Proper manual brushing is excellent — most people just don't do it consistently. With Feno, all 18,000 bristles contact every tooth at once, so you're not chasing coverage one quadrant at a time. You still move it in a circular motion through the cycle, but the hard parts — correct angle, reaching the back molars, not missing the same spots every day — are handled by the fit. Less technique to get right.

Yes, with disclosure. Tell patients about the financial relationship, only recommend it where it genuinely fits, and check your state board's rules on in-office sales. We'll provide whatever documentation you need.

Established crowns, implants, veneers, bridges and fillings are fine — soft nylon bristles, gentle sonic motion. For a newly placed crown, wait 4 weeks before using Feno. Removable appliances — clear aligners, retainers, partials, dentures — should be taken out before brushing. Fixed braces are a no.

Feno Foam is xylitol-based and fluoride-free, formulated for even coverage with the mouthpiece. It isn't a fluoride substitute — if a patient uses or needs fluoride, keep it in the routine.
