Does Touch ID Decay Over Time?

Although not a new technology by any means, fingerprint scanners have historically been hamstrung by issues that have caused their sensors to degrade relatively rapidly, no longer being able to correctly read a fingerprint after only a few months.

When Apple introduced Touch ID with the iPhone 5s, they claimed to have solved that problem. Protected by nigh-indestructible Sapphire Glass, the Touch ID sensor is supposed to be able to read the curves and contours of your fingerprints at a resolution of up to 500 pixels per inch. But could Touch ID be just as susceptible to degradation issues over time as previous biometrics solutions?
