Do Teeth Aligners Hurt?

Bundles of nerves are tucked into each tooth within your mouth. Aligners apply pressure to nudge your teeth into their proper positions. But each push can irritate your nerves and cause pain.

Your treatment will hurt somewhat, especially when you're swapping out an older aligner for a new one. But mild, over-the-counter medications like aspirin are usually enough to soothe the pain.

Doctors who prescribe Byte also use therapies to ease pain, so you have an even better chance of getting the smile you want without the discomfort you don't.

Why Do Aligners Cause Pain?

While we're brushing and flossing, we're only interacting with a tiny part of our teeth. We may not feel the flick of the bristles or the slide of the floss. But our teeth are wired to send alarm signals when they experience a perceived threat.

A pulp chamber tucked within each tooth holds blood vessels and nerves. Hollow sections in tooth roots allow signals to pass from each tooth to your brain. Aligners can cause those signals to fly.

Wear aligners, and you will:

• Slip clear trays over your teeth. Each tray looks slightly different than your natural smile.
• Receive constant pressure. Each moment you wear your aligners means pushing your teeth into the positions found on the trays.
• Repeat the process. Every week or so, you'll start this process again.

Teeth can and do move in response to pressure. But your body isn't accustomed to a shifting smile. The gentle tugs might seem unusual or wrong to your body, and pain signals tell your brain something is happening.

Pain signals move along the nerves from your teeth to your brain. You might feel something like a dull ache, and it might get stronger when you do things like bite down or bring your teeth together while you talk.

Discomfort is strongest during the early stages of treatment when your teeth are almost constantly moving. In later stages, when only tiny shifts are required, your pain should lessen.

Teeth Aligners shouldn't hurt so much that you can't talk, eat, or handle everyday activities. If they do, you should speak with your team and dig into the cause. But some level of mild pain or discomfort is expected.

Do Aligners Hurt More Than Braces?

Plenty of tools can straighten teeth. Each method works a little differently, but they all cause discomfort. Aligners, however, do cause less pain than braces. Study after study has proven this fact.

Aligners are less painful than braces due to:

Will Your Pain Pay Off?

Aligners work quickly, but most people need to wear them for several months. Some of those days will be at least a little bit uncomfortable. At the end of the process, you'll have an improved smile. Most people are happy with the tradeoff.

Studies of patient satisfaction make this clear. Less than a quarter of people who wear aligners have pain, and the wide majority of them report that they look better when the process is complete.

If you do experience discomfort with aligners, a few self-care steps can help. Try:

• Over-the-counter pain relievers. Aspirin and other simple remedies can help to ease soreness when you're switching to new aligners.
• Cool drinks. Swish water between your teeth after you eat and let the numbing temperature take the pain away.
• Rest. Choose soft foods while your teeth are sore, and avoid very long conversations. Give your jaws and teeth a break until the pain passes.

On days when the pain feels strong, remind yourself that you're caring for your health. Poorly fitting or crooked teeth can lead to oral health issues, including tooth decay, gum disease, or tooth loss. The work you're doing now could keep you healthy later in life.
