Does the iPhone 5 screen get dents easily

I placed my iPhone in my pocket, and I was leaning on a table. My pocket was leaning to the edge of the table, which means that the sharp edge of the table was pressurizing the iPhone in my pocket. Will the screen curve inwards or have any dents because the table was pushing on it? I see no dents, but I'm afraid of unnoticeable dents.

The glass on the iPhone is fairly strong, and more likely to crack than dent/bend under extreme pressure. So no worries for dents.
Also, just try to put the phone in your pocket with the screen facing to your body. That's what I do, never had any issues.

The screen itself is made of an incredibly strong glass that is difficult (but not impossible!) to break. The construction of the iPhone 5 makes it less likely to break than previous iPhones, though obviously a serious enough fall will break any phone. The actual metal around the edge is a little softer, so it may dent a little with a hard drop, but because it's softer it's less likely to transfer the shock to the glass and shatter it.

In terms of what you are talking about, no the glass is very unlikely to curve or warp without heat. The kind of pressure required for that would shatter the glass first.

It gets dents just as easily as any phone. Which is pretty easily. I don't think you should worry much about 'unnoticeable' dents though.

No you'll be fine, although I'm in the habit of always carrying my iphone in my pocket, screen facing in… I do that naturally all the time now, that way you don't bump into a sharp corner walking or something like that where it could hit the screen hard.
