Throbbing Tooth Pain: Causes and Fast Relief

A throbbing toothache is one of the most uncomfortable dental problems there is. The pain often pulses in time with your heartbeat, can spread to your jaw, ear or temple, and frequently gets worse when you lie down at night. Throbbing pain is usually a sign that the tissue inside the tooth — or the area around its root — is inflamed or infected, so it deserves attention even if it eases for a while.

This guide explains the most common causes of throbbing tooth pain, what you can do at home for fast, temporary relief, and when to call an emergency dentist.

What does throbbing tooth pain mean?

Each tooth has a soft inner core called the pulp, which contains nerves and blood vessels. When the pulp becomes inflamed, pressure builds inside the rigid walls of the tooth. Because the tooth can't swell outward, that pressure presses on the nerve — producing the pulsing, rhythmic pain people describe as "throbbing."

Throbbing pain can also come from the tissues around the root, such as the ligament and bone, when infection spreads beyond the tooth.

Common causes of throbbing tooth pain

Deep tooth decay

A cavity that has reached the inner layers of the tooth is the most common cause. Early decay rarely hurts; by the time it throbs, bacteria are often close to — or inside — the pulp.

Irreversible pulpitis

When pulp inflammation can no longer heal on its own, the pain tends to be spontaneous, lingering and worse at night. This usually needs root canal treatment to save the tooth.

Tooth abscess

An abscess is a pocket of pus caused by bacterial infection at the tip of the root or in the gum. It often causes intense throbbing, swelling, a bad taste and sometimes fever. Read more in our guide to tooth abscess symptoms and treatment.

Cracked or broken tooth

A crack can let bacteria reach the pulp and causes sharp pain when biting that can turn into a constant throb. See what to do about a broken tooth.

Recent dental work

Mild throbbing for a few days after a deep filling or crown can be normal as the nerve settles. Pain that gets stronger instead of better should be checked — learn how long a tooth should hurt after a filling.

Gum infection or wisdom teeth

A gum abscess, food trapped under the gum or a partially erupted wisdom tooth can create a deep, pulsing ache in the back of the mouth.

Sinus pressure and grinding

Upper back teeth sit close to the sinuses, so a sinus infection can make several teeth ache at once. Nighttime grinding (bruxism) can also leave teeth throbbing in the morning.

Why does tooth pain throb more at night?

When you lie down, more blood flows toward your head, increasing pressure inside an inflamed tooth. There are also fewer distractions, so the pain feels more intense. Pain that wakes you up is a strong sign the nerve is significantly inflamed and should be evaluated soon.

Tooth pain that comes and goes

Pain that flares and settles can still be serious. Early pulp inflammation, a cracked tooth or a slowly developing abscess can all cause intermittent pain. Sometimes pain stops completely because the nerve has died — but the infection remains and can spread. Don't assume the problem has resolved just because the throbbing has eased.

Fast toothache relief at home

These steps can ease throbbing pain temporarily while you arrange to see a dentist. They don't treat the cause.

• Take an over-the-counter pain reliever such as ibuprofen or acetaminophen, following the label and any advice from your doctor or pharmacist.
• Apply a cold compress to the outside of your cheek for 15 minutes at a time to reduce swelling and numb the area.
• Rinse with warm salt water (half a teaspoon of salt in a glass of warm water) to clean the area and soothe the gum.
• Keep your head elevated at night with an extra pillow to reduce pressure.
• Avoid very hot, cold, sweet or hard foods and chew on the other side.
• Try clove oil sparingly on a cotton ball — it contains eugenol, a natural numbing agent.

Never place aspirin directly on the gum, as it can burn the tissue.

When throbbing tooth pain is an emergency

Call an emergency dentist promptly if you have:

• Throbbing pain that lasts more than a day or two, or keeps you awake
• Swelling in your gum, face or jaw
• A bad taste, pus or a pimple-like bump on the gum
• Fever or feeling unwell
• Pain after an injury to the tooth

If swelling is spreading quickly, or you have difficulty breathing or swallowing, go to the nearest emergency room or call 911.

How a dentist treats throbbing tooth pain

At Magnolia Dentistry, Dr. Massaband first finds the source of the pain with an examination and X-rays. Depending on the cause, treatment may include:

• A filling or crown for decay or a cracked tooth
• Root canal treatment to remove inflamed or infected pulp and save the tooth
• Draining an abscess and, when needed, antibiotics
• Extraction if the tooth can't be saved, with a plan to replace it
• A night guard if grinding is contributing

Our Burbank office is open daily from 6 AM to 12 AM (midnight), with Dr. Massaband on call until midnight for dental emergencies.

Questions patients often ask

What causes throbbing tooth pain?

Throbbing pain usually comes from inflammation or infection inside the tooth (pulpitis) or around its root (an abscess). Deep decay, cracks, recent dental work, gum infections and sinus pressure are common causes.

How can I stop throbbing tooth pain fast?

For temporary relief, take an over-the-counter pain reliever as directed, use a cold compress, rinse with warm salt water and keep your head elevated. These steps ease pain but don't fix the cause, so see a dentist.

Why does my tooth throb at night?

Lying down increases blood flow and pressure in the head, which intensifies pain from an inflamed tooth. Pain that wakes you up is a sign you should see a dentist soon.

Can a throbbing tooth go away on its own?

The pain may fade, but the underlying problem usually doesn't. Sometimes pain stops because the nerve has died while the infection continues, so a dental exam is important.

Is throbbing tooth pain an emergency?

It's urgent if it's severe, lasts more than a day or two, or comes with swelling, fever or a bad taste. Swelling that affects breathing or swallowing needs emergency medical care.
