Clear aligners provide convenience for straightening your teeth and can be removed when needed. However, to achieve the best results with your aligners, it is important that you clean and care for them properly. Not only will this help your aligners to stay clear and fresh, but it will also support the effectiveness and efficiency of your orthodontic treatment. If left untreated, problems may include mouth irritation, discoloration, and even delay progress.
This blog will guide you through the best ways to clean and maintain your clear aligners, helping you keep your oral health and achieve a straighter smile.
Why Cleaning Clear Aligners Matters
Clear aligners, such as Invisalign or similar brands, require regular maintenance to remain in excellent condition. These aligners come into close contact with your teeth and mouth; it’s important to keep them clean. Here’s why:
- Prevent Staining: Aligners discolor easily, especially if not cleaned well. This may be in the form of coffee, tea, or any other pigmented food, taken without removing the aligners.
- Maintain Hygiene: Food particles and bacteria can get trapped in clear aligners, leading to odor and possible gum problems. Regular cleaning prevents this plaque buildup and keeps your mouth fresh.
- Comfort is ensured: A buildup of plaque or food debris inside your aligners makes them irritating or uncomfortable to wear. Keeping them clean and clear ensures a smoother fit and greater comfort throughout your treatment.
How to Clean and Maintain Your Clear Aligners
Caring for your clear aligners doesn’t have to be complicated. Here are some simple and practical steps to help you maintain your aligners between dentist visits:
1. Wash Them Often
The first step in cleaning your clear aligners is to rinse them after each removal. This helps prevent saliva from building up on them and causing odors. Always rinse them with lukewarm water, not hot, which could warp the plastic.
2. Brush Your Aligners
Just like brushing your teeth, it’s important to brush your aligners daily. Use a soft toothbrush-not the one you use for your teeth-along with a gentle, clear soap or mild dish detergent. Avoid toothpaste, as its abrasives may scratch the surface of your aligners.
3. Soak Them in Cleaning Solutions
Soaking them once daily in a special cleaning solution for aligners or Invisalign cleaning crystals can remove built-up bacteria and stains. It’s an easy way to keep your aligners fresh and hygienic.
4. Keep Them Safe When Not in Use
Always store your clear aligners in a protective case when not wearing them. This will protect the aligners from damage, loss, and bacterial contamination. Make sure to clean the case routinely.
5. Avoid eating and drinking with them on.
While aligners allow you to return to your normal eating and drinking, it is advised that you remove them when eating or drinking anything other than water. Many foods and beverages could stain or damage your aligners. If you must drink something like tea or coffee, make sure you clean your aligners afterwards.
Best Practices in Maintaining Your Clear Aligners
While cleaning is necessary, it’s also important to care for your aligners in other ways to make sure they’re effective:
- Wear Them as Recommended: It is recommended that aligners be worn for 20–22 hours per day, taking them out for meals, drinks other than water, and toothbrushing.
- Check for Damage: Inspect your aligners regularly for cracks or other damage. Should you notice anything, immediately consult your dentist for further action.
- Clean Your Orthodontic Aligners Regularly: As your treatment progresses, you will move on to new sets of aligners. Keeping these clean and well-maintained ensures each new set fits appropriately and is comfortable.
Taking care of your clear aligners is an essential step to ensure the success of your treatment. Cleaning and maintaining your clear aligners with these easy steps will help you prevent common problems, such as discoloration or bacterial buildup, and lead to a healthier mouth and better overall results. Remember, these aligners are part of a more extensive process to reshape your smile, and taking good care of them means making the most of this opportunity.
