<s>[INST] hello. about a week ago i ha a pretty big cavity filled. a couple days later i started to see signs of an infections and started drinking antibiotics and ibuprofen for my pain. the infection seems to have subsided however now i have a sharp throbbing pain in my tooth that only goes away when i apply ice water under my tongue around that tooth and i have to keep reapplying that ice water or the pain comes back. I cannot sleep at night anymore. i have a dentist appointment friday, is there anything i can do before then to relive my pain? i have already tried ibuprofen aspirin advil and nothing is working! [/INST] Hi, thanks for using Chat Doctor In addition to the oral medication you can try the application of a local anesthetic. There are local anesthetic sprays or gargles that are used for sore throats or lesions of the mouth that may help you. They do not normally require a prescription. You can speak to your local pharmacist to see what is available in your area. In addition, if the pain is so severe, you may need to a stronger analgesic, but these may require a prescription. Medications such as Celebrex, tramadol, codeine may be helpful to you. I hope this helps </s>
