causes of this enamel loss. A synthesis published in Karger (2014) also explains that vigorous brushing immediately after an acidic meal removes the surface layer of the tooth before it can naturally remineralize. However, the concept of 'too frequent' brushing warrants clarification: maintaining two daily brushing sessions with a gentle technique remains an essential habit, with the risk appearing only in cases of repeated, aggressive brushing. Therefore, the problem lies less in the regularity of the hygiene ritual than in the use of inappropriate equipment and highly stripping formulas, such as certain whitening toothpastes.
