Listen my friend Bodmas, There is one another way out .i understand you situation. In everycity , there might be some vietnamese docs , they are dentist or dental assistant that do this kind of stuff.their office are like dirty and all and for a sec you will think they gonna kill you instead of operate on you.This is risk and if it is not too major like you need operation , then they do these sort of stuff .They are 80% cheaper than your ordinary docs. The risk factor is there.Here man one hand you one to save money other hand you have to take a risk. How much of risk can you take ? i am not adentist but if you go for extraction is lower tooth , i suggest you do not take risk.The risk are higher.The nerves are connected and deeper.The upper one is relatively less risk than lower. well ,man if you can wait and suffer so much pain then wait.But this fu(king tooth when it hurts they are hell of pain. PAIN LIKE FU(K :p HEHEHE.I know this !!!
