It can be scary to hear that you have a “dead tooth.” However, it is more common than you may think. If you’ve been told one of your teeth has died, you may wonder what it means and whether anything can be done to save it. Fortunately, in many cases, a dead tooth can be treated. Here’s everything you need to know. 

What Is a Dead Tooth?

A tooth is considered “dead” when the pulp inside, which contains nerves and blood vessels, is damaged beyond repair, usually due to decay or trauma. Without fresh blood flow, the tooth loses its vitality and may eventually change color, becoming gray, yellow, or even black. 

Common signs of a dead tooth include:

• Discoloration from the breakdown of blood cells within the pulp and a lack of oxygen
• Sensitivity or pain when biting or chewing, or because of temperature changes
• Bad taste or odor because of tissue breaking down
• Swelling or an abscess as a result of a collection of pus in the gums or jawbone

A dead tooth can die due to trauma or injury to the mouth, such as getting hit in the mouth by a ball, or as a result of poor dental hygiene and cavities. It can also die because of repeated dental procedures or severe grinding (bruxism). A tooth can die within a few days or over several months or years. 

Will a Dead Tooth Always Hurt?

A dead tooth may not always hurt. While some cause sharp pain or lingering sensitivity, others may be completely painless, especially if the nerve has already died. However, just because you don’t have any symptoms doesn’t mean the dead tooth can’t harbor dangerous bacteria.

Can a Dead Tooth Be Saved?

In many cases, a dead tooth can be saved, at least structurally, with proper treatment. The key is to address the problem early before it causes further complications. 

1. Root Canal Therapy 

A root canal is the most common way to save a dead tooth. During a root canal, a dentist or endodontist removes the dead pulp, cleans out the infection, and seals the tooth. Often, a crown is placed afterwards to restore strength and match the color of the surrounding teeth. 

Benefits:

• Retains your natural tooth
• Eliminates pain and infection 
• Prevents the shifting of nearby teeth 
• Helps restore your smile

2. Tooth Extraction (If Necessary)

If the tooth is too damaged to save, such as when the structure is severely decayed or the infection has spread, extraction may be the best option. After extraction, you can replace the tooth with a dental implant, bridges, or partial dentures can fill the gap. 

Benefits: 

• Removes the source of infection. 
• Prevents complications like bone loss or spread of bacteria. 
• Alleviates the pain caused by severe decay or infection. 

What Happens If a Dead Tooth Is Left Untreated?

Ignoring a dead tooth can lead to serious consequences, such as:

Infection and Abscess — Bacteria can multiply within the dead tooth and lead to severe infection or a pus-filled pocket (abscess) at the root. 

Jaw Bone Deterioration — Bone loss around the dead tooth can make it harder for your jaw to support other teeth or implants. 

Spread of Bacteria — In rare cases, dental infection can spread through the bloodstream and cause serious health problems. 

Tooth Loss — A dead tooth can become brittle and susceptible to breaking, potentially leading to tooth extraction. 

That’s why early diagnosis and treatment are essential.

How to Prevent a Tooth from Dying

While not all causes of a dead tooth can be avoided (such as trauma), good oral hygiene and routine dental visits can reduce your risk. Here’s how: 

• Brush twice daily and floss once daily 
• Wear a mouthguard during sports to protect your teeth
• Treat cavities and dental trauma promptly
• Drink plenty of water, maintain a healthy diet, and limit sugary foods 
• Avoid biting hard objects or using your teeth as tools to open things
• Don’t ignore signs of tooth pain or discoloration 

Protect Your Teeth from Decay 

When a tooth dies, it doesn’t always have to be removed. Thanks to modern dentistry, root canal therapy often offers a safe and effective way to save your natural tooth. However, prompt treatment is critical; the longer you wait, the fewer options you may have. 

If you suspect you have a dead or dying tooth, consult your dentist or an endodontist as soon as possible. Saving your smile might be easier than you think.
