A dead tooth is a tooth that no longer receives blood flow. It may remain in the mouth for weeks, months, or even years. However, leaving it untreated can cause serious dental problems. This article explains how long a dead tooth can stay in your mouth, what happens if you ignore it, and what treatment options are available.
What is a Dead Tooth?
Teeth are living structures made up of different layers. The outer layer, called enamel, protects the tooth from damage. Beneath it lies dentin, followed by the pulp, which contains blood vessels and nerves. If you need expert dental care to keep your teeth healthy, an NHS Dentist in Aberdeen can provide professional check-ups and treatments.
When a tooth suffers severe damage or infection, the blood supply stops, causing the tooth to die. This can happen due to:
- Tooth decay – A deep cavity that reaches the pulp.
- Trauma – A strong impact that cuts off blood flow.
- Gum disease – Severe infection that damages the tooth’s support.
Once the blood supply is lost, the tooth is no longer alive. This is why dentists call it a non-vital tooth or necrotic pulp.
How Long Can a Dead Tooth Stay in the Mouth?
A dead tooth does not fall out immediately. It may remain in the mouth for days, weeks, months, or even years. The length of time depends on:
- Extent of damage – A severely infected tooth will break down faster.
- Presence of infection – Bacteria can weaken the tooth and surrounding bone.
- Oral hygiene – Poor cleaning speeds up decay and infection.
- Immune system – The body’s response may cause swelling or an abscess.
Even if a dead tooth does not cause pain at first, it will eventually lead to problems. It is always best to see a dentist as soon as possible.
Signs of a Dead Tooth
It is not always easy to tell if a tooth is dead. Some dead teeth do not hurt at all. However, common signs include:
1. Tooth Discolouration
A dead tooth may change colour over time. Healthy teeth are white or slightly yellow. A dead tooth can turn grey, brown, or black as blood cells inside break down.
2. Pain or Discomfort
A dead tooth does not always cause pain. However, if the nerve endings around the tooth become irritated, it can lead to discomfort, pressure, or aching.
3. Bad Breath or a Bad Taste
A dead tooth can collect bacteria and food debris, leading to bad breath or a foul taste in the mouth.
4. Swelling or Infection
If bacteria spread beyond the tooth, it can cause swelling in the gums, jaw, or face. This may lead to an abscess, a painful pocket of pus.
What Happens if You Leave a Dead Tooth Untreated?
Ignoring a dead tooth can lead to serious problems. These include:
1. Spread of Infection
Bacteria from a dead tooth can spread to nearby teeth, gums, and even the jawbone. In severe cases, it may enter the bloodstream, leading to serious health risks.
2. Weakening of the Jawbone
The body stops supporting a dead tooth, causing the jawbone to shrink over time. This can lead to bone loss and changes in facial structure.
3. Tooth Loss
A dead tooth may stay in the mouth for a while, but it will eventually become loose and fall out. By this stage, surrounding teeth may already be affected.
4. Severe Pain and Swelling
An untreated infection can cause a painful abscess, leading to swelling, fever, and difficulty chewing.
For these reasons, it is best to seek treatment as soon as possible.
Treatment Options for a Dead Tooth
There are two main treatments for a dead tooth:
1. Root Canal Treatment
A root canal can save the tooth by removing the dead pulp and sealing the inside. This helps prevent infection and allows the tooth to stay in place. A crown is often placed over the tooth to restore its appearance and strength.
2. Tooth Extraction
If the tooth is too damaged, removal may be the best option. Once extracted, it can be replaced with a bridge, denture, or dental implant to maintain function and appearance.
The right treatment depends on the condition of the tooth and surrounding gums. A dentist will assess the situation and recommend the best option.
How to Prevent a Dead Tooth
Preventing a dead tooth is easier than treating one. Here are some tips:
- Brush and floss daily – Keep teeth clean to prevent decay and infection.
- Avoid sugary foods – Sugar feeds bacteria that cause cavities.
- Wear a mouthguard – Protect your teeth during sports or physical activities.
- Visit the dentist regularly – Early detection can prevent tooth death.
- Treat cavities early – Fillings and crowns can stop decay from reaching the pulp.
A little care can go a long way in keeping your teeth healthy.
Final Thoughts
A dead tooth may stay in the mouth for weeks, months, or even years, but that does not mean it should be ignored. Without treatment, it can cause infection, pain, and damage to other teeth.
If you notice discolouration, pain, or bad breath, see a dentist as soon as possible. Early treatment, whether through a root canal or extraction, can save you from future complications.

Frequently Asked Questions (FAQs)
Can a dead tooth heal on its own?
No, a dead tooth cannot heal by itself. Once the blood supply is lost, the tooth will not regenerate. Treatment, such as a root canal or extraction, is necessary to prevent further complications like infection or decay.
Does a dead tooth always hurt?
Not always. Some dead teeth cause no pain, especially if the nerve inside has completely died. However, if bacteria infect the surrounding tissue, pain and swelling may develop.
Can a dead tooth cause health problems?
Yes, a dead tooth can lead to serious infections, affecting nearby teeth and even spreading to the bloodstream. This can cause health complications beyond the mouth.
Will a dead tooth eventually fall out?
Yes, but it can take months or years to fall out. Waiting for it to happen naturally is not recommended, as it may cause bone loss and infection.
How can I prevent a tooth from dying?
Good oral hygiene, regular dental check-ups, and avoiding injuries (by using a mouthguard during sports) can help prevent tooth death. Treat cavities early to avoid deep infections.
