Toothache
Informed by recognized medical guidance
Overview
A toothache is pain in or around a tooth. It can range from mild discomfort to severe, sharp pain. The most common cause is a cavity (a hole in the tooth), but other issues with the gums, jaw, or sinuses can also trigger it.
Key facts
- Toothache is usually a sign that something is wrong with a tooth or its surrounding area.
- Most toothaches are caused by tooth decay (cavities) or gum disease.
- Prompt treatment can prevent the problem from getting worse and relieve pain.
Yes, toothache is very common. Most people will experience at least one toothache during their lifetime.
Toothache can affect anyone, but it is more common in children and young adults. People with poor oral hygiene, a diet high in sugar, or who smoke are at higher risk.
Symptoms
- Severe tooth pain along with swelling in the face, neck, or eye that makes it hard to breathe or swallow
- Fever over 101°F (38.3°C) with tooth pain
- Tooth pain after a serious injury to the face or jaw
- Bleeding from the mouth that won't stop
- ⚠Tooth pain that lasts more than 1-2 days
- ⚠Pain so bad you can't eat, sleep, or work
- ⚠Swelling around the tooth that is getting worse
- ⚠Signs of infection like pus, fever, or foul taste in the mouth
Common symptoms
- Pain in or around a tooth that may be constant or come and go
- Sharp or throbbing pain, especially when biting or chewing
- Sensitivity to hot, cold, or sweet foods and drinks
- Swelling around the tooth or in the gums
- Bad taste in the mouth or bad breath
Symptoms in children
- Complaining of a sore tooth
- Trouble eating or sleeping
- Pulling at the cheek or ear
- Irritability or crying more than usual
Symptoms in older adults
- Dull, nagging pain that may be mistaken for jaw pain
- Pain from underlying gum disease or worn-down teeth
- Sensitivity to temperature changes
- Loose teeth or receding gums
Causes
Main causes
- Tooth decay (cavity) – a hole in the tooth caused by plaque damaging the enamel
- Gum disease (gingivitis or periodontitis) – infection of the gums that can reach the tooth root
- Abscess – a pocket of pus caused by a bacterial infection inside the tooth or gum
- Cracked or fractured tooth – can expose the sensitive inner layers
- Sinus infection or sinusitis – the upper back teeth can hurt when the sinuses are inflamed (ENT link)
- Teeth grinding (bruxism) – can wear down teeth and cause pain
Risk factors
- Poor oral hygiene (not brushing or flossing regularly)
- Eating a lot of sugary foods and drinks
- Smoking or using tobacco products
- Having a dry mouth (less saliva)
- Conditions like diabetes that can affect gum health
- Age – cavities are more common in children and teens
When to see a doctor
See a doctor urgently if:
- Pain that is severe and doesn't go away with over-the-counter pain medicine
- Swelling in your face or jaw that is getting worse
- Fever or signs of infection (pus, chills, bad taste)
- Difficulty opening your mouth, breathing, or swallowing
Book a routine appointment if:
- Mild tooth pain that lasts more than a day or two
- Sensitivity to hot or cold that doesn't improve
- A broken or chipped tooth, even if it doesn't hurt
- Bleeding gums when you brush or floss
Diagnosis
A doctor or dentist will ask about your symptoms, examine your mouth, and look for signs of decay, infection, or injury.
Tests that may be done
- Visual exam of your teeth and gums
- Tapping on the tooth to check for tenderness
- X-rays to see cavities, abscesses, or bone loss
- Sometimes a cold or hot test to see which tooth is sensitive
What to expect at your appointment
The exam is usually quick and painless. If X-rays are needed, you may wear a heavy apron to protect the rest of your body. The dentist will explain what they find and recommend next steps.
Treatment
Treatment for toothache depends on the cause. The goal is to relieve pain, stop infection, and save the tooth if possible. Many toothaches can be treated by a dentist in the office.
Self-care at home
- Rinse your mouth with warm salt water (half a teaspoon of salt in a cup of water) to reduce inflammation
- Apply a cold compress (ice pack wrapped in a cloth) to the outside of your cheek for 15 minutes at a time
- Avoid very hot, cold, or sweet foods and drinks until you see a dentist
- Take over-the-counter pain medicine like ibuprofen or acetaminophen – follow the label instructions and talk to your doctor if you have any health conditions
- Sleep with your head elevated to help reduce swelling
Medical treatments
Dentists can treat a cavity by removing the decay and placing a filling. If the decay reaches the inner pulp, a root canal may be needed to remove infected tissue and seal the tooth. For infections, an antibiotic may be prescribed. Gum disease can be treated with deep cleaning (scaling and root planing).
When is surgery considered?
In some cases, if the tooth is badly damaged or infected, the tooth may need to be pulled (extracted). This is usually a last resort. Surgery may also be needed to drain an abscess.
Living with this condition
Until you see a dentist, manage pain with self-care. Avoid chewing on the painful side. Eat soft foods that aren't too hot or cold. Keep your mouth clean by gently brushing and flossing around the sore area.
Lifestyle tips
- Brush your teeth twice a day with fluoride toothpaste
- Floss once a day to remove food and plaque between teeth
- Cut down on sugary snacks and drinks
- Don't smoke or use tobacco
- Stay hydrated – dry mouth can make tooth problems worse
Diet and exercise
Eat a balanced diet with plenty of fruits, vegetables, and calcium-rich foods (like milk and yogurt). Limit sugary treats. Exercise doesn't directly affect toothache, but staying healthy supports your immune system.
Mental health and emotional wellbeing
Chronic tooth pain can be frustrating and affect your mood, sleep, and ability to concentrate. It's normal to feel anxious or stressed. Talk to your dentist about pain management and don't ignore the emotional side of ongoing discomfort.
Prevention
Most toothaches can be prevented with good oral hygiene and regular dental check-ups. Brushing, flossing, and avoiding too much sugar go a long way. Wearing a mouthguard if you grind your teeth or play contact sports also helps.
Vaccines
No vaccines prevent toothache, but staying up to date on vaccines (like tetanus) can protect your overall health.
Screening programmes
Routine dental check-ups (usually every 6 to 12 months) can catch cavities and gum disease early before they cause pain. Your dentist may also take X-rays periodically to screen for hidden problems.
Complications
If left untreated
- The infection can spread to the jaw bone, face, or bloodstream (a serious condition called sepsis)
- A tooth abscess can burst, causing worse pain and more serious infection
- The tooth may need to be extracted if damage becomes too severe
- Gum disease can lead to tooth loss and bone damage
Long-term outlook
With proper treatment, most toothaches can be resolved and the tooth can be saved. Even if a tooth needs to be removed, there are options like bridges or implants to replace it. The key is to see a dentist as soon as possible – the earlier the better. Your smile and your health are worth it.
