Clean aligners using a method suitable for their material. Avoid hot water, aggressive brushing, abrasives and unsuitable chemicals. Cleaning trays alone is insufficient: maintain toothbrushing and interdental care before putting them back in.
Why Should Clear Aligners Be Cleaned?
Since clear aligners are worn inside the mouth for many hours, a layer of bacteria can build up on them over time. Without regular cleaning, aligners can become cloudy, turn yellow, and develop a bad odour.
Bacteria that build up between the aligner and the tooth can also increase the risk of decay and gum problems. Aligners that aren’t kept clean can develop hardened buildup over time, which can negatively affect the aligner’s structure.
How Should Clear Aligners Be Cleaned Daily?
Clear aligners need to be cleaned regularly every day. After waking up in the morning, the aligner should be removed, oral care carried out, and the aligner cleaned before being put back in.
Whenever the aligner is removed for eating, it’s recommended to rinse it before putting it back in. Rinsing it regularly with water throughout the day helps reduce buildup on the aligner.
The detailed cleaning done before going to bed at night is the most important part of the daily routine. At this stage, both the teeth and the aligner should be cleaned carefully.
What Methods Can Be Used to Clean Aligners?
Clear aligners can generally be cleaned with lukewarm water and a soft-bristled brush. Gentle cleaning helps remove buildup on the surface of the aligner.
Some people prefer to use special cleaning products or aligner cleaning tablets. These products can help keep the aligner’s surface more hygienic.
It’s important that any products used to clean the aligners are suitable for the aligner material. Using the wrong product can cause scratches or cloudiness on the aligner’s surface.
What Should Be Watched For When Cleaning Clear Aligners?
Very hot water shouldn’t be used when cleaning aligners. High heat can warp the aligner material and reduce the effectiveness of the treatment.
Brushing the aligners too hard can also cause scratches on the surface. Bacteria build up more easily on scratched surfaces.
Aligners should always be stored in their own case when not in use. Aligners left out in the open can pose a hygiene risk or get lost.
Why Does the Aligner Case Need to Be Cleaned?
It’s not just the aligners that need regular cleaning — the case does too. Damp, enclosed environments provide a suitable ground for bacterial growth. This is why it’s recommended to clean and dry the aligner case at regular intervals.
