- Does the TB20 need charging?
- No. It runs on disposable batteries, so there is no charging dock or cable. You replace the batteries when the brush slows down.
- How does it compare with a Philips Sonicare or Oral-B brush?
- It is a simpler, battery-powered brush. Those rechargeable rivals add multiple cleaning modes, pressure sensors and battery indicators that the TB20 does not have.
- What is in the box?
- The brush handle plus three brush heads. Batteries are not stated as included, so plan to have some on hand.
- Is it waterproof?
- Yes, the body is described as waterproof, so it can be rinsed under the tap. It is not stated as suitable for soaking or use in the bath.
- How does the 2-minute timer work?
- It times a two-minute brushing session. The material does not describe quadrant pacing or a vibration alert at the end.
- Can I use it with braces or sensitive gums?
- It has one pulsating mode, so there is no sensitive setting to switch to. Ask your dentist whether a single-mode sonic brush suits your needs.
