Clear aligners are an easy and comfortable way to straighten your teeth — but to get the best results, you have to use them correctly. Many people make small mistakes without realizing it, and those mistakes can slow down their treatment.

Here are the top 3 common mistakes people make with aligners and the right way to fix them.

Mistake 1: Not Wearing Aligners for 22 Hours a Day

Your aligners only work when they’re in your mouth. They gently move your teeth by applying steady pressure.
If you take them out too often — for meals, snacks, or long breaks — your teeth won’t move as planned, and your treatment can take longer.

Why it’s a problem:
Each set of aligners is made to move your teeth just a little every week or two. If you wear them less than 22 hours a day, your teeth don’t get enough pressure, and you may have to wear the same set longer.

The right way:

• Wear your aligners 22 hours every day.

• Only remove them for eating, drinking (anything other than water), and brushing.

• Set phone reminders or use an aligner-tracking app.

• If you skip hours, don’t rush to the next set — talk to your dentist before switching.

Mistake 2: Forgetting to Wear Retainers After Treatment

Once your aligner treatment is done, you’re not completely finished. After your teeth move into place, they need time to settle. That’s where retainers come in. Some people stop wearing them too soon — and that can undo all their hard work.

Why it’s a problem:
Without retainers, your teeth can slowly move back to where they were. This is called “relapse,” and it can happen faster than you think.

The right way:

• Wear your retainers as told by your dentist — usually full-time for a few months, then only at night.

• Always keep them clean and store them in their case when not in use.

• If your retainers feel tight after skipping a few nights, wear them full-time again until they feel normal.

• Replace broken or lost retainers quickly so your teeth don’t shift back.

Mistake 3: Not Using Chewies

Chewies are small, soft cylinders that help your aligners fit perfectly. Some people think they’re not important — but they actually make a big difference in how well your aligners work.

Why it’s a problem:
If your aligners don’t fit tightly, small air gaps can form between your teeth and the aligner. This means your teeth won’t move as planned and your next set might not fit properly.

The right way:

• Use your chewies for 5–10 minutes every day, especially when you switch to a new set.

• Bite down gently and roll the chewie along your teeth to make sure your aligners sit firmly.

• Replace chewies once they lose their bounce.
