5 year old, Totten tooth.

I am embarrassed to say, but my 5 year old has a Totten tooth. It started as a cracked tooth, and is now rotten to the gum line in the middle. She is scheduled to have it removed but they can't take it out until august 30th. Will she be ok until then or should I try and demand a closer appointment, though I'm honestly not sure there is a closer appointment as her dentist is extremely booked all the time. It is the only one that takes her insurance, so taking her somewhere else isn't an option. I'm just super worried it's going to get infected.
