Understand Clear Aligner and their material usability

These materials are custom-made to fit the patient’s teeth and are virtually invisible, providing a more comfortable yet aesthetically pleasing option for teeth straightening.

A daily cleaning routine for clear aligner trays is important for maintaining good oral hygiene, preventing bad breath, and ensuring the trays’ longevity. Here are some key points highlighting the importance of daily cleaning:

  • Removes saliva buildup: Rinsing your tray aligners every time you remove them for eating or drinking helps remove saliva buildup, which can cause bad breath and affect the trays’ fit.
  • Prevents stains and discoloration: Clear aligners can be prone to stains and discoloration, especially from colored or heavily scented soaps. Using clear antibacterial soap and avoiding colored soaps helps keep the trays invisible and free of stains.
  • Maintains good oral hygiene: Proper cleaning methods, such as using recommended cleaning solutions or creating your own solutions like hydrogen peroxide, help maintain good oral hygiene and prevent bad breath.
  • Prolong tray life: Proper cleaning and maintenance of clear aligner trays ensure their longevity and effectiveness in teeth straightening.

Best Ways To Clean The Clear Aligners

Keeping your clear aligners sparkling clean doesn’t have to be a hassle. We’ve got seven best ways to clean aligners. Let’s explore these methods together!

  • Aligner Experts Cleaning Foam: We provide a special hygiene kit with aligners that contain an effective aligner cleaning foam. When you clean the aligners with the cleaning foam, it leaves the aligners sparkling clean without damaging them.
  • Denture Cleaners: Soaking your aligners in a denture cleaner, such as Efferdent or Polident, during meals can help keep them fresh and clean. After soaking for 15 minutes, use a toothbrush to brush off any residual buildup. While some dentists caution against this method, many patients find it effective despite potential cloudiness.
  • Retainer Brite: Similar to denture cleaners, Retainer Brite is designed to maintain the cleanliness of your aligners. It shares the same soaking method as denture cleaners but is formulated with the proper pH to protect the plastic material.
  • Antibacterial Liquid Soap: Brushing your aligners with antibacterial soap offers a simple way to eliminate bacteria accumulation. After brushing, rinse the trays thoroughly before placing them back in your mouth.
  • Mouthwash: Some patients prefer soaking their trays in mouthwash for cleaning purposes. However, it’s important to note that colored mouthwashes may leave a tint on your aligners. To avoid discoloration, consider using a clear whitening mouthwash.
  • Vinegar: Make a solution with half vinegar and half warm water, soak your aligners while enjoying a meal, and then brush and rinse them off afterward. Remember to let them dry thoroughly before reinserting them.
  • Hydrogen Peroxide: Hydrogen peroxide is known for its bacteria-fighting properties, making it a useful cleaning agent. Create a solution using half hydrogen peroxide and half water, and let your trays soak for approximately 20 minutes. This method is comparable to using denture cleaners but is significantly more affordable.
