How to Choose an Electric Toothbrush

Electric toothbrushes range from simple to very expensive. The features that help most are found on inexpensive models too.

Oscillating vs sonic

Oscillating-rotating brushes, mainly from Oral-B, use a small round head that spins back and forth. Sonic brushes, such as Sonicare, use a traditional-shaped head that vibrates very quickly from side to side.

Both types clean well when used properly. Choose based on feel, noise and the cost of replacement heads.

Features that matter

These help most people brush better:

  • A two-minute timer, ideally with 30-second prompts to move to the next area
  • A pressure sensor, which warns you if you're pressing too hard
  • Affordable, easy-to-find replacement heads

Features you can skip

App tracking, many brushing modes and colored handles are nice to have but don't make a big difference for most people.

Count the running cost

You'll replace the head about every three months. Over a few years, head prices can matter more than the price of the handle.

Frequently asked questions

Can I use an electric toothbrush with braces or sensitive teeth?

Many people do, and some brushes offer sensitive modes or special heads. Ask your dentist or orthodontist for a recommendation.

Can family members share a handle?

Yes, as long as each person uses their own brush head. Many brands sell colored rings to tell heads apart.
