Sure Smile aligners are a convenient way to straighten your teeth discreetly, but sometimes a tray may not fit as snugly as it should. When an aligner feels tight, loose, or just won’t seat correctly, it’s natural to worry about whether you need a replacement or if your treatment is at risk. Fortunately, most fitting issues can be addressed without starting over.
Knowing the right steps to take can help you protect your smile and keep your Sure Smile treatment on track.
Check for Common Fit Issues
Before panicking, examine your aligner and your teeth carefully. Some common reasons an aligner might not fit properly include:
- Not fully seating the tray. Sometimes aligners need a little extra pressure at the edges to snap into place.
- Skipping a prior tray. If you missed a step in your treatment plan, your teeth may not be in the correct position for the current aligner.
- Food particles or debris trapped in the tray. Even small bits of food can prevent an aligner from seating correctly.
Try rinsing the aligner and brushing your teeth before attempting to re-seat the tray. If it still doesn’t fit, it’s time to take the next steps.
Use Gentle Pressure, Not Force
It’s tempting to bite down hard to get the aligner to fit, but applying excessive force can damage both the tray and your teeth. Instead, use gentle, even pressure with your fingers along the edges of the aligner. Some patients find it helpful to use a chewies device — a soft, cylindrical tool designed to help seat aligners comfortably — to apply controlled pressure without risk.
Contact Your Dentist
If your aligner still won’t fit, contact your dentist or orthodontist promptly. They can assess whether your current tray is slightly off due to a minor adjustment or if your teeth haven’t moved as planned. In some cases, a small modification can fix the problem, while in others, your dentist may recommend a replacement tray to ensure proper alignment.
Never attempt to force an ill-fitting aligner for an extended period, as it can slow your treatment or even cause discomfort or damage.
Follow Professional Guidance
Your dentist may provide instructions for temporarily skipping a tray, using a replacement, or adjusting your treatment schedule. Following their guidance ensures that your teeth continue to move safely and efficiently according to your treatment plan.
Regular dental check-ins and clear communication with your provider are essential for addressing fit issues quickly and avoiding setbacks in your Sure Smile journey.
A snug, properly seated aligner is key to achieving your desired results safely. Acting early when a tray doesn’t fit can prevent complications and keep your smile transformation on schedule.
