Caring for Your Invisible Aligners: Best Practices for Longevity

Invisible aligners are a convenient and discreet way to straighten your teeth, but they only work as well as you care for them. Neglecting proper maintenance can lead to staining, bad breath, discomfort, and even delays in treatment. Whether you're just starting your clear aligner journey or well into your transformation, building the right habits ensures your aligners stay clear, effective, and comfortable from start to finish.

Let’s explore the essential practices to keep your Smileie aligners in great shape, and your smile on track.

Why Aligner Care Matters More Than You Think

Unlike metal braces, clear aligners sit directly against your teeth and are removed daily. This means they’re more exposed to bacteria, saliva, and wear and tear. If not cleaned or handled properly, aligners can become discolored, smelly, or even lose their shape, compromising your treatment progress and oral health.

Keeping them clean not only preserves their invisibility but also protects your gums and teeth from plaque buildup, cavities, or irritation. It’s not just about aesthetics, it’s about hygiene and results.

Start With a Consistent Cleaning Routine

Cleaning your aligners twice a day is the foundation of good care. Each morning and night, rinse them under lukewarm water (never hot) and gently brush them using a soft toothbrush and a mild, clear soap. Avoid toothpaste, it can scratch the plastic and cause cloudiness over time.

In addition to daily cleaning, soaking your aligners once in a while in a clear aligner-safe solution helps remove any lingering buildup. This keeps them fresh and odor-free, especially if you wear them for 20–22 hours a day, as recommended.

Don’t Eat or Drink With Your Aligners On

While it might be tempting to sip coffee or snack without removing your aligners, doing so can cause permanent staining or even warp the material. Food particles and sugars get trapped between your teeth and the aligners, creating a perfect environment for bacteria to thrive.

Only plain, cold water is safe to drink while wearing aligners. Everything else, especially hot drinks or anything colored, should be avoided until after removal. And always rinse or brush before popping them back in.

Practice Good Oral Hygiene Before Reinserting Aligners

Every time you eat or drink something (other than water), it’s important to brush and floss before putting your aligners back in. Why? Because any food debris left behind gets pressed against your teeth by the aligner trays, increasing your risk of decay, gum issues, and bad breath.

When you’re on the go, keeping a travel-size toothbrush and floss in your bag makes it easier to stick to this habit. It takes just a minute but helps ensure your aligners, and your mouth, stay clean and healthy.

Store Aligners in Their Case, Always

One of the easiest ways to lose or damage your aligners is by leaving them out. Whether it’s during a meal or while brushing your teeth, your aligners should go straight into their designated case anytime they’re not in your mouth.

It may seem harmless to wrap them in a napkin or place them on the table, but many aligners end up accidentally tossed or stepped on. Your case isn’t just for protection; it also keeps them free from bacteria and dust.

If you do misplace or damage a set, contact the Smileie team immediately so we can guide you on next steps without interrupting your progress.

Follow Your Treatment Schedule Closely

Your treatment is carefully mapped out, and each set of aligners is designed to be worn for a specific amount of time. Delaying a switch or wearing them inconsistently can cause your teeth to shift out of sync with the plan, which may extend your overall treatment.

It’s a good idea to set calendar reminders for aligner changes. Most patients change aligners every one to two weeks, but you should follow the personalized plan provided to you. Keep your previous set handy as a backup in case of emergencies.

Keep an Eye on Your Progress

Monitoring your smile transformation can be incredibly motivating, but it’s also important for identifying potential issues. If an aligner feels too tight or too loose, or isn’t fitting as expected, it might mean your teeth aren’t moving correctly.

Smileie provides virtual check-ins throughout your treatment to keep everything on track. Always report any discomfort, shifting, or fit concerns to our dental team, we’re here to support you every step of the way.
