Clear aligners are popular because they are nearly invisible and easy to remove. But because you wear them for most of the day, they also collect saliva, plaque and food particles. If they are not cleaned well, they can turn cloudy, start to smell, and even affect your teeth and gums.
The good news is that caring for aligners takes only a few minutes a day. This guide explains how to clean clear aligners properly, what to avoid, and when to contact your dentist.
Why Is Cleaning Clear Aligners So Important?
Clean aligners help keep your teeth, gums and breath healthy during treatment. Aligners fit tightly over your teeth. When plaque or food gets trapped underneath, it stays pressed against the teeth for hours, with less saliva reaching the area to wash it away.
Poor aligner hygiene may lead to:
- Bad breath and an unpleasant taste
- Cloudy or stained trays that look less clear
- Plaque buildup, which raises the risk of cavities
- Gum irritation or bleeding
How to Clean Clear Aligners Every Day
Rinse your aligners every time you remove them, and give them a gentle brush at least once or twice a day. Here is a simple routine most patients can follow, unless your dentist advises otherwise.
1. Rinse every time you take them out
Rinse the trays under cool or lukewarm running water as soon as you remove them. This washes away saliva before it dries and leaves a white film.
2. Brush gently with a soft toothbrush
Use a separate soft toothbrush only for your aligners. Brush the inside and outside of each tray gently. A small drop of mild, clear, unscented liquid soap can help. Rinse well so no soap taste remains.
3. Soak them if your dentist recommends it
Some dentists suggest soaking aligners in a cleaning solution or cleaning crystals made for aligners. Follow the product instructions and your dentist’s advice about how often to soak.
4. Brush and floss before putting them back
Always brush your teeth, and floss if possible, before placing the aligners back in. Otherwise, food particles get trapped between your teeth and the trays.
5. Store them in their case
When the aligners are not in your mouth, keep them in their case. Wash the case regularly with soap and water and let it air dry.
What Should You Avoid When Cleaning Aligners?
Avoid heat, harsh chemicals and anything abrasive, as these can damage or warp the plastic. Aligners are made to fit your teeth very precisely, so even small changes in shape can affect how well they work.
- Hot or boiling water: Heat can warp the trays and change their fit.
- Regular toothpaste: Many toothpastes are mildly abrasive and can leave tiny scratches that trap stains and bacteria.
- Coloured mouthwash or soap: These may stain the trays.
- Bleach, alcohol or strong cleaners: These can damage the plastic and are not safe for your mouth.
- Wrapping aligners in tissue: They are easy to throw away by mistake.
If you are unsure about a cleaning product, check with your dentist before using it.
What Can You Eat and Drink With Aligners On?
Plain water is generally the only drink to have while wearing aligners. For everything else, take them out first.
Tea, coffee, soft drinks and juices can seep under the trays. Sugary or acidic drinks then stay against your teeth for longer, which may increase the risk of decay. Tea and coffee can also stain the trays.
After eating or drinking anything other than water, brush your teeth or at least rinse your mouth well before putting the aligners back. When you go out, carry a travel toothbrush and your case.
How Long Should You Wear Your Aligners Each Day?
Aligners only work while they are in your mouth. At Smilessence Dental Clinic, patients are generally advised to wear each set for about 20 to 22 hours a day, removing them only to eat, drink and brush. Your dentist will tell you exactly how long to wear each tray, as this depends on your treatment plan.
Frequent snacking means more removals and less wear time, so try to stick to meal times.

When Should You Contact Your Dentist?
Mild pressure for a few days after switching to a new set is common. However, contact your dentist if you notice:
- A crack, chip or sharp edge on the aligner
- Aligners that no longer fit snugly or feel loose
- A lost or badly warped tray
- Pain that does not settle after a few days
- Gum swelling, bleeding or mouth sores
Do not try to fix or reshape a damaged aligner at home. Your dentist will check it and advise on the next step, based on your individual treatment plan.
Frequently Asked Questions
1. Can I use toothpaste to clean my clear aligners?
It is better to avoid regular toothpaste on aligners. Many toothpastes are mildly abrasive and can leave fine scratches, making the trays look dull and collect stains. A soft toothbrush with cool water and a little mild, clear soap is usually enough.
2. Why do my aligners smell bad?
A bad smell usually means bacteria and plaque have built up on the trays or on your teeth. Rinse aligners each time you remove them, brush them gently every day, and brush your teeth before wearing them again. If the smell continues, ask your dentist to check your aligners and gums.
3. Can I clean my aligners with hot water?
No. Hot or boiling water can soften the plastic and change the shape of the trays. Even a small change can affect how well they fit. Use cool or lukewarm water instead. If an aligner looks warped, contact your dentist rather than wearing it.
4. Can I drink tea or coffee while wearing aligners?
Remove your aligners before drinking tea, coffee or any drink other than plain water. These drinks can stain the trays, and sugar trapped under them may increase the risk of cavities. Hot drinks may also affect the plastic. Rinse your mouth or brush before putting the aligners back in.
5. What should I do if I lose an aligner?
Contact your dentist as soon as possible. Depending on your stage of treatment, they may advise wearing the previous or next set until a replacement is arranged. Do not skip wearing aligners for long periods, as teeth can shift. Keeping your aligners in their case whenever they are out helps prevent loss.
