Can Fingerprints Go Away?
Fingerprints, while remarkably unique, are not permanent. They can change or even disappear under certain circumstances, though they usually regenerate.
-
Deep Damage: The only time fingerprints don't regenerate is when the damage goes deep enough to affect the skin layer responsible for their generation. Even then, a fingerprint scan might still be possible as most ridges usually remain. (Source: The only time fingerprints don't regenerate is when damage is deep enough to affect the generating layer of skin. Even with this type of damage, however, you can almost always still get your fingerprints scanned, as most of the ridges will still be intact.28-Jul-2022)

Skin Conditions: Some skin conditions can affect fingerprint clarity.

Severe Burns or Cuts: Deep burns or cuts to the fingertips can disrupt fingerprint patterns, but they often regrow with the original pattern.

External Factors: Fingerprints left on surfaces degrade over time due to environmental factors like sun exposure, rain, and even cleaning agents. Their longevity depends on the surface and conditions. (Source: In general, a fingerprint can remain visible for days, weeks, or even months, depending on the circumstances... Quora)
Fingerprint Regeneration
In most cases of minor damage or wear, fingerprints will regenerate, although the exact pattern may not be entirely identical to the previous one. The regeneration time varies depending on the extent of the damage.
Conclusion
While fingerprints can be affected by various factors and temporarily disappear or become less clear, the underlying structures responsible for their formation often enable regeneration.
