We all love the ease and convenience that clear aligners offer, however, one common complaint among wearers is the unpleasant odor that can develop over time. This odor can be caused by bacteria buildup or the accumulation of food particles in the aligners. Fortunately, there are several simple and effective home remedies that can help you reduce clear aligner odor, ensuring a fresh and confident smile. Here are a few remedies to get rid of the odor and practical tips to combat aligner odor.

Proper Oral Hygiene

The foundation of any effective remedy for clear aligner odor lies in maintaining proper oral hygiene. It is crucial to brush your teeth after every meal and before inserting your aligners. Use a soft-bristled toothbrush and fluoride toothpaste to thoroughly clean your teeth, gums, and tongue. Pay special attention to any hard-to-reach areas, as bacteria can easily accumulate there. By keeping your mouth clean, you reduce the chances of bacterial growth and prevent the transfer of odors to your aligners.

Soaking in Denture Cleansers

Denture cleansers can be highly effective in combating clear aligner odor. These cleansers are readily available in most drugstores and are designed to remove stains, bacteria, and odors from dental appliances. To use this remedy, dissolve a denture cleanser tablet in a glass of warm water and let your aligners soak for the recommended time. Rinse them thoroughly before reinserting. Denture cleansers not only eliminate odor-causing bacteria but also help to remove any plaque or tartar buildup that may accumulate on your aligners.

Baking Soda Solution

Baking soda, also known as sodium bicarbonate, is a versatile household ingredient renowned for its deodorizing properties. Creating a baking soda solution to soak your clear aligners can help neutralize odors effectively. To prepare the solution, mix one teaspoon of baking soda with half a cup of warm water. Place your aligners in the solution and let them soak for about 15-20 minutes. Afterward, give them a thorough rinse with water before reinserting. Baking soda not only eliminates odors but also helps to maintain the clarity of your aligners by removing stains.

Vinegar Solution

Vinegar, particularly apple cider vinegar, is another fantastic natural remedy for reducing clear aligner odor. Its acidic nature helps to kill bacteria, disinfect the aligners, and neutralize unpleasant smells. To use vinegar as a remedy, create a solution by mixing equal parts of vinegar and water. Soak your aligners in the solution for 15-20 minutes, ensuring they are completely submerged. Afterward, rinse them thoroughly with water before wearing them again. However, be cautious not to use vinegar too frequently, as its acidic nature may damage your aligners over time. Limit vinegar treatments to once or twice a week.

Oral Rinse

An effective way to combat clear aligner odor is by incorporating an antibacterial oral rinse into your daily routine. Look for a non-alcoholic, antimicrobial mouthwash that is safe for orthodontic appliances. Rinse your mouth with the oral rinse after brushing your teeth and before inserting your aligners. This will help to eliminate odor-causing bacteria and leave your aligners smelling fresh. It is essential to choose an oral rinse that is specifically designed for orthodontic patients, as it will be gentle on your aligners and not compromise their transparency.


With these strategies in place, you'll not only achieve a beautifully aligned smile but also enjoy the confidence that comes with knowing your aligners are odor-free and ready to help you achieve your desired dental transformation. However, it's important to remember that while these remedies can be effective, consistency and diligence are vital.
