Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have toothache it can be due to food lodgment, Periodontal problem Pocket formation may be there, or toothache can be due to carious tooth.  You do is consult dentist and go for investigations done IOWA X-ray if you have periodontal pocket then go for Curettage if you have caries then go for Restoration.  Do warm saline gargle two - three times a day.  You can take analgesic, One tablet Diclofenac sodium twice daily for symptomatic relief. Hope this will help you. Wish you good health.
