Does Invisalign Hurt? Here’s What You Need to Know

If you’ve just started Invisalign or you’re thinking about beginning treatment, theres a good chance that you have thought “I wonder if Invisalign hurts, Is it painful?" The honest answer? It can at times but it’s definitely worth it for that new smile of yours.

So let’s try to explain why Invisalign can feel uncomfortable, what kind of pain is normal and when you should be worried, how long the pain lasts, and what you can do to relieve it.

It’s different for everyone. Different people experience Invisalign discomfort in different ways, but here’s what most describe:

• Pressure: A tight feeling on your teeth when you first insert new clear aligners.
• Soreness: Especially when chewing during the first couple of days.
• Mild aching: A dull ache in the gums or jaw that fades quickly.
• Edge irritation: Sometimes the edge of the tray can rub against your tongue or cheeks.

All of this is completely normal and most of the time, reduces as treatment progresses.

The first 24–48 hours after switching trays 🦷

This is when the pressure is most noticeable, especially with your very first set. It’s probably going to feel like a dull ache or a general soreness across your teeth and gums. Over time, your mouth gets used to the aligners, and the pain becomes more bearable.

If your aligners are causing discomfort, here are some simple remedies:

✅ Switch Aligners at Night

Make sure to change your trays right before bed. This allows your teeth to start adjusting while you sleep, so you can avoid the most painfull parts.

✅ Use Cold Compresses

Use an ice pack or cold towel and press it against your jaw for 10 to 15 minutes to reduce swelling and help with pain.

✅ Take Pain Relievers

Ibuprofen or paracetamol are a great way to reduce inflammation and soothe discomfort. Always follow the recommended dosage.

✅ Use Orthodontic Wax

If the sharp edges of your Invisalign are rubbing against your gums, orthodontic wax can be a great product to reduce this. Apply to shop edges of your aligners.

✅ Stick to Soft Foods

In the first 48 hours, avoid crunchy or chewy foods. Soups, smoothies, yoghurt, and mashed potatoes are your best friends.

✅ Stay Hydrated

Dry mouths are more prone to irritation so sip water regularly to keep your mouth healthy and hydrated.

✅ Try StarMintz Clear Aligner Mints
