Can Invisalign Protect Your Teeth Against Cavities? What to Know

One of the most common oral health issues is cavities. They can be frustrating to deal with as a patient, so you might’ve heard plenty of ways to prevent them. But those who started Invisalign often wonder if they can still get this dental problem. The trays act like shiels, almost, so are they a concern? Keep reading to learn why you should still be aware of decay and how to avoid it.

Should I Be Worried About Cavities During Invisalign?

Your clear aligners are made from a thin plastic that fully covers your teeth. While they may offer some minor protection against things like bruxism, cavities can be sneaky and cause trouble. These dental problems occur when bacteria dissolve your enamel with an acid they produce when they eat sugar and starch. If you don’t properly clean out your trays and smile after mealtime, then you may be at a higher risk.

Would I Need to Visit My Dentist About Cavities During Invisalign?

The short answer to this question is yes! Cavities can cause issues the bigger they get with Invisalign. For instance, minor ones are often fixed with fillings, which often don’t interfere with your treatment. However, if you need a crown or something else, then they may make the aligner feel off. That’s because the fit of your trays is precise, so any changes can lead to some problems.

How Can I Prevent Cavities?

Although you are still at risk of developing a cavity, there are things you can do to prevent it. Here are some easy tips you can follow:

  • Clean your aligners at least once a day. Before or after every meal is even better, but use clear, gentle soap with a soft-bristle toothbrush to remove any plaque that’s stuck to them.
  • Brush your teeth with fluoride toothpaste to help strengthen your enamel.
  • Don’t forget to floss to get rid of bacteria between your teeth.
  • Only drink water when you have your trays in and don’t eat anything.
  • Have sugar in moderation.

One of the best things you can do is to stick to your checkup visits with your dentist. Not only will they monitor how your treatment is going, but they can catch any oral health issues while they are minor. That way, they get fixed before they cause a bigger headache and keep you on track.
