Brushing harder doesn’t mean brushing better. Too much pressure can irritate your gums and wear down enamel. Focus on gentle pressure, small controlled movements, and brushing for a full two minutes—good technique beats force every time.

刷牙更用力，并不代表刷得更干净。过大的力度可能刺激牙龈，并增加牙釉质磨损的风险。刷牙时应保持轻柔力度，配合小幅度、可控制的动作，并坚持刷满两分钟——正确的刷牙技巧比用力更重要。
