Severe Toothache at Night: Causes, Home Relief and Emergency Dental Treatments

A toothache at night can feel far worse than one during the day. When the house is quiet and you lie down, blood flow to your head increases, which can intensify pressure and throbbing in an inflamed tooth. There are also fewer distractions, so the pain seems louder.

If you are reading this in the middle of the night, take a breath. There are safe steps you can take right now, and effective emergency dental treatments available to fix the cause.

Why Toothache Is Often Worse at Night

Several factors combine after dark. Lying flat raises pressure around the tooth. Clenching or grinding while you sleep can aggravate a sore tooth. And without daily activity to occupy your mind, you notice pain more.

None of this means the problem is new. It often means an existing problem has reached the point where it can no longer be ignored.

Common Causes of Severe Toothache

Deep tooth decay. When decay reaches the pulp, the soft centre containing nerves and blood vessels, the pain can be intense and constant.

Dental abscess. A pocket of infection at the tooth root or in the gum causes throbbing pain, swelling and sometimes a bad taste.

Cracked tooth. A crack can cause sharp pain when biting or when the tooth is exposed to temperature changes.

Gum infection. Inflamed or infected gums can cause deep aching around a tooth.

Impacted wisdom tooth. A wisdom tooth that is trapped or partially erupted can cause pain, swelling and difficulty opening the mouth.

Failing filling or crown. Bacteria can get under a loose or damaged restoration and irritate the tooth.

Safe Steps You Can Take Tonight

While you wait to see an emergency dentist, these measures can provide temporary comfort:

• Rinse with warm salt water. Dissolve half a teaspoon of salt in a glass of warm water, swish gently and spit. This can help clean the area and soothe tissue.
• Take over-the-counter pain relief. Follow the directions on the packet and check with a pharmacist if you have other health conditions or take other medications.
• Apply a cold compress. Hold a cold pack wrapped in a cloth against the outside of your cheek for 15 minutes at a time.
• Keep your head elevated. Use an extra pillow to reduce pressure.
• Avoid trigger foods. Skip very hot, cold, sugary or chewy foods.
• Floss gently. Sometimes food trapped between teeth is the culprit.

What Not to Do

• Do not place aspirin directly against your gum. It can cause a painful chemical burn.
• Do not apply heat to a swollen face, as it may encourage infection to spread.
• Do not try to drain an abscess yourself.
• Do not ignore worsening symptoms in the hope they will pass.

Red Flags: When to Seek Help Immediately

Contact an emergency dentist in Liverpool as soon as possible if you have:

• Pain that is severe, constant or getting worse
• Swelling in your face, jaw or neck
• Fever or feeling generally unwell
• A bad taste or pus in your mouth
• Difficulty opening your mouth

If swelling makes it hard to breathe or swallow, or spreads towards your eye or throat, call 000 or go to a hospital emergency department straight away.

Emergency Dental Treatments for Toothache

Once your dentist finds the cause, treatment depends on what is going on:

Examination and X-rays. These show decay, bone changes and infection around the root.

Removing decay and placing a filling. If the problem is caught early, a filling may be enough.

Root canal treatment. If the pulp is infected, the dentist removes it, cleans the inside of the tooth and seals it. This relieves pain and saves the tooth.

Draining an abscess. Releasing pus reduces pressure and pain quickly.

Antibiotics. These may be prescribed where there is spreading infection, usually alongside dental treatment rather than instead of it.

Extraction. If a tooth is too damaged to save, removing it may be the best way to end the pain and infection.

Temporary dressing. Sometimes the dentist will calm the tooth with a temporary treatment and schedule the definitive treatment shortly afterwards.

What to Expect at Your Appointment

Your dentist will ask about your symptoms, review your medical history and examine the tooth. Local anaesthetic is used so treatment is comfortable. Most people are surprised how quickly the pain settles once the cause is treated.

Afterwards you will receive instructions on pain relief, eating, oral hygiene and any follow-up visits. Following this advice helps healing and prevents the problem returning.

Why Pain Suddenly Stopping Is Not Always Good News

If severe toothache suddenly disappears, it can mean the nerve inside the tooth has died. The infection may still be present and can continue to spread. You should still see a dentist, even if the pain has gone.

Preventing Future Toothaches

• Brush twice daily with fluoride toothpaste and clean between your teeth daily
• Limit sugary snacks and drinks
• Visit your dentist for regular check-ups and cleans
• Treat small cavities before they grow
• Wear a night guard if you grind your teeth
