Tooth and Nerve Pain: Causes, Symptoms, and When to See a Dentist

Tooth and nerve pain usually signals an issue with the innermost part of the tooth the pulp where the nerves and blood vessels live. When this area is affected by decay, trauma, or infection, it can lead to anything from a dull ache to sharp, intense pain. Understanding the causes and symptoms can help you decide when it’s time to seek dental care.

In this blog, we’ll explain what triggers tooth and nerve pain, how to recognise the signs, and when to book an appointment with your dentist.

What Causes Tooth and Nerve Pain?

Tooth and nerve pain often stems from issues affecting the dental pulp. Below are the most common causes:

• Tooth Decay: Cavities can deepen over time, reaching the nerve and causing significant discomfort.

• Cracked or Chipped Teeth: Even small cracks can expose nerves and lead to sensitivity or pain.

• Dental Abscess: Infections near the tooth root form pockets of pus, triggering throbbing pain.

• Gum Disease: Advanced periodontitis can affect tooth roots and surrounding nerves.

• Teeth Grinding (Bruxism): Excessive pressure from clenching or grinding can irritate nerves.

• Receding Gums: This can expose the tooth root, increasing sensitivity and pain.

What Are the Symptoms of Tooth and Nerve Pain?

Pain involving the nerve typically has specific characteristics. These include:

• Sharp, stabbing pain when eating or drinking hot, cold, or sweet items

• Persistent throbbing or aching, especially at night

• Pain when chewing or applying pressure

• Swollen or red gums around the affected tooth

• A bad taste or smell in the mouth, which may point to infection

When Should You See a Dentist?

You don’t need to wait until the pain becomes unbearable. See your dentist if you experience any of the following:

• Pain that lasts more than 48 hours

• A sudden, severe toothache that interferes with eating or sleeping

• Swelling in your gums, cheek, or face

• Fever or feeling generally unwell

• Difficulty swallowing or opening your mouth fully

Prompt treatment can prevent further complications, including infection spread or tooth loss.

How Is Tooth and Nerve Pain Treated?

Treatment depends on the underlying cause, but common options include:

Cause	Treatment Options
Tooth decay	Filling, inlay/onlay, or root canal
Cracked or chipped tooth	Bonding, crown, or extraction (if severe)
Dental abscess	Root canal or extraction, plus antibiotics
Gum disease	Deep cleaning, antibiotics, or surgical treatment
Exposed tooth root	Desensitising agents or gum grafting

Your dentist will assess your symptoms and recommend a personalised plan.
