Starting your journey with clear aligners like Invisalign is exciting! Your dream of a straighter smile is becoming reality. However, it’s normal to experience some discomfort when you first start wearing a new set of aligners. This temporary soreness is a sign that your teeth are moving, but that doesn’t mean you have to suffer through it. Here are several tips to help ease the discomfort and make your transition to each new aligner tray as smooth as possible.

Use Orthodontic Wax

Sharp edges or rough spots on a new aligner can irritate your gums, cheeks, or tongue. Orthodontic wax, available at most drugstores, can be applied to the edges of the aligners to create a smoother surface. Simply roll a small piece of wax between your fingers and press it onto the offending area of the aligner. This can significantly reduce irritation during the first few days of a new tray.

Switch Trays Before Bedtime

A smart strategy is to start wearing a new set of aligners right before you go to sleep. This gives your mouth several hours to adjust while you rest, so you can sleep through the initial tightness or pressure. By the time you wake up, the most intense part of the adjustment period may already be behind you.

Take Over-the-Counter Pain Relievers

If your teeth feel sore or sensitive, a mild pain reliever like ibuprofen or acetaminophen can help. Be sure to follow the dosage instructions on the label and check with your dentist or doctor if you have any health conditions or are taking other medications. Usually, you only need pain relief for the first day or two after switching to a new aligner.

Use a Cold Compress

Applying a cold compress or ice pack to your cheeks can help reduce inflammation and ease discomfort. Do this for about 10 to 15 minutes at a time, with a cloth between your skin and the ice pack to avoid irritation. This is especially helpful if the soreness is concentrated in certain areas of your mouth.

Stick to Soft Foods

When your teeth are sore, biting into hard or crunchy foods can be painful. Stick to soft foods like smoothies, yogurt, mashed potatoes, pasta, or soups during the first few days with a new tray. Avoid chewing gum or sticky foods that might cause additional pressure on sore teeth.

Wear Your Aligners Consistently

It might be tempting to take your aligners out to relieve the pressure, but doing so can actually make the discomfort last longer. Consistently wearing your aligners for 20 to 22 hours per day helps your teeth adjust faster and reduces the duration of soreness.

Discomfort from new aligners is completely normal and usually subsides within a few days. With the right strategies, like switching trays at night, using pain relievers, and sticking to soft foods, you can manage the soreness and stay on track with your treatment. If the pain is severe or lasts more than a few days, don’t hesitate to contact your orthodontist. Your comfort matters, and help is always available to ensure your path to a straighter smile is as smooth as possible.
