How to Prevent and Fix Common Clear Aligner Problems (Pain, Fit Issues, Speech Changes)

Clear aligners like those from Smileie are a modern, convenient solution to straighten teeth without the bulk of metal braces. But while they’re designed for comfort and simplicity, users can sometimes face minor challenges such as clear aligner pain, fit issues, or even temporary changes in speech.

The good news? These problems are usually easy to fix or even prevent altogether. In this blog, we’ll walk you through the most common clear aligner problems, why they happen, and what you can do about them.

1. Clear Aligner Pain or Discomfort

Why It Happens:
Some soreness is expected, especially when starting a new aligner tray. The pressure on your teeth is a sign that your aligners are working to shift your teeth into place. However, prolonged or sharp pain might indicate something else, like a rough edge or a tray that doesn't fit properly.

Prevention and Fixes:

• Follow your wear schedule strictly: Switching to a new tray too early can increase discomfort.

• Use orthodontic wax: If the edges feel sharp or rough, wax can create a smooth barrier between the aligner and your mouth.

• Over-the-counter pain relief: Mild discomfort can be managed with ibuprofen or acetaminophen during the first 1–2 days of a new tray.

• Check for fit issues: If the tray doesn’t seem to seat properly, reach out to your provider.

• Switch at night: Start wearing a new aligner tray before bed to “sleep through” the initial soreness.

With Smileie, your treatment plan is custom-designed by licensed dental professionals to ensure optimal fit and comfort. Our team is also available to assist you in case you experience continued discomfort.

2. Poor Aligner Fit

Why It Happens:
A poor fit can result from not wearing your aligners long enough each day (you should wear them for 20–22 hours daily), skipping trays, or a manufacturing defect.

Signs of a Poor Fit:

• Gaps between your teeth and aligner

• Trouble fully seating the aligner

• Aligners popping out when speaking or eating

How to Fix It:

• Use chewies (aligner seaters): These help push the aligner into place for a snugger fit.

• Never skip trays: Always follow the prescribed order of aligners to avoid disrupting your treatment.

• Consult your provider: Smileie customers can contact our team if fit issues persist, we can review your treatment progress and advise if any adjustments are needed.

A well-fitting aligner is key to effective treatment, and at Smileie, every set is crafted based on your 3D scans to minimize such issues.

3. Speech Changes or Lisping

Why It Happens:
Clear aligners sit over your teeth, and during the first few days, they may slightly interfere with tongue movement, especially when pronouncing "s" and "sh" sounds. This is usually temporary.

Tips to Adjust:

• Practice speaking aloud: Read out loud or repeat difficult words to help your tongue adapt faster.

• Stay consistent: The more consistently you wear your aligners, the faster your mouth will adjust.

• Be patient: Most people notice improvement within 2–3 days.

Remember, any initial speech change is usually temporary. Smileie aligners are designed to be ultra-thin, making the adjustment period smoother than bulkier alternatives.

4. Dry Mouth or Increased Saliva

Why It Happens:
Your mouth may initially interpret the aligner as a foreign object. Some people produce excess saliva, while others feel dryness.

Solutions:

• Stay hydrated: Sip water throughout the day.

• Avoid caffeine and alcohol: These can worsen dry mouth.

• Practice oral hygiene: Rinse aligners regularly and brush your teeth after eating.

These side effects usually balance out as your body gets used to the aligners.

5. Difficulty Removing Aligners

Why It Happens:
New aligners fit snugly, which can make them tricky to remove at first.

Tips:

• Use an aligner removal tool: Smileie aligner kits include tools to help you safely take your trays out.

• Start from the back molars: Gently lift one side first.

• Avoid using sharp objects: This can damage your aligners or hurt your gums.

Being gentle and consistent with removal helps preserve the life of your aligners and protect your teeth.
