I had a lower molar removed yesterday afternoon, numbness subsided after approx 5 hours, took paracetamol and ibuprofen but did not experience any pain. Slept ok, propped up with an extra pillow. Tooth was broken but came out cleanly and easily. No pain at extraction site. I ate food last night once normal feeling had resumed and drank plenty of water. Now i feel hot and lightheaded. Is this normal?
