The Worlds First Red Light Therapy Tooth Brush
"It's like having professional treatment at home"
Tell us what's happening to you.
Your teeth look longer than they used to.
Gum recession is structural damage occurring 3 to 5mm below the surface — where your toothbrush, floss, and mouthwash physically cannot reach.
Every month you wait, more root is exposed. Sensitivity sharpens. And the window to avoid surgery gets smaller. A single gum graft runs $1,800 per tooth — and that's before the follow-up visits.
"I was quoted $3,800 for two grafts. After 8 weeks my dentist said my gums had actually firmed up. I cancelled the procedure." — Daniel R.
What Changes First:
- Recession begins to halt within 4–6 weeks
- Root sensitivity starts reducing as tissue repairs
- Avoids $1800+ graft surgery
Pink in the sink, every single morning.
Bleeding gums are not normal. They are a chronic infection signal from P. gingivalis — a bacteria research has linked to heart attack, stroke, and Alzheimer's disease.
Every time you brush and bleed, that bacteria enters your bloodstream. The longer it goes untreated, the deeper the damage spreads.
"By week 2 the bleeding basically stopped. By month 2 my dentist asked what I had changed." — Maria T.
What Changes First:
- Bleeding typically stops within 2 weeks
- Chronic infection cycle is broken at the source
- Bacteria entering your bloodstream is reduced
A warning at every single checkup.
When your dentist says it's getting worse, they mean the damage is progressing faster than your body can repair it. Standard cleaning removes surface buildup. It does nothing for the inflammation driving deterioration underneath.
Without treatment at the tissue level, the next visit will be worse than the last. Periodontal treatment at moderate stage averages $4,200 — and it doesn't reverse the damage already done.
"My periodontist said I was heading toward surgery. Three months later my pocket depths had actually improved. She wanted to know what I was doing." — Karen M.
What Changes First:
- Pocket depth improvement reported within 4 weeks
- Addresses deterioration between dental visits
- Measurable results at your next checkup
That electric jolt from one sip of cold water.
Sensitivity happens when receding gums expose the root of the tooth. The nerve sits completely unprotected. Every cold drink sends a signal directly into it.
Sensitive toothpaste coats the surface temporarily. It does nothing for the recession that caused the exposure in the first place.
"I had avoided cold drinks for two years. By week 4 I had an iced coffee for the first time without bracing myself." — James L.
What Changes First:
- Sensitivity relief reported within 3 weeks
- Treats root exposure not just surface symptoms
- Works where Sensodyne cannot reach

Find out what the professionals say about Dentra
Dr. Michael Reyes
General Dentist, DMD
"I've recommended photobiomodulation in-office for years. Dentra is the first home device I've seen that actually delivers the right wavelengths where it matters. My patients using it are coming back with less bleeding and reduced pocket depths. I recommend it now between cleanings."
Dr. Laura Bennett
Periodontist, DDS
"Sensodyne masks the symptom. Dentra addresses the cause. The 830nm near-infrared reaches the root exposure driving the sensitivity — no toothpaste does that. I've started recommending it to every patient who comes in asking why their sensitivity won't go away."
Dr. Ethan Cole
Periodontist, DDS
"Before I schedule a graft consultation I now ask if they've tried consistent photobiomodulation at home. The 660nm wavelength reduces the inflammation accelerating recession. Two patients in the last six months avoided the procedure entirely. At $139 it's the lowest-risk intervention I can suggest."
Melissa Grant
Dental Hygienist, RDH
"Most red light toothbrushes use one wavelength and call it therapy. The 460nm blue light targeting P. gingivalis — the bacteria driving chronic gum disease — is what makes this clinically meaningful. Red heals. Infrared repairs deep. Blue eliminates the source. That's a complete protocol in a toothbrush."
What 30 Days Can Do
With consistent twice-daily use, most users report noticeable reduction in bleeding, sensitivity, recession, and inflammation within the first 4 to 8 weeks. Individual results vary based on gum condition and consistency of use.
A Fresher, Cleaner Mouth
830nm near-infrared light penetrates deep to disrupt the bacteria responsible for bad breath at the source. Most users notice a cleaner, fresher mouth within the first few days.
Less Sensitivity. Less Bleeding.
660nm red light reduces gum inflammation and strengthens tissue through collagen synthesis. The two most common signs of gum disease — sensitivity and bleeding — typically ease significantly.
Your Dentist Notices
Healthier gums, reduced inflammation, and a visibly cleaner smile. Many customers report their hygienist asking what they've changed at their next appointment.

The most common questions from people with dental problems, answered.
A standard electric toothbrush only cleans the surface. Helios adds 660nm red and 830nm near-infrared light that works beneath the surface — reducing gum inflammation, supporting tissue repair, and targeting the bacteria that cause bad breath. It's the only daily-use device that combines both.
Most users notice a fresher, cleaner mouth within the first week. Sensitivity and bleeding typically reduce by days 7–14. By day 30, many customers report their dentist or hygienist commenting on the improvement at their next appointment
Yes. Both wavelengths are non-ionising and non-thermal at therapeutic levels. Dentra meets IEC 62471 photobiological safety standards. It is safe for daily use by adults.
No. Use it with your existing toothpaste and your normal brushing routine. For best results, add the 30-second gum treatment step after brushing — hold the brush head still against each gum area to maximise light exposure.
