Me and my sister in law were talking about dreams and a dream came up that we both have had and still have every now and then.......In my dream im not really sure what im doing but i bite down and all my teeth shatter.....like completly break...all of them. I usual wake up checking if my teeth are still there. I know quite a few people have this dream but the meanings that ive read give a variety of meanings. I would really just like to know a specific answer on why this dream occurs.

Have a look at this thread, dating from some 8 months ago:
