I noticed the roof of my mouth was sore and a little swollen on the right side earlier this evening.  I was pushing on it a little with my tongue because the pressure stopped the throbbing.  But then all of a sudden the pain spread to my jaw and inner ear.  I went to sleep and was woken up to a horrible throbbing pain in my upper right molars (about 3 or 4 teeth).
Hi, Thanks for asking the query, According to your clinical history is supposed that swelling at the roof of the mouth can be due to decayed tooth Chat Doctor. I would suggest you to visit the Dentist and get the checkup done. Take an x-ray of the upper teeth region, depending upon which a root canal treatment of the affected tooth has to be performed. Start with the course of antibiotics and analgesics. Take lukewarm saline and antiseptic mouthwash gargles. Maintain a good oral hygiene. Hope this helps out. Regards....
