How long does the device last?
HandySmile is rechargeable and built for long-term repeated use. Replacement whitening gel pens are available separately when needed, so you never need to replace the whole kit.
Is it waterproof?
Yes. HandySmile carries an IPX7 waterproof rating, meaning it can be fully submerged in up to one metre of water for 30 minutes. In practical terms, it can be thoroughly rinsed under running water after every use — an important hygiene advantage over water-resistant-only devices.
How long does each session take?
15 minutes. The device auto-times and switches off at the end of each session.
Why does HandySmile use 32 LED lights?
More LED beads means greater light coverage across the mouthpiece during each session. HandySmile's 32-LED design — 16 blue and 16 red — ensures all teeth receive consistent light exposure simultaneously, rather than patchy coverage from fewer lights.
How does the LED light work?
HandySmile uses dual LED technology — two wavelengths working together during every session. The blue LED (460±5nm) activates the whitening gel and accelerates the breakdown of surface stains for faster, more effective whitening. The red LED (620±5nm) supports gum health, aids tissue healing, and helps reduce sensitivity — making each session more comfortable, particularly for users with sensitive teeth.
What is the strength of the whitening gel?
HandySmile uses an 18% carbamide peroxide formula — the same class of whitening ingredient used in professional take-home systems prescribed by dentists. It delivers visible whitening results while remaining enamel-safe when used as directed. For context, 18% carbamide peroxide yields approximately 6–7% hydrogen peroxide as its active whitening agent, released gradually throughout the treatment session.
Can I use it while pregnant or breastfeeding?
We recommend avoiding the whitening gel during pregnancy or breastfeeding. However, the LED device can be used on its own — the red light therapy supports gum health and reduces inflammation without the gel. Always consult your healthcare provider before use.
How long does it take to see results?
Many customers notice a difference within the first few uses. For best results, consistent daily use over 7–14 days is recommended. Results vary depending on the level of existing staining and individual tooth structure.
How often should I use it?
Once a day, for 15 minutes per session. Consistent daily use delivers the best outcome.
Is it safe for enamel?
Yes. HandySmile uses an 18% carbamide peroxide formula that is enamel-safe when used as directed. Carbamide peroxide has been used in professional take-home whitening systems for decades and is widely regarded as one of the most trusted whitening ingredients available.
Does it cause sensitivity?
HandySmile is designed to be gentle. The gradual-release profile of carbamide peroxide means the whitening agent is delivered slowly over the treatment session rather than all at once — which many users find more comfortable than faster-acting hydrogen peroxide systems. The red LED light also supports gum health during treatment. Most customers experience little to no discomfort.
Can I use it if I have sensitive teeth?
Yes. The combination of carbamide peroxide's gradual release and the red LED wavelength makes HandySmile suitable for many users with sensitive teeth. If you have significant dental concerns, we recommend consulting your dentist before starting any whitening treatment.
Is it suitable for everyday use?
Yes, when used as directed. One 15-minute session per day is all you need.
