You've got your first aligners. The first few days feel strange: tight teeth, a new lisp, maybe more saliva than usual. It's all normal, and most of it passes within a week. Here's what to expect and how to make it easier.
Days 1–3: pressure and tenderness
Your teeth will feel tight and may be tender when you bite. This is usually the most uncomfortable part of the whole treatment. Soft foods help, and many people take an over-the-counter pain reliever on day one. See what aligner pain is normal.
A lisp and extra saliva
Your tongue has less room and needs to adjust, so "s" sounds may whistle. Your mouth may also produce more saliva. Both usually fade within days. Talking and reading aloud speeds it up. See aligners and a lisp.
How to put aligners in
- Wash your hands and rinse the aligners.
- Line the aligner up over your front teeth and press gently.
- Push it onto your back teeth with your fingertips until it clicks into place.
- If your provider gave you chewies, bite on them gently for a few minutes to finish seating.
Don't bite hard to snap aligners on. That can crack them.
How to take aligners out
- Start at the back molars on one side.
- Use a fingertip to gently ease the edge off the inside of the tooth.
- Work slowly around to the other side, then lift it off the front teeth.
It gets much easier after a few days. Attachments make aligners grip harder, so be patient.
Habits to build this week
- Case, never napkin. Most lost aligners start at a restaurant table.
- Water only with aligners in. See eating and drinking with aligners.
- Clean the aligners twice a day with a soft brush and cool water. See how to clean aligners.
- Brush before putting them back in after eating.
- Track your hours from day one, so you learn what a 22-hour day actually feels like.
- Take "before" photos now. You'll want them later.
When to call your orthodontist
- Pain that gets worse, or sharp pain in one tooth that doesn't ease after a few days
- An edge that cuts your cheek or tongue
- An aligner that won't go on or is clearly not fitting

The bottom line
The first week is the steepest part of the learning curve. By the end of it, most people have adapted to the feel, the sound, and the routine. Build good habits now and the rest of treatment gets much easier.
Frequently asked questions
Is it normal for new aligners to hurt?
Yes. Pressure and tenderness in the first days are expected and a sign the aligners are working. Sharp or worsening pain should be checked by your orthodontist.
How do I take out aligners without breaking them?
Start at the back molars on one side, gently ease the aligner off with your fingertip, then work around to the front. Avoid pulling from the front teeth or using sharp objects.
Can I eat normally in the first week?
Yes, with aligners out. Soft foods are more comfortable for the first couple of days while teeth are tender.
Why am I producing so much saliva?
Your mouth treats the aligners as something new. Extra saliva is common in the first days and usually settles within a week.
