It is possible to replace the mirror galss without replacing the whole mirror assemble, which is extremely expensive. This is not an uncommon fault with dipping mirrors on many makes of car.

There are a few guides on YouTube. You have to take the whole thing apart and detach the old mirror wiring from the unit and replace it with a replacement. I don't know if you can buy the mirror galss itself new, but the YouTube thing is replacing aknackered mirror glass with a second hand one.
