I quit using electric toothbrushes.
I have a Philips Sonicare and my gums kept bleeding.
I have never had the issue, beforehand, when using OralB.
The dentist told me my gum line was thin and just put Corsodyl gel on it after brushing. Shrugged it off.
A few months later, came across a YouTube dentist who said that Philips are not suitable for a lot of people because the brushes are too aggressive.
Never mentioned this to my dentist. Went for a check up. He asked me what brush I used (again). He said my teeth were 'impeccable'.
Told him I used manual because Philips made my gum line bleed.
He says, "Oh, I don't recommend those because they are very aggressive. Try OralB!"
After all of those years and all of the money I spent on heads etc!
Manual, soft, Colgate £1 for me.
