I have 28 teeth in my mouth, and WebMD said the proper amount is 32. And on the bottom left side, in the far back, there is a hole in my gums revealing another tooth. I did research and am so confused because everything I find online says something different. A lot of people refur to wisdom teeth as third molars, and a lot say they are two different things. I went to the ER because it was swollen and painful and I said to the Dr "I think my wisdom teeth are coming in" and she said "NO, its your third molars. So she is claiming they are two different things as well. I am so confused because I can't figure out whether my wisdom teeth are coming in, or if I have four molars still under the gums that shouldn't be.
