The biggest thing is to ease off the pressure - a lot of people grip electric toothbrushes like they're scrubbing a floor, but you really just need to let the brush do the work and guide it gently. If your gums are already inflamed, give them a few days of gentle care before jumping to conclusions about the toothbrush itself; sometimes the bleeding improves once you dial back the force. One pitfall nobody mentions: if you switch from manual to electric, your gums might bleed for the first week or two as they adjust to the different motion, but that's usually temporary. If it persists after a week of being gentle, or if there's swelling or pain, that's worth getting checked out because it could signal something like gingivitis that needs actual attention.
Bleeding usually means your gums are inflamed, and an electric toothbrush - especially if it's set to a higher intensity - can aggravate that inflammation or you might be pressing too hard against your teeth. If your gums are already irritated from plaque buildup or early gum disease, even gentle brushing can make them bleed at first. Try dialing back the intensity if your brush has that option, make sure you're not jamming it against your gum line, and if the bleeding doesn't stop in a week or two of careful brushing, that's worth getting checked out by a dentist since it could signal something that needs attention.
One thing people don't always think about is switching to a softer brush head - most folks grab whatever came in the box, but if you've got sensitive or inflamed gums, a "soft" or "extra soft" head makes a real difference compared to the medium ones. Also worth checking: are you brushing your gums themselves or mainly the teeth? Electric brushes can catch the gum line differently than manual ones, so aim the bristles at a 45-degree angle *away* from the gum rather than straight into it. If the bleeding doesn't stop after a few weeks of gentler technique and a softer head, that's worth mentioning to a dentist because it could signal something like early gum disease that needs attention.
