A common oral health issue that many people face is cavities. They are a problem you might’ve heard about since you were younger, as they can be uncomfortable to deal with. That said, you might wonder if you need to worry about them during your Invisalign treatment. After all, they are trays that cover your teeth! Here’s how they are still a possibility and what you can do to avoid decay.

Why Should I Worry About Cavities with Invisalign?

While clear aligners can be helpful even with things like bruxism, it’s still possible to get a cavity during your treatment. That’s because you will need to remove them when you eat. Your teeth will be exposed to the sugars and starches you consume, which feed the bacteria in your mouth. They will then produce enamel-dissolving acid that causes trouble. So, you should make sure you are brushing and flossing.

Do I Have to Visit My Dentist About Cavities with Invisalign?

Just like if you weren’t doing Invisalign, it’s important that you visit your dentist right away. Oral health issues like these can’t heal on their own, so getting them caught sooner will help you avoid serious complications, like tooth loss in extreme cases.

Better yet, you increase your chances of only needing a filling, which typically doesn’t affect orthodontic treatments either. Other options, like crowns, may pose a unique challenge, but your dentist is here to help you through it.

So, How Can I Prevent Cavities?

With all that said, the best thing you can do is to prevent cavities in the first place! These are some easy tips you can follow:

  • Brush your teeth after you eat with fluoride toothpaste to strengthen your enamel.
  • Floss every day to remove bacteria between your teeth.
  • Clean your aligners at least once daily, but before or after your meals is even better. You can use a soft-bristle toothbrush and clear, gentle soap.
  • Only drink water when wearing your trays and keep sugary foods in moderation.

Don’t forget to keep up with checkups with your dentist. They will be able to make sure your treatment is going on track and that there aren’t any oral health issues getting in the way. That way, you have a smooth treatment toward your straighter smile.
