I have gotten a massive cavity all of the sudden and I wasn't able to eat, I was super hungry and desperate for anything cause I have a cold sore, a cut gum and a cavity spread all around my mouth and the cavity was the hardest to overcome, I had tried to use my other teeth to eat but food kept getting stuck I had about 2 weeks till my dental kicks in so I am buying time, I washed my mouth before I went and got this and I didn't have an issue getting it in or drying and then I made the mistake of going to dinner as planned I was able to eat my entire meal since I hadn't eaten much in a couple days but by the time I left and got back to my car where I left this it was time to apply more, it DOES say to wait and you really should it last longer if you wait, I have had to re-patch it a few times but it keeps the pain at bay once it dries I have experienced some pain while it is drying with it irritating the nerves but once it is in as long as I avoid gum, fiborus meats like steak and jerky etc, its fine, it tastes kinda gross but its not bad and its a whole lot better then the pain I was in
