Dental Wax
I broke a part of a tooth off and my dentist is only doing emergency extractions.  I don't want the tooth pulled so I needed something to keep food out of the "hole".  Unfortunately I just didn't get the hang of this.  I warmed it up but it just didn't want to stick to the tooth.  Felt like I couldn't eat or drink with it on the tooth so I gave up.  Tooth doesn't hurt anymore , still has the hole but I'm just going to have to deal with a hole.
