Are sonic toothbrushes BS ? Do they make any noticeable difference ?

\*Ultrasonic, i meant the one that produces waves that break the scale

I need somebody who's not a salesman to tell me if they are bullshit or not because I won't spare an expense on my teeth but it's hard to justify spending a quarter of my monthly income on something that only maybe works.

Also do you think there is much difference between 200usd sonic toothbrush and 400 USD one ? In terms of cleaning, not quality of materials and durability.

Thank you everyone for responding, special thanks to dentists for answering.

Dentist here. Yes it’s worth it. There is evidence electric toothbrushes do remove more plaque than manual toothbrushes. Also learned from a few periodontists that the circular spinning action of Oral-B is better than Sonicare’s vibration. If you use  Sonicare, go in small circles at a 45 degree angle into the gums when brushing the cheek/lip surface as well as the palate/tongue surface. No, the most expensive ones aren’t worth it unless you have lots of disposable income. They all fundamentally work the same, except the expensive ones have more bells and whistles. There’s a oral b pro 1000 on sale for 30 bucks at Best Buy. It’s the replacement heads where they get you. There’s countless pubmed articles backing up this claim. Don’t forget to floss and get your cleaning every 3-6 months.
