Common Causes of Toothache

Toothaches can arise from various dental and non-dental issues. Here are some of the most common causes:

Dental Decay

Tooth decay is perhaps the most frequent cause of toothache. When bacteria break down food particles, they produce acid that erodes tooth enamel, leading to cavities. According to the CDC, more than 90% of adults have had dental caries in their permanent teeth.

Gum Disease

Periodontal disease can cause persistent tooth pain, especially when:

  1. Gums become inflamed
  2. Pockets form around teeth
  3. Bone loss occurs
  4. Teeth become loose

Tooth Abscess

An abscessed tooth is a pocket of pus caused by a bacterial infection. It can occur at different regions of the tooth and cause severe, throbbing pain that may radiate to the jawbone, neck, or ear.

Dental Trauma

Physical injury to teeth can cause immediate and lasting pain through:

  • Cracked or chipped teeth
  • Loose teeth
  • Damaged fillings
  • Sports injuries

Other Causes

  • Tooth Sensitivity: Worn enamel or exposed root surfaces can lead to sensitivity
  • Sinus Infection: Can cause pain in upper teeth due to sinus cavity proximity

Duration of a Toothache

The duration varies significantly depending on its cause:

  • Temporary sensitivity: 1-2 days
  • Sinus-related tooth pain: 7-10 days
  • Cavity-related pain: Ongoing until treated
  • Infection/abscess: Continuous and worsening without intervention

Worn tooth enamel, exposed root surfaces, or recent dental procedures can all lead to temporary sensitivity to hot, cold, or sweet stimuli.

When to Seek Professional Help

Immediate dental attention is necessary if you experience:

  • Severe pain lasting more than 1-2 days
  • Swelling in the face or jaw
  • Fever accompanying tooth pain
  • Difficulty breathing or swallowing
  • Pain when biting down

Treatment Options

Treatment varies based on the underlying cause:

ConditionCommon Treatment
CavityFilling or crown
InfectionRoot canal or antibiotics
Cracked toothCrown or bonding
SensitivityDesensitizing toothpaste

Prevention Strategies

Daily Oral Care

  • Stay hydrated
  • Schedule regular dental check-ups

Remember that while some toothaches may be temporary, persistent pain usually indicates a problem requiring professional attention. Dental issues typically worsen over time and can lead to more serious complications if left untreated.
