The recommended method is to rinse the aligner under cool running water immediately after removal to prevent saliva and food debris from drying inside the tray. Use a soft-bristled toothbrush and a small amount of clear, unscented liquid soap to gently scrub the inner and outer surfaces. Pay particular attention to the gum line edge and any attachments seats (the small indentations that grip composite attachments on the teeth), as these accumulate the most biofilm. Rinse thoroughly before reinserting. Dedicated aligner cleaning crystals or tablets — such as those provided by Invisalign — can be used once daily as a deeper clean. Soak for the time specified on the product, then brush lightly and rinse before wearing. ## What NOT to use on clear aligners Several commonly available cleaning products will damage or discolour your aligners. Hot or warm water will warp the thermoplastic material — always use cool or lukewarm water. Regular fluoride toothpaste is mildly abrasive and will create microscopic scratches that trap bacteria and cloud the aligner over time — never brush aligners with toothpaste. Coloured mouthwash — such as blue or green formulations — will permanently stain the aligner material. Even clear mouthwash contains alcohol, which degrades the plastic with repeated use. Bleach-based cleaning products, dishwasher tablets, and boiling water are all damaging. Scented soaps can leave a residue that causes an unpleasant taste. Stick to clear unscented soap, cool water, a soft brush, and manufacturer-approved cleaning products only. ## Storing aligners safely when out Every clear aligner system comes with a hard plastic case — always use it when the aligners are out of your mouth. Aligners left on a table, wrapped in a tissue, or placed on a tray are the most commonly lost or accidentally discarded aligners. The case protects against both physical damage and contamination. If travelling, carry a spare case. Keep the case out of direct sunlight and away from heat sources such as car dashboards, which can warp the plastic even through the case. Store the previous aligner set in a labelled bag as a backup in case the current set is lost or damaged before the next appointment. Do not store aligners in their case while wet without first rinsing them, as a sealed damp environment encourages bacterial growth. ## Eating and drinking rules — what is actually safe Aligners must be removed before eating any food. Chewing with aligners in place can crack the plastic, distort the tray shape, or dislodge attachments — all of which interrupt treatment. Plain still water at room temperature or cool is safe to drink with aligners in and does not require removal. All other beverages — including hot drinks, fizzy drinks, fruit juice, squash, alcohol, and flavoured water — should be consumed only after removing the aligners. These liquids pool between the aligner and the enamel, creating an acidic or sugary environment that cannot be cleared by saliva, significantly increasing the risk of decay. After eating or drinking anything other than water, rinse your mouth and ideally brush before reinserting the aligner to avoid trapping debris against the teeth. ## Travelling with aligners When travelling, carry the aligner case, a travel toothbrush, and aligner cleaning tablets in hand luggage rather than checked bags in case luggage is delayed. Keep the previous set of aligners in your bag as a backup. If you are crossing time zones, maintain the 20 to 22 hours per day wear requirement and use the number of days worn rather than calendar dates to track when to progress to the next aligner. If flying, drink water regularly as cabin air is very dry and can make the aligners feel tight — do not remove them for the duration of the flight unless you are eating. If your orthodontist is using remote monitoring via a scanning app, check in as normal during your trip. ## Signs an aligner is damaged and needs replacing Hairline cracks along the edge of an aligner can expand with wear and cause the aligner to split. A rough or sharp edge that was not present when the aligner was first fitted may indicate the plastic has cracked. If an aligner no longer seats fully on the teeth despite good compliance and feels loose or sits proud at the gum line, it may have distorted. Significant discolouration that persists after cleaning is cosmetic rather than clinical but worth flagging. Any visible crack, split, or distortion that affects how the aligner fits should be reported to your orthodontist promptly. Wearing a damaged aligner that does not fit correctly will not move teeth in the intended direction and will waste treatment time. Your orthodontist will advise whether to wear the previous set, the next set, or to order a replacement. ## Lost aligner steps If you lose an Invisalign or clear aligner tray, contact your provider quickly and keep wearing an aligner unless told otherwise. In many cases the previous aligner is used to hold the teeth while the clinician decides whether to order a replacement tray or move you forward. Do not skip several trays or leave the teeth without an aligner, because even a short gap can allow relapse and make the next tray harder to seat. Ask whether replacement aligners are included in your package or charged separately. ## Useful related pages [Clear Aligner Compliance UK](https://virtualconsultant.online/guides/clear-aligner-compliance-uk) [Best Clear Aligners UK](https://virtualconsultant.online/guides/best-clear-aligners-uk) [How to Clean Braces UK](https://virtualconsultant.online/guides/how-to-clean-braces-uk) [Orthodontic Emergencies UK](https://virtualconsultant.online/guides/orthodontic-emergencies-uk) [Get a Free Virtual Consultation](https://virtualconsultant.online/evaluations/quote) This guide is for general information only.

No. Coffee should always be consumed with aligners removed. Coffee is hot — which risks warping the aligner — and is strongly pigmented, meaning it will stain the plastic within days. Coffee also promotes bacterial growth when trapped between the aligner and enamel. Remove the aligner, drink your coffee, rinse your mouth, and reinsert. If you are frequently removing aligners for hot drinks, set a timer to ensure you are still achieving 20 to 22 hours of wear per day. How often should I clean my aligners? At minimum, clean your aligners every time you brush your teeth — morning and evening. Ideally, rinse them under cool water every time you remove them to eat or drink. A deeper clean with aligner cleaning crystals or a dilute retainer cleaning tablet once daily helps prevent biofilm build-up and keeps the aligners clear. Do not let aligners sit in a dry case for extended periods without cleaning them first. Can I use denture cleaner on my clear aligners? Some denture cleaning tablets are safe to use on clear aligners, but not all. Effervescent denture cleaners that are clear when dissolved are generally acceptable for short soaks (10 to 15 minutes). Avoid denture cleaners with bleaching agents or strong colouring as these can affect the plastic. Dedicated aligner cleaning products — such as Invisalign cleaning crystals or Retainer Brite — are preferable as they are formulated specifically for the thermoplastic material aligners are made from. Always check with your orthodontist if unsure. What happens if I lose an aligner? Contact your orthodontist as soon as possible. In the meantime, wear your previous aligner set to maintain tooth position and prevent regression — do not leave your teeth without any aligner in place. Your orthodontist will advise whether to order a replacement of the lost aligner or to progress to the next aligner in the sequence depending on how far into the wear period you were. Most clear aligner systems allow replacement aligners to be ordered, though this may incur a fee and cause a delay to your overall treatment timeline. Can I skip to the next aligner if I lost one? Only if your clinician advises it. Skipping ahead can work in some cases near the end of a tray's wear period, but it can also create tracking problems if the teeth are not ready. Wear the previous aligner and contact your provider for instructions. How do I stop my aligners smelling? Aligner odour is almost always caused by insufficient cleaning. Bacteria and food debris build up in the tray, particularly around the gum line and attachment seats. Cleaning aligners with clear unscented soap and a soft brush after every meal, rinsing before reinsertion, and using aligner cleaning tablets daily will eliminate odour in most cases. Ensure you are also brushing and flossing your teeth before reinserting aligners, as bacteria on the teeth transfer to the tray. If odour persists despite thorough cleaning, mention it at your next appointment as it may indicate a dental hygiene issue that needs addressing independently. Can I clean aligners with toothpaste? No. Toothpaste — including sensitive and whitening formulations — contains mild abrasives that scratch the aligner surface. These scratches are not visible to the naked eye but create a rough surface that harbours bacteria, makes the aligners appear cloudy faster, and reduces their optical clarity. Always use a clear, unscented liquid soap and a soft toothbrush instead. Some people use a small drop of washing-up liquid as an alternative — this is acceptable provided it is uncoloured and thoroughly rinsed off before wearing.
