Can Invisalign cause headaches?

Can Invisalign cause headaches? It can for some people, usually briefly, and knowing the cause makes it easier to fix.

Short answer: some people notice a mild headache or jaw soreness in the first days of a new aligner, usually from pressure on the teeth or from clenching on the plastic. It should ease within a few days. Headaches that persist or are severe need to be checked.

Why it can happen

• Pressure from a new aligner as teeth begin to move
• Clenching or grinding on the aligners, which tires the jaw muscles
• An aligner that isn’t fully seated and changes how the teeth meet

What helps

• Switch aligners at bedtime.
• Notice clenching during the day and relax your jaw: lips together, teeth apart.
• Use warm compresses on tight jaw muscles.
• Over-the-counter pain relievers can help if they are safe for you — follow the label.

When to call

Call us at (305) 512-0066 if headaches last more than a few days, your jaw clicks, locks or hurts to open, or an aligner doesn’t fit. If headaches are severe, sudden or come with other symptoms, see your physician — not every headache is from the aligners.

Already in treatment with us? Mention any headaches at your next checkup, or request a visit sooner. We also look for signs of clenching at every exam and cleaning.

How long can Invisalign cause headaches?

When pressure is the cause, headaches usually follow the same pattern as tooth soreness: strongest in the first day or two of a new aligner, then fading. If a headache shows up on the days you switch aligners and eases as the aligner settles, pressure is the likely link.

Clenching, grinding and your jaw joint

Some people bite down on new aligners without noticing, especially when concentrating or asleep. That muscle work can cause a tension-type ache in the temples or jaw. Cleveland Clinic lists headaches among the symptoms of TMJ disorders and teeth grinding among the causes. Tell us if your jaw clicks, locks or feels tired in the morning.

Other causes worth ruling out

• Not drinking enough water during the day
• Skipped meals while you get used to removing aligners to eat
• Poor sleep
• Sinus problems, eye strain or other medical causes

If your headaches don’t line up with aligner changes, the aligners may not be the cause. A physician can help look at other reasons.

What we can adjust

We can check the fit of your aligner, smooth an edge that rubs, look at how your teeth meet and, if clenching is a concern, talk about ways to protect your teeth after treatment. Learn more on our Invisalign page.

When a headache needs medical attention

See a doctor promptly for a sudden, severe headache, or a headache with fever, a stiff neck, vision changes, weakness or confusion, or one that follows a head injury. These aren’t aligner problems.

Habits that help prevent aligner headaches

• Drink water throughout the day, and take aligners out for anything else.
• Eat regular meals; plan time to remove and clean your aligners.
• Keep wearing aligners consistently; long breaks make each return feel tighter.

Should I stop wearing aligners if I get a headache? No. Taking them out often makes the next fitting tighter. Use the tips above and call us if it doesn’t ease within a few days.

Keep a simple headache log

For a week or two, note the day you switch aligners, when headaches start, how long they last and what helps. Bring the notes to your next visit. A pattern that matches aligner changes points to pressure or clenching; no pattern points to another cause your physician should check.
