Common Causes of Toothaches & When to Seek Treatment

A toothache may start as a dull discomfort and quickly escalate to a sharp, throbbing pain that disrupts daily life. While occasional sensitivity may not be alarming, persistent or severe tooth pain can be a sign of an underlying issue that requires professional attention. For instance, if you experience a toothache at night, it might feel more intense due to fewer distractions and increased blood flow to the head while lying down. Common concerns discussed in Toothache at Night? The Shocking Reasons It Hits Harder and What You Can Do Before Sunrise. Understanding what causes tooth pain, recognizing symptoms, and knowing when to see a dentist can help you prevent complications and protect your oral health.

In this guide, we’ll explore the most common causes of toothaches, how to identify severe symptoms, how to relieve a toothache, and when you should see a dentist for tooth pain.

What Causes Tooth Pain?

Tooth pain often originates from inflammation or irritation in the nerves within the tooth or surrounding tissues. This can be triggered by a variety of factors, ranging from cavities and gum disease to cracked teeth or even sinus infections. In fact, gum disease is one of the most overlooked causes of persistent tooth discomfort, and it's often linked to poor oral hygiene or untreated plaque buildup.

1. Tooth Decay (Cavities)

Tooth decay is one of the most prevalent causes of dental pain. Cavities occur when plaque, a sticky film of bacteria, produces acids that erode your tooth enamel. As the decay progresses, it can reach the dentin or even the pulp, leading to sensitivity and pain.

Signs of cavity-related tooth pain:

• Sensitivity to hot, cold, or sweet foods
• A visible hole or dark spot on the tooth
• Mild to severe pain, especially when chewing

If you're wondering what causes tooth pain that feels like a dull ache, cavities are often to blame. Early-stage decay may not cause any pain, which is why routine checkups are vital.

2. Gum Disease (Gingivitis and Periodontitis)

Gum disease begins as gingivitis, red, swollen, or bleeding gums due to plaque accumulation. If left untreated, it can advance to periodontitis, a more severe condition that damages the supporting bone and ligaments of your teeth. Gum recession can expose tooth roots, leading to pain and sensitivity. To understand the early warning signs and know when it's time to act, refer to our detailed guide: Signs of Gum Disease: When to Seek Treatment for Gingivitis and Periodontitis.

Symptoms of gum disease:

• Swollen, bleeding gums
• Persistent bad breath
• Loose teeth or tooth mobility
• Tooth pain near the gumline

When trying to determine what causes tooth pain in the absence of cavities, gum disease is a common culprit.

3. Dental Abscess

A dental abscess is a severe tooth infection that forms when bacteria invade the pulp or surrounding gum tissue. This condition can result in severe, pulsating pain and swelling. If left untreated, What Happens if You Ignore a Dental Abscess?. Becomes a critical concern, as the infection can spread beyond the tooth to other areas of the body, potentially leading to systemic issues like fever, swollen lymph nodes, and even life-threatening complications.

How do I know if I have a dental abscess?

• Severe, constant tooth pain
• Swelling in the face or jaw
• Fever or a bad taste in your mouth
• Pain that radiates to your ear or neck
• Visible pus or a bump on the gums

If you experience any of the above signs, it’s crucial to seek immediate dental care. Ignoring an abscess can lead to complications such as bone loss or even sepsis.

4. Tooth Sensitivity

Tooth sensitivity is a sharp, sudden pain in response to temperature changes or sweet foods. This often stems from worn enamel, exposed dentin, or receding gums.

Common causes of sensitivity:

• Over-brushing or hard-bristled toothbrush use
• Gum recession
• Tooth grinding (bruxism)
• Acidic foods and beverages

Using a sensitivity-specific toothpaste and visiting your dentist for a proper diagnosis are key steps in managing this condition.

5. Cracked or Fractured Tooth

Cracks in your tooth, even those too small to see, can cause intermittent pain when chewing or when the tooth is exposed to extreme temperatures. These cracks may expose the nerve inside the tooth, leading to sensitivity and pain.

Signs of a cracked tooth:

• Sharp pain when biting down
• Pain that comes and goes
• Sensitivity to hot or cold foods

A cracked tooth needs prompt attention to prevent infection or nerve damage. A crown, filling, or root canal may be required depending on the severity.

6. Impacted Wisdom Teeth

Wisdom teeth often emerge in late adolescence or early adulthood, but sometimes they don’t have enough space to erupt fully. These impacted wisdom teeth can cause pain, swelling, and even infection, making timely treatment essential. In such cases, a procedure like Wisdom Teeth Removal may be recommended to prevent further complications and protect overall oral health.

Symptoms of impacted teeth:

• Pain in the back of the jaw or mouth
• Difficulty opening the mouth
• Swollen, red gums near the molars
• Headaches or jaw stiffness

Your dentist may recommend wisdom tooth extraction if pain persists or infection develops.

7. Sinus Infection-Related Tooth Pain

Surprisingly, not all toothaches originate from the mouth. Sinus infections can cause pressure that radiates pain to your upper molars. This type of discomfort is often confused with a dental issue.

Symptoms of sinus-related toothache:

• Facial pressure around the cheeks or forehead
• Nasal congestion or post-nasal drip
• Pain that worsens when bending forward
• No specific tooth showing decay or trauma

What causes tooth pain in the upper teeth along with sinus pressure? A sinus infection might be the answer.

How Do I Know If I Have a Dental Abscess?

Dental abscesses are among the most serious causes of tooth pain and must be treated quickly to avoid complications.

Here’s a quick checklist:

• Is your tooth pain intense, constant, and throbbing?
• Do you feel swelling in the face or jaw?
• Is there a fever, bad breath, or pus?
• Do you feel pain when lying down or chewing?
• Is there a visible bump on your gums near the affected tooth?

If you answered yes to any of these, you might have a dental abscess. Call your dentist or an emergency dental clinic immediately to get treatment, which may involve draining the abscess or a root canal procedure.
