Dental emergencies can happen at any time — from an unexpected sports injury to a nagging toothache that suddenly becomes unbearable. While some incidents are unavoidable, many common dental emergencies can be prevented with the right care and awareness.
At Brisbane Emergency Dentist, we help hundreds of patients every year who experience dental trauma or sudden oral pain. In many cases, a few small preventive habits could have avoided the issue altogether.
In this blog, we’ll cover the top seven causes of dental emergencies and share expert tips to help you prevent them.
1. Sports Injuries
Brisbane’s love for sport means dental trauma is a frequent occurrence. Contact sports such as rugby, football, hockey, and basketball carry a high risk of knocks to the mouth. Even non-contact activities like cycling or skateboarding can lead to chipped, broken, or knocked-out teeth.
Why it happens:
Direct impact to the jaw or mouth during sports can crack teeth, damage gums, or dislodge dental restorations such as crowns and veneers.
How to prevent it:
- Always wear a custom-fitted mouthguard during sports or training.
- Avoid cheap, over-the-counter guards that provide poor protection.
- Replace worn or ill-fitting mouthguards regularly.
Emergency dentist tip:
If a tooth gets knocked out during sport, place it in milk or saline and call an emergency dentist immediately. Acting quickly can save your tooth.
2. Teeth Grinding (Bruxism)
Many people grind or clench their teeth without realising — often during sleep or moments of stress. Over time, this constant pressure wears down enamel and weakens teeth, increasing the risk of fractures.
Why it happens:
Bruxism is often linked to anxiety, poor sleep, or an abnormal bite. Left untreated, it can cause headaches, jaw pain, and broken fillings.
How to prevent it:
- Ask your dentist about a night guard to protect your teeth while sleeping.
- Practise relaxation techniques to manage stress.
- Avoid chewing on pens, ice, or hard objects.
Emergency dentist tip:
If you wake up with jaw pain or chipped teeth, book an appointment promptly. Your dentist can repair the damage and help prevent further wear.
3. Poor Oral Hygiene
Neglecting your oral hygiene can slowly lead to major problems — cavities, gum infections, and tooth loss. These conditions are some of the most common causes of dental pain and emergencies.
Why it happens:
Plaque and bacteria accumulate when brushing and flossing habits are inconsistent, causing decay and gum inflammation.
How to prevent it:
- Brush twice daily with a fluoride toothpaste.
- Floss once a day to clean between teeth.
- Visit your dentist every six months for a professional clean and check-up.
Emergency dentist tip:
Treat small cavities early. Waiting too long often results in infections or abscesses that require urgent attention.
4. Biting Down on Hard Foods
Crunching on ice, nuts, hard sweets, or unpopped popcorn kernels can unexpectedly crack or chip a tooth. Even biting into hard bread crusts or bones can cause trauma, especially if a tooth is already weakened.
Why it happens:
Excessive force from chewing hard substances can fracture enamel or dislodge fillings.
How to prevent it:
- Avoid chewing ice or using your teeth to open packaging.
- Cut hard foods into smaller pieces before eating.
- Strengthen your teeth with a balanced diet rich in calcium and vitamins.
Emergency dentist tip:
If you chip or crack a tooth, save any broken pieces and call your dentist immediately. Small fractures can often be repaired quickly if treated early.
5. Untreated Tooth Decay
Tooth decay doesn’t cause noticeable pain until it’s advanced — but when it does, it can turn into a dental emergency overnight. Decay weakens the structure of the tooth and can lead to infection if bacteria reach the nerve.
Why it happens:
Skipping dental check-ups allows cavities to grow silently. Poor diet and sugary drinks accelerate the problem.
How to prevent it:
- Schedule regular check-ups and fillings before decay spreads.
- Limit sugary snacks and acidic drinks.
- Drink plenty of water to rinse away food particles.
Emergency dentist tip:
If you experience constant or throbbing tooth pain, it may be a sign of infection. Don’t ignore it — contact an emergency dentist straight away.
6. Accidents and Falls
A simple trip, fall, or car accident can easily result in dental trauma. Injuries may include loosened teeth, jaw pain, or broken dental restorations.
Why it happens:
Physical impact or sudden force can damage teeth and surrounding tissues.
How to prevent it:
- Use handrails and wear appropriate footwear to avoid slips.
- Always wear a seatbelt when driving.
- Keep living areas well-lit and free from tripping hazards.
Emergency dentist tip:
If you suffer a dental injury from a fall, even without visible damage, see a dentist promptly. Hairline cracks and internal injuries can worsen if untreated.
7. Gum Disease
Gum disease (periodontitis) is a slow-developing condition that can eventually cause sudden pain, bleeding, and even tooth loss. It’s one of the most common reasons for emergency dental visits among adults.
Why it happens:
Plaque build-up along the gum line leads to inflammation and infection, which damages the tissues supporting your teeth.
How to prevent it:
- Maintain excellent oral hygiene and attend regular cleanings.
- Avoid smoking, as it increases the risk of gum disease.
- Eat a nutrient-rich diet to strengthen your gums.
Emergency dentist tip:
If your gums bleed frequently or you notice swelling and bad breath, book a dental visit immediately. Early intervention prevents serious complications.
When to See an Emergency Dentist
If you experience:
- Persistent pain or swelling.
- A knocked-out, cracked, or loose tooth.
- Bleeding that doesn’t stop.
- Facial swelling or fever.
You should contact an emergency dentist straight away. Delaying treatment can make the situation worse and may result in permanent tooth damage.
