If you want to keep your smile on track with Invisalign, you’ll need to follow some simple do’s and don’ts. These tips can affect how well your aligners work, how comfortable the process is, and how long your treatment takes. Working toward a straighter smile doesn’t have to be hard; just keep these suggestions in mind for a more enjoyable and successful experience.

What Should You Avoid While Wearing Invisalign?

Invisalign aligners offer the freedom that traditional braces don’t, but that doesn’t mean you can do whatever you want while undergoing treatment. There are certain things you’ll need to avoid if you want to prevent a delay, such as:

  • Don’t Eat (or Drink) While Wearing Your Aligners: Your bite pressure can damage your trays and require replacements. Hot liquids can warp the material, causing it to fit poorly. Remove them before eating a meal or taking a sip.
  • Don’t Use Abrasive Toothpaste: Many toothpaste brands use abrasive ingredients that can scratch your aligners. This makes them more visible. Instead, use clear soap and a soft-bristled toothbrush to keep them clean (and discreet)!
  • Don’t Forget to Wear Them 20-22 Hours a Day: Failing to wear your trays for 20-22 hours a day can cause a delay. Your teeth won’t move as they should, which can put you behind in your treatment plan. Set a timer or use an app to help you stay on track.

What Should You Do While Wearing Invisalign?

Now that you know what to avoid, it’s time to learn what to do while wearing Invisalign:

  • Do Keep Your Aligners Protected: When you’re not wearing your aligners, keep them in a protective case. Placing them in a napkin or laying them on the counter increases the chance of damage or loss. A case helps you know where they are and keeps them fully protected.
  • Do Clean Your Teeth Before Reinserting Your Aligners: Aligners are meant to fit snugly against your teeth, so if you want to lower the risk of bacteria and food particles getting trapped, brush and floss your teeth. This will keep your smile and trays healthier over time.
  • Do Use Invisalign Cleaning Crystals: Soak your aligners several times a week to achieve a deeper clean. Using Invisalign Cleaning Crystals helps remove additional bacteria that can cause foul odors.
  • Do Rinse Your Aligners When Removing Them: Rinsing your aligners with cool water helps remove saliva and plaque, so taking a few seconds to wash them off will better protect your trays and your smile.

These simple do’s and don’ts will make your treatment a seamless experience, but if you have additional questions or need help with your Invisalign, don’t hesitate to contact your dentist.
