Clear aligners are designed to be virtually invisible, giving you the confidence to smile freely while straightening your teeth. But if they’re not cleaned properly, they can quickly lose that crystal-clear look, becoming cloudy, stained, or even smelly. The good news is: keeping your aligners fresh is easy when you know the right steps.

In this guide, we’ll walk you through why cleaning is important, how to do it correctly, what to avoid, and some simple daily habits to make sure your aligners stay spotless.

Why Cleaning Your Aligners Matters

• Oral Hygiene: Plaque and bacteria build up on aligners the same way they do on teeth. Without cleaning, this leads to bad breath and potential cavities.

• Clarity & Confidence: Dirty aligners can become cloudy or yellow, making them visible when you smile.

• Comfort & Safety: Proper cleaning prevents bacteria and buildup that could irritate gums or cause infections.

• Treatment Success: Fresh aligners mean you’ll wear them as prescribed without hesitation—keeping your treatment on track.

Best Ways to Clean Your Clear Aligners

1. Rinse Every Time You Remove Them

Whenever you take your aligners out—for eating, drinking, or brushing—give them a quick rinse under lukewarm water. This prevents saliva and bacteria from drying on them.

2. Brush Gently Twice a Day

Use a soft-bristled toothbrush (separate from the one you use on your teeth) and clear, unscented antibacterial soap or aligner foam. Brush gently to avoid scratches, which can trap bacteria and make aligners look dull.

3. Soak Aligners Regularly

Soaking helps deep-clean your aligners. You can use:

• Aligner cleaning tablets (dissolved in water, usually 10–15 minutes).

• A solution of equal parts white vinegar and lukewarm water (rinse well after).

• Hydrogen peroxide mixed with water (mild solution, not full-strength).

Soak daily or every other day for the best results.

4. Clean Your Teeth Before Reinserting Aligners

Even if your aligners are clean, putting them back on after eating without brushing transfers food particles and bacteria inside. Always brush and floss before reinserting them.

What NOT to Do

• ❌ Don’t use toothpaste – it’s abrasive and will scratch the surface.

• ❌ Don’t use hot water – it can warp the plastic and ruin the fit.

• ❌ Don’t leave them unprotected – store them in their case when not in use to prevent bacteria and damage.

• ❌ Don’t soak in mouthwash – colored mouthwashes can stain aligners.
