How Much Will My Teeth Hurt When Using Invisalign Clear Aligners?

In this post, our Thornhill dentists explain why your teeth may hurt a bit during treatment with Invisalign clear aligners, and how you can manage any pain you experience.


You may have heard that pain in your mouth or sore teeth are common during treatment with Invisalign clear aligners? Though this is true, you shouldn’t allow it to scare you away from this orthodontic treatment option.

Remember the last time you pushed yourself to complete another 10 pushups or walk for just a half hour longer and felt a bit sore after? It's the same idea here – as your teeth gently shift into their prescribed positions to help you achieve a straighter smile, they may feel a bit sore while the clear aligners work.

Today, we'll review challenges you may face during and following treatment with Invisalign, and how you can deal with the effects. 

How much will my teeth hurt, and why?

Though not everyone feels soreness or pain during the treatment process, many will; some describe it as a light pressure on their teeth on the first day they switch to a new clear aligner tray. During treatment with Invisalign, your teeth will move only about .2 millimetres from the first day to the seventh that you wear a new clear aligner tray. 

Invisalign trays are made of smooth plastic - no wires (like traditional braces have) to poke or prod sensitive places in your mouth, which can sometimes cause irritation. You may also notice a little more adaptability in this plastic compared to other more stiff plastics, so Invisalign pain should be minimal. Plus, your clear aligners will be custom-made to fit your smile. 

Home Remedies for Invisalign Clear Aligner Pain

If you do feel a bit of pain while your teeth adjust to their new positions, there are some home remedies you can try:

Switch to your new aligners at night.

Since you’ll be sleeping, night may be your best time to switch to your new aligners. This way, your mouth will have the next 8 hours or so to get used to them and any discomfort, pain or tenderness you feel may disappear by the time you wake up.

Use dental wax.

Are your teeth or gums feeling painful as your clear aligners realign your teeth? Dental wax may help. Apply a tiny amount between your teeth and your aligners, or on any areas that are very tender or sore. The wax will act as a cushion on your teeth as they adapt to your aligners.

Rinse with warm salt water.

Your mouth sores may be soothed with a swish of salt water. You only need ½ teaspoon per 1 cup in warm water. Try this every few hours for 3 to 4 days, keep diligently flossing, brushing and practicing excellent at-home oral care, and see if this works.

Eat cold foods.

Some patients report that indulging with a 100% fruit Popsicle or cold ice pop helps their gums to feel better after they switch aligners. Don’t forget to remove your clear aligners before you eat.

Take an over the counter pain killer.

If all else fails, over the counter painkillers can be just what you need to help alleviate mouth pain due to a new set of clear aligners.

Apply an ice pack.

Similar to a cold Popsicle, an ice pack, towel moistened with cold water or a cold compress can help to soothe a sore mouth and reduce inflammation.

See your dentist regularly.

One of the most important things to keep doing as you progress through your treatment with Invisalign clear aligners is to keep seeing your dentist regularly - every four to six weeks.

They will check in on your smile and your progress, and answer any questions you may have about whether what you are experiencing is normal, and provide advice.

Another bonus: clear aligners usually don't require adjustments, so your dentist won't need to tighten them regularly like would be required with traditional braces, which may cause some pain.
