The best solution if the coating on your non-stick pan scratches off is to throw it away and purchase a new one. There is a possibility that non-stick coatings may contain chemicals that leach into food and harm your health if consumed. The use of non-stick pans for long-term use is not recommended by me; I prefer stainless steel or cast iron pans, and I typically do not use non-stick pans for more than two years.
