Invisalign has become a popular choice for straightening teeth because it’s comfortable, discreet, and convenient. However, some people assume that because the aligners cover their teeth, they’re protected from cavities. Unfortunately, that’s not entirely true. It is possible to get cavities during Invisalign treatment, but the good news is, with the right care, you can easily prevent them.
How Cavities Develop During Invisalign Treatment
Cavities form when bacteria in your mouth feed on leftover food particles and sugars, producing acids that erode your tooth enamel. When you wear Invisalign aligners, those bacteria can become trapped against your teeth, especially if you haven’t brushed or flossed before putting your trays back in.
Unlike braces, which make cleaning more challenging because of brackets and wires, Invisalign’s main risk factor comes from wearing aligners for long periods without proper cleaning habits. Since you’re advised to wear your aligners for 20 to 22 hours a day, there’s little opportunity for your teeth to “breathe” if you don’t remove them for thorough hygiene.
Common Causes of Cavities During Invisalign Treatment
Poor Brushing and Flossing Habits
If you skip brushing after meals or snacks, food particles and bacteria remain on your teeth—and when you reinsert your aligners, you essentially trap those cavity-causing acids.
Wearing Aligners After Sugary Drinks or Snacks
Drinking soda, juice, or even flavored water while wearing your aligners can allow sugar and acid to sit directly against your enamel. This is one of the quickest ways to develop decay during Invisalign treatment.
Not Cleaning Aligners Properly
Dirty or cloudy aligners can harbor bacteria. If you don’t clean them daily with the proper solution or rinse them thoroughly, that bacteria transfers back to your mouth each time you wear them.
How to Prevent Cavities While Wearing Invisalign
Brush and Floss After Every Meal
Before you put your aligners back in, always brush and floss. This removes debris and prevents bacteria from being sealed in. Carry a travel toothbrush and toothpaste so you can clean your teeth even when you’re away from home.
Clean Your Aligners Daily
Rinse your aligners every time you remove them, and use a gentle, non-abrasive cleanser at least once a day. Avoid using toothpaste on your trays—it can scratch the surface and create places for bacteria to hide.
Avoid Sugary Foods and Drinks
Stick to water when your aligners are in, and limit sugary or acidic drinks overall. This simple habit can drastically reduce your risk of cavities.
Visit Your Dentist Regularly
Even during orthodontic treatment, your dentist should check your teeth for early signs of decay. Regular cleanings and fluoride treatments can keep your enamel strong.
Invisalign is an amazing tool for achieving a beautiful, straight smile, but maintaining your oral hygiene is just as important during treatment as it is before or after. By brushing, flossing, and cleaning your aligners consistently, you can prevent cavities and ensure your new smile is not only straight, but healthy and strong for years to come.
