Tooth pain can range from a mild twinge when you drink something cold to a constant ache that keeps you awake at night. Whatever the severity, a toothache is often your body’s way of signalling that something needs attention.
Understanding the common reasons for toothache can help you decide when to monitor your symptoms and when to seek professional dental care. At Dental At Forest Hill, we provide friendly, thorough assessments to identify the cause of dental pain and recommend treatment suited to your needs.
Tooth pain is your body’s way of saying something needs attention. Discover common causes of toothache and when to see a dentist.
Why does toothache happen?
Toothache usually occurs when the sensitive inner layers of a tooth become irritated or inflamed. This may happen because of decay, damage, infection, gum problems or pressure from nearby teeth.
Pain can feel different depending on the cause. You may experience:
- A sharp pain when biting
- Sensitivity to hot, cold or sweet foods
- A dull, persistent ache
- Throbbing pain
- Pain that spreads to the jaw, ear or face
- Tender or swollen gums
Because several dental conditions can cause similar symptoms, an examination is the safest way to determine what is happening.
Common reasons for toothache
1. Tooth decay
Tooth decay is one of the most common causes of dental pain. It develops when bacteria in plaque produce acids that gradually weaken the tooth’s outer surface.
Early decay may cause no symptoms. As it progresses deeper into the tooth, you may notice:
- Sensitivity to cold, heat or sweet foods
- Food becoming trapped in one area
- A visible dark spot or hole
- Pain when chewing
A small cavity may be treated with a filling. If decay reaches the tooth’s nerve, more extensive treatment may be needed.
2. A cracked or damaged tooth
A cracked tooth can cause sudden, sharp pain, particularly when biting or releasing your bite. Cracks may result from:
- Biting hard foods
- Teeth grinding or clenching
- An injury or accident
- Large, older fillings
- General wear over time
Some cracks are difficult to see, even with a mirror. A dentist may need to assess your bite and take dental X-rays to investigate the problem.
3. Dental infection or abscess
A dental abscess is a collection of infected fluid that can develop inside a tooth or in the surrounding gum. It may cause:
- Severe, throbbing tooth pain
- Facial or jaw swelling
- A bad taste in the mouth
- Fever or feeling unwell
- Pain when biting
- Sensitivity to hot and cold
A dental abscess requires prompt professional care. It will not reliably resolve on its own, even if it begins draining and the pain temporarily improves.
Seek urgent medical attention if tooth pain is accompanied by difficulty breathing, swallowing or opening your mouth, or swelling that is spreading.
4. Gum disease
Gum disease begins when plaque builds up around the teeth and irritates the gums. Early gum disease may cause bleeding, redness or swelling. More advanced disease can affect the tissues and bone supporting the teeth.
Symptoms may include:
- Bleeding when brushing or flossing
- Sore or swollen gums
- Persistent bad breath
- Receding gums
- Loose or sensitive teeth
Gum-related discomfort is sometimes mistaken for tooth pain. Regular dental examinations and professional cleaning can help identify and manage gum disease.
5. Tooth sensitivity
Sensitive teeth may hurt briefly when exposed to cold drinks, hot foods, sweet items or cold air. Sensitivity can occur when the protective enamel becomes worn or when the gums recede and expose the tooth root.
Possible causes include:
- Brushing too forcefully
- Tooth grinding
- Acidic foods and drinks
- Gum recession
- Tooth whitening products
- Tooth decay or a crack
Occasional sensitivity may improve with a desensitising toothpaste, but new, worsening or localised sensitivity should be checked by a dentist.
6. Loose or damaged dental fillings
A filling can become worn, cracked or loose over time. When this happens, the tooth may become sensitive or painful, particularly when chewing.
A damaged filling can also allow bacteria to enter the tooth again. Your dentist may recommend repairing or replacing the filling, depending on the extent of the damage.
7. Teeth grinding and jaw clenching
Grinding or clenching, known as bruxism, can place excessive pressure on the teeth and jaw. It may occur during sleep or when you are stressed or concentrating.
Signs may include:
- Aching teeth in the morning
- Headaches around the temples
- Jaw soreness or clicking
- Flattened, chipped or worn teeth
- Increased tooth sensitivity
Treatment may include a custom night guard, managing contributing factors and repairing damage to the teeth.
8. Wisdom teeth
Wisdom teeth can cause pain when they do not have enough room to grow properly. A partially erupted wisdom tooth may trap food and bacteria beneath the gum, leading to inflammation or infection.
Wisdom tooth symptoms can include:
- Pain at the back of the mouth
- Swollen or tender gums
- Jaw stiffness
- Bad breath or an unpleasant taste
- Difficulty opening the mouth
A dental examination and X-ray can show the position of the wisdom tooth and help determine whether monitoring, cleaning or treatment is appropriate.
9. Food trapped between teeth
Food lodged between teeth can put pressure on the gums and create localised soreness. It may also encourage plaque and bacteria to build up.
Carefully flossing or using an interdental brush may help remove the food. Avoid using sharp objects, as these can injure your gums or damage the tooth. If the discomfort continues, arrange a dental check-up.
10. Sinus pressure
The upper teeth sit close to the sinus cavities. Congestion or a sinus infection can sometimes create pressure that feels like toothache, particularly in several upper teeth at once.
Sinus-related discomfort may occur alongside:
- A blocked or runny nose
- Facial pressure
- Headache
- Pain that changes when bending forward
Even when sinus pressure is suspected, dental causes should be ruled out if the pain is severe, focused on one tooth or does not improve.
When should you see a dentist for tooth pain?
Arrange a dental appointment if your toothache:
- Lasts longer than one or two days
- Is getting worse
- Returns repeatedly
- Makes eating or sleeping difficult
- Comes with swelling, bleeding or a bad taste
- Is associated with a broken or knocked-out tooth
- Causes sensitivity in one specific tooth
Early treatment may help prevent a minor problem from becoming more complex and uncomfortable.
What can you do while waiting for your appointment?
These steps may provide temporary relief:
- Rinse gently with warm water.
- Floss carefully to remove trapped food.
- Use a cold compress on the outside of the cheek if there is swelling.
- Eat softer foods and chew on the opposite side.
- Avoid very hot, cold or sugary foods.
- Take over-the-counter pain relief only as directed on the label or by a healthcare professional.
Do not place aspirin directly on the tooth or gum, as it can burn the soft tissues. Pain relief should not replace a dental examination.
How is the cause of toothache diagnosed?
At Dental At Forest Hill, your dentist may:
- Ask when the pain started and what triggers it.
- Examine the teeth, gums and surrounding tissues.
- Check how the teeth respond to temperature or pressure.
- Assess your bite and jaw.
- Take an X-ray when needed.
The recommended treatment depends on the cause. It may involve preventive care, a filling, treatment for gum disease, a protective dental restoration or other appropriate care.
Preventing toothache
Although not every dental problem can be avoided, good daily habits can reduce your risk:
- Brush twice daily with fluoride toothpaste.
- Clean between your teeth each day.
- Limit frequent sugary snacks and drinks.
- Drink water regularly.
- Wear a mouthguard during contact sports.
- Avoid using your teeth to open packages.
- Attend routine dental check-ups.
- Seek advice about grinding or persistent sensitivity.
Frequently Asked Questions - FAQ's
Q: What is the most common reason for toothache?
A: Tooth decay is one of the most common reasons for toothache. As decay moves through the tooth, it can irritate the sensitive inner tissue and cause pain or sensitivity. However, toothache may also result from a crack, infection, gum disease, grinding or trapped food, so an examination is important.
Q: How do I know if my toothache is serious?
A: Toothache may be serious if it is severe, persistent or accompanied by swelling, fever, a bad taste, difficulty opening your mouth, or pain when biting. Swelling that affects breathing or swallowing requires urgent medical attention. Contact a dentist promptly rather than waiting for symptoms to worsen.
Q: Can a toothache go away on its own?
A: A toothache may temporarily improve, but this does not necessarily mean the underlying problem has healed. Dental decay, cracks and infections generally require professional assessment and treatment. If pain disappears after being severe, the tooth may still need care, particularly if the nerve has been affected.
Q: What can I take for toothache?
A: Over-the-counter pain relief may help temporarily when used according to the packet directions and your healthcare professional’s advice. Do not place aspirin directly on the tooth or gum. Pain medication does not treat the cause, so arrange a dental appointment if the pain continues or returns.
Q: How long should I wait before seeing a dentist for tooth pain?
A: You should contact a dentist if tooth pain lasts longer than one or two days, becomes worse or keeps returning. Seek prompt care for swelling, fever, a broken tooth, severe pain or difficulty eating. Early assessment can often make treatment simpler and help prevent further damage.
Q: Can a dentist fix a toothache in one appointment?
A: Sometimes a toothache can be treated in one appointment, such as when it is caused by a small cavity or a damaged filling. More complex problems, including infection or extensive tooth damage, may require several stages of care. Your dentist will explain the options after examining you.
