Hello, Welcome Thanks for consulting HCM,
I have gone through your query, dont worry , you have mentioned that you are feeling pain in lower right tooth, it can be due to tooth is carious , or may be due to periodontal problem,
numbness and reffered pain in jaw and head ,
For this you should go to
dentist and get investigations IOPA ( intra oral periapical radiograph ) done, to confirm diagnosis ,
For pain you can take Medications one Capsule
Novamox 250 mg twice daily , one Tablet
Paracetamol twice daily , one Capsule vitamin B complex once daily for 3 days , Do warm saline gargle two - three times a day,
Hope this will help you.
Wish you good health.
