Toothache Guide
A toothache can range from mild discomfort to severe, throbbing pain that makes it hard to eat, sleep, or concentrate. Most toothaches are caused by a problem inside the tooth or surrounding tissues, and they rarely improve on their own for long.
This guide covers the most common causes, what you can safely do for temporary relief, and when it is time to see a dentist.
Common causes of toothache
The majority of toothaches come from one of these issues:
- Tooth decay (cavity) – Bacteria reach the sensitive inner layers of the tooth.
- Pulpitis or infection – Inflammation or infection of the nerve inside the tooth.
- Cracked or fractured tooth – A crack can expose the nerve or allow bacteria to enter.
- Failed or leaking filling or crown – Old restorations can allow decay to restart underneath.
- Gum disease or abscess – Infection in the supporting tissues around the tooth.
- Bruxism (grinding or clenching) – Excessive force can cause sensitivity or cracks.
Less commonly, pain can be referred from the jaw joint, sinuses, or other structures, but dental causes are by far the most frequent.
Typical symptoms
Patients often describe:
- Sharp, throbbing, or constant pain
- Sensitivity to hot, cold, or sweet foods and drinks
- Pain when biting or chewing
- Swelling of the gum or face
- A bad taste or drainage near the tooth
Pain that wakes you at night or that is accompanied by swelling or fever usually indicates a more advanced problem.
What you can do for temporary relief
These measures can reduce discomfort while you arrange professional care. They do not treat the underlying cause:
- Rinse gently with warm salt water
- Take an over-the-counter pain reliever (ibuprofen or acetaminophen) as directed on the label
- Apply a cold compress to the outside of the cheek for 10–15 minutes
- Avoid very hot, cold, or sugary foods and drinks
- Keep the area clean — gently brush and floss around the painful tooth
Do not place aspirin directly on the gum; it can burn the tissue.
When you should see a dentist
Contact a dentist promptly if:
- The pain lasts more than 24–48 hours
- The pain is severe or keeps you from sleeping
- You notice swelling of the face, gum, or neck
- You develop a fever or feel generally unwell
- There is pus or a foul taste coming from the area
Waiting usually allows the problem to progress and can turn a relatively simple treatment into a more complex one.
How we diagnose and treat toothache at Smiles Peru
We begin with a clinical examination and, when needed, digital X-rays or 3D imaging to identify the exact source of the pain. Treatment depends on the diagnosis and may include:
- A filling or replacement of an old restoration
- Root canal treatment if the nerve is irreversibly inflamed or infected
- Drainage of an abscess and appropriate antibiotics when indicated
- A crown to protect a cracked or heavily restored tooth
- In some cases, extraction and discussion of replacement options
Our goal is always to preserve the tooth when it is clinically reasonable to do so.
