Wondering which is the best electric toothbrush? Or maybe you’re still pondering the great debate — electric toothbrush vs manual.

The truth is both types of toothbrushes are effective at maintaining good oral care. But only if you have the right technique. Let’s look at the pros and cons of an electric toothbrush vs manual toothbrush. Plus, get our views on the best electric toothbrush and, most importantly, how to brush properly.

Electric vs manual toothbrush: The pros & cons

Regular teeth brushing is the cornerstone of good oral care. It helps to remove bacteria and dental plaque that cause tooth decay and gum disease. To brush your teeth effectively you need toothpaste and either a soft-bristled manual or electric toothbrush. 

Which type of toothbrush is best comes down to personal preferences. To help you decide which one is right for you, here are the pros and cons of each one.

Electric toothbrush — Pros

Effective at removing plaque

Studies have shown that electric toothbrushes are equally as effective as manual toothbrushes. Although more recent data indicates that the rotating (oscillating) bristles of an electric toothbrush are better at removing plaque and reducing the risk of gingivitis.  

Easier for people with limited dexterity

People with reduced dexterity may find it easier to hold and move an electric toothbrush. The oscillating bristles do most of the work for the user, while the thicker handle can be easier to grip.

 

Built-in timer promotes thorough brushing

Most electric toothbrushes come with a built-in two-minute timer. This ensures you brush for a full two minutes, as recommended by dentists to ensure a thorough clean.

Useful for orthodontic patients

Electric toothbrushes can be an effective alternative to manual toothbrushes in people with fixed braces. The moving bristles can make it easier to move around wires and brackets. 

Fun for kids

Many kids find electric toothbrushes more interesting and fun, which may improve their focus while brushing. Meanwhile, the built-in timer can help ensure children brush their teeth for the recommended time. 

Electric toothbrush — Cons

Cost 

Electric toothbrushes are more expensive than manual toothbrushes. Replacement heads vary in price but, typically, cost more than a new manual toothbrush. 

Need for batteries

This type of toothbrush needs batteries or regular charging to operate. This can be inconvenient and may affect the efficacy of brushing.

Less convenient for travel

Electric toothbrushes vs manual toothbrushes are heavier and bulkier, making them less convenient for travel. You may also need an adaptor (depending on where you are travelling to) to charge the toothbrush.

Manual toothbrush — Pros

Cost effective & convenient

Manual toothbrushes cost less than electric toothbrushes. Plus, if you forget your toothbrush, it’s easy to find a new one at your local convenience store, chemist, supermarket or petrol station.

Personalised control

With manual brushes, the user is in control of the pressure and brushing technique. Also, the toothbrush head can be used to clean the tongue.

Travel-friendly

Manual toothbrushes are compact and lightweight, making them great for travel and on-the-go oral care. No batteries or chargers needed!

Eco-friendly

Unlike electric toothbrushes, manual toothbrushes don’t rely on electronic components, which makes them more environmentally friendly (particularly if it’s a bamboo toothbrush).

Manual toothbrush — Cons

No built-in timer

Without the timer, it’s easier to underbrush which can lead to a build-up of plaque or enamel wear.

Effectiveness

Manual toothbrushes may be less effective at removing plaque, as they don’t have the benefit of an oscillating head. However, with the right brushing technique they can be equally as effective as an electric toothbrush. 

Manual brush vs electric toothbrush: What do we recommend?

This really depends on your personal preferences and needs. If dexterity issues affect your brushing technique your dentist may recommend an electric toothbrush. On the other hand, if you have a good brushing technique there’s no reason why you should change from a manual toothbrush.

TIP:  There’s no substitute for bristles. The rinsing action of water flossers can’t remove plaque completely from the surface of your teeth. Plus, they can be messy!

Which are the best electric toothbrushes?

The electric toothbrush we most often recommend is the Oral B Vitality. However, finding the best electric toothbrush comes down to personal choice. There are several factors to consider. This includes the price, the handle shape, the size of the toothbrush head, and charging methods. You might also be guided by features such as pressure sensors and range of cleaning modes.

Brushing up on technique

With manual brushes, the user is in control of the pressure and brushing technique. Also, the toothbrush head can be used to clean the tongue.

When using a manual toothbrush, proper brushing technique involves:

  • Holding your toothbrush at a 45-degree angle to the gums. 
  • Gently moving the toothbrush over the surface of each tooth and the gumline in small, circular movements. 
  • Cleaning the inside surfaces of the front teeth by tilting the brush vertically and making several up-and-down strokes.
  • Using a back-and forth movement to brush the chewing surfaces of the teeth.

To brush your teeth using an electric toothbrush:

  • Hold the brush at a 45-degree angle, like you would a manual toothbrush.
  • In a systematic fashion, move the brush from tooth to tooth. Hold the brush in place for a few seconds before moving it to the next tooth.
  • Make sure you use the brush on all surfaces, front and back, inside and out. We often notice people spend less time brushing the harder to reach surfaces behind the teeth, and this is why people tend to have more gum inflammation at those sites.

REMEMBER: Whether you use an electric or a manual toothbrush, you should change your toothbrush or brush head every three months. If you wear fixed braces, you may need to change your toothbrush more frequently as the bristles may become frayed sooner.

Final thought…

Cleaning your teeth well is difficult because you can’t see what you are cleaning. Toothbrushing technique, accuracy and frequency is far more important than the type of toothbrush you have. Both electric and manual toothbrushes are effective at removing plaque—providing you have a good technique. Ultimately, the best toothbrush is the one you like and can use effectively. You should ask for feedback from your dental practitioner to know if your technique is good or not.

Think you might have gum disease?

Don’t despair. Every stage of gum disease is treatable.
