Trigeminal Neuralgia or Toothache? Understanding Facial Pain
Pain in the cheek, jaw, teeth or gums can be difficult to interpret. A toothache may feel as though it spreads across the face, while trigeminal neuralgia can sometimes feel as though it is coming from a particular tooth.
Symptoms alone cannot always identify the cause. Understanding the typical patterns can help you describe your pain, but an appropriate medical or dental assessment is important before drawing conclusions.
What does trigeminal neuralgia feel like?
Trigeminal neuralgia commonly causes sudden, intense facial pain. It is often described as sharp, stabbing, shooting or similar to an electric shock.
The pain usually affects one side of the face and may occur in the cheek, jaw, teeth, gums, lips, forehead or around the eye. An attack may last for several seconds or longer and may happen repeatedly throughout the day.
Talking, chewing, swallowing, brushing your teeth or lightly touching your face may trigger an attack. Some people also experience tingling, numbness or a persistent aching or burning sensation between attacks.
How can dental pain feel different?
Dental pain may be associated with tooth decay, infection, a cracked tooth, gum disease or another oral health concern. Depending on the cause, it may feel aching, throbbing, sharp or sensitive to pressure and temperature.
Possible signs of a dental problem can include:
- Pain that appears centred around a particular tooth or gum
- Pain when biting or placing pressure on a tooth
- Swelling, redness or tenderness around the gum
- A damaged, loose or visibly decayed tooth
- An unpleasant taste or discharge in the mouth
- Fever or facial swelling associated with dental pain
These features do not confirm a diagnosis. A dentist may need to examine your teeth and gums and take dental imaging to identify or rule out a dental cause.
Could it be a jaw or sinus problem?
Temporomandibular joint—or TMJ—conditions can cause pain around the jaw, temple or ear. Symptoms may become more noticeable with jaw movement and can occur alongside clicking, stiffness or difficulty opening the mouth.
Sinus conditions may cause facial pressure or discomfort, often with nasal congestion, discharge or other respiratory symptoms. Migraine and other headache conditions can also cause pain or sensitivity involving the face.
Because several conditions can produce overlapping symptoms, self-diagnosis may delay appropriate care.
Why professional assessment matters
A doctor will usually ask where the pain occurs, how it feels, how long each episode lasts and what appears to trigger it. They may also examine your face and nervous system and review your dental and medical history.
Depending on your presentation, your doctor may recommend a dental assessment, MRI, CT scan or referral to a neurologist or another healthcare professional. The purpose is to investigate trigeminal neuralgia and exclude other possible causes of facial pain.
What information should you record?
Before your appointment, make a note of:
- The exact location and side of your facial pain
- Whether it feels electric, stabbing, burning, aching or throbbing
- How suddenly it begins and how long it lasts
- Activities or sensations that trigger it
- Any numbness, tingling, weakness or facial twitching
- Recent dental treatment or dental symptoms
- Current medicines and previous treatment approaches
This information can help your doctor or dentist recognise the pattern and decide what further assessment may be required.
When does facial pain require urgent attention?
Seek urgent dental or medical care if facial pain occurs with significant swelling, fever, difficulty swallowing, difficulty breathing or signs of a spreading infection.
Call Triple Zero on 000 for facial drooping, difficulty speaking, sudden weakness or numbness in an arm or leg, confusion, sudden vision changes or an unusually severe and sudden headache.
Arrange an online consultation
Adults experiencing diagnosed or persistent facial nerve pain can begin with Herbly’s online trigeminal neuralgia consultation process.
A Herbly doctor can review your symptoms, medical history, current medicines and previous investigations. Telehealth may not be suitable for every presentation, and your doctor may recommend an in-person examination, dental assessment, imaging or specialist care.
