Busauruss

Busauruss uses nano-hydroxyapatite (nHAp) as its primary whitening agent — not hydrogen peroxide. nHAp is the same mineral that makes up 96% of your tooth enamel. It physically fills surface cracks and stain channels rather than chemically bleaching them, resulting in whiter teeth that don't rebound to their original shade as quickly as peroxide-whitened teeth do.

Most customers report visible improvement between Day 3 and Day 7 with twice-daily use. In our 312-participant clinical study, 89% of subjects showed measurable shade improvement by Day 7 using the Vita Classical shade guide. Maximum results typically peak between Day 14 and Day 30. Results depend on the starting shade of your teeth and dietary habits.

Busauruss is safe to use with all dental restorations. However, nHAp whitening — like all whitening agents — only affects natural tooth enamel, not the ceramic or composite materials used in crowns, veneers, or bonding. If your natural teeth whiten significantly, there may be a visible shade difference with restorations. We recommend consulting your dentist before use.

Unlike peroxide whitening (which typically fades in 4–8 weeks), nHAp remineralization provides structural whiteness that lasts 3–4 months before noticeable fading. Daily use maintains results continuously. Coffee, tea, wine, and tobacco will contribute to new staining. We recommend a Subscribe & Save plan for ongoing maintenance at 20% off retail.

Yes — Busauruss was specifically formulated for sensitive teeth. Our formula contains zero hydrogen or carbamide peroxide (the primary cause of whitening sensitivity), zero SLS, and contains 5% niacinamide which actively reduces dentinal hypersensitivity. In our clinical study, 94% of participants with pre-existing sensitivity reported improvement after 14 days of use.

We offer a 30-day, no-questions-asked money-back guarantee on all orders. If you're not 100% satisfied with your results within 30 days of delivery, simply contact us and we'll issue a full refund — including return shipping. We stand behind every tube we sell.
