Late october my back bracket came off and without the cement indicating force was applied?

Late october my back bracket came off and without the cement indicating force was applied. It got put back on yesterday. Afterwards i took better care of them and watched what i ate. I ate french fries, watermelon, and lunch of dumplings and cut up meat. Early next morning i discovered the same bracket came off. Still without cement though i do not believe im the cause. My braces have only been on for a one day short of a month a nd really fed up with them. I wish they can get removed.
