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.
For the record, electric toothbrushes are shown to clean better than manual ones, but there is very little difference between a cheap electric or expensive electric toothbrush. The cheapest Oral B the sell at the supermarket is basically as good as the super expensive one.
