While there is no exact timeframe of when you should replace your cookware, most nonstick cookware items will remain good for about five years.
However, in general, most people should replace their pots and pans every few years to ensure they're still cooking evenly and efficiently. If you notice your pots and pans starting to warp, discolor, or otherwise show signs of wear, it's probably time to get new ones.
Non-Stick Coating Damage: If the non-stick surface is scratched, peeling, or flaking, it's time to replace it. Damaged coatings can lead to food sticking and may release harmful substances. Warping: If the frying pan is warped or doesn't sit flat on the stove, it can lead to uneven cooking and may not heat properly.
THESE ARE THE 4 MOST COMMON SIGNS THAT YOU SHOULD THROW OUT YOUR PANS: 1. THE BOTTOM OF THE PAN IS WARPED. 2. THE NONSTICK COATING IS SCRATCHED. 3. THE SURFACE IS CHIPPING OFF. 4. THE HANDLES ARE LOOSE AND/OR FALLING APART.
Carbon steel cookware: High-quality carbon steel pans will last a lifetime if used properly. Cast iron cookware: Cast iron pans are similar in longevity to carbon steel pans. They will keep performing for decades, even a lifetime. Ceramic cookware: Ceramic pans typically have a shorter lifespan of less than five years.
Nonstick Pans Do Not Last Forever
A good rule of thumb is to replace them approximately every five years. Look at your pans frequently.
Teflon: Some nonstick pans are sealed with a Teflon coating that can contain PFOA (perfluorooctanoic acid) or PTFE (Polytetrafluoroethylene), which can create toxic fumes when heated. These toxic fumes may cause what is known as “polymer fume fever.” Symptoms include breathing difficulty, fever and sore throat.
Damaged Non-stick Pans Should Not Be Used
While modern non-stick pans are quite safe when used properly, be careful not to use these when the coating is damaged. For example, the coating could be damaged due to long time usage, or abrasion or scratching by hard objects during cooking and washing.
Keep old pots and pans out of landfills by dropping them off at thrift shops. You can drop-off unwanted cookware to any of these nonprofits: Goodwill, The Salvation Army, Society of St. Vincent de Paul, Vietnam Veterans of America and PlanetAid.

Cast iron, steel and tin: Pots and pans made from certain metal materials, such as cast iron or steel, are susceptible to rusting and should typically not be cleaned in the dishwasher. Hand wash these items instead.
The age and condition of the pan can compromise its surface integrity and lead to reactions with acidic foods or leaching of metals into food during cooking. It's important to inspect vintage aluminum pans for signs of wear and tear, including pitting and scratching.

“Glass, like Pyrex cookware, is a safe option,” Perko said. “Cast iron is a safe option if NOT frying or using high-temperature cooking. If you have or can use or purchase stainless steel pots and pans, they are healthier choices for long-term/lifetime use.”
