Save the Teeth

MY CONDITION :
There is a swelling area at the lower jaw of my mouth.
It grows larger these months and sometimes squeezes with pus.
I finally went to a dentist and he told me that it is dental infection to my teeth.

TREATMENT ADVICE :
Besides the treatment to the swelling area, the dentist told me he will need to perform Root Canal Therapy and Restoration in order to fully cure the infection problem. There is also another crack found in the left front tooth.

I still have not performed the treatment since I do not have enough money to handle this. I don't feel pain to the swelling area and the other oral parts at the moment, so this could buy me some time to raise fund first and see what I can do.

MY BACKGROUND :
Growing up in an un-wealthy, working class family in Hong Kong, I was graduated for not long and could not be able to save money for such expenses. My parents are old and they have their own medical expenses too, so they could not support me too much.

Please help me to restore the health of my teeth. I would appreciate any amount of donation. Thank you.
