Show Your Smile Off: Pro Tech's Smile Again is here to remove every last stain! This is the revamped version of our most effective cleaner, the ProTech Denture Cleaner. This is not a cleaner like other ordinary denture cleaning products: our competitors will give you effervescent bubbles and will bleach your denture until it appears to be clean, but in Pro Tech we want to give you truly clean dentures. That is why our formula will truly dissolve build up, calcium and calculus that can form over time on your denture, mouthguard, aligner or other oral prosthetic, while at the same time sanitizing for a truly clean result. Founded in 1983, ProTech Professional Products, Inc. is a leading manufacturer and distributor of quality dental laboratory and operatory supplies throughout the world. We take pride in being the "Experts in Dental Lab Products." It is our company's credo to make your buying experience, as informative and pleasurable as possible.
