Common causes of sudden toothache
There are several reasons for sudden toothache, ranging from minor sensitivity to serious infections. Understanding the sudden toothache causes can help you determine the best course of action:
1. Tooth decay and cavities
One of the most common reasons for sudden toothache is untreated cavities. Decay can reach the nerve, causing a sudden intense toothache or sudden severe toothache that worsens with hot, cold, or sweet foods.
2. Tooth fractures or cracks
A sudden toothache after eating could result from a cracked tooth. Hard foods or accidental biting on something solid can cause micro-fractures that expose the nerve, leading to sensitivity and pain. Unlike a normal toothache that develops due to decay, a fractured tooth causes immediate sharp pain, especially when biting or chewing.
3. Sinus infections
Many people don’t realize that sinus infections can cause toothache all of a sudden, especially in the upper molars. If you have congestion, facial pressure, and a sudden toothache, your sinuses may be to blame.
4. Bruxism (teeth grinding)
Grinding your teeth at night can lead to a sudden toothache while sleeping. Over time, bruxism wears down enamel, causing sensitivity and discomfort.
5. Food stuck between teeth
Sometimes, a sudden toothache pain is simply caused by food debris wedged between your teeth. Flossing and rinsing can often relieve the discomfort. This can cause acute, localized pain that is quickly relieved after flossing, unlike a typical toothache from decay, which is persistent rather than immediate.
6. Temperature sensitivity
Enamel erosion or receding gums can cause a sudden toothache at night or after consuming hot or cold drinks. This type of pain is usually sharp and short-lived.

Is a sudden toothache dangerous?
A sudden toothache can range from mild discomfort to a severe dental emergency. While some cases may resolve with home remedies, others can indicate serious underlying issues that require urgent dental care. Here’s when a sudden severe toothache becomes dangerous:
- Intense, throbbing pain
If your sudden painful toothache is persistent and worsening, it may indicate an infection, such as tooth abscess, which requires immediate treatment.
- Swelling in the face or jaw
A sudden toothache and jaw pain accompanied by swelling can signal an infection that is spreading, potentially leading to serious health risks if left untreated.
- Fever & pus around the tooth
Signs of infection, including fever, pus discharge, or a bad taste in the mouth, suggest a bacterial issue that could become life-threatening if the infection spreads to other parts of the body.
- Sudden toothache at night that disrupts sleep
Pain that intensifies when lying down could indicate deep decay, nerve damage, or an abscess, requiring immediate care.
- Difficulty breathing or swallowing
A dental infection can sometimes spread to the throat, causing breathing difficulties, which can be a medical emergency.

Quick remedies for sudden toothache while traveling
If you’re experiencing a sudden toothache in Hanoi and can’t visit a dentist immediately, try these sudden toothache home remedies:
- Saltwater rinse: Dissolve half a teaspoon of salt in a glass of warm water and swish it around your mouth for 30 seconds before spitting it out. This natural antiseptic solution helps reduce inflammation, cleanse the affected area, and alleviate discomfort caused by a sudden painful toothache.
- Cold compress: Wrap an ice pack or a bag of frozen peas in a cloth and apply it to the outside of your cheek near the affected tooth for 15–20 minutes. This method helps numb the pain, reduce swelling, and minimize discomfort associated with sudden intense toothache and jaw pain.
- Clove oil: Soak a cotton ball in clove oil and gently press it against the aching tooth for a few minutes. Clove oil contains eugenol, a natural anesthetic and antibacterial agent that can provide temporary relief for sudden severe toothache and fight off infections. If clove oil is too strong, dilute it with a few drops of carrier oil like coconut or olive oil.
- Over-the-counter pain relievers: Taking ibuprofen, acetaminophen, or aspirin as directed can help reduce pain and inflammation associated with sudden onset toothache. Be sure to follow the recommended dosage and avoid placing aspirin directly on the tooth or gums, as this may cause irritation.
- Garlic paste: Crush a garlic clove to form a paste and apply it directly to the painful tooth. Garlic has natural antibacterial and analgesic properties that can help fight infections, making it an effective home remedy for sudden toothache after eating or sleeping. Adding a pinch of salt to the paste may further enhance its pain-relieving effects.
