Before 20 + Years I Had A Pain In Upper

Before 20 + years I Had a pain in upper last left Tooth ( Dadh ). I showed to a well known dentist who advised me to remove that teeth. Being a familiar doctor , I accepted his proposal. After 20 / 25 minutes & Local anaesthesia in and around the tooth, He started pulling the tooth. Unfirtunately after 2 to 3 trials he was not able to pull out the tooth. Fourth time the tooth broke and half part remained. He went on pulling the tooth to the extent thatmy upper part of mouth upto top of haed was pulled and entire lest side was swolen and I was not able to open my mpith for one month even after medications by same doctor. My bad luck is still went on . Since then Every year 2 to 3 times frequently I have to face the same problem and I have lots of pain. This is because of any hard food is taken or food having sharp edges is consumed. After 15 / 2o days of medications of Antibiotics and painkillers at my own, I am at rest. Previous tooth ( Dadh ) is also removed long back.I have hpertension as well as. S. Creatinine always remains above 2.00. I will be thankfull if you can suggest me a proper medication which can relax me.
