IPhone 5 earpiece not working?

Well today I've done my first iPhone 5 screen replacement, which was very bery frustrating. Everything works fine only one problem is the earpiece no longer works. When I removed the front camera I managed to rip one of the copper sensors off, which I'm guessing touches the copper prongs on back of the earpiece, so I've ordered a new front facing camera with the proximity sensors. Will the solve my problem?

I'm thinking so but you may want to call apple just to be on the safe side and not waste your money.
