Starting Invisalign or another clear aligner treatment is an exciting step toward a straighter, more confident smile. However, it’s common to experience some discomfort or soreness when you first begin wearing new aligners or when you switch to a new set every couple of weeks. This discomfort is a normal part of the process, as your teeth are gradually shifting into their new positions. Here are 6 helpful tips to get you through those first few days of each new aligner with less pain and more confidence.

1. Use Orthodontic Chewies

Invisalign chewies are small, soft foam cylinders that help your aligners fit more snugly on your teeth. Biting on chewies for a few minutes a few times a day can:

  • Reduce gaps between the aligner and your teeth.
  • Help seat the aligners properly.
  • Ease pressure points by improving the fit.

Consistent use of chewies during the first couple of days with a new tray can go a long way in minimizing discomfort.

2. Switch Aligners at Night

One helpful trick is to switch to a new set of aligners before bed. This way, you’ll sleep through the first several hours when the discomfort is usually most noticeable. By the time you wake up, your teeth will have already begun adjusting to the new pressure.

3. Take Over-the-Counter Pain Relievers

If the soreness is more intense, a mild over-the-counter pain reliever such as ibuprofen or acetaminophen can help. These medications reduce inflammation and ease the ache that comes with moving teeth. Be sure to follow dosage instructions and consult your doctor if you have any medical concerns.

4. Stick to Soft Foods for a Day or Two

Eating hard, crunchy, or chewy foods can worsen tooth soreness right after switching to a new aligner. To avoid extra pressure on your teeth, opt for soft foods like:

  • Mashed potatoes.
  • Smoothies.
  • Yogurt.
  • Oatmeal.
  • Scrambled eggs.

Soft foods can ease your chewing experience until your mouth adjusts.

5. Rinse with Warm Saltwater

If your aligners are irritating your gums or cheeks, try rinsing your mouth with warm saltwater. This can help soothe minor cuts or inflammation caused by friction from the aligners.

You can also ask your provider about using orthodontic wax if the edges of the aligners are sharp or uncomfortable.

6. Be Consistent with Wear Time

It might be tempting to remove your aligners when they feel uncomfortable, but that can actually prolong the pain. Wearing your aligners for the recommended 20 to 22 hours a day helps your teeth adjust more quickly and reduces soreness in the long run.

Some discomfort is a natural part of the aligner journey, especially in the first few days of a new tray. Fortunately, it’s usually short-lived and manageable with the right care and habits. By using chewies, sticking to soft foods, and following your provider’s instructions, you can ease the transition and stay on track for a healthier, straighter smile.
