Healthy teeth are vital for a radiant smile and overall well-being. However, sometimes a tooth can die unexpectedly. It is crucial to understand the causes, signs, and treatment options for a dead tooth. In this article, we will explore the concept of a dead tooth, its causes, and what can be done by your dentist to address this issue effectively. 

What is a Dead Tooth?

A dead tooth refers to a tooth that no longer receives blood supply. Also known as a “non-vital” tooth.  Allowing a dead tooth to remain untreated can lead to hidden infections and potential health complications. 

Causes of a Dead Tooth

Tooth decay, cracks and injuries are the primary factors that can cause a tooth to die. Tooth decay, often known as a cavity, starts as an acidic erosion of the outermost layer (enamel). If left untreated, the cavity deepens and can reach the softer dentin tissue, leading to an infection in the pulp where the nerve resides. Tooth injuries, such as falls or trauma, can disrupt blood supply and cause a tooth to die either suddenly or gradually. Cracks in the enamel or restorations can allow harmful bacteria to leak into the tooth and eventually cause the tooth to become non-vital. 

Can a Dead Tooth Be Saved?

While it is not possible to restore the pulp of a dead tooth to its normal, healthy state, timely treatment can help preserve the tooth’s structure. Root canal treatment is often recommended for non-vital teeth. During this procedure, the infected soft tissue (pulp) is removed, and the root canal is cleaned and sealed to prevent reinfection. In most cases, a dental crown will be necessary to protect the treated tooth from further damage. 

Duration of Tooth Death

Estimating the exact time it takes for a tooth to die is challenging. When a tooth dies due to an injury, blood supply may diminish within a day, a few weeks, or several months. If you notice signs of a dying tooth, such as discoloration or pain, it is crucial to seek immediate dental attention. 

Can a Dead Tooth Be Revived?

At present, there is no known method to restore blood flow to a severely damaged or diseased tooth. Seeking prompt dental care is essential when a tooth shows signs of dying. While early intervention can help preserve natural tooth structure, it cannot revive the blood supply to the tooth.  

Does a Dead Tooth Cause Odor?

A dead tooth itself does not cause bad breath. However, if a dead tooth is left untreated, it can lead to an abscess—an infection that forms at the tooth’s root or in the adjacent gums. Symptoms of an abscess include bad breath, an unpleasant taste in the mouth, and sometimes, a pimple-like sore on the gums. Timely treatment is necessary to prevent potential complications. 

Can a Tooth Nerve Heal Itself?

Teeth nerves have the potential to heal, but it depends on the extent of the damage. Spontaneous or hot food-related pain often indicates irreversible damage. It is advisable to seek dental care immediately if you experience pain when consuming cold items, as early intervention provides a better chance of saving the tooth with a filling or crown. 

Does Tooth Nerve Pain Subside?

Nerve pain caused by a cavity or tooth injury typically subsides eventually. However, the pain diminishes because the nerve and the tooth have died. Over time, the tooth becomes brittle and prone to breaking. Additionally, an abscess may develop beneath the gums, leading to intensified pain and potential complications.
