Ask at the counter
Can I use the Feno® Smartbrush without the app?
Yes, the Feno® Smartbrush is fully functional on its own. The app simply adds extra features like tracking, coaching, and insights that help users get more out of every brushing session over time.
What are the ongoing costs after purchasing the Feno® Smartbrush?
The two main consumables to plan for are Feno® Foam toothpaste and a fresh TrueFit Mouthpiece recommended every three months. Feno® Plus subscription is optional and can be canceled anytime. Refills of Feno® Foam can be purchased one-off whenever needed or through subscription options.
Can I use the Feno® Smartbrush and Feno® Foam if I have sensitive teeth?
Yes! Both the Feno® Smartbrush and Feno® Foam are designed to be gentle for users with sensitive teeth. The Smartbrush features different speed levels letting you control the cleaning speed, while Feno® foam is formulated without harsh abrasives to provide an effective yet gentle clean. If you experience sensitivity, we recommend starting at the slowest speed and gradually adjust the speed to your comfort level. If you have any discomfort, please consult Feno® for personalized advice.
Can I use the Feno® Smartbrush™ if I have braces?
The Smartbrush is currently not designed to work with braces, but please stay tuned as we look to optimize the brushing experience for those with braces in the near future. When the day comes for your braces to be removed, the Smartbrush will be an excellent tool to help maintain your newly straightened and beautiful smile. We're excited to support your oral health journey, both now and in the future.
Can I use the Feno® Smartbrush if I have dental crowns?
The Feno® Smartbrush can be used with permanent dental crowns that have been in place for at least 4 weeks, but only with the lowest intensity setting. We do not recommend using the Smartbrush with temporary crowns, newly placed permanent crowns (less than 4 weeks), or if you have concerns about your specific dental work. As always, we recommend consulting your dentist before use if you have any dental restorations.
