Clear Aligners, Clear Rules: The Ultimate Invisalign Cheat Sheet

June 6, 2025

Patient smiling with their Invisalign aligners

Invisalign makes it easier than ever to straighten your smile—no brackets, no wires, no metal mouth. But just because it’s simple doesn’t mean there aren’t any rules. These clear aligners come with their own set of guidelines, and following them can make or break your results. If you’re keen to avoid some common mistakes, continue reading. You’ll find a quick guide to the dos and don’ts of Invisalign treatment.

DO Wear Your Aligners for the Recommended Time

While it sounds obvious, it’s important to note that Invisalign only works when it’s on your teeth. This means you’ll need to wear your trays for at least 20 to 22 hours every day. To meet that wear time requirement, you should only take them out to eat, drink anything other than water, or brush your teeth. The more consistent you are, the faster and more predictable your results will be!

DON’T Eat with Your Invisalign in Your Mouth

Even though the trays are durable, they’re not built for chewing. Eating with Invisalign can crack or warp your aligners, especially if you do it consistently. On top of this, any food or drink that’s not water can get trapped underneath, leading to worn enamel or stained trays.

When it’s mealtime, be sure to pop your aligners out and store them before enjoying your food.

DO Clean Your Trays Every Day

Your aligners sit against your teeth all day, which means they can collect bacteria, plaque, and odors easily. So, rinse them with lukewarm water and gently brush them with a soft toothbrush at least once a day. You can also use Invisalign cleaning crystals for a deeper clean a few times a week.

DON’T Expose Your Invisalign Aligners to Heat

Invisalign is made using a flexible, but durable plastic called SmartTrack. While it does well with some types of stress, it can’t handle heat. So, never rinse your trays with hot water, and don’t leave them on the dashboard of your car, or by the stove.

DO Keep Your Previous Trays Handy

If you lose or damage your current aligners, having the previous set can be a lifesaver. It helps keep your teeth in place while your dentist orders a replacement. Think of them as a backup plan in case something goes wrong. This one simple tip can save you hours of frustration later on.

Clear aligners give you freedom, but that freedom comes with responsibility. Stick to these guidelines, and you’ll be flashing a straighter smile before you know it. If you ever have questions, don’t hesitate to reach out to your dental team. They’ll help keep your treatment on track!
