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.
You should look into a water flosser.
I’ve had them multiple times. Do not like, make a mess, pain to maintain.
I’ve never made a mess with mine - I have a waterpik which I can use with my mouth closed around it like when I brush my teeth.
But I have a big old cake hole to boot, so YMMV.
I saw a battery operated waterproof one that suggested you could use it in the shower. Seemed better than trying to keep the sink clean
