Normal lifetime of non-stick teflon pans Questions such as Are Non-Stick Bread Pans Destined to Fail? conclude that non-stick pans do not last forever, especially cheaper ones. I am trying to find some information that allows me to quantify this to some extent.

I normally use teflon non-stick pans some 3 times a week. I only use wooden and plastic tools on them, never metal ones. For some dishes, however, it is necessary to exert some rather punctual pressure (through the food) on the pan's surface, as well as dishes that require quite some oil (sometimes added in between, i.e. while the pan is heated) even in non-stick pans in order to not stick.

In my experience, my teflon pans live for some 3 to 4 years before they start showing some minor, but visible blank spots of one or a few mm² where the teflon has disappeared. Which is when I start considering looking for a new pan.

At my usage rate, is this within the expected lifetime range of teflon pans? or, asked more generally, What is the approximate expected lifetime for teflon-coated non-stick pans?
America's Test Kitchen says that good quality nonstick pans last them about six months.

They're presumably cooking with them several times a day, so if you use it once every couple days, and are as good as they are about not doing things that'll damage the coating, you might get a few years. So your experience sounds roughly normal.

As another data point, they also quote the Cookware Manufacturers Association: "'If you get a year to a year and a half of life out of [a new nonstick pan], we think you got a pretty good deal.'" That's coming from people interested in selling pans, possibly not talking about the best quality, and with experience based on typical less-careful usage, so I'm not surprised they gave a lower number.
