How to clean Invisalign Aligners?


The vast majority of patients who choose Invisalign over other equally effective orthodontic treatments do so because of the characteristics that the aligners provide: they are transparent, very comfortable and practically imperceptible.

It is precisely for this reason that you must be very careful when keeping aligners in good condition.

In this way, we will prevent them from staining and deteriorating. If they do, they will lose the transparency that makes Invisalign such an attractive treatment.

That said, it is also true that the fact that the aligners are renewed so frequently – every two weeks – facilitates their maintenance.

Therefore, keeping the aligners in good condition is due to the very need to preserve the unique qualities of the aligners since, the more they are cared for, the more discreet they will be in the eyes of others.

But, in addition, its cleanliness helps us preserve our own oral hygiene. That is, if the aligners are not cleaned properly, it will favor the accumulation of food remains in the mouth and the appearance of bad breath.

Do not clean the aligners with toothpaste or soak them in mouthwash, as these products damage the aligner, making it opaquer and more visible

Is Invisalign a hygienic treatment?

That said, it is also important to note that in addition to its aesthetic characteristics, Invisalign is a method that stands out for being more hygienic than any other orthodontic treatment.

This is because it is the only removable system. In this way, it allows both cleaning the aligners individually and brushing the teeth normally.

And, contrary to what happens with the rest of the treatments, it is removed to eat and brush its teeth. Therefore, since it is not placed on the patient’s teeth while carrying out these activities, it does not disturb or interfere with daily hygiene.

How should I clean the Invisalign aligners?


That said, we are going to detail how the aligners should be cleaned so that they do not lose the transparency and discretion that characterizes them.

First of all, we will have to brush them several times a day, that is, every time we remove them and put them in their box.

This will be done when we remove the aligners to eat, for example, and will consist of cleaning the surface of the splint with a brush, warm water and soap.

Secondly, it will also be advisable to dilute a special tablet to clean dental prostheses in a glass of water once or twice a week.

These types of pills are marketed by different brands and are for sale in pharmacies. Its use helps to maintain the cleanliness of the aligners since they do not acquire bad odours.

At this point it is important to mention that toothpaste should not be used as a substitute for soap or mouthwash to immerse Invisalign.

Although they are suitable for our own hygiene, this type of product damages the material with which the splint is made.

That is, they deteriorate its surface, making it opaque and more visible to the eyes of others. In addition to this, granulated toothpaste grates the aligners.

What else can I do to take care of the aligners?

In addition to being careful with our own hygiene and with that of the aligners, it is also important to carry out what we would call a preventive cleaning of them.

That is, there are a series of habits that deteriorate their appearance despite cleaning them. The main ones would be: smoking and drinking liquids with coloring while we have them on.

Any patient wearing Invisalign knows not to eat while wearing the aligners. However, the same does not happen when it comes to smoking or drinking coffee, tea or soft drinks such as Coca-Cola.

The most appropriate thing is that the aligners are removed when carrying out any of these habits. However, in the case that they are performed very frequently, it will be necessary to assess this point, since the aligners must be worn 22 hours a day.

In any case, if you have questions about the cleaning or maintenance of the Invisalign aligners and you don’t even know what products to buy, our orthodontists – will be able to answer all your questions.
