Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain
high fever and throat pain after tooth extraction seems to be due to
septicemia that is the entry of bacteria into the blood circulation from the extraction site.
The body's defence mechanism tries to fight with the infection and there is rise in body temperature which is a sign that body is defending infection..
Nothing to worry, you can give him
Tylenol for reducing fever and do
cold sponges over the forehead and body..
For throat ache make him do warm saline gargles and steam inhalations.
If he is not advised to take antibiotics
amoxicillin can be taken..
If the fever does not resolve or keeps recurring consult a Generl Physician and get him evaluated..
Hope this information helps..
Thanks and regards.
