When the complete Glossonic Brush PRO + Glossonic Whitening Toothpaste system is used as directed, 460 nm blue light activates the PAP whitening formula as you brush. The brush head’s patented light-guiding technology helps direct blue light toward the tooth surface.

PAP (Phthalimidoperoxycaproic acid ) is a non-peroxide whitening agent. It breaks down stain molecules through oxidation but, unlike hydrogen peroxide or carbamide peroxide, it does not produce free radicals that can damage enamel or cause significant tooth sensitivity. Clinical studies show PAP delivers measurable whitening with minimal sensitivity, making it suitable for daily at-home use. PAP is the active whitening ingredient in Glossonic's whitening toothpaste, used together with our electric toothbrushes.

Yes. The blue light used in Glossonic Brush Pro operates at a wavelength and intensity that has passed photobiological safety testing. It is not UV light — it is visible blue light designed to activate the whitening agent and accelerate stain breakdown. The light intensity is calibrated to be effective for whitening while remaining well below safety thresholds for eyes and oral tissue. The device also features a pressure-sensitive button and shock-absorption structure to protect gums during brushing.

Most users see visible brightening within 2 weeks of consistent twice-daily use with the whitening toothpaste. In a 28-day external human clinical trial, subjects using the Glossonic Brush Pro + whitening toothpaste regimen achieved 4× brighter teeth compared to baseline, with statistically significant improvement as early as day 14. Individual results vary based on starting shade, diet (coffee, tea, red wine, tobacco), and consistency.

Yes. Bixdo whitening system uses PAP instead of peroxide, which is the primary cause of whitening-related tooth sensitivity. The Brush Pro also features a sensitive mode with reduced vibration intensity, and the bristles are made from rounded-tip imported Tynex filaments to minimize gum irritation. If you have severe sensitivity, start with the sensitive mode and gradually increase. For the Flosser Go, start with the lowest pressure setting.

Glossonic electric toothbrushes and water flossers are mechanical devices — they do not deliver drugs or chemicals into the body, so they are generally safe during pregnancy. The whitening toothpaste contains PAP, which is a topical agent that is not systemically absorbed in significant amounts. However, pregnancy can increase gum sensitivity (pregnancy gingivitis), so we recommend using the sensitive mode and consulting your dentist if you have specific concerns. We always advise checking with your healthcare provider for individual medical advice.

Glossonic Brush Pro has passed: CE (EU conformity), RoHS (restriction of hazardous substances), EMC (electromagnetic compatibility), EMF (electromagnetic field), WEEE (waste electrical and electronic equipment), IPX7 waterproof, GB 39669 (electric toothbrush safety standard), GB 4806 (food contact materials safety), and photobiological safety (IEC 62471) for the blue light. Clinical efficacy has been verified by third-party laboratories including human trials and in vitro tests.

The Glossonic Flosser Go is primarily a cleaning and gum health device, not a whitening device. It removes food debris and plaque from between teeth, which can prevent stains from forming and make teeth appear cleaner and brighter. However, it does not contain whitening agents (PAP or peroxide) and does not change the intrinsic color of teeth. For whitening, use the Glossonic Brush Pro with PAP whitening toothpaste. You can use warm water or a mild mouthwash in the Flosser Go for a fresher feel, but this will not whiten teeth.

Yes, and in fact a water flosser is often better for sensitive gums than string floss. The Flosser Go has 4 pressure settings — start with the lowest setting and gradually increase as your gums adapt. The pulsating water stream is gentler than the sawing motion of string floss, which can cut into sensitive gum tissue. If your gums bleed initially, this is common and usually improves within 1-2 weeks of consistent use. If bleeding persists beyond 2 weeks, consult a dentist.

You can add a small amount of alcohol-free mouthwash to the water for a fresher feeling, but we do not recommend using undiluted mouthwash or alcohol-based mouthwash as the sole fluid. Alcohol can dry out oral tissue and damage the device's internal seals over time. After using mouthwash in the tank, rinse the tank and internal tubing with clean water to prevent residue buildup. Do not use essential oil-based mouthwashes (like Listerine) undiluted, as they can degrade the device's materials.

Yes — a water flosser is highly recommended for people with braces. Orthodontic brackets and wires create numerous food traps that are difficult to clean with a toothbrush or string floss. The Flosser Go's pulsating water stream effectively removes food debris from around brackets, under wires, and between teeth. Use the orthodontic, or the standard tip with moderate pressure. Many orthodontists recommend water flossers as an essential cleaning tool for brace wearers.

Yes, you can use any toothpaste with Glossonic electric toothbrushes. However, for optimal whitening results, we recommend using Glossonic's PAP whitening toothpaste, which is formulated to work synergistically with the brush's sonic vibration and blue light technology. If you use a whitening toothpaste with peroxide, be aware that it may increase sensitivity. Avoid using extremely abrasive toothpastes (high RDA value) as they can wear enamel over time.
