the condition you had written in the query is really critical.
you need a dentist
and proper treatment.
now a days the dentistry is completely painless. please do not have any fear in your mind.
just visit and get the proper diagnosis and treatment.
extraction is one of the alternative but not for all.... with so much of advancements in dentistry now a days, it is quite easy to save a tooth.
there is no other way out, by taking palliative treatment you are advancing yourself to the extraction of tooth.
I am sure if you visit dentist once you will get the confidence and trust.
Best of luck.
