Why Toothaches Get Worse at Night
There is a reason your toothache seems to wait until bedtime to flare up. Several factors combine to make tooth pain more intense after dark:
- Increased blood flow to the head: When you lie flat, gravity no longer helps direct blood away from your head. The resulting increase in blood pressure around the inflamed tooth or gum tissue intensifies the throbbing pain. This is the single biggest reason toothaches feel worse at night.
- Fewer distractions: During the day, work, conversations, and daily activities keep your mind occupied. At night, in a quiet room with nothing else to focus on, your brain zeroes in on pain signals that you might have been able to tolerate during the day.
- Teeth grinding (bruxism): Many people clench or grind their teeth during sleep without realising it. This places enormous pressure on already-sensitive teeth and can cause or worsen tooth pain overnight. If you wake up with a sore jaw or headache in addition to tooth pain, bruxism may be a contributing factor.
Common Causes of Throbbing Tooth Pain
A throbbing toothache is your body's warning signal that something is wrong. Here are the most common causes:
- Tooth decay or a deep cavity: When a cavity reaches the inner layers of your tooth (the dentin or pulp), it exposes sensitive nerve endings. The deeper the decay, the more intense the pain. Read our guide on how to prevent cavities and tooth decay for tips on stopping decay early.
- Dental abscess or infection: An untreated cavity or crack can allow bacteria to reach the tooth pulp, causing an infection. The resulting abscess — a pocket of pus — creates pressure and severe, throbbing pain that often radiates to the jaw, ear, or neck.
- Cracked or fractured tooth: A crack in the tooth may not always be visible, but it can expose the nerve inside. You might notice sharp pain when biting down, which turns into a dull throb at night when the tooth is no longer under direct pressure.
- Gum disease: Advanced gum disease (periodontitis) causes the gums to pull away from the teeth, creating pockets where bacteria thrive. This leads to inflammation, tenderness, and sometimes throbbing pain. Learn to recognise the early signs of gum disease, and visit our gum treatment page if you are experiencing symptoms.
- Wisdom tooth eruption or impaction: Wisdom teeth that are partially erupted or impacted (stuck beneath the gum or bone) can cause significant pain, especially at night. Swelling, inflammation, and pressure on neighbouring teeth all contribute. If you suspect your wisdom teeth are the cause, learn more about wisdom tooth surgery.
- Recent dental procedure: Some throbbing after a filling, crown, or extraction is normal and usually subsides within a few days. If the pain worsens instead of improving, or lasts more than a week, contact your dentist.
What You Can Do Tonight for Relief
While these home remedies can provide temporary relief, they do not address the underlying cause. See a dentist as soon as possible for a proper diagnosis and treatment.
- Take an over-the-counter painkiller: Ibuprofen is often recommended because it reduces both pain and inflammation. Paracetamol is another option. Follow the dosage instructions on the packaging and do not exceed the recommended amount.
- Elevate your head: Prop yourself up with an extra pillow or two. Keeping your head above your heart reduces blood flow to the area and can noticeably ease the throbbing.
- Apply a cold compress: Wrap ice or a cold pack in a towel and hold it against the outside of your cheek near the sore tooth. Apply for 15–20 minutes at a time. The cold helps numb the area and reduce swelling.
- Rinse with warm salt water: Dissolve half a teaspoon of salt in a glass of warm water and gently swish it around your mouth. Salt water helps reduce bacteria and soothe inflamed gums.
- Avoid trigger foods before bed: Stay away from very hot, cold, or sugary food and drinks in the evening, as these can aggravate sensitive teeth and intensify pain.
Important: These are temporary measures only. A throbbing toothache usually signals a problem that will not resolve on its own. Delaying treatment can allow the condition to worsen, potentially leading to more pain, infection, or tooth loss.
When to See a Dentist Urgently
Some toothache situations require prompt professional attention. See a dentist as soon as possible — ideally the same day — if you experience any of the following:
- Pain lasting more than 1–2 days that does not respond to over-the-counter painkillers
- Swelling in the face, jaw, or gums — this may indicate an abscess or spreading infection
- Fever — a sign that your body is fighting an infection
- Difficulty swallowing or breathing — seek immediate medical attention
- A broken or knocked-out tooth — time is critical for saving the tooth

How Your Dentist Will Treat Throbbing Tooth Pain
Treatment depends entirely on the cause. At your appointment, your dentist will carry out a thorough examination and take X-rays to diagnose the problem accurately. Here is what treatment may look like depending on the diagnosis:
- Fillings for tooth decay: If a cavity is causing your pain, your dentist will remove the decayed portion and place a filling to seal the tooth and protect it from further damage.
- Root canal treatment for infection: When decay or damage has reached the tooth pulp (the nerve), a root canal may be needed to remove the infected tissue, clean the canals, and save the tooth. For patients aged 60 and above, root canal treatment is eligible for Flexi-MediSave ($200 per year).
- Extraction if the tooth cannot be saved: In severe cases, the tooth may need to be removed. Wisdom tooth surgical extraction ranges from $350–$1,250 per tooth and is 100% Medisave claimable up to $1,250 per tooth.
- Gum treatment: If gum disease is the cause, your dentist may recommend scaling and root planing or gum surgery (from $500 before GST, Medisave claimable) to address the infection and prevent further damage.
