Clear aligners have transformed orthodontic treatment in London, allowing patients to straighten their teeth discreetly without the need for metal brackets. However, to keep your aligners truly invisible and odour-free, proper cleaning and care are essential. Neglecting hygiene can lead to plaque build-up, unpleasant odours, and staining that makes aligners visible when you smile.
This detailed guide explains how to clean your aligners, prevent discolouration, and maintain excellent oral hygiene throughout your treatment.
Why Cleaning Your Aligners Matters
Clear aligners sit snugly over your teeth for 20–22 hours each day. Without regular cleaning, bacteria and plaque can accumulate, leading to bad breath, staining, and even tooth decay. When aligners are clean, your teeth appear brighter, and the trays remain crystal clear—ensuring your smile stays discreet throughout treatment.
The Right Daily Cleaning Routine
Morning and Night:
Start and end each day by rinsing your trays under lukewarm water. Use a soft toothbrush (kept only for aligners) and mild, clear soap to gently brush inside and outside. Avoid toothpaste—it’s abrasive and can scratch the plastic. After cleaning, rinse well and allow trays to air-dry before reinserting.
After Meals and Snacks:
Remove your aligners before eating or drinking anything except water. Brush your teeth or at least rinse your mouth before putting the trays back in. This prevents staining and keeps bacteria away from your teeth and aligners.
During the Day:
Keep a small aligner care kit with you—a toothbrush, toothpaste or mild soap, floss, and a ventilated case. London’s fast-paced lifestyle means you may eat out or grab coffee on the go, so having your kit handy ensures you can maintain hygiene wherever you are.
What to Avoid When Cleaning Aligners
Avoid using hot water, coloured mouthwash, bleach, or alcohol-based cleaners. These can warp or discolour the plastic. Do not use whitening toothpaste or baking soda, as they’re too abrasive and will make trays look cloudy over time.
Preventing Stains Before They Start
Most staining is caused by coffee, tea, red wine, curries, and soft drinks. Always remove your aligners when consuming these. Rinse your mouth and brush before reinserting the trays. This habit prevents pigments from transferring to both the teeth and aligners.
Since London water tends to be hard, always rinse aligners thoroughly and let them air-dry—this prevents mineral build-up that can dull their appearance.
Deep Cleaning Once a Week
In addition to daily cleaning, give your trays a deeper clean once or twice a week. Soak them in an aligner-safe cleaning solution for the recommended time to remove any stubborn residue or bacteria. Rinse thoroughly afterwards and avoid using any homemade mixtures that contain vinegar or hydrogen peroxide unless approved by your dentist. Ultrasonic cleaners can also help lift debris gently without damaging the trays.
Keep Your Teeth as Clean as Your Trays
Even clean aligners will stain if placed over unbrushed teeth. Brush twice daily with fluoride toothpaste and clean between your teeth using floss or interdental brushes. When eating out, carry travel-sized dental essentials to maintain freshness before putting your aligners back in.
If Your Trays Are Already Stained
If you notice yellowing or cloudy patches:
-
Gently brush them again using a clear, unscented soap.
-
Soak them briefly in a recommended aligner cleaning solution.
Avoid harsh scrubbing or using strong chemicals. If stains persist, contact your orthodontist—some aligner stages can be replaced if they’ve become too discoloured.
Safe Storage and Daily Habits
Always store your aligners in a ventilated case when not in use. Never wrap them in tissue or place them loosely in a pocket—they’re easy to lose or accidentally throw away. Keep an extra case in your bag, car, or at work so your aligners are always stored safely.
