For people whose gums are pulling back

Your electric toothbrush may be pushing your gumline back

The PRIMALS Horse Bristle Electric Toothbrush is the first natural bristle electric toothbrush, with ultra-soft bristles that flex with receding gums instead of scraping them.

Protect My Gumline With PRIMALS

Trusted by 1M+ people. Shared by 1,000+ clinicians.

🦷 What receding gums really means

Gum tissue doesn't grow back on its own

When your gumline pulls back, it exposes the root of the tooth. That root has no enamel covering it, which is why cold water suddenly stings and why your teeth start to look longer in the mirror.

The American Dental Association lists aggressive or excessive toothbrushing among the causes of gum recession.1 Most people hear that, switch to an electric toothbrush, and assume the problem is handled.

Switch To A Gentler Bristle
🧪 The part nobody tells you

A "soft" nylon head is still nylon

Nylon is a stiff plastic. A "soft" nylon head is still nylon, and on a sonic brush it hits the same spots along your gumline thousands of times a minute, twice a day, every day.

You changed the motor. You never changed the material touching your gums.

Ditch The Nylon Bristles
🔁 You already tried the usual fixes

You tried every fix. Your gums still pulled back.

  • 🪥What you've already triedYou bought the soft heads. You turned on sensitive mode. You got the brush with the pressure light. You switched to the sensitivity toothpaste. Your hygienist still measured more recession at your last visit.
  • 🧊What it feels like day to dayA zing from cold water. Pink in the sink. A tooth that looks a little longer every year.
  • 📋What's underneath itThe quiet dread before every checkup, because you know the number only moves one way.

📊 What it costs you over time

What recession costs you over time

  • 📈It's common58% of people 30 and older showed recession of 1mm or more in a US national health survey (Albandar and Kingman, Journal of Periodontology, 1999).2
  • 🦷Exposed roots are more vulnerableRoot surfaces are softer than enamel and more prone to sensitivity and root decay.
  • 🏥It's permanent without treatmentLost gum tissue usually needs a gum graft to restore, which is the procedure most people with recession are trying to avoid.
  • 🔬Nylon adds plastic to the mixPlastic toothbrushes shed 3,000+ microplastic particles per use, up to 2.3 million a year (Ecotoxicology and Environmental Safety, 2025).3
Figures are published research on plastic toothbrushes as a category. Nothing here is a claim that any toothbrush causes, treats, or reverses a health condition.

🐴 100% natural horse bristle

Change the bristle, keep the power

The PRIMALS Horse Bristle Electric Toothbrush is the first natural bristle electric toothbrush. 100% natural horse bristle, hand-woven into a glue-free bamboo head. Horse bristles are finer and more flexible than nylon, so they flex with your gums instead of scraping them.

Questions people with receding gums ask

Everything you might be wondering, answered plainly.

Will this reverse my gum recession?
No, and no toothbrush honestly can. Gum tissue doesn't grow back on its own. What you can change is what touches your gums twice a day. The PRIMALS Horse Electric uses the softest natural bristle for electric toothbrushes, so it flexes with your gums instead of scraping them. For recession that's already there, talk to your dentist or periodontist.
My gums are already sore. Is horse bristle soft enough?
Horse bristles are finer and more flexible than nylon. Start on Gum Care mode at the lowest intensity, use barely any pressure, and let the vibration do the work.
Does a softer bristle mean a weaker clean?
No. The motor still runs at 62,000 VPM and removes up to 10x more plaque than manual brushing. The bristle changed. The power didn't.
I have fillings, crowns, or implants. Does this matter?
Researchers measured small electric currents induced in metal dental work by the magnetic fields of standard electric toothbrushes, and noted those currents could cause pain or discomfort.4 We can't promise an outcome. We can tell you our magnetic field reading is about 11x lower than the leading plastic electric toothbrush on the same meter.
Is the PRIMALS Electric Toothbrush EMF-free?
No, and any motorized brush that says otherwise isn't being straight with you. Every motor produces a field. Ours is engineered for low EMF and measured 30x less electric field and 11x less magnetic field than the leading plastic electric toothbrush on the same meter. Lower, measured, published. Not zero.
Is it normal for a few bristles to come out?
Yes, in the first 1 to 2 weeks. A few bristles can shed early on as the bamboo head adjusts to your bathroom's humidity. That settles quickly.
Can I switch to a firmer bristle later?
Yes. The same handle takes PRIMALS Boar Bristle heads for a firmer clean. For receding or sensitive gums, horse is the one we'd start with.
What comes in the box, and how long does the battery last?
The brush, the wireless charging dock, and 2 horse bristle heads. Up to 365 days on a single charge, IPX7 waterproof, with a 2-year warranty and a 60-day guarantee. Autoship replacement heads are available.
