Hi Dear,
Welcome to HCM.
Understanding your concern.
Brief answer - Periapical abscess
As per your query you have
throbbing pain in the area of crown its because of underlying tooth has got build up of bacterial accumulation in that area and due to that bacterial activity pus formation is there and that pus is finding no space to escape and accumulating in that area and putting pressure on
nerve roots and jaws due to which you experience throbbing pain.
I would suggest you to visit
dentist once and get IOPA( X-ray ) of that area done and depending upon extent of underlying infection get
root canal treatment of that tooth done and if infection is too much get that teeth extracted.
After tooth extraction once area will be properly healed you can go for tooth implant or fixed or removable
prosthesis.
Scaling, root planning and curettage of that area should be done to maintain proper cleanliness. Warm saline gargles should be done properly. Brush and floss on daily basis.
Hope your concern has been resolved.
Best Wishes,
Dr. Harry Maheshwari
