It is strongly recommended that you schedule a prompt visit to your dentist to have the situation with the filling that came out and the exposed soft material properly evaluated and addressed. Avoid any attempts at self-treatment or trying to put the filling back in yourself, as this can further complicate the situation and even lead to more serious problems. Relying on advice from non-professionals online can be risky, and only a qualified dentist can accurately assess the issue and provide the necessary treatment.
