Pumice
Free!
Dental Pumice is a fine volcanic powder used as a mild abrasive for cleaning and pre-polishing teeth, dentures, and metal/acrylic appliances. Mixed with water, it quickly removes stains and surface residues without scratching, setting up a smooth base for final shine. Available in multiple grades, it’s economical, easy to rinse, and ideal for daily lab work or chairside preparation before bonding or finishing.
Description
Dental Pumice is a finely ground, volcanic mineral powder used as a mild abrasive for cleaning and polishing in the lab and clinic. Mixed with water to form a slurry, it removes surface stains, investment residues, and minor scratches without gouging enamel, acrylic, or metal. Because pumice is inert and silica-based, it delivers consistent, controllable cut and a matte pre-polish that prepares surfaces for high-shine finishing pastes.
Key features and benefits:
• Gentle, controllable abrasion for predictable surface smoothing
• Works on enamel, acrylic dentures, orthodontic appliances, and cast alloys
• Available in fine, medium, and coarse grades to match the task
• Water-mixable slurry reduces dust and heat build-up
• Economical for daily use; easy to rinse away and leaves no oily film
Common use cases:
• Pre-polishing acrylic dentures and removable appliances prior to final gloss compounds
• Removing chairside stains and plaque from teeth or appliances before bonding or sealant placement (use plain, oil-free pumice)
• Cleaning castings after devesting and smoothing minor investment remnants
• Refreshing thermoformed retainers and mouthguards without distorting edges
How it compares:
• Versus polishing pastes: pumice cuts faster for initial cleanup and scratch removal; pastes are better for final luster.
• Versus aluminum oxide: pumice is milder and more forgiving, ideal for broader cleanup and pre-polish stages.
• Versus rubber wheels alone: pumice reaches contours uniformly and minimizes heat, then wheels or pastes bring up the shine.
Handling guidance:
• Mix with water to a creamy slurry; adjust viscosity for the desired cut.
• Use clean cups or bowls and fresh batches to reduce cross-contamination.
• Rinse thoroughly and follow with finer abrasives or polishing compounds as needed.
• Standard lab hygiene applies; avoid breathing dry powder and keep work areas damp-wiped.
Dental Pumice is a dependable, multi-purpose abrasive that streamlines cleanup, improves polish quality, and supports consistent results across prosthodontic, orthodontic, and general practice procedures.
