Tooth infection - CS any good for it?

Hello all,

I had a very bad tooth ache this morning and could not eat anything on my right bottom, last molar. I went to see my dentist, he cleaned the teeth and also took an xray. He said that I have an infection in the root canal, although very slight one, I have to take Antibiotics .

My next batch of CS has not arrived yet, so what should I use for both pain and infection. The clove oil did not help me at all. I also like to know if CS is going to help get rid of the infection.

Thank you.
