Don't believe everything you read. This reads to me like a sonicare astroturfing. Electric toothbrushes in general are preferable to manual toothbrushes because if you use enough force that could do you harm, they stop working by design. Furthermore, a brush head becomes less able to do damage to your teeth or gums over time due to loss of strength and durability in the bristles (and by extension, less able to clean your teeth).
Gum recession is not caused by brushing too hard, it's caused by lack of flossing. If you're worried about gum recession, build a habit of flossing daily before bed
fuck. making mistakes with my teeth always makes me so fucking anxious
