Your dizziness could be caused by an ear infection, but if it is a dental problem, it is probably inflammation of the TMJ bone in your skull. I have TMJ problems myself, and I sometimes get dizzy, have pain that feels like it is inside my ear, and get headaches and jaw aches from time to time. Either way, you should go to the doctor and have it checked out, but if you have pain in your ears and jaw (and sometimes in your neck), and you feel and popping or clicking in your jaw, you may want to visit a dentist first.
If you do end up having a TMJ problem, don't worry too much about it. It's pretty common. Make sure you see a doctor, just to be sure. If it is an ear infection or something like that, you'll want to get antibiotics as soon as you can so you don't have to suffer with it.
