I'm A Dentist. Your Retainer Is Covered In 100 Million Bacteria Right Now.
I swabbed 20 patients' retainers under a microscope. Every single one was coated in a bacterial biofilm containing over 100 million microorganisms.
Streptococcus mutans. Candida albicans. Staphylococcus aureus. Living on the plastic they put back in their mouth 22 hours a day.
Every patient said: "But I clean it every day."
They do. Their method just doesn't work.
Water rinse: Removes food particles. Does nothing to biofilm. Zero percent of bacteria eliminated.
Toothbrush scrubbing: Creates micro-scratches on the surface. Those scratches become grooves where bacteria HIDE and multiply faster. Brushing makes the problem worse.
Polident/Retainer Brite tablets: Dissolves surface debris. But biofilm has layers — outer bacteria sacrifice themselves while the inner colony thrives. Like power-washing the outside of a building while mold grows in the walls.
Hydrogen peroxide: Dries out the plastic, makes it cloudy and brittle — while still failing to penetrate biofilm.
You invested $3,000-$7,000 in your teeth. You're protecting that investment with methods that leave 99% of bacteria untouched.
Bacteria form biofilm — a structured community held together by a sticky extracellular matrix specifically evolved to resist chemical penetration and mechanical disruption.
Your toothbrush operates at the macro level — way too large. Tablets work chemically at the surface — way too shallow.
To actually BREAK biofilm, you need:
1. Mechanical disruption at the microscopic level — physically tearing the matrix apart
2. DNA-level sterilization — destroying bacteria's ability to reproduce
What delivers both? The same technology dental offices have used for 40+ years: ultrasonic cavitation + UV-C light.
Ultrasonic cavitation generates sound waves at 48,000 cycles/second through liquid. These waves create millions of microscopic bubbles that form and implode — each implosion creating a tiny shockwave that tears apart biofilm at the molecular level.
It reaches every crevice no brush bristle or chemical can touch. The same principle used in hospital instrument sterilization.
UV-C light at 254nm destroys bacterial DNA on contact. Unlike chemicals (which bacteria develop resistance to), UV-C causes irreversible genetic damage. Bacteria can't reproduce. Can't survive.
Combined: ultrasonic breaks the structure, UV-C sterilizes the exposed bacteria. 99.9% elimination in under 5 minutes.
✅ 48kHz ultrasonic — higher than leading competitor's 42kHz
✅ 4 UV-C sterilization lights — 360° coverage at 254nm
✅ 200ml capacity — fits retainers, aligners, dentures, night guards, mouthguards, toothbrush heads
✅ Digital timer — 4 modes (3, 5, 8, 10 min)
✅ USB-C rechargeable — no counter clutter
✅ Chemical-free — just water. No tablets. No taste. No residue.
✅ Compact design — travel-friendly
Drop in. Add water. Press button. Five minutes. Done.
Your current routine: Take retainer out → rinse → scrub with toothbrush (scratching it) → drop in tablet → wait 15-30 minutes → rinse again → still feel a film → put it back and try not to think about it.
PureAlign routine: Take retainer out → drop in pod with water → press button → brush your teeth while you wait → remove retainer → crystal clear, odor-free, clinically sterile. Done in 5 minutes.
You save 25 minutes every day. That's 150+ hours per year on a cleaning routine that doesn't even work.
• Tablets: $15-20/month = $240/year. PureAlign replaces them permanently. Pays for itself in 5 months.
• One cavity: $150-300. PureAlign prevents the cause.
• Your orthodontic investment: $3,000-$7,000. Protected for $89.99.
• Cost per clean: $89.99 ÷ 730 cleans/year = $0.12.
60-day money-back guarantee. If your retainer isn't visibly cleaner, smells fresher, and feels smoother — full refund. Keep the device.
1-year warranty. Because clinical-grade devices deserve clinical-grade confidence.
The only question: how many more days do you want to put a bacteria-coated device back in your mouth?
Your Mouth Deserves Better Than Tablets.
PureAlign's 48kHz ultrasonic + UV-C sterilization destroys 99.9% of bacteria in 5 minutes flat.
No chemicals. No scrubbing. Just science.
