Dental abscess and jaw infection
Dental infection usually requires treatment of its source. Antibiotics alone do not replace drainage, dental treatment or indicated surgery.
Possible symptoms
- Throbbing toothache or pain on biting.
- Swelling of the gum, cheek or under the jaw.
- Bad taste, discharge or difficulty opening the mouth.
- Fever, fatigue or swollen glands.
Treating the source
Depending on the cause, treatment may be endodontic, periodontal or surgical and may include drainage or extraction. X-rays help identify the source. Antibiotics are reserved for situations where they are indicated.
Avoid
- Using leftover antibiotics or somebody else’s prescription.
- Stopping or extending prescribed treatment yourself.
- Repeated anti-inflammatory medication without advice.
- Waiting while swelling spreads or general health deteriorates.
Emergency
Fever with facial swelling, breathing or swallowing difficulty, altered voice, floor-of-mouth swelling, severe trismus or rapid deterioration requires emergency care.
