When you start Invisalign, it’s easy to assume your teeth are fully protected under the clear aligners. After all, they act like a smooth, comfortable shield over your enamel. However, cavities can still develop during treatment. In some cases, the risk can even increase if you’re not careful about your oral hygiene and eating habits.
Understanding how cavities form and what to do when you spot a problem can help you stay on track toward a healthy, beautiful smile.
Can You Get Cavities with Invisalign?
Yes, it is possible to get cavities during Invisalign treatment. Your aligners fit snugly against your teeth, creating a sealed environment. If food particles or plaque are trapped when the trays go in, bacteria have the perfect space to thrive. They feed on sugars and produce acids that weaken enamel, eventually creating a cavity.
Unlike traditional braces, Invisalign makes brushing and flossing easier since you can remove the trays. However, the aligners can also contribute to cavity development if you wear them without cleaning your teeth first or sip sugary or acidic drinks while they’re in. Anything left behind becomes locked against your enamel for hours at a time, accelerating decay.
What to Do If You Notice a Cavity
If you suspect you have a cavity, don’t wait until your next scheduled appointment. Tooth decay doesn’t resolve on its own, and delaying treatment can make the problem worse. Call your dentist right away so they can evaluate the affected tooth and recommend treatment.
Most small cavities can be treated with a simple filling without interrupting your Invisalign progress. Your dentist will restore the tooth, make sure the filling fits comfortably with your aligners, and help you continue your treatment as planned. However, larger cavities or infections may require more involved procedures, which could temporarily slow your aligner schedule.
It’s also important to follow your dentist’s guidance after treatment. They may adjust your wear time or provide additional cleaning recommendations to protect the repaired area.
Tips to Prevent Cavities During Treatment
Preventing cavities during Invisalign comes down to consistent oral care and mindful habits. The most important step is brushing and flossing before putting your aligners back in. This removes food and plaque so they aren’t trapped against your teeth.
You should also avoid drinking anything other than water while wearing your trays. Sugary drinks, coffee, sports beverages, and even flavored sparkling water can introduce acids and sugars that linger under the aligners. If you do enjoy something other than water, remove your trays first and brush before putting them back in.
Cleaning your aligners daily is another key step. Bacteria can collect on the trays themselves, transferring back onto your teeth. Rinse them after meals and follow your dentist’s instructions for proper cleaning. Staying well hydrated can help, too, since saliva naturally washes away food debris and neutralizes harmful acids.
With good hygiene and a little extra attention, you can keep your smile healthy while straightening your teeth.
A little care goes a long way in protecting your oral health during Invisalign.
