How long do wormholes last?

Could you kindly enlighten me on the duration of wormholes? I've heard various theories about their existence and stability, but I'm particularly interested in understanding how long these hypothetical bridges between two distant regions of spacetime might persist. Is there a specific lifespan associated with them, or do they have the potential to exist indefinitely under certain conditions? Your expertise in this field would be greatly appreciated in helping me understand this fascinating concept.
