Dead Tooth Signs, Treatment, Pain, and Management

Dentin and pulp are both soft tissue, while enamel and dentin are both hard tissue in the tooth. My nerves were well-innervated thanks to the pulpal layer’s blood supply. A dead tooth is one whose nerves have died as a result of decay or injury and which no longer receives blood supply, thus the name.

A dead tooth nerve is referred to as “necrotic pulp.” The term “non-vital tooth” can refer to either a dead or non-functioning tooth.

The tooth will eventually fall out on its own, but you shouldn’t wait for it to do so because it could be harmful and infectious to the jaw and other teeth if you do wait. If you suspect you have a dead tooth, look for the following signs.


A dental professional should be consulted for help in determining the cause of a dead tooth. It is possible to self-diagnose a dead tooth by looking for discoloration and/or pain in the gums or the tooth itself.

First, there’s a discoloration.

However, a person’s diet and oral hygiene can also influence the colour of their teeth. Foods that stain teeth, like blueberries and coffee, can cause a yellowed smile.

In contrast, teeth that are dying or dead can appear yellow, light brown or grey, or even black. Leaving the discoloration unattended will lead to further tooth decay and nerve death. The bruising effect is caused by the death of red blood cells, which results in a change in colour.

Secondly, there is a lot of discomfort.

A tooth that is either dead or dying can cause pain that ranges from mild to excruciating, depending on the severity of the infection or nerve damage. Additionally, there are other indicators of infection.


Why and How Does One Feel Pain if The Nerve is Already Dead?

The answer to this question is:

Pus is formed in the tooth’s pulp cavity by bacteria and dead nerve remnants, which exerts pressure on the periodontal membrane outside the tooth and causes discomfort.

We can say that the pain is not coming from inside the tooth, but rather from the periodontal membrane, which is made up of extremely sensitive nerve endings.

When a Tooth Dies, Why is That?

The death of a tooth can occur in a matter of days, weeks, or even months.

A traumatic injury, such as one sustained while participating in sports or in an accident, can result in death. Blood vessels rupture or the tooth’s blood supply is obstructed as a result. The pulp’s nerves and tissues die because of a lack of blood supply.

Cavities can develop for a variety of reasons, the most common of which is tooth decay, which slowly eats away at the protective enamel layer. If the cavities are not treated, the pulp can become infected, cutting off the blood supply and causing nerves to die.

In the pulp, there will be an inflammatory reaction, but it will not last for very long. As time passes, the pulp will become increasingly compressed. This is extremely painful as well. Poor oral hygiene is to blame for the contamination.


X-rays are useful in determining if a tooth is dying. When a tooth hurts or appears discoloured, it’s best to see a dentist right away. Regular dental checkups are essential, as well as after an injury. The sooner treatment can begin, the better.


There is a high risk of spreading bacteria and infection from the dying tooth to the rest of the teeth, as well as to the gums and the jawbone. ‘ The sooner it is treated, the better the chance of avoiding further tooth loss.

In most cases, root canal and extraction are the most common treatments.

For example, a root canal.

Using small instruments, the dentist creates an opening in the tooth to access the pulp. Afterwards, the pulp is removed and sanitised. In order to close the root canal, the dentist will fill and seal it, and then place a long-term filling in the gap.

Because a root canal-treated tooth can become brittle over time, it’s best to have a crown placed on top of it afterward, especially on the back teeth.

The tooth is given additional support by the splint. A crown is simply a cap that is affixed to the tooth. In order to permanently cover the tooth with a crown, the dentist will have to remove a portion of the natural tooth. To keep it from being noticed, it’s painted the same shade of white as the rest of the teeth.

Tooth-bleaching agents can be used in cases where a crown is not required. Anterior teeth are the most common candidates. Aesthetically, you may want to consider getting a porcelain veneer.


The dentist may recommend tooth extraction if the tooth is too badly damaged to be repaired. It’s a low-cost, no-hassle process.

The dentist will use this method to remove the tooth in its entirety. Implants, bridges, and prosthetic teeth can all be used to replace a missing tooth. They can be brought up in conversation with the dentist along with any other concerns the patient may have.

Relieve of Suffering

Pain can range from mild to excruciating. Prior to treatment, there are steps that can be taken to alleviate some of the pain. Inflammation and pain can be avoided by limiting the consumption of hot beverages.

You can take ibuprofen or acetaminophen, which are anti-inflammatory medications. It is better to avoid eating hard foods that cause more pain by increasing the pressure on the digestive system.

It is possible to use a cold compress. It’s also possible to get some relief from the discomfort by using topical analgesics. These methods are advised till the treatment does not begin but professional help is always preferred.

Preventative Measures

However, there is always a chance of something going wrong, and to avoid this, certain precautions can be taken.

1. Good oral hygiene is absolutely essential. It is recommended that you brush your teeth at least twice a day. The use of an interdental brush or floss, at least once a day, is essential as well.

2. Second, a regular dental check-up. Preventative measures can be taken before the pulp begins to decay.

3. Use of mouth guards or gum shields to prevent mechanical trauma while participating in sports or other activities. The practise of grinding one’s teeth or using one’s mouth to open things should be discouraged.

The consumption of sugary, sweet foods is a leading cause of dental caries. Maintaining a nutritious diet can help lower the danger. Infections can be washed away from teeth by drinking plenty of water on a daily basis.


The pulp of a tooth that has died is known as a “dead” tooth. Tooth decay and physical injury are just two examples of possible triggers.

To avoid the loss of a tooth, the diagnosis and treatment should be carried out as soon as possible. Depending on the extent of the damage, root canals or extractions may be necessary. In the meantime, pain can be controlled.

Taking preventative measures and going to the dentist on a regular basis is the best way to avoid damage in the first place.
