Toothache: Symptoms, Causes, and When to Seek Medical Care
A toothache is pain or discomfort in or around a tooth, gum, or jaw. It may feel sharp, throbbing, dull, constant, or triggered by chewing, temperature, sweets, or pressure.
Tooth pain can come from the tooth itself, the gums, the jaw, the sinuses, or nearby nerves. Some toothaches are mild and temporary, but others may signal infection, dental injury, abscess, or another condition that needs prompt dental or medical evaluation.
What is a toothache?
A toothache is pain involving the tooth, surrounding gum tissue, jaw, or nearby structures. It may affect one tooth, several teeth, or a wider area of the face or jaw.
Dental problems are a common cause, but pain near the teeth can sometimes come from sinus pressure, jaw/TMJ problems, ear pain, nerve irritation, or, rarely, more serious conditions.
Common causes
Common causes of toothache may include:
Tooth decay or cavity
Dental abscess
Gum disease
Cracked or broken tooth
Lost filling or crown
Tooth grinding or clenching
Tooth sensitivity
Impacted wisdom tooth
Recent dental procedure
Sinus infection or sinus pressure
Jaw/TMJ irritation
Dental trauma or injury
Food trapped between teeth
Infection around the gum or tooth root
Common symptoms
Toothache symptoms may include:
Tooth pain
Gum pain or swelling
Jaw pain
Throbbing discomfort
Pain with chewing
Sensitivity to hot, cold, or sweets
Bad taste in the mouth
Bad breath
Facial swelling
Swollen lymph nodes
Fever
Headache
Ear pain
Pain that wakes you from sleep
Drainage or pus near the gum
A tooth abscess may cause severe tooth pain, swelling, fever, bad taste, pus, or pain that spreads to the jaw, ear, or neck.
Risk factors
Toothache may be more likely in people who have:
Cavities or history of dental decay
Gum disease
Poor access to dental care
Dry mouth
Smoking or tobacco use
Diabetes
Weakened immune system
Frequent sugary drinks or snacks
Acid reflux or frequent vomiting
Teeth grinding or clenching
Prior dental work
Cracked teeth or dental injury
Poorly fitting dental appliances
Wisdom teeth problems
When to seek medical care
Schedule dental or medical evaluation if you have:
Tooth pain lasting more than 1-2 days
Pain that is worsening
Gum swelling
Facial swelling
Pain with chewing
Sensitivity that does not improve
Broken, cracked, or injured tooth
Lost filling or crown
Bad taste or drainage from the gum
Fever
Swollen lymph nodes
Trouble opening your mouth fully
Tooth pain with sinus symptoms that persists
Diabetes or weakened immune system
Recurrent tooth or gum infections
A dentist is usually the best professional to evaluate tooth-related pain because dental imaging or dental procedures may be needed.
When to seek urgent or emergency care
Seek urgent or emergency care for:
Facial, jaw, or neck swelling that is worsening
Swelling under the jaw or tongue
Trouble breathing
Trouble swallowing
Drooling or inability to swallow saliva
Fever with facial swelling
Severe pain with swelling
Confusion or severe weakness
Rapidly spreading redness or warmth of the face or neck
Trouble opening the mouth
Eye swelling or vision changes
Severe headache with facial swelling
Signs of severe allergic reaction
Chest pain or shortness of breath
Symptoms that are rapidly worsening
Dental infections can sometimes spread and become serious. Breathing difficulty, swallowing difficulty, neck swelling, or rapidly worsening facial swelling should not wait.
Can telehealth help?
Telehealth may help review symptoms, timing, risk factors, medication safety, and whether urgent dental care, urgent care, emergency care, or in-person evaluation may be needed.
However, toothaches often require dental evaluation. Telehealth cannot replace dental X-rays, dental procedures, drainage of an abscess, tooth repair, extraction, or other dental treatment when needed.
Prevention and follow-up
General prevention and follow-up considerations include:
Routine dental checkups
Brushing and flossing consistently
Addressing cavities early
Managing dry mouth concerns
Limiting frequent sugary drinks and snacks
Wearing a night guard if recommended for grinding
Following up after dental injury
Seeking care early for gum swelling or dental pain
Managing diabetes and immune-related risk factors
Avoiding delay when infection symptoms are present
Final thought
A toothache can be caused by cavities, gum disease, cracked teeth, sinus pressure, jaw problems, or dental infection. Pain with swelling, fever, drainage, trouble swallowing, trouble breathing, or rapidly worsening symptoms should be evaluated promptly.
