I’m passionate about fixing teeth because I know a beautiful, functional smile is so much more than looking good. It affects a person’s entire life! I love helping people because it’s directly tied to my faith in Jesus Christ.
1. Rough Edges on Aligners
Invisalign aligners are made from a specialized, precision-cut, thermoformed plastic. While they’re designed to be comfortable, sometimes (rarely actually) the edges of the aligners can be rough, causing irritation to your child’s gums and the inside of their lips. If this happens, don’t worry! It’s an easy fix.
Here’s what you can do:
- Scissors or cuticle cutters (you can grab these for about $6). The cuticle cutters are preferred as they allow you to make precision small cuts.
- Emery board (a simple nail file will do, and it costs about $3). It’s also called a dual-sided salon board.

Carefully trim or file the rough edges to smooth them out. Just make sure to do this gently to avoid cutting too much! This small adjustment can make a huge difference in your child’s comfort.
2. Flattened Aligner from Biting
It’s easy to accidentally flatten an aligner while trying to seat it in place. Here’s how it happens: when your child tries to bite down to get the aligner to fit, they might inadvertently bend the plastic. Once this happens, it’s often hard to get the aligner to sit correctly again.

How to fix it: If this happens, don’t panic! The aligner isn’t ruined. You can use common pliers (after they are clean of course – preferably with alcohol) to gently reshape the aligner back into place. It’s important to match the bent side to the correct side so it fits properly again. It may feel a little tight at first, but it will work just fine until your next scheduled visit.

3. Cracking the Aligner When Removing It
Another common issue parents see is their child cracking an aligner when trying to take it out. It’s tempting to yank the aligners out by pulling from the front or at an awkward angle, but this can easily cause the plastic to crack or snap. When that happens, stress is placed and the aligners will crack or rip. See the example below.

The right way to remove an aligner: Make sure your child uses both hands—gently placing their index fingers or thumbs at the back corners of the aligner. This prevents putting stress on the front, which is what causes the cracks. If your child has trouble, ask your orthodontist for a handy tool that makes removing the aligners even easier. (At our office, we provide these for free!)
4. Stained Aligners
One of the less fun issues with Invisalign is the potential for stains. Kids (and adults!) who drink coffee, tea, or anything with color or sugar in it can end up with stained aligners. The stain is permanent and you cannot clean it off no matter how much you scrub them! Can you tell which is which below?

The solution: The easiest way to keep aligners clean is to stick to water. Cold or room temperature water is safe, but hot drinks or liquids should be avoided, since heat can warp the plastic. If your child really needs to have a drink, just have them remove the aligners, drink, then brush or rinse their teeth before putting them back in. It’s a simple fix that helps keep the aligners looking clear and working as they should.
