What Are the Signs of Infection After Impacted Molar Extraction?

Normal healing

You would expect some discomfort, slight swelling & some bleeding in the first couple of days after extraction of impacted molars. Pain would usually subside after the second day. If you are experiencing the above symptoms then healing would be proceeding normally. However, if symptoms are getting worse.

Increased pain

Increasing pain after the 3rd/4th day or referred pain to the ear, jaw or neck is a key indicator that something may be wrong. This could be due to infection or Dry Socket (loss of clot leaving the bone exposed). These are related so it is best to have a dentist look at the area.

Swelling and temperature

Swelling should subside after 48-72hours. If your cheek is still increasing in size, feels firm or is warm & red then infection is likely. A temperature of over 100.4F (38C) along with shivering or feeling generally tired indicates your body is fighting off bacteria.

Bad taste/smell

A persistent bad taste in your mouth, bad smell from your mouth or pus coming from the socket is a clear indicator. Pus may be yellow or white as well as may come from the gumline or surface of the wound.

Difficulty opening mouth, swallowing and breathing

Trismus (difficulty opening your mouth) can occur after surgery however increasing stiffness with pain should be addressed. Difficulty swallowing or breathing is an emergency. You should seek immediate help from an emergency room as infections in the neck can develop rapidly.

Modern Dentistry

Dentists will now use 3D imaging to look at the surgical site. Many surgeons will use platelet rich fibrin (from your own blood) to aid healing in the socket. Antbiotics are often used more specifically. Often irrigation & drainage is performed.

Prevention

Following the aftercare advice is very important. Try to avoid smoking, using a straw or forceful rinsing in the first few days. Keep your head raised, eat soft foods as well as start gently rinsing with salt water after 24 hours.

If you experience any of the above signs contact your dentist or oral surgeon on the same day. Usually treatment is straightforward if treated early.
