Achinr teeth they feel lose what's the cause? I haven't been to the dentist in a while

Dental Visit. You're overdue if its been a while. Loose teeth are usually the result of periodontal problems, or grinding. See a dentist before its time for extractions.
See a dentist ASAP. The tooth pain won't go away without treatment and the infection may spread to your jaw, cheeks, sinus and to other areas of your head and neck. You can use Tylenol (acetaminophen) for pain control. See a dentist ASAP for assessment and treatment.
