What causes upper molar toothache?
Patient: I have tooth aches that vary in intensity when I change positions. The tooth is an upper molar on my left side. Pain increases when I lay down and decreases when I sit upright. I went to my Dentist about 2 weeks and he filled a cavity I had in the wisdom tooth next to the molar giving me pain. The pain still exists. What  do you think is going on? Doctor: Hi..Thanks for the query..Your symptoms are pointing towards dental abscess formation due to deep Infection in tooth..When infection reaches below root tips of the tooth there is pus formation and on lying down the pressure increases causing increased intensity of pain..So my suggestion is to consult an Oral Physician and get evaluated..An x ray should be done so that exact condition of tooth can be ruled out..If the decay is such that tooth can be saved then Root canal treatment can be done under antibiotic cover..If the decay is deep extraction is advisable..For now start taking antibiotics like Augmentin and anti inflammatory painkillers like Ibuprofen and do cool compresses over the cheek..Hope this helps..Regards .
