Has anyone encountered melted pigeon cooling teether in steriliser, can steriliser still be used? My mum sterilised the teether, milk bottle and sprout cup together! Is steriliser still safe to use?

Are you still using the same bottles? Im worried now that ive just melted my baby's pigeon teether too. Im afraid to use it as im thinking of harmful contents and all. Tried searching for the teether's content but couldn't find it in their website
