Yes, it is possible for a dent to reappear after Paintless Dent Repair (PDR), but it’s not common. This might occur if the repair wasn’t done correctly, the dent was too severe to be fully repaired with PDR, or if the vehicle is subjected to similar impacts or conditions that caused the original dent. It’s essential to have PDR done by a skilled professional to reduce the risk of the dent reappearing.
