Wisdom tooth pain and gum infections often share similar symptoms, such as swelling, jaw stiffness, and localized discomfort. While erupting wisdom teeth can cause temporary pressure, an infection—known as pericoronitis—requires immediate professional care to prevent the spread of bacteria. At All About Teeth, we provide emergency evaluations to diagnose the source of your pain and determine if an extraction or specialized cleaning is necessary to protect your oral health.
Quick Summary: Identifying the Source of Oral Pain
- Check the Location: Is the pain localized behind the last visible molar?
- Monitor for Fever: A systemic fever often indicates an active infection rather than simple tooth eruption.
- Observe the Gums: Look for a “flap” of tissue or redness at the back of the jaw.
- Assess Jaw Mobility: Difficulty opening your mouth is a sign of a serious wisdom tooth complication.
Understanding Wisdom Tooth Eruption vs. Infection
As wisdom teeth (third molars) attempt to emerge, they often lack sufficient space in the jaw. This can lead to “impaction,” where the tooth remains trapped or only partially emerges through the gum line.
Definition: Pericoronitis
Pericoronitis is a dental infection that occurs when gum tissue overlaps a partially erupted wisdom tooth. This “flap” of skin traps food particles and bacteria, making it nearly impossible to clean with regular brushing. If left untreated, the inflammation can spread to the cheeks, jaw, and neck.
Comparison: Symptoms of Eruption vs. Pericoronitis
| Symptom | Normal Wisdom Tooth Eruption | Infected Gum (Pericoronitis) |
| Pain Level | Mild pressure or dull aching. | Sharp, throbbing pain that radiates to the ear or neck. |
| Swelling | Slight tenderness in the immediate area. | Noticeable swelling of the gums, cheek, or jawline. |
| Taste/Odor | No change in taste. | Persistent foul taste or bad breath due to pus/bacteria. |
| Jaw Function | Normal movement. | Difficulty or pain when opening the mouth (Trismus). |
When Wisdom Tooth Issues Become an Emergency
While many wisdom tooth extractions are planned, certain symptoms indicate you need to call our Logan office for emergency dental care immediately:
- Difficulty Swallowing or Breathing: This indicates severe swelling that may be obstructing your airway.
- Visible Pus: If you see a discharge around the back molars, an abscess has likely formed.
- High Fever and Chills: Systemic symptoms suggest the infection is no longer localized to the tooth.
- Severe “Referred” Pain: When a wisdom tooth is impacted, it can cause intense headaches or earaches that do not respond to over-the-counter pain relief.
Using our advanced digital x-rays, Dr. Corey Hogge can determine the exact position of your wisdom teeth and whether a gum infection is present.
Frequently Asked Questions
Can a wisdom tooth infection go away with antibiotics?
Antibiotics can temporarily reduce the bacteria, but they do not solve the underlying problem. If the tooth is impacted or a gum flap remains, the infection will almost certainly return until the tooth is removed or the tissue is treated.
Why does my ear hurt when I have wisdom tooth pain?
The nerves in your jaw are closely connected to the nerves in your ear. When a wisdom tooth is impacted or infected, the pain “radiates” along these nerve paths, making it feel like you have an earache.
What is the “flap” of skin over my back tooth?
This is called an operculum. It is common during the eruption of wisdom teeth but is the primary cause of pericoronitis because it acts as a pocket that traps food and bacteria.
Is wisdom tooth removal a major surgery?
Most wisdom tooth removals are routine procedures. At All About Teeth, we prioritize patient comfort and “Cater to Cowards,” ensuring you are well-informed and relaxed throughout the process.
What happens if I ignore an infected wisdom tooth?
Untreated infections can lead to dental abscesses, permanent damage to the adjacent 12-year molars, and bone loss in the jaw. In rare cases, the infection can spread to the bloodstream.
Does insurance cover emergency wisdom tooth exams?
Most insurance plans cover diagnostic exams and x-rays. We process insurance in our office and offer financing options (O.A.C.) to ensure you can get out of pain immediately.
At All About Teeth, we specialize in making dental visits comfortable, even when dealing with painful wisdom tooth complications. If you are experiencing swelling or throbbing pain at the back of your jaw, don’t wait for the infection to spread. We serve families across Logan and Cache Valley with professional, compassionate care.
