How Should Aligners Fit? Signs of Good and Bad Fit
By Dr. Muneeba (BDS), Orthodontist at Aligno Karachi
Proper aligner fit is essential for effective treatment. Learn what a well-fitting aligner looks and feels like, how to identify tracking issues, and what to do if your trays are not sitting correctly on your teeth.
Signs of a Good Fit
- Aligners sit flush against your teeth with no gaps
- Edges follow the contour of your gumline
- You feel even pressure across multiple teeth
- The aligner clicks into place securely
Signs of a Bad Fit
- Visible gaps between the aligner and teeth
- The aligner lifts away from certain teeth
- Excessive pain in one specific area
- The aligner feels loose or falls off easily
What to Do About Tracking Issues
Use aligner chewies for 5-10 minutes after insertion to improve seating. If gaps persist after 3 days, contact your Aligno orthodontist. Minor tracking issues can often be resolved without changing your treatment plan.
Contact your orthodontist if you have concerns about your aligner fit.
