Insufficient wear time — consistently below 18–20 hours daily — means teeth do not move as planned. Each aligner tray is engineered to achieve a specific amount of tooth movement over 7–14 days. When wear time is inadequate, the tooth does not complete its planned movement before you advance to the next tray. The next tray then does not fit correctly, either sitting loosely or creating excessive pressure in the wrong places.
The consequences: your orthodontist may need to order refinement trays to complete the movements that were skipped, extending your total treatment duration. In some cases, the patient needs to go back to a previous tray until the movement is complete before advancing. Neither outcome is a disaster — but both add time and cost that are entirely avoidable.
If you realise you have been under-wearing your trays, the right approach is to tell your orthodontist at the next review. Trying to hide it and push forward to the next tray anyway creates compounding problems. Dr. Jebu will reassess fit and movement before advancing treatment — that check exists specifically to catch these situations.
