Hi lybrate-user, First of all thank you for approaching Lybrate
for your query. I read through your query. In my opinion the xray
of the tooth and the clinical picture can tell us more about the condition. So can you please sent the picture of the tooth from inside the mouth (clinically) and the xray of that tooth so that we can reach a better conclusion. Pain
can be due to infection
. So the injection will not work. So it should be done once antibiotic
course is given. So please come back to me with the clinical picture of the tooth and xray of the teeth so that I can help you more. Hope you have got the answer for your query. Keep a happy and calm mind. These can be best medicine for any disease. Have a healthy day. Thank you.
