Thanks for asking the query,
Pain can be infection of the tooth that had spread to the periapical tissues leading to formation of abscesses , this pain can be radiating to the jaw and ear .
You need to take x-ray before extraction , better an OPG x-ray.
Since you cannot do the treatment right now take tab amoxiclav
625 mg twice , tab Zerodol
twice all this for 5 days .
Use lukewarm saline gargles 3-4 times , Avoid eating hot and spicy food , use antiseptic mouthwash gargles like chlorhexidine
twice daily .
Root stumps need to be extracted, Depending upon the condition of the front tooth determine the treatment , discuss with your dentist
, It will be better if you go for complte mouth extraction as there are no teeth on the upper arch .
After healing of both the jaws you can go for complete dentures upper and lower.
Hope this helps out.
