Electric toothbrushes are a great way to improve your oral hygiene. They are more effective than manual toothbrushes at removing plaque and bacteria, and can help reduce tooth decay and gum disease. With so many different models on the market, it can be overwhelming to choose the right one. Electric toothbrushes generally fall into two categories: oscillating and sonic. Oscillating toothbrushes have a round head that rotates and oscillates back and forth, providing a scrubbing action to remove plaque and bacteria. Sonic toothbrushes, on the other hand, have a small, flat head with bristles that vibrate rapidly to provide deep cleaning. The most important factor in choosing between these two types is personal preference. You should also consider the size of the toothbrush head, the stiffness of the bristles, and whether the toothbrush is rechargeable or battery-powered. Other features to look out for include timers, pressure sensors, and different cleaning modes.

What You'll Learn
Electric toothbrush types: oscillating, sonic, or smart
Electric toothbrushes generally fall into two categories: sonic and oscillating. A third category, smart toothbrushes, is also available, but these are less common.
Sonic toothbrushes look similar to manual toothbrushes, with an oval or rectangular brush head. They vibrate gently and quietly, using a high-speed side-to-side bristle motion to break up plaque. They are also capable of vibrating in an up-and-down motion. Sonic toothbrushes are generally considered to be effective at removing plaque and reducing gum inflammation.
Oscillating toothbrushes, on the other hand, have a round head that rotates back and forth in a circular motion. Some models may also vibrate in addition to the circular motion of the brush head. They are also effective at reducing plaque and may be better suited for cleaning plaque in between teeth.
Smart toothbrushes are a more recent innovation, with features such as connected apps and artificial intelligence providing feedback on your brushing coverage. If you want to try a smart toothbrush, it is advisable to check the product's return policy, as they tend to be pricier.
Ultimately, the choice between sonic, oscillating, or smart toothbrushes may come down to personal preference. Both sonic and oscillating toothbrushes have been shown to be effective in reducing plaque and improving oral health. It is recommended to consult a dentist to determine which type of toothbrush will work best for your individual needs.

Toothbrush head shape and size
The shape and size of an electric toothbrush's head are important factors to consider when making a purchase. The two main types of electric toothbrushes are sonic toothbrushes and oscillating toothbrushes, and they differ in shape and size.
Sonic toothbrushes have a small, flat head with bristles that vibrate rapidly. To be classified as a sonic toothbrush, it must have a minimum of 50,000 vibrations per minute, which produces an audible hum. This type of toothbrush is ideal for those who want deep-cleaning vibrations.
Oscillating toothbrushes, on the other hand, have a round head that moves from side to side or rotates in a scrubbing motion. This type of toothbrush is more common and provides rapid cleaning action. Some oscillating toothbrushes may also pulsate, moving in and out against the teeth to further help dislodge plaque.
The size of the toothbrush head is also important. A toothbrush that is too large may not fit properly into the crevices of your mouth, resulting in missed debris and food particles. On the other hand, a toothbrush head that is too small may not provide adequate coverage. The ADA recommends using a toothbrush head that is no more than 0.5 inches wide by 1 inch long.
It's worth noting that electric toothbrushes come in various sizes and shapes, so it's important to find one that is compatible with your teeth and mouth. Smaller toothbrush heads can be advantageous for reaching tight spaces, while some individuals may prefer softer bristles for gum health.

Bristle stiffness
Recent studies have found that high bristle stiffness, when used with toothpastes that have medium-to-high abrasivity values, can contribute to the development of non-carious cervical lesions (NCCLs). NCCLs are a manifestation of abrasive dentine wear. Therefore, it is important to consider the abrasivity of your toothpaste when choosing the stiffness of your toothbrush bristles.
The interaction between toothbrush stiffness and toothbrushing force has not been fully evaluated, but some studies suggest that soft-bristled toothbrushes might respond differently to applied brushing force than harder ones. It is worth noting that the number of bristles per tuft and the different bristle diameters can also affect abrasive dentine wear.
Additionally, powered toothbrushes tend to come with soft bristles because the rotation and vibration already add extra pressure to your teeth, so firmer bristles are not necessary. If you brush your teeth too hard, it can lead to gum loss and tooth sensitivity, as well as potential damage to the enamel and tissues around your teeth.
Overall, when choosing an electric toothbrush, it is recommended to opt for one with soft bristles, especially if you tend to push harder against your teeth. This will help ensure that you effectively clean your teeth without causing any damage.

Battery type: rechargeable or disposable
Electric toothbrushes generally fall into two categories: those with disposable batteries and those with rechargeable batteries.
Disposable battery-powered toothbrushes are typically cheaper, ranging from $20 to $50. They are convenient, as you can simply replace the batteries when they run out of charge. However, they are not as environmentally friendly as rechargeable toothbrushes, as they generate more waste and can leak if not removed in time.
Rechargeable electric toothbrushes, on the other hand, tend to be more expensive, with prices ranging from $100 to $200. They offer a more sustainable option, as you don't have to dispose of batteries as frequently. These toothbrushes usually have built-in rechargeable batteries, such as lithium-ion batteries, which offer longer life and better energy density. Higher-end electric toothbrushes with rechargeable batteries often come with additional features, such as different cleaning modes and smart functions.
When choosing between a disposable or rechargeable electric toothbrush, consider your budget, convenience, and environmental impact. If you opt for a rechargeable toothbrush, look for one with a lithium-ion battery for longer battery life. Additionally, consider the voltage and capacity of the battery, ensuring it matches your toothbrush's requirements and provides sufficient use time.
It is worth noting that some rechargeable electric toothbrushes, like the Oral-B Vitality, may experience a decline in battery performance over time, requiring more frequent charging. In such cases, you may need to replace the battery.

Extra features: timers, sensors, modes
Electric toothbrushes can come with a variety of extra features, such as timers, sensors, and modes, which can help improve your oral hygiene.
Timers are one of the more basic features of an electric toothbrush, with most having two-minute timers, as this is the dentist-recommended amount of time to brush your teeth. Many also have 20- or 30-second notifications to guide you as you brush, reminding you to move on to the next quadrant of your mouth. Some toothbrushes will buzz or automatically power down after two minutes of brushing, while others will not auto-stop.
Pressure sensors are another common feature of electric toothbrushes. These monitor and alert you to ease up if you are brushing too hard, protecting your enamel and gums. Some toothbrushes have lights that display green when you are brushing with the correct amount of pressure, and red when you are brushing too hard. Other toothbrushes have AI technology that uses this data to teach you how to brush the right amount and apply the correct pressure.
Some toothbrushes have multiple modes with different intensities and settings, such as 'whitening', 'gum health', 'clean', and 'sensitive'. However, these modes are often just marketing terms, and the speed of the vibrations is the main differentiator between them.
Other features to look out for include Bluetooth connectivity, which allows toothbrushes to sync with a companion app to track brushing habits and receive tips to enhance your routine.
