2. enamel is far too strong to be abraded by the brush, what does get abraded is the dentin (the yellowish part closer to your gums, that's why sometimes you can see small dent-like abrasions there) so try to focus on brushing softly in those areas. A good idea is to use soft bristles
All you do is good and you're probably already doing 95% of what can be done, the other risk factors are smoking, female hormones, stress and diet. If you are not stressed, don't smoke, are male and eat mostly plant-based whole foods you can't do much more than that

I am not a dentist but have similar issues:
Consider wearing a mouthguard at night? Grinding teeth during sleep can contribute hugely to bone loss.
Also make sure you're using the rubbertip correctly. It's supposed to massage the gum with the flat part, not poke with the pointy part.
Teeth are pretty hard on the Moh's scale relative to bristles. If you're abrading enamel, it's from something in the toothpaste (which has all kinds of mineral abrasives), or tooth-tooth contact from chewing/grinding.
1. my hygienist said it made no difference in plaque formation on my teeth (I did A-B experiments)
2. I was concerned it was abrading the enamel.
I'm old, btw, and am mostly concerned about receding gums and bone loss. I brush, floss, use the pipe cleaners for between teeth, and run one of those pointy rubber things along the gum line, and still get gingivitis. My dentist says there's nothing more I can do about it.
I've also tried various mouthwashes, which made no difference.
Anything else I can try?
