Tooth pain that intensifies at night is a common complaint and can be deeply distressing, especially when it disrupts sleep. While some may experience mild discomfort, others may report extreme tooth pain that prevents them from sleeping altogether. This increase in intensity is often related to changes in blood flow and head positioning when lying down, making the tooth more sensitive and pressure more noticeable. Additionally, the absence of daytime distractions means the brain focuses more acutely on pain signals. If the discomfort becomes unbearable or persistent, it’s best to contact an emergency dentist for immediate evaluation and relief.
What are the most common causes of extreme tooth pain?
Severe tooth pain is usually a signal that something within the tooth or surrounding gum tissue requires immediate attention. Common clinical causes include:
- Advanced tooth decay exposing the inner nerve
- Tooth abscesses or localised infections
- Cracked or fractured teeth
- Gum infections such as periodontitis
- Erupting or impacted wisdom teeth
- Pressure from grinding or clenching teeth (bruxism)
It is important to understand that the severity of pain does not always correlate with the severity of the underlying issue. Only a thorough dental examination can determine the true cause.
Why does lying down make the pain worse?
When a person lies flat, more blood flows to the head. This can increase the pressure around inflamed areas in the mouth, including nerves within or around the tooth. That heightened pressure may amplify sensations of pain. Furthermore, while asleep or resting, the jaw is less active, leading to stagnation of inflammation or fluid buildup.
Other contributing factors may include:
- Decreased distractions leading to greater awareness of pain
- Heightened nerve sensitivity during quiet periods
- Clenching during sleep without realising it
What signs indicate that my tooth pain needs urgent dental attention?
Although many types of dental discomfort are manageable, certain symptoms suggest the need for prompt assessment. You should contact a dental clinic promptly if you notice:
- Swelling in the face, cheek or jaw
- Persistent throbbing pain
- Fever or general feelings of illness
- A foul taste or odour in the mouth
- Difficulty opening the mouth or swallowing
- Pain that prevents you from functioning normally or sleeping
Left untreated, infections and underlying causes may progress, potentially affecting surrounding tissues or even leading to systemic health issues.
What can I do until I can see a dentist?
While waiting for your dental appointment with your nearest dentist, it’s important to manage symptoms without interfering with the diagnosis or worsening the condition. General non-clinical management includes:
- Keeping your head elevated while resting
- Applying a cold compress externally on the affected side of the face
- Rinsing gently with warm, salty water (without swallowing)
- Avoiding chewing on the painful side
- Using a soft-bristled toothbrush and maintaining oral hygiene
Pain-relieving medications may be used as directed by a pharmacist or medical practitioner. It is essential to only take medication in line with medical advice and not use it as a substitute for treatment.

Important FAQ’s
Q1: Can I ignore severe tooth pain if it goes away after a few hours?
No. Even if the pain temporarily subsides, it may indicate an underlying issue that could worsen over time. Delaying assessment might result in more complex treatment needs.
Q2: Why does toothache seem worse at night compared to the day?
Night-time exacerbation of tooth pain is common due to increased blood flow when lying down and fewer distractions to divert attention from the discomfort.
Q3: Is it safe to take over-the-counter painkillers for dental pain?
Only take painkillers as advised by a pharmacist or health professional. They can provide short-term relief but do not address the cause of the pain.
Q4: What should I do if my face starts swelling with tooth pain?
Facial swelling may indicate a spreading infection and should be addressed by a dentist or emergency department immediately.
Q5: Can a cracked tooth cause pain even if it’s not visibly damaged?
Yes. Microfractures in teeth can cause sharp or intermittent pain, especially when chewing or exposed to temperature changes.
Q6: Will the pain go away on its own without treatment?
In most cases, persistent or extreme pain will not resolve without professional care. Ignoring it may lead to complications.
