Have you heard the latest “buzz” in the powered toothbrush market?
Actually, “hum” is a better word to describe the sound, and it’s coming from the direction of Colgate, which introduced a new electric toothbrush on Monday, August 17, 2020.
The hum toothbrush (“hum” is spelled entirely in lowercase) is available to purchase online directly from Colgate.
What Is hum?
hum is the new smart powered toothbrush by Colgate. More than just a toothbrush with vibrating bristles, hum helps users track their brushing habits, including the frequency, duration, and coverage pattern of their brushing. The brush syncs with the hum by Colgate app to help people keep track of their brushing data and get personalized recommendations for improving their brushing routine.
The hum toothbrush is more than just a new gadget to make tooth brushing fun. It’s a whole new lifestyle tool.
Why Did Colgate Make the hum Toothbrush?
Colgate is already a leader in toothbrush sales in the United States. But the company wanted to respond to the need for an accessible smart brush that helps more people improve their oral hygiene habits.
So the hum toothbrush delivers two benefits: it cleans teeth with sonic vibrations and it teaches people to brush better. Using hum daily will give the users more insight into the way they brush their teeth, remind them to brush regularly, and alert them to areas where they need to make improvements.
What Makes the hum by Colgate Toothbrush Special?
There are already dozens of electric toothbrushes on the market and they come in a massive spectrum of price ranges and features.
What makes Colgate’s new hum toothbrush stand out as the one worth trying?
Let’s look at the specs.
The hum smart toothbrush
One thing that makes hum unique is that it has both replaceable and rechargeable battery models. You can enjoy the same new hum toothbrush technology in the toothbrush model of your preference. Both brushes use the same brush heads which you can purchase through hum’s brush head subscription plan.


hum smart brushing technology
The hum toothbrush has smart sensors built into it that store and transmits data about how you use the brush. This toothbrush can tell what spots in your mouth you’ve finished brushing and which areas you need to spend more time on and shows you this data on an app.
hum’s different power modes
Like most other electric toothbrushes, hum offers various brushing modes to let you customize your experience.
The rechargeable hum brush comes with three rushing modes:
- Normal
- Sensitive
- Deep clean
The brush model powered by replaceable AAA batteries offers two brushing modes:
- Normal
- Sensitive
An ergonomic design
A hum brush will look good on your bathroom sink and feel beautiful in your hand.
The brush handle on the hum has an ergonomic design to make it feel comfortable to the touch and easy to maneuver in the mouth. Its base is round and flat so that it can stand up on end on a flat surface.
The hum brush sports a soft matte finish and comes in three cool pastel shades of blue, green, and purple. The design is visually appealing, clean, and soothing.
hum toothbrush head subscription
The brush heads for hum brushes are small with a slightly rounded arrangement of soft bristles. The hum is a vibrating toothbrush, not an oscillating one, so the bristles aren’t in a perfect circle.
The brush head’s size promises a thorough cleaning experience since it’s easier to access more tooth surfaces with a minimal head like that. The brush heads also have rubber cups for extra polishing power and a tongue cleaner for added freshness.


When you purchase a hum brush, it includes a brush head to get you started. You can subscribe to the toothbrush head replacement service at the time of purchase and enjoy your first toothbrush head replacement for free. After that, you’ll be automatically billed $4.99 every three months for a replacement head.
Eventually, you will be able to make a one-time purchase of replacement heads and subscribe to the hum brush head subscription service anytime you wish. For now, though, the only way to subscribe is by signing up at checkout when you purchase a hum brush.
The hum by Colgate app
Many people enjoy tracking and monitoring their health with smartphone apps. Colgate is leveraging this trend by offering app integration with the hum toothbrush.
The hum by Colgate app is free on the Apple Store and on the Google Play Store.
The company designed the hum by Colgate app to work with the hum brush to track brushing data and make recommendations.
Simply download the app onto your smartphone, connect it to your hum brush via Bluetooth, and enjoy a comprehensive brushing experience like no other.
While you brush the app will:
- Show you which areas in your mouth you have completed and which are left.
- Keep track of the amount of time you spend brushing.
- Encourage you to brush longer or to spend more time brushing certain teeth.
Based on your brushing data, the app will generate customized recommendations and brushing programs to help you set and reach new goals for improving your oral health and hygiene.



An exciting feature of the hum by Colgate app is that you don’t need to have it open every time you brush. Your toothbrush will store your brushing data locally for up to ten days, and then you can sync it with the app.
You can also use the app’s reward system to motivate yourself to reach your brushing goals.
If you use Apple® Health, you can opt to save your hum brushing data there.
The rechargeable hum toothbrush vs. the battery-powered hum toothbrush
hum technology comes in two accessible modes: a rechargeable electric hum toothbrush and a battery-powered hum toothbrush. Both brushes have the same capacity to monitor your brushing activity and integrate with the hum by Colgate app to analyze
While the technology behind the brushes is the same, there are some key differences between these two new Colgate toothbrushes.
Rechargeable Electric hum Toothbrush
- Charges via the included charger
- Toothbrush handle is one solid color and does not open up.
- Offers 3 brushing modes
Battery Powered hum toothbrush
- Requires two replaceable AAA batteries
- Toothbrush handle is dual-toned with a darker color on the end that unscrews open for access to the battery compartment.
- Has only 2 brushing modes
Other than those differences mentioned above, the two hum brushes work in the same way. Both include built-in timers to encourage you to brush for the recommended two-minute minimum, and both can help you track and transform your brushing habits.
So, in this case, there’s no need to compare the functionality of these brushes. You can choose either and still have a great brushing experience. The rechargeable brush can save you money on batteries in the long run, but the battery-powered hum will be useful for travel, camping, and other situations where you may not have regular access to electricity.
The price of hum by Colgate
So how much does this fantastic new brush cost? The Colgate hum website lists the rechargeable electric hum toothbrush at $69.99, and the hum model that runs on replaceable AAA batteries costs $49.99.
As mentioned earlier, a replacement brush head costs $4.99, and you can receive a new one every three months by subscribing when you order a hum toothbrush.
hum’s price positions it squarely as a mid-range electric toothbrush. It offers plenty of value, but the price is low enough that many people will be able to afford it.
For your peace of mind, Colgate offers a 30-day money-back guarantee if the hum toothbrush doesn’t live up to your expectations.
The New hum Toothbrush by Colgate: In Summary
This new brush might look like just another hopeful in the ever-growing market of electric toothbrushes, but hum holds out something extra.
The hum is a powered toothbrush that makes app integration technology accessible to more people. Its reasonable price tag means that more people can afford to try “smart brushing” and benefit from analyzing the data on their brushing habits.
Folks will also appreciate the fact that they can try this new technology by using either a replaceable or rechargeable battery model, per their preference.
Colgate is a trusted and popular brand with an extensive marketing reach, so the brush will probably perform well.

We’re excited to see how the hum by Colgate will be received! It’s already scored many positive reviews from their crowd of product testers, and there will be many more to come as people purchase the brush and try it for themselves.
The hum toothbrush is not some gimmicky new toothbrush that buzzes and lights up. It has a lot of promise as a useful tool that pairs tech with dental health awareness.
The hum by Colgate has excellent potential, and we believe it’s worth checking out.
