I go to the dentist annually, brush twice daily and floss 3 or 4 times a week, but man oh man is this electric toothbrush a whole new world…my teeth feel dentist clean each time. By no means was my mouth poorly taken care of, but it feels in a different world now.
If you can, get one ASAP.
I have an oral b one from 10 years ago that takes AA batteries. Got some eneloop rechargeables for it and it’s been great since. Don’t have to leave it on the counter to charge or worry about the built in battery wearing out.
