SAVE 45%: Brush your way to a brighter smile with the hum by Colgate Smart Sonic Toothbrush, which is on sale for just $19.99 at Walmart as of Feb. 11. That's $16 in savings.

In your quest for a clean mouth and brighter smile, it's hard to measure your results. But with a smart toothbrush, you can connect to a compatible app that lets you know your strengths and shortcomings when it comes to oral hygiene.

As of Feb. 11, the hum by Colgate Smart Battery Toothbrush Kit is on sale for $19.99 at both Walmart and Amazon. That's 45% off and $16 in savings.

The hum toothbrush comes in both rechargeable and battery-powered versions. This deal is only available on the battery-powered option, but you'll still get the powerful vibrations, two-minute timer, stylish matte design, and three colors (turquoise, pastel blue, and purple) to choose from.

The toothbrush itself has two vibration modes (normal and sensitive) an ergonomic handle, and smart sensors that gather data as you brush.

The hum app is where things get interesting. It shows you a virtual jaw and follows along with your brushing in real time, marking which areas are clean and which remain untouched. It also tracks the time spent brushing, details on your speed, angle, and accuracy, and even offers personalized pieces of advice. You'll even get points and rewards, like extra brush heads, to stay motivated. The more you brush with the hum, the more your brush (and the app) get to know you and your habits, helping you improve your oral hygiene overall.
