Is It Possible to Get Cavities During Invisalign Treatment?

Invisalign is one of the most popular orthodontic treatments because it can straighten teeth without the use of metal brackets and wires. It uses custom-made aligners that surround the teeth and apply gentle pressure in order to move them. Still, that may raise some questions. For example, since the aligners place a barrier around teeth, is it still possible to get cavities during Invisalign treatment? This blog post provides important information.

How Cavities Form During Invisalign Treatment

Sadly, it is possible for cavities to form even while you are using Invisalign aligners.

Cavities are the result of oral bacteria interacting with sugars and starches in your mouth. They form a sticky, acidic biofilm on teeth that is known as plaque. Plaque can harden into tartar, which in turn can cause damage to the tooth enamel. Eventually, small holes — cavities — start to form.

Invisalign places a barrier around your teeth, but it cannot protect them from decay. Cavities can form during treatment in a couple of ways:

  • You should remove your aligners when you eat and drink. If you consume anything other than plain water while wearing your aligners, you could damage them. Therefore, your bare teeth will be exposed to starches and acids whenever you eat.
  • Food particles might get trapped in your aligners. If you do not keep your teeth and your aligners clean, food particles and bacteria could easily get trapped inside your Invisalign, giving them ample opportunity to cause damage.

Keeping Your Teeth Healthy During Invisalign Treatment

The key to preventing cavities during Invisalign treatment is thorough oral hygiene. You should:

  • Rinse your aligners before placing them in your mouth.
  • Thoroughly clean your aligners at least once a day.
  • Brush and floss your teeth after each meal.
  • Consume a balanced diet that is low in sugar.
  • Visiting your general dentist for regular checkups and cleanings.

What if, despite your best efforts, you notice that one of your teeth has a small hole or is extra-sensitive? Visit your dentist. If you are diagnosed with a cavity, they may place a filling. The filling will be shaped to match the natural curvature of your tooth, so it should not interfere with the way your Invisalign aligners fit. Your dentist may provide personalized coaching to help you avoid additional cavities during and after your orthodontic treatment.

Invisalign cannot make your teeth invulnerable to cavities! Continue to practice good habits so you can keep your smile healthy and strong throughout your treatment.
