Hi.
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain in case if you have pain in any of the tooth that is filled and you are taking antibiotics for it but the pain will not be relieved as it seems that the nerves have been exposed during making a cavity in the tooth to remove decay and retain the filling material and the
nerve irritation and inflammation is the cause of pain..
For this consult your dentist again and get an
x ray done and in case if the nerves are exposed removal of the filling followed by
Root canal treatment can resolve the problem..
The blood in saliva can be due to infection in the gums causing inflammation of the gums and bleeding which is evident through saliva..
While in case if there is blood spots through nostrils it is possible that due to hard
sneezing there is some rupture of minor blood vessels leading to blood spots..
The other thing that is possible is that your blood pressure is rising leading to bleeding or it can also be a side effect of certain medicine that you are taking..
You should
consult a dentist and get evaluated and also get the blood pressure checked..
In case if the blood pressure is high consult your treating physician so that he can alter the doses of the medicine as per the requirement..
In case if
allergic reaction is found change of the antibiotics can help..
Hope this information helps..
