How Do I Clean Invisalign Trays?

What You'll Learn

The most effective routine is simple: rinse your aligners every time you take them out, and give them a thorough clean at least once a day. Use a soft-bristled toothbrush — not your regular toothbrush, which may have toothpaste residue — and a small drop of clear, unscented dish soap. Gently scrub the inside and outside of both trays, paying attention to the ridges and edges where bacteria accumulate. Rinse thoroughly with lukewarm water before reinserting.

Invisalign cleaning crystals are specifically formulated for aligner trays and are a reliable choice. Retainer cleaning tablets (such as Retainer Brite or Efferdent) work equally well and are widely available. Soak the aligners for the time specified on the package, then rinse thoroughly. Clear, unscented dish soap is the most accessible everyday option and is safe for daily use. All of these options keep aligners clear and odor-free without damaging the plastic.

Never use hot water — it warps the aligner plastic and can permanently alter the fit. Avoid colored or scented soaps, which can stain or leave residue. Do not use regular toothpaste, which is abrasive enough to scratch the surface and make aligners look cloudy. Avoid colored mouthwash for the same reason. Do not soak aligners in bleach or alcohol-based solutions, as these degrade the plastic over time.

Your aligner case is just as important as the aligners themselves. Rinse it daily and let it air dry completely before closing it. A damp, closed case is an ideal environment for bacteria and mold. Replace your case every few months or whenever it develops an odor or visible discoloration. Keeping a clean case means your freshly cleaned aligners stay clean until you put them back in.
