This can affect your confidence and self-esteem, as well as the effectiveness of your treatment.
Reduced aligner lifespanYour aligners are made of durable plastic, but they can wear out faster if you don’t take good care of them.

Let’s Bust Some Common Myths

It is essential to be well aware of what this treatment has to offer.
It is essential to be well aware of what this treatment has to offer.

There are many misconceptions and myths about clear aligner care that may lead you to make mistakes that may harm your aligners or your oral health. 

Here are some of the most common ones and why they are false:

Myth 1: Using toothpaste is fine for cleaning aligners


Toothpaste is not suitable for cleaning clear aligners, as it may contain abrasive ingredients that may scratch or dull the surface of the aligners, making them more visible and prone to staining.

Instead, use a soft-bristled brush and a mild cleaning solution to gently clean your aligners.

Myth 2: Hot water cleans aligners better


Hot water is not good for clear aligners, as it may cause them to warp or shrink, affecting their fit and function. 

Always use lukewarm or cold water to rinse or soak your aligners.

Myth 3: Soaking aligners in mouthwash keeps them fresh


Mouthwash is not a good option for soaking clear aligners, as it may contain alcohol or coloring agents that may dry out or stain the aligners. Also, mouthwash does not remove the bacteria or plaque that may accumulate on the aligners. 

Instead, use a denture cleaner or a baking soda solution to soak your aligners for about 15 minutes once a day.

Myth 4: You only need to clean your aligners once a day


You need to clean your clear aligners every time you take them off or put them on, which should be at least twice a day. This will help prevent bacteria buildup, odor, and staining on the aligners. 

Also, remember to brush and floss your teeth before wearing your aligners, as any food particles or plaque left on your teeth may transfer to the aligners.

Myth 5: You can skip aligner cleaning for a day or two if you’re busy


Skipping clear aligner cleaning is not advisable, as it may lead to serious oral health problems such as cavities, gum disease, bad breath, or infections. Also, it may affect the effectiveness of your aligner treatment, as dirty aligners may not fit or move your teeth properly. 

Therefore, make aligner cleaning a part of your daily routine, and do not compromise on it.

Myth 6: Aligners don’t need deep cleaning


Aligners do need deep cleaning once in a while, as regular cleaning may not remove all the bacteria or plaque that may be stuck on the aligners. You can use an ultrasonic cleaner or a professional cleaning service to deep clean your aligners. 

However, consult your dentist before using any such methods, as some may not be compatible with your aligners.

Myth 7: You can use any cleaning solution for your aligners


Not all cleaning solutions are safe or effective for clear aligners, as some may contain harsh chemicals that may damage or discolor the aligners. Also, some may not kill all the germs or remove all the plaque that may be on the aligners. 

Therefore, use only recommended cleaning solutions for your aligners, such as denture cleaners, baking soda solutions, or aligner-specific products.

Myth 8: Your aligners will automatically stay clean if you brush well


Brushing well is important for your oral health, but it is not enough to keep your clear aligners clean. You still need to clean your aligners separately, as brushing alone may not reach all the areas or corners of the aligners where bacteria or plaque may hide. 

Also, brushing may not remove the stains or odors that may develop on the aligners over time.

Myth 9: You can clean your aligners with soap and water only


Soap and water are not sufficient for cleaning clear aligners, as soap may leave a residue on the aligners that may affect their clarity or comfort. Also, water alone may not remove all the bacteria or plaque that may be on the aligners. 

Therefore, use a mild cleaning solution along with soap and water to thoroughly clean your aligners.

Myth 10: Clear Aligners don’t need to be replaced as often as traditional braces


Clear Aligners do need to be replaced periodically, as they may wear out or lose their shape over time. This may affect their ability to move their teeth effectively and comfortably. Your dentist will provide you with a set of aligners that you will need to change every one or two weeks, depending on your treatment plan. 

Do not skip or delay changing your aligners, as this may slow down or compromise your treatment results.

Keeping your clear aligners clean is not only important for their appearance but also for their effectiveness and health. 

By following these simple steps, you can ensure that your aligners stay clear, fresh, and comfortable throughout your treatment. 

You can also enjoy the benefits of having a beautiful and healthy smile that you can be proud of.
