Toothache

Tooth aching, thesedays, is distracting me from concentrating on what I have to do.
I usually read out some English textbooks to improve speaking but the ach is so enormous that I can not speak out loudly.
The other problem is the money that would be spent on treating my teeth. I thought my wisdom teeth was aching me but back teeth was the cause of pain.
To treat cavity of the back teeth will cost me a lot of money.
I'm getting worried over the college tution that I have to save during the break. Although amount of money to treal cavity is rather small compared with the tution, I don't want to spent the other things that I've never thought of spending on but tution fee. I have been saving all the money I get from work to cover but I should put money on the things I have not expected to spend on. I feel so terrible about it. How can I cope with this?
