My teeth in the very back on my top row at very loose and hurts and gives me headaches whats should i do ?

See your dentist: You have dental issues which should be addressed and reversed ASAP. MUCH OF THIS CAN BE FIXED. GOOD LUCK

Oral Infection?: I understand your distress. Thank you for informing, “Teeth -very loose and hurts and gives me headaches” Please see a Dentist as soon as possible for: • Examination • Diagnosis • Extraction? • Follow up • Antibiotics • Oral Hygiene Your Health is Precious!

Agree with Dr. M: It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. You may take acetaminophen for pain, no more than 4 g/day, no alcohol. It would be prudent to see a dentist at your earliest. Wish you good health!
