Wearing clear aligners can be a convenient and discreet way to achieve a perfect smile, but it’s often accompanied by minor side effects. Many people experience mild to moderate pain during treatment, and knowing what to expect can make a huge difference in your overall experience.

A typical side effect is aching—especially when you move to the next tray. This occurs because your teeth are being gently moved into optimal spacing. The tension can cause mild soreness, usually lasting 2–4 days. To ease this, you can swish saltwater solution, which helps reduce inflammation. Analgesics like ibuprofen or acetaminophen, taken as directed, can also provide relief without interfering with your treatment.

Another issue is chafing on inner cheeks. Sometimes, the rough rims can rub against soft tissue, causing blisters. If this happens, you can use a emery board to carefully buff any burrs on the aligner. Always clean the aligner after filing to eliminate debris. If the sores don’t heal, contact your orthodontist—they may be able to adjust the aligner to protect tender spots.

Reduced saliva and excess drooling are also typical during adaptation. Your mouth needs time to get used to the presence of aligners. drinking plenty of water helps with lack of moisture, and within days, your body will self-adjust saliva levels. Chewing sugar-free gum can also help reduce dryness if discomfort becomes persistent.

A number of wearers notice slurred speech at first. This is expected and usually resolves in 7–14 days. Read aloud daily—singing along to your favorite songs can help your oral muscles adjust more efficiently. Don’t stay silent just because it feels strange. The consistently you keep your aligners, the more comfortable they become.

Lastly, skipping hours for the recommended minimum 20 hours can lead to setbacks. If you miss several days, don’t double up trays in one day. Instead, go back to your previous set for 2–3 extra days to let your teeth re-acclimate, then progress to the next set. Regular wear is essential to stay on track.

Always keep your aligners clean to prevent oral odor and plaque accumulation. Brush them gently using a gentle-bristled brush and mild soap or apply a specialty rinse. Never use hot water—it can damage the aligner material.

If discomfort becomes severe, persists beyond 7 days, or is paired with ear pressure, contact your orthodontist. These could be signs that your treatment plan needs adjustment. Nearly all common side effects are transient and manageable with a little patience. With time, what once felt strange will become your daily routine.
