What is Red Light Toothbrush?
Dual Spectrum Therapy™
660nm red light suppresses the inflammatory cytokines driving gum breakdown. 830nm near-infrared penetrates 4–6mm into soft tissue — past the gumline, into the periodontal ligament where the destruction is actually occurring. Two wavelengths. Three targets. Simultaneously, every time you brush.
Reaches Where Nothing Else Can
Light penetrates 4–6mm below the gumline where no brush, floss, or mouthwash reaches. At this depth it disrupts the bacterial environment that causes bleeding, recession, and sensitivity — and begins the repair process from the inside out.
Results Without Surgery
Gum grafts cost $1,800 per tooth and weeks of soft-food recovery. Dentra addresses the root cause in 2 minutes a day — backed by a 90-day full money-back guarantee.
4 Precision Modes
Clean, Sensitive, Polish, and White — each calibrated for a different stage of your recovery. Because where you are in your gum health journey determines what intensity your tissue needs. Your oral health is supported no matter which you choose.
90 days of gum recovery
Not all electric brushes are equal.
Most toothbrushes clean the surface. Only one addresses what's happening beneath it.
