I’ve been using Sonicare toothbrushes for years, and I must say, they have entirely changed my oral hygiene routine. The powerful vibrations and gentle bristles make it easy to keep my teeth clean and healthy. Generally, Sonicare toothbrushes do not harm teeth.

However, I’ve come across many people who have experienced tooth cracking while using Sonicare toothbrushes. That got me thinking, what causes this issue, and how can it be prevented?

Now I will share my knowledge and expertise to help you understand the causes of tooth cracking with Sonicare toothbrushes and provide 6 important tips to prevent it.

How Sonicare Toothbrush Works?

Before we dive into the causes of tooth cracking with Sonicare toothbrushes, let me briefly explain how these toothbrushes work:

Sonic toothbrushes revolutionize dental care with their advanced technology and superior performance. Unlike traditional toothbrushes that oscillate and spin, Sonic toothbrushes use high vibration frequencies to generate an impressive 31,000 strokes per minute.

This remarkable speed allows for dynamic cleaning process, effectively reaching between the teeth and below the gum line. The secret behind Sonicare’s trademarked sonic technology lies in its ability to propel fluid deep into the spaces between teeth and gums. This action not only ensures a thorough cleaning but also promotes healthier gums.

By gently vibrating at such a high frequency, Sonic toothbrushes offer a gentler brushing experience, preventing the risk of overbrushing that could potentially damage the enamel.

To experience the full benefits of a sonic toothbrush, it is essential to use it correctly. With Sonicare, you can leave the work of brushing your teeth to the toothbrush itself. Simply divide your mouth into quadrants and let the toothbrush do the rest.

Specific models even have a built-in timer that alerts you when it’s time to switch to a different quadrant, ensuring a thorough and efficient clean.

Causes of Tooth Cracking with Sonicare Toothbrushes

While Sonicare toothbrushes are highly effective at cleaning your teeth, there have been instances where they can cause tooth cracking. It’s important to note that tooth cracking can occur with any electric toothbrush if not used properly.

Now, I will discuss the various causes that can contribute to tooth cracking when using Sonicare toothbrushes. Knowing the causes will help you better understand how to prevent them:

Improper Brushing Technique

The improper brushing method and aggressive brushing may cause your teeth to chip. We all know that brushing our teeth is crucial for maintaining good oral hygiene. However, using the wrong brushing technique or being too aggressive can adversely affect our teeth.

Regarding Sonicare toothbrushes, it is essential to use a gentle and circular motion rather than scrubbing back and forth vigorously. Doing so can prevent unnecessary pressure and reduce the risk of tooth cracking.

Excessive Brushing Duration

The likelihood of chipping may be raised by over brushing or brushing for a prolonged time. While it may seem like the more we brush, the cleaner our teeth will be, over brushing can actually harm our teeth. Sonicare toothbrushes are designed to provide optimal cleaning in a shorter period.

Brushing for an extended time or excessively can lead to tooth sensitivity and crack-prone teeth. Following the dentist-recommended brushing time of two minutes twice a day is recommended to avoid any potential tooth cracking.

Bristle Hardness

Chipping might result from using an electric toothbrush with tough bristles. The bristles of a toothbrush play a significant role in removing plaque and debris from our teeth. However, using an electric toothbrush with tough bristles, such as some models of Sonicare, can increase the risk of tooth cracking.

The excessive force exerted by these tough bristles can cause stress on the teeth, leading to cracks over time. Opting for a Sonicare toothbrush with softer bristles can be a better choice for preventing tooth cracking.

Poor Toothbrushes’ Quality

The bristles or other components of a low-quality electric toothbrush might possibly damage teeth. Not all toothbrushes are created equal, and the quality of the toothbrush you choose can impact your dental health. Low-quality electric toothbrushes, including some generic Sonicare alternatives, may have bristles or other components that can damage your teeth.

The bristles may be too abrasive or prone to wear and tear, leading to tooth cracking. Investing in a high-quality Sonicare toothbrush can minimize the risk of damage to your teeth.

Tooth Weakness

An electric toothbrush may exacerbate existing dental problems, such as decay, that have made your teeth more vulnerable to chipping. If you already have underlying dental problems, such as tooth decay or weakened enamel, using an electric toothbrush like Sonicare may worsen the condition.

These dental issues can make your teeth more susceptible to cracking, and the vibrations and pressure from the toothbrush can exacerbate the problem. Addressing any existing dental concerns with your dentist to prevent further damage is crucial.

Excessive Brushing Pressure

Excessive pressure might result in chipping when using an electric toothbrush. While Sonicare toothbrushes are designed to make brushing easier and more effective, applying excessive pressure can cause tooth cracking.

The vibrations and power generated by the electric toothbrush are sufficient to remove plaque and debris without the need for excessive force. You can protect your teeth from potential cracks by being mindful of the pressure you apply while brushing.

6 Ways To Prevent Sonicare Toothbrush Tooth Cracking

Sonicare toothbrushes are among the best electric toothbrushes in the market, offering superior cleaning power and performance. However, you already know that misusing these toothbrushes can cause tooth cracking. Tooth cracking is a severe dental problem that can lead to pain, sensitivity, infection, and even tooth loss.

Therefore, knowing how to prevent tooth cracking with Sonicare toothbrushes is important. Now that we know the causes, let’s explore 6 practical tips to avoid tooth cracking when using Sonicare toothbrushes:

1. Use The Right Brushing Technique

The way you brush your teeth matters a lot when it comes to preventing tooth cracking. Sonicare toothbrushes work by creating high-speed vibrations that remove plaque and bacteria from your teeth.

However, using an incorrect brushing technique or applying too much force can damage your teeth. To avoid this, you should follow the manufacturer’s instructions and use gentle circular motions to brush your teeth. Don’t scrub or press too hard, as this can cause cracks in your enamel.

2. Use The Right Brushing Mode

Sonicare toothbrushes have different brushing modes, such as Clean, White, Gum Care, and Sensitive. Each mode has a different intensity and duration of brushing. You should select the mode that matches your oral health needs and preferences.

If you are new to using a Sonicare toothbrush, you may want to start with the Sensitive mode, which is the gentlest option.

3. Brush For The Required Amount Of Time

Brushing your teeth regularly is essential for maintaining good oral hygiene, but brushing for too long or too often can harm your teeth. Over Brushing can wear down your enamel and make your teeth more prone to cracking.

Sonicare toothbrushes are designed to be efficient, so you don’t need to brush for more than the recommended time of 2 minutes. Most Sonicare toothbrushes have a timer that tells you when to stop brushing. Follow the timer, and don’t overdo it.

4. Use A Soft Bristle Toothbrush

The bristles of your electric toothbrush play a crucial role in cleaning your teeth effectively. However, using a Sonicare toothbrush with hard bristles can increase the risk of tooth cracking. Hard bristles can be too abrasive for your teeth and cause micro-cracks in your enamel.

To prevent this, you should choose a Sonicare toothbrush with soft or medium bristles, as they provide sufficient cleaning power without causing unnecessary damage to your teeth.

You can also opt for a Sonicare toothbrush that offers different bristle options to suit your preferences and needs.

5. Use A High-Quality Electric Toothbrush

Not all electric toothbrushes are created equal. Some low-quality electric toothbrushes may have bristles or other components that are not designed to withstand the rigors of daily brushing. Using such toothbrushes can potentially lead to tooth cracking.

Therefore, it’s important to invest in a high-quality Sonicare toothbrush that is made with durable materials and has reliable performance. Choosing a reputable brand like Sonicare can ensure that you get a quality product that will last longer and protect your teeth from cracking.

6. Address Any Existing Dental Problems

If you already have dental issues like decay or weakened teeth, using an electric toothbrush like Sonicare may require extra caution. These dental problems can make your teeth more vulnerable to chipping, and the high-speed vibrations of a Sonicare toothbrush could worsen the situation.

If you have any existing dental problems, it’s important to consult with your dentist before using an electric toothbrush. Your dentist can advise you on the best toothbrush and brushing technique for your condition and help you prevent further damage.

How To Use Sonicare Toothbrushes Properly

For maximum effectiveness and prevention of tooth cracking, it’s important to use Sonicare toothbrushes properly. To get started with your Sonicare toothbrush, follow these simple instructions:

Before You Begin:

Press the brush head firmly into the handle, ensuring there is a slight space between the handle and the brush head. This is natural and important.

While Brushing Your Teeth:

  1. Wet the bristles of the brush head.
  2. Apply a pea-sized amount of toothpaste. Avoid using excessive toothpaste to prevent excessive foam and drips.
  3. Close your lips around the brush head and position the bristles towards the gum line at a 45° angle to avoid any splatter during cleaning.
  4. Press the power button to start brushing.
  5. Use gentle pressure and a slight back-and-forth motion to clean your teeth, allowing the brush to do the work.
  6. Continue brushing in this manner for the entire cycle.

After Brushing Your Teeth:

After use, rinse the bristles and brush head. Use a wet towel to clean the handle.

Now that you understand that Sonicare toothbrushes typically do not lead to tooth cracking unless misused let’s address some questions that will provide you with further clarity on the matter:

Can Electric Toothbrushes Cause Tooth Cracking?

In my opinion, the question of whether electric toothbrushes can cause tooth cracking is not a straightforward one. While it is true that electric toothbrushes do not directly harm teeth, it is important to note that they can potentially harm teeth indirectly if they are not used properly.

Is Sonicare too rough on teeth?

When used incorrectly, Sonicare may harm your teeth and gums due to the strength of the sonic waves. I’ve found that avoiding pressing too firmly or making sudden motions while using Sonicare is key. Using too much force can lead to gum recession and enamel erosion, so it’s important to let the toothbrush do its job with minimal pressure.

Is Sonicare too abrasive?

I can assure you that it is not. I have personally experienced the gentle yet effective cleaning power of the sensitive mode on the Philips Sonicare toothbrush. Extensive studies have shown that this innovative brush significantly minimizes dentin abrasion when compared to a manual toothbrush.


Sonicare toothbrushes are a great way to keep your teeth healthy and clean. They offer a superior brushing experience that removes more plaque and bacteria than manual toothbrushes. However, using a Sonicare toothbrush also comes with some risks.

If you are not careful, you may damage your teeth by causing cracks or fractures. By following the tips and techniques I’ve shared, you can fully enjoy the benefits of using a Sonicare toothbrush while minimizing the risk of tooth cracking.
