Gel teether busted

I asked my husband to boil some teethers I got in the mail for our daughter and he decided he was going to boil all of her teethers (including a Nuby key ring gel teether) he didn’t know they couldn’t be boiled but obviously it busted and so im wondering can all the other teethers just be washed and reboiled or do they need to be thrown away? I know the gel teethers aren’t good for them to ingest and I just don’t know if it could have gotten on the other toys when it busted.
