Three simple steps to a clinically clean appliance.
Fill With Water
Fill a glass or your COJA Dental Pod PRO + UV with warm water — enough to fully submerge your appliance.
Submerge & Add Tablet
Place your appliance into the water, then drop in one COJA Cleansing Tablet. The activated oxygen formula goes to work instantly — soak for 5–30 minutes, or overnight for stubborn build-up.
Remove, Rinse & Wear
Remove your appliance, rinse thoroughly under running water, and dry before wearing. Fresh, clean, and ready to go — every single day.
Pro tip: Use COJA Cleansing Tablets inside your COJA Dental Pod for the most powerful clean. The ultrasonic vibrations combine with the active oxygen formula to remove even the toughest build-up in under 5 minutes. For appliances with stubborn stains, a gentle soft-bristle brush after soaking delivers the best results.

Our effervescent tablets release activated oxygen the moment they hit water — penetrating deep to break down plaque, bacteria, and odour at the molecular level. No bleach. No alcohol. No harsh chemicals.
Activated Oxygen Cleaning
Millions of micro-bubbles release on contact, reaching every groove and crevice a brush can't. Deep-clean action in minutes, not hours.
Breaks Down Tough Stains
Gently lifts plaque, tartar, and discolouration without abrasion. Your appliance comes out brighter — without a single scratch.
Kills 99.9% of Bacteria
Eliminates odour-causing bacteria and harmful microbes on contact. Clinically tested on all major oral appliance materials.
Fresh Mint Formula
A natural mint finish leaves appliances smelling clean and fresh — never chemical, never clinical. A scent you'll actually look forward to.
No Harsh Chemicals
Free from bleach, alcohol, and parabens. Safe for daily use on every type of oral appliance — aligners, retainers, dentures, and night guards.
Dentist Approved
Formulated with dental professionals and tested for compatibility with all major appliance materials — so you can clean with total confidence.
"I've tried every cleansing tablet on the market. Nothing compares to COJA. My aligners come out completely odor-free and visibly cleaner every single time."
"I was skeptical a tablet could do much but I was completely wrong. The effervescent action is satisfying and the mint scent is subtle and clean, not artificial."
"As someone with a retainer I've worn for 10 years, these tablets have genuinely changed my routine. Easy to travel with, no mess, and they actually work."
