Four Mistakes You Are Making While Using An Electric Toothbrush

Disclosure: Noelle Copeland RDH is the oral care specialist and dental consultant to the Brilliant and Baby Buddy oral care lines.

Tooth Brushing mistakes are pretty standard, whether you are using an electric toothbrush or a manual one. I think my kids cornered the market with their ability to look like they were brushing their teeth, while in reality, they were barely getting the bristles around their mouth. For kids, it takes constant supervision and assessment.

Electric toothbrushes can make oral care a little easier for pesky little brushers who push the boundaries of maintaining self-care independently and consistently. Adults benefit for the same reasons as kids do. Bear in mind; however, electric toothbrushes are more powerful and can be misused a lot easier than their manual counterparts. Today I’m reviewing four common mistakes often made when using an electric toothbrush.

Mistake #1 Not Following The Manufacturer’s Directions

Each electric toothbrush should have specific instructions created by the manufacturer included for your education. For instance:

Rotating-Oscillating Electric toothbrushes-

  • Have small circular brush heads that rotate rapidly back and forth, like a windshield wiper.
  • When using this type of toothbrush, the brushing technique should be applied to one tooth and then the next tooth.
  • Brushing with a sweeping “back-and-forth” brush stroke is not recommended for this style because the brush head should “hug and cup” each tooth individually.
  • Instead, place the rotating brush head on each tooth for about 2-5 seconds, repeating on all tooth surfaces.
  • The surfaces to reach are the front side of the teeth, the tongue side of the teeth, and the chewing tops of the teeth.

Sonic Electric toothbrushes-

  • Have rectangular brush heads and use vibration technology to loosen plaque and bacteria from the teeth.
  • They come in various frequencies with gear adjusting modes that account for desired results or particular circumstances like; Sensitive, Whitening, Deep Clean, Clean, Gum Care.
  • The frequency strength determines the brushing method and technique to follow when being used.
  • There are two main types of sonic electric toothbrushes:
    Rechargeable High-Frequency models and Battery Powered Low-Frequency models.

High-Frequency Sonic Toothbrush

A Sonic toothbrush with a 25K-45K frequency range, which’s considered a high-frequency sonic toothbrush, should be used by guiding it over the teeth. You are driving the brush around your mouth. It’s so powerful that you don’t need any pressure or scrubbing motions to move the bristles back and forth to remove plaque; the high frequency drives the bristles for you, so all you have to do is get the brush in your mouth and aim it correctly. Greater caution is required with high-frequency designs as they are more accessible to misuse and can cause gum tissue recession and sensitivity.

  • Option for persons over the age of eight years.
  • Greater plaque control.
  • Helpful for those with dexterity challenges.
  • Creates more vibrations that may be cumbersome to acclimate to.
  • The motor is louder and could be bothersome while using.
  • Use with caution on those with sensory disorders.
  • Not recommended for those with generalized recession concerns.

Low-Frequency Sonic Toothbrush

On the other side of the sonic toothbrush spectrum is low-frequency sonic toothbrushes, typically battery-powered units. Designs range from 10k- 20k. While they are much less powerful, they still provide sonic vibrations and power waves within the mouth to help remove plaque and bacteria. These waves are more tolerable and gentle, especially for sensitive mouthed individuals. Low-powered units require the regular brushing patterns most people are used to performing, brushing back and forth or in small circles.

  • An excellent option for children.
  • Travels easier since most use batteries instead of charging units.
  • Less expensive, generally.
  • Much less vibration to get used to, higher compliance rate.
Mistake #2 Not Using The Brushing Timer

One of my favorite features of an electric toothbrush is the built-in timer. You’d be surprised by how many people brush for less than 30 seconds! Having a built-in timer keeps you accountable for brushing purposefully and for long enough. The ADA recommends that everyone brush for at least two minutes, twice a day. This timer helps ensure you reach all the areas of the mouth. Most electric toothbrushes have a built-in 2-minute timer, with pulsing indicators for quad-paced brushing habits. Recently, some manufacturers have extended the brushing timer from 2 minutes to 3 minutes to encourage even more brushing accountability. Use your electric toothbrush until it shuts off on its own; that is your built-in accountability partner for oral care. Consider it your oral care trainer.

  • Accountability.
  • Oral Care Training.
  • Connect to dental apps to engage children and keep track of brushing.
Mistake #3 Not Changing The Brush Head Every Three Months

It’s easier to use an electric toothbrush head past its expiration time; for one reason, they are more expensive to replace, so I find that some will try and push the usage past a reasonable time frame. Any toothbrush needs to be regularly rotated every three months and sooner if the bristles are worn. Something to consider from the opposite side of the table is; if you are wearing your bristles down before a 3-month mark, you need to ponder that you may be brushing too aggressively. It’s best to consult with a dental professional to confirm this and go over this concern.

  • Toothbrush bristles accumulate bacteria and toothpaste residue.
  • Older bristles remove less plaque and bacteria.
  • Older bristles wear down and start the lose their elasticity.
Mistake #4 Using Incorrect Pressure/Scrubbing

Some people are just heavy-handed brushers. They do a great job scrubbing away the plaque on their teeth, along with scrubbing away their tooth enamel. That applies to manual toothbrush users and electric toothbrush users. However, pressure per square inch amplifies if you are also using an electric toothbrush. Most dentists will not recommend an electric toothbrush to patients with very sensitive teeth, recession, or severe gum issues.

On the other side is not using enough pressure, and this comes into play quite often for kids who get the brush in their mouth but end up doing minimal “brushing” with it. Parental supervision is necessary. The best tools are utterly useless if they are misused. One of the benefits of an electric toothbrush for children is that higher-frequency toothbrushes do the work. However, kids still need to know how to brush correctly and gauge the appropriate pressure. My recommendation is:

  • Start with a manual toothbrush and strictly use that to brush train your child.
  • Then, once they can mimic your instructions, you can introduce a battery-powered sonic toothbrush.
  • A battery-powered sonic toothbrush is less jarring and does not tickle the mouth as much, preventing compliance aversion.
  • Then when a child is older, eight years+, you can try a higher frequency sonic toothbrush.
