Bad breath is never desirable, so we’re going to go over some of the key causes of bad breath from your aligners and the invisible braces accessories you’ll need to keep your breath fresh. As long as you avoid these habits and make sure to clean your aligners regularly, you can keep your breath smelling fresh throughout your treatment.

1. Forgetting to Take Out Your Aligners When Eating or Drinking

Your aligners are designed to stay in as much as possible — except for mealtimes

Though Invisalign does not have any dietary restrictions like the ones you need to follow while wearing metal braces, there are still some rules to follow around mealtimes. The first thing you should know about Invisalign hygiene is that you need to take out your aligners every time you eat or drink. What can you drink with Invisalign? The only instance where you don’t need to remove your aligners is when you are drinking plain water. Any other drink, especially any drinks containing sugar will lead to Invisalign bad breath. 

Should you eat or drink anything other than water while you have your Invisalign in, the food or drink can get stuck to your aligners. Once the food or drink is stuck to your aligners, bacteria will begin to grow. Since your saliva can’t reach the bacteria, you are at a greater risk for bad breath.

2. Not Brushing Your Teeth and Cleaning Your Aligners After Every Meal

Now that we know to remove our aligners before mealtime to prevent invisalign bad breath, it’s time to talk about aligner care after mealtime. After you are finished eating or drinking, you should at minimum brush your teeth and rinse your aligners. If you have the time, you should also carefully brush your aligners with a soft bristle toothbrush to make sure that there isn’t any remaining plaque or food particles. Should you consistently forget to brush your teeth and aligners, your Invisalign will begin to cause bad breath due to bacteria growth.

3.Not Cleaning Your Aligners Often Enough

Remember that you should deep clean your aligners every few weeks

Brushing your teeth and aligners after eating will help you prevent Invisalign bad breath in the short term. However, over time plaque and bacteria can still stick to your aligners and cause bad breath. To prevent this, you should deep clean your aligners once a week so they can stay fresh for longer. There are a lot of home remedies that you can use to quickly and easily deep clean your aligners. Just remember to set aside about a half hour each week to really get your aligners clean.
