no some people have extras. the average is 4 but you can have as little as none and as many as 8. i had a full extra set but they were tiny like little tic tacs because they hadn’t really developed yet!!
i start school on the 31st of this month! but i probably won’t be going the first few days because i just got my 8 wisdom teeth out and my face is very very swollen and it’s really hot where i live and you aren’t supposed to be in the heat after surgery, so i probably won’t be going until next monday. x
