Why brushing harder is quietly wearing down your gums

It is an easy assumption to make: press harder, clean better. In practice the opposite is true. Plaque is soft and lifts away with light contact and a little time, while hard scrubbing mostly abrades the things you want to keep.

Over months and years, heavy pressure wears a wedge into the enamel near the gumline and pushes the gums to recede. Recession does not grow back. The tell-tale signs are new sensitivity to cold and teeth that look a little longer than they used to.

The fix is not to brush timidly, it is to let the brush do the work. A sonic brush is already moving thousands of times a minute; your job is to guide it gently along the gumline, not to scrub.

That is why AuraOne watches your pressure and eases off with a quiet cue when you bear down too hard. After a couple of weeks most people retrain the grip without thinking about it.
