No pain. No needle.
Dental anxiety is widespread, and fear of the needle is among the top reasons people delay or avoid care. The Henley multichannel dental device delivers anesthetic — and medication for periodontal disease — straight through the gum and into the tooth with a gentle current. No injection. Anesthesia in about four minutes.

The end of the dental needle
No needle, no fear
The single biggest source of dental anxiety is the injection. The device removes it entirely — the medication goes in through the surface.
Treats, not just numbs
The same delivery drives medicine into the tissue for periodontal disease — penetrating biofilm to treat, not just anesthetize.
Fast, localized, painless
Anesthesia in about four minutes, concentrated at the site — none of the whole-mouth numbness or the wait of an injection.
24 independent channels, no current tunneling
Single-electrode iontophoresis “tunnels” current through the path of least resistance, burning, and under-treating the rest. Henley’s patented multichannel electrode regulates each channel independently — so medication is delivered uniformly across the whole arch, tooth by tooth.
Validated, heading to clinic
Where it stands
Pre-clinically validated at the LSU School of Dentistry — gum tissue anesthetized with pulpal anesthesia on canine and premolars. Clinical trials planned for 2027, with a 510(k) submission built on the FDA-cleared Medion MI-200 predicate.
Who it’s for
General and pediatric dentistry, periodontal treatment, oral surgery — and any patient who avoids the chair because of the needle.
