Dead Tooth

CONDITIONS

Save and strengthen dead teeth with advanced root canal therapy solutions.

About the treatment

A dead tooth, also known as a non-vital tooth, is a tooth that no longer receives blood supply. This can occur due to trauma, decay, or infection, leading to discolouration, pain, and potential infection spread if left untreated. A dead tooth does not heal on its own, and professional dental intervention is required to prevent complications.

Causes of a Dead Tooth

A tooth can die due to various factors that compromise its internal health, including:

  • Severe Tooth Decay – Untreated cavities allow bacteria to reach the pulp, leading to infection and pulp death.
  • Trauma or Injury – A strong impact from an accident or sports injury can damage blood vessels inside the tooth, cutting off its supply.
  • Repeated Dental Procedures – Extensive treatments on the same tooth can weaken its structure, increasing the risk of pulp damage.
  • Gum Disease & Infection – Advanced gum disease (periodontitis) can cause deep infections that lead to nerve and tissue death.
  • Bruxism (Teeth Grinding) – Constant grinding or clenching exerts excessive pressure, damaging the inner pulp over time.

Signs & Symptoms of a Dead Tooth

A dead tooth may not always cause pain immediately, but recognising early symptoms can prevent further complications.

  • Discolouration – The tooth may turn yellow, grey, brown, or black as the pulp deteriorates.
  • Tooth Sensitivity – Increased sensitivity to hot, cold, or pressure.
  • Pain or Discomfort – A dull ache or sharp pain due to infection and inflammation.
  • Bad Breath & Unpleasant Taste – Caused by bacterial buildup inside the dead tooth.
  • Swelling & Pus Formation – An infected dead tooth can lead to abscess formation, causing gum swelling.
  • Loose Tooth – A dead tooth may weaken and become loose over time.

Complications of an Untreated Dead Tooth

Ignoring a dead tooth can lead to serious oral health risks, including:

  • Spread of Infection – Bacteria can spread to the jawbone, gums, and neighbouring teeth.
  • Abscess Formation – A painful pocket of pus can develop, requiring urgent treatment.
  • Bone Loss – The jawbone around the affected tooth may deteriorate.
  • Bad Breath & Taste Issues – Infection can cause persistent halitosis (bad breath).
  • Tooth Loss – In severe cases, extraction becomes the only option.

Treatment Options for a Dead Tooth

  • Removes infected pulp while preserving the natural tooth structure.
  • Seals the tooth to prevent further bacterial invasion.
  • Often followed by a dental crown for strength and durability.
  • A severely decayed or infected tooth may need removal to prevent further issues.
  • Can be replaced with a dental implant, bridge, or denture to restore function.
  • A whitening procedure performed inside the dead tooth to restore a natural appearance.

Preventing Tooth Death

Although not all cases of dead teeth are avoidable, taking preventive steps can lower the risk.

  • Maintain good oral hygiene by brushing and flossing daily.
  • Visit the dentist regularly for early detection of decay or gum disease.
  • Wear a mouthguard if you play sports or grind your teeth at night.
  • Avoid sugary foods that increase cavity risk.
  • Seek prompt treatment for any dental pain or trauma.

Can a dead tooth be saved?

Yes, root canal treatment can save a dead tooth, but early intervention is crucial.

Not always. Some dead teeth cause no pain, while others may become infected and lead to severe discomfort.

A dead tooth can remain for months or even years, but eventually weakens and may cause infection.

A dead tooth can remain for months or even years, but eventually weakens and may cause infection.

Yes, as the tooth dies, it loses blood supply and can darken over time.

No, if treated early, a dead tooth can be saved with a root canal.

Yes, an untreated dead tooth can spread bacteria to nearby teeth, gums, and even the jawbone.

Untreated decay can lead to infections, abscesses, and eventual tooth loss.

Yes, if infected, a dead tooth can produce a foul smell and bad taste in the mouth.

A dentist will use X-rays, sensitivity tests, and visual examination to confirm if a tooth is dead.
