How to Prevent Cavities with Invisalign

Invisalign braces and aligners are a great alternative to traditional wire braces for any patient requiring corrective orthodontic care. One of the most appealing aspects of these invisible dental trays or aligners is the fact that the patient can properly clean their teeth. Unlike traditional wire braces that cannot be removed and can only be cleaned around, Invisalign braces offer the wearer the ability to remove the trays while the patient eats or drinks anything other than water and reinsert them afterwards. This aspect makes the invisible corrective braces a very attractive option but orthodontic patients must remember that cavities are still a possibility if proper dental care is not adhered to every day. Patients must have self-discipline and remember the instructions of their orthodontist to avoid cavities while wearing their invisible braces.


Invisalign braces and aligners must be worn for the majority of a day, typically 22 hours, so patients must take advantage of the time they are given to remove the aligners and properly clean the teeth and dental trays. The invisible trays should not be worn unless the patient has thoroughly brushed and flossed before reinserting them. Braces of all kinds can create the type of areas that harbor plaque and bacteria that make teeth harder to clean and decay more likely.

Orthodontists recommend eliminating certain foods and snacks while wearing any corrective braces and this includes the Invisalign dental aligners. Patients should avoid eating sticky and hard candies, popcorn, and sweet drinks such as soda, juices and teas or coffee. Particles from food left in the mouth will allow bacteria to be stuck under the dental trays and can eventually lead to decay of the patient’s teeth.

After eating or drinking the patient cannot simply reinsert the invisible braces. They must be cleaned along with the patient’s teeth. Orthodontists will usually provide their patients with the proper cleaning supplies such as brushes or soap specifically indicated for cleaning the invisible braces. Many patients choose to soak the corrective braces in a bowl of cold water and soap while they eat for an added level of cleanliness.

Another useful tool that patients can obtain from their orthodontist is Sodium Fluoride, usually used in gel form applied with a standard soft toothbrush. An orthodontist can write their patient a prescription for Sodium Fluoride in the proper strength to aid in the fight against cavities while wearing Invisalign corrective braces.

Because Invisalign corrective braces hold saliva and bacteria against a patient’s teeth for the majority of a day, the patient must have immaculate dental hygiene. It only takes a patient forgetting to brush, floss, and clean their braces one time for all of the good hygiene they have performed to be erased.
