What Causes Fever And Headache After A Dental Procedure?

My daughter had a dental procedure done on Thursday that required the use of laughing gas. That same afternoon she stared to experience headaches and later that evening a fever. I called the dentist and they had her go back in saying that it could be the filling, so they fixed it. She continues to have fever and headaches, she is currently taking amoxillin as per the dentist. They told me she had an infection on one of her teeth, which is why they put her on the antibiotic. I am concerned she may have meningitis.

Hi..
Thanks for the query..

Fever and headache after a dental procedure when she already has infection in one of the tooth is due to infection only..

When the infection is severe it can enter the blood from the site of infection causing bacteriemia and septicemia and it can cause infection and the most common presentation is fever..

So as she is already been advised amoxicillin, probably the infection will subside and also fever..
Add Acetaminophen to reduce fever and pain..

In case if the symptoms does not get better in a week then you can consult an Emergency room and get her evaluated..

Hope this helps..

Regards..

Welcome to healthcare magic.

As you mentioned you have problem of tooth infection present that may lead to fever..
Start a antibiotics course..
If possible than start a treatment of that affected tooth ..
Painkiller can taken if needed..
Take x ray of affected tooth to know how much infection present..
Mention a intensity and duration of pain ..
Consult your dentist again for further diagnosis and treatment.
