Electric toothbrushes promise a better clean, but the choice between brands, models and prices can be confusing. This guide explains what an electric toothbrush actually does, how the two best-known brands, Oral-B and Philips Sonicare, differ, which features are worth paying for, and where to find genuine products. It builds on our daily oral hygiene guide, because even the best brush only works if you use it well.
What an electric toothbrush does
A powered brush moves the bristles for you, so your job is to guide the head slowly from tooth to tooth instead of scrubbing. Most models also include a two-minute timer and some include a pressure sensor, which helps people who brush too hard or too fast. Electric brushes are not magic, and a manual brush used carefully can also clean well. They are most helpful for people who rush, press too hard, have limited hand movement, or wear braces. Whatever you buy, use it with a fluoride toothpaste, twice a day.
The two main designs
- Oscillating-rotating (Oral-B). A small round head that spins one way and then the other, and pulses. You hold it on each tooth for a moment.
- Sonic (Philips Sonicare). A more traditional oval head whose bristles vibrate very quickly from side to side. You glide it along the teeth and gumline.
Both approaches can remove plaque effectively when used correctly. Brands publish their own studies comparing themselves with competitors, so treat those claims with care. Independent reviewers generally say the most important factor is choosing a brush you will actually use twice a day.
The ADA Seal and electric toothbrushes
The American Dental Association (ADA) runs a voluntary Seal of Acceptance that tests safety and effectiveness claims. When the ADA first awarded the Seal to power toothbrushes in 2017, it went to several Oral-B lines. Acceptance applies to specific products, not whole brands, and the list changes over time. A brush without the Seal is not necessarily poor, because manufacturers must choose to apply. Before you buy, check the exact model in the ADA’s product search. Our guide to checking the ADA Seal shows how.
Features that are worth having
- A built-in two-minute timer. Many models also pulse every 30 seconds to remind you to change area.
- A pressure sensor. It warns you if you press too hard, which can harm gums over time.
- A gentle or sensitive mode. Helpful if your gums or teeth are easily irritated.
- A brush head replacement reminder. Heads should be replaced about every three months.
- Battery life and a travel case. Useful if you travel often.
Features you can skip
- App connectivity and tracking. It can motivate some people, but it is not necessary for a good clean.
- Many cleaning modes. Most people use one or two.
- Premium finishes. They affect looks, not cleaning.
Check the running cost
The handle is only part of the cost. Replacement heads are needed regularly, so look at the price and availability of heads for the model before you buy. Compatible heads from other makers exist, but quality varies, so buy from the brand or a reputable seller.
Who benefits most
- People who tend to brush quickly or press too hard
- People with limited hand strength or dexterity
- People with braces or other dental appliances, who need thorough cleaning
- Children, using a model designed for kids and with supervision
How to use it
- Wet the head, add a small amount of fluoride toothpaste and place it against the tooth before switching on.
- Guide the brush slowly over each tooth surface without scrubbing.
- Brush for two minutes, covering all surfaces and the gumline.
- Spit out the excess toothpaste but do not rinse with water.
- Rinse the head, let it air dry and replace it about every three months.
Technique details are in our guide to brushing properly.
Where to find genuine products
- The brands’ own websites. Oral-B and Philips both sell and list their current models, with specifications. Start at oralb.com or the Philips Sonicare section of philips.com for your country.
- Established retailers. Pharmacies, supermarkets, electronics stores and large online shops all stock these brands. Prices vary by country and change often with sales, so compare a few sellers.
- Be careful with unbranded sellers. Very cheap “compatible” or branded heads from unknown marketplace sellers may be counterfeit or poorly made. Buy from the brand or a seller you trust, and check the packaging.
We do not list prices because they change constantly and differ between countries. If a retailer link is added to this site in future, it will be labelled clearly. See our Editorial Policy.
The bottom line
Pick a model from a well-known brand with a timer and pressure sensor, check whether the exact model has the ADA Seal, and look at the cost of replacement heads. Then use it correctly every day. For questions about your own gums or teeth, ask your dentist. You can also contact us with questions about this guide.
