Will my molars meet again?

I had my top 2 front teeth and the bottom 3 directly underneath bonded due to breakage and damage. The bonding extends the bottom teeth slightly to the height they should have been - they were very worn with exposed pulp. The dentist said to expect my molars not to meet but this should resolve in approx 6 weeks when they readjust and settle. Is this true? I didn’t think molars grew in height so how will the gap resolve? Eating is awkward at the moment and I’m very anxious about it.
