Is it better to use a manual or battery powered toothbrush?

I have been using a battery powered one for a few years and my dentist says my gumline is getting to high meaning I am brushing too hard, but at the same time I haven't gotten any cavities while using the battery powered toothbrush. When I used the manual toothbrush I had a few more cavities, but my gumline wasn't affected.

Yes, a powered brush is much better. The rotations can reach much more than a manual brush. You can brush for 15 mins and not reach as much as 2 mins on a manual brush...I read somewhere. But yes, you do have to use less pressure than w/a reg brush. I had the same problem with my gums, they were taking a beating. Until my dentist taught me how. Let the brush do the work for you. Never, never scrub. When u scrub, even if u don't touch the gums, the vibrations can damage them. Go in tiny circles, gently tickling ur gums, spend a few seconds on each tooth them glide it to the next tooth. You don't have to apply much pressure. Let the brush to the work. If you keep pressing too hard, hold the brush with 3 fingers and glide. Most power brushes work better with less pressure. I use to use Oral b but switched to Sonicare, super soft bristles. It keeps my teeth really white, my doc said don't need teeth bleaching and kept the cavities at bay. But remember, no scrubbing and go gentle!
