Orthodontic aligners are becoming more popular than traditional braces. They are comfortable, removable, and less noticeable. But while they look simple, they come with one major responsibility—keeping both your teeth and the aligners clean. A recent scientific review looked at how people clean their aligners at home and what methods work best. This blog summarizes the key findings so both patients and doctors can make informed decisions.
Aligners are made from thermoplastic material that covers the entire tooth surface. Because of this, plaque and bacterial biofilm can easily build up. If not cleaned properly, this biofilm can cause gum problems, bad breath, and even increase the risk of cavities or gum disease. The studies found that mechanical and chemical cleaning methods work best when used together. Just rinsing aligners with water was the least effective method.
The most effective aligner cleaning methods included:
Aligners cleaned with a combination of brushing and soaking showed the lowest levels of bacteria.
Patients with clear aligners generally had better oral health than those with fixed braces. This is because aligners can be removed while brushing and flossing.
Key findings include:
However, just using a toothbrush may not be enough. The most effective protocols used additional tools like floss, interdental brushes, and in some cases, water flossers or sonic toothbrushes.
For dental professionals, this review reinforces the importance of customizing oral hygiene instructions for aligner patients. Here are key takeaways:
Also, because some studies showed low-quality evidence due to design limitations, further research is still needed.
If you’re wearing clear aligners, keeping your mouth and trays clean is your daily job. Here’s how to do it well:
1. Donʼt rely on water alone. Rinse, but also brush your aligners daily with a soft toothbrush.
2. Use cleaning tablets (eg. Clinsodent tablets) at least once a day. They help reduce bacteria that brushing alone canʼt remove.
3. Brush and floss your teeth every time before putting your aligners back in.
4. Consider a water flosser or electric toothbrush if you find it hard to clean well.
5. Replace aligners on schedule, and donʼt wear dirty ones longer than recommended.
Your aligners are close to your teeth all day, so any bacteria that grow there can directly affect your gums and enamel.
Aligners offer comfort and aesthetics, but they demand good hygiene. This review shows that the best results come from combining mechanical and chemical cleaning methods. Whether youʼre a doctor advising patients or
someone undergoing aligner treatment, knowing how to care for the trays and your teeth is crucial.
Clear aligners donʼt clean themselves—your daily routine does the job.
