BeamBrush + charging base
Red + Near-Infrared Light, Built Into a Toothbrush
The Canker Sore ReliefThat Doesn't Involve Burning Anything
Hold SpotBeam™ on the sore for 60 seconds. No cautery swab, no numbing gel that wears off, no waiting it out. Also eases the raw spots braces and clear aligners leave behind.
Is this just another red-light gadget that won't do anything?
Fair question — a lot of them don't. Most general red-light panels and wands aren't built for sustained, direct contact inside the mouth, and rarely say what wavelength or dose actually reaches the tissue. beambrush’s head is designed to sit flush against one spot for a fixed 60-second session at a stated wavelength — not just "red light somewhere near your face." And you get 90 nights to decide it isn't working for you.
If You're Here, You Already Know
You're not imagining how much this hurts.
- 1A canker sore shows up, and suddenly eating, talking, even smiling sideways is off the table for a week.
- 2Someone says "oh, it's just a little bite" — and you smile and don't bother explaining.
- 3The stuff that's supposed to actually work — a swab, a pinch of salt, an unlit match — hurts worse for thirty seconds than the sore did all day.
- 4Your braces or clear aligners rub a new sore into your cheek the same week the last one finally closed.
- 5You've tried the toothpaste swap, the vitamins, the salt rinses. Some weeks it helps. Most weeks it's a shrug.
None of that is in your head. Nobody's built much for the in-between — something that isn't a chemical burn, and isn't a wish.
The Mechanism
Light, not chemicals.
Every BeamBrush has a second mode. Turn it on, and the sonic motor goes quiet — the two wavelengths of light stay on, held steady against the one spot that hurts.
Feel it starting
A tingle, a bite, a new rub spot from your wire or a fresh aligner tray. Catch it early if you can — it isn't required.
Hold SpotBeam™ for 60 seconds
660nm red + 830nm near-infrared light, aimed directly at the tissue. No brushing motion, no toothpaste — just light, held still.
Go back to your day
Repeat 2–3 times a day while it runs its course. The same brush handles your regular morning and night routine too.
Why Two Wavelengths
Red reaches the surface. Near-infrared goes deeper.
660nm red light works on the visible surface of the tissue. 830nm near-infrared is invisible to the eye but travels further into soft tissue — the two are usually studied together, not as substitutes for each other. SpotBeam™ runs both at once, every session.
The Honest Comparison
BeamBrush vs. what you're probably doing right now.
| BeamBrush | Cautery Swab (Debacterol-type) |
Numbing Gel | Salt / DIY | |
|---|---|---|---|---|
| No burning or chemical sting | ✓ | ✗ | Masks pain only | ✗ |
| No prescription needed | ✓ | Often Rx | ✓ | ✓ |
| Also eases braces & aligner sore spots | ✓ | ✗ | Temporary | ✗ |
| Reusable — not single-use | ✓ | One swab, gone | Tube runs out | ✓ |
| Something you already reach for daily | ✓ It's your toothbrush | ✗ | ✗ | ✗ |
Not Just for Canker Sores
Also for the weeks wax can't fix.
Wires poke. Attachments scrape. A fresh set of aligner trays turns the inside of your mouth into a work in progress for the first day or two — every single time you switch. Wax helps until it doesn't stay put. SpotBeam™ goes directly on the sore spot for 60 seconds, no dental-office trip required.
Why Light, Not Chemicals
This isn't a wellness trend. It's guideline-level medicine.
Doctors call this oral mucositis. Everyone else just calls it "my mouth sores."
Red and near-infrared light on soft tissue in the mouth has been studied since the 1960s — but the strongest recent evidence didn't come from a supplement brand. It came from international cancer-care guidelines. In 2019–2020, the body that sets supportive-care standards for cancer treatment (MASCC/ISOO) gave this category of light therapy — LED-based devices included, not only lasers — its full recommendation for preventing severe mouth sores during radiation treatment. That's the strongest recommendation this kind of therapy has ever received.
Of every intervention tested for preventing severe chemo- and radiation-related mouth sores, light therapy was the only one shown to measurably reduce the risk.
Multiple published reviews on light therapy for everyday aphthous ulcers (canker sores) found consistent reductions in pain and shorter healing time — in 14 of 21 underlying studies, a single session was enough to see an effect.
Studies on light therapy after adjustments and new aligner trays found reduced pain in the first 24–72 hours, though results here were more mixed than the mouth-sore research above.
A CE-marked home-use LED device for oral mucositis (650–660nm, roughly 28 mW/cm²) is the closest published real-world benchmark for a consumer device like this one — not a lab laser.
*The clinical research cited above is on red and near-infrared light therapy for mouth-tissue conditions generally — it is not a study of the BeamBrush specifically, and individual results vary. This device has not been studied in, and is not intended for, people undergoing active cancer treatment. If you are undergoing cancer treatment, are pregnant, or have a diagnosed autoimmune condition causing your mouth sores, talk to your doctor before use. Not a replacement for professional dental or medical care.
What To Actually Do
What to do when one shows up.
Start a spot session
Hold SpotBeam™ directly on the area for 60 seconds, as soon as you notice it. Earlier is better, but it's not required.
Repeat 2–3× daily
Keep using your normal toothpaste and routine alongside it. Nothing else about your day needs to change.
It's just your toothbrush
Charge it on the counter, use it every morning and night — so it's already in your hand the next time you need it.
90 nights. If it hasn't changed your relationship with mouth sores, send it back.
Full refund, no photos or forms required. We'd rather you tell us it didn't work than keep something that didn't.
Why We Built This
"We went looking for why nobody had made a canker-sore product that doesn't hurt to use. What we found: the strongest published evidence for light therapy on mouth tissue comes from guideline-level cancer-care research — not a wellness fad. And yet every canker-sore product on the shelf still works by burning, numbing, or hoping. So we built a toothbrush with a second mode: light, held steady, on the spot that actually hurts."— The beambrush team
Questions
Things people actually ask.
Is this going to hurt like Debacterol or a cautery swab?
No. There's no acid, and nothing is burned or sealed shut. SpotBeam™ is light, held against the tissue — what you feel is gentle warmth, not a sting.
How is this different from the red-light gadgets and panels I've seen?
Most general red-light devices aren't built for direct, sustained contact inside the mouth, and don't specify what actually reaches the tissue. beambrush’s head is designed to sit flush against one spot for a fixed 60-second session at a stated wavelength — not just "red light somewhere near your face."
Can I use it with braces or clear aligners?
Yes. The head is small enough to reach behind wires and around attachments for wire pokes, bracket rubs, and the first uncomfortable days of a new tray.
Will it help a bitten cheek or a burn from hot food?
It's gentle enough for everyday minor mouth irritation generally, not only recurring canker sores — though it isn't a treatment for anything beyond that.
Is it safe to use every day?
Yes. Red and near-infrared light at the levels used here is non-thermal and non-ionizing. Every unit is tested against IEC 62471 photobiological safety guidelines before it ships.
Is it safe during pregnancy, cancer treatment, or with an autoimmune condition?
Talk to your doctor first. We haven't studied this device in those situations, and want you to check before adding anything new to your routine.
What is oral mucositis, exactly?
It's the clinical name for inflamed, often ulcerated tissue inside the mouth — the umbrella term that includes everyday canker sores as well as the more severe mouth sores some people get during cancer treatment. You've almost certainly heard it called "mouth sores" or "canker sores" instead.
What if it doesn't work for me?
90 nights to find out. Full refund, no photos or forms required.
Do I need to change my toothpaste or routine?
No — use it exactly like your current toothbrush. Add the 60-second SpotBeam™ session only when you actually have a sore spot.
Ready When You Are
Keep it by the sink. Use the light the next time it starts.
