Wisdom teeth extraction

Last month, i have my left side wisdom teeth extraction at Kah Kah Dental Clinic, ss2, Petaling Jaya. The operation need around 1 hour plus...
This is the bottom one, to extract it, i need to pay RM500!!

Upper and bottom wisdom tooth, to pull the upper side tooth, it cost much more cheaper if compare to bottom one, RM80.. Why the range is so wide? Its because the upper side tooth just take about few minutes to extract out but the bottom one used up to an hour....

I lost a lot of blood for the operation... Total cost:

Bottom wisdom tooth RM500
upper wisdom tooth RM 80
X-ray x 2 RM 50
Medicine RM 50

Total RM680

And i plane to extract my right upper wisdom tooth soon, because it started pain already..
