Sudden Tooth Pain? Here’s What Might Be The Cause

Few things can ruin your day faster than sudden tooth pain. Whether it’s a sharp jolt while drinking something cold or a throbbing ache that keeps you up at night, unexpected dental discomfort can be both alarming and frustrating. The good news? Most causes of sudden tooth pain are treatable—especially when caught early. At Dr. Douglas Geiger, DMD in Pineville, NC, we believe that understanding the source of your pain is the first step toward relief. In this blog, we’ll break down some of the most common reasons for sudden tooth pain and what you can do about it.

Why Does My Tooth Hurt All of a Sudden?

Tooth pain doesn’t always come with a warning. Even if you haven’t had a recent injury or dental procedure, pain can suddenly appear due to a variety of factors. Let’s take a closer look at the most common causes of sudden tooth pain.

1. Tooth Decay

One of the leading causes of sudden tooth pain is tooth decay—also known as a cavity. When bacteria in your mouth feed on sugar and starches, they produce acids that eat away at your enamel. Over time, this creates holes in the tooth that can reach the inner layers, where the nerves are located.

Signs of Decay:

• Sharp pain when eating or drinking something sweet
• Sensitivity to hot or cold temperature
• Visible dark spots or holes on the tooth

If you think a cavity might be the culprit, don’t wait. The longer it goes untreated, the deeper the decay can spread.

2. Cracked or Chipped Tooth

Did you bite down on something hard recently? Even a small crack or chip can expose the sensitive inner part of the tooth, leading to sudden pain.

Symptoms of a Cracked Tooth:

• Sharp pain when chewing
• Intermittent discomfort
• Sensitivity to cold or air

Sometimes, cracks are invisible to the naked eye and only show up on dental X-rays. That’s why it’s important to schedule a dental exam if you suspect a cracked tooth.

3. Gum Recession

Gum recession occurs when your gum tissue pulls back, exposing the tooth roots. Since roots aren’t protected by tooth enamel, they can be extremely sensitive.

What Causes Gum Recession:

• Brushing too hard
• Gum disease
• Grinding your teeth
• Aging

This condition may lead to sudden sensitivity, especially when eating or drinking something cold.

4. Abscessed Tooth

An abscess is a pocket of pus caused by a bacterial infection. It can develop when a cavity or cracked tooth goes untreated and bacteria reach the pulp of the tooth.

Symptoms of an Abscess:

• Intense, throbbing pain that doesn’t go away
• Inflammation of the gums or face
• Fever or a bad taste in your mouth

An abscessed tooth is a dental emergency and needs prompt treatment. If you’re experiencing these symptoms, call our Pineville office right away.

5. Sinus Infection

Believe it or not, not all tooth pain starts in the mouth. If you have a sinus infection, the pressure in your sinuses can affect the upper back teeth and cause pain that feels like a toothache.

How to Tell:

• Pain in multiple upper teeth
• Nasal congestion or pressure
• Relief when sinuses are cleared

If your tooth pain comes with cold or allergy symptoms, a sinus infection could be the root cause.

6. Teeth Grinding (Bruxism)

Grinding your teeth—especially at night—can cause wear and tear on the enamel, lead to cracks, and even damage the nerves inside your teeth.

Signs of Grinding:

• Sore jaw or headaches in the morning
• Flattened or worn-down teeth
• Sudden tooth sensitivity or pain

A custom biteguard from Dr. Geiger’s office can help protect your teeth while you sleep.

7. Dental Work Sensitivity

If you’ve recently had a filling, crown, or other dental treatment, mild sensitivity or pain is common in the days afterward. However, if the pain is severe or lingers for more than a week, it may indicate a problem with the restoration. Always follow up with your dentist if pain continues or worsens after treatment.

How to Relieve Tooth Pain at Home (Temporarily)

While seeing a dentist is the best way to treat the underlying cause of tooth pain, there are a few things you can try at home to ease the discomfort in the meantime:

• Rinse with warm salt water
• Take over-the-counter pain medication (ibuprofen or acetaminophen)
• Use an ice pack on the outside of your cheek
• Avoid very hot, cold, or sugary foods
• Try a toothpaste designed for sensitive teeth

These home remedies are not long-term solutions, but they can offer short-term relief until you get professional care.

When to Call the Dentist

You should always seek professional help and a prompt evaluation for tooth pain that:

• Lasts more than a day or two
• Is severe or throbbing
• Is accompanied by swelling, fever, or a bad taste
• Makes it hard to eat, sleep, or focus
• Happens suddenly without an obvious cause
