Have you noticed a blackish colour on your teeth, a dark spot on one tooth or black stains near your gums?
Black discoloration on teeth can have several causes. Sometimes it is simply an external stain that can be removed with professional cleaning. In other situations, a dark or black area may indicate tooth decay, a damaged tooth or another dental problem that needs treatment.
The appearance alone cannot always tell you what is causing the discoloration.
If you have noticed black spots on your teeth, it is therefore better to have the area examined by a dentist rather than trying to remove it yourself.
At Skyline Dental – Multispeciality & Aesthetic Centre in Nallurhalli, Whitefield, Bengaluru, we evaluate the tooth and surrounding gums to determine the cause of discoloration before recommending treatment.
What Causes Black or Blackish Teeth?
There isn’t one single reason why a tooth may appear black.
Common causes include:
- Tooth decay
- External stains
- Tartar or calculus
- Food and plaque accumulation
- Certain drinks and tobacco products
- Trauma to a tooth
- A previously treated or non-vital tooth
- Some medications or dental materials
- Natural variations in tooth colour
The location, texture and appearance of the discoloration can provide useful clues, but a proper dental examination is often needed for an accurate diagnosis.
Black Spots on Teeth Can Be Caused by Tooth Decay
One of the causes that should not be overlooked is dental decay.
Early tooth decay may appear as a white, brown or dark area. As decay progresses and more tooth structure is destroyed, the affected area can become darker.
A tooth affected by decay may also develop:
- Sensitivity to cold or sweets
- Food getting stuck
- Pain while chewing
- A visible hole or cavity
- Toothache
- Bad taste or unpleasant smell
However, decay does not always cause pain in its early stages.
This is why a black spot on a tooth should not automatically be assumed to be a harmless stain.
Can Tartar Make Teeth Look Black?
Yes.
Tartar, also known as dental calculus, is hardened plaque that cannot be completely removed with normal brushing.
It commonly accumulates along the gumline and can appear yellow, brown or dark in colour. In some people, deposits can become very dark and may be described as black tartar.
Dark deposits may be more noticeable in people who use tobacco or have significant plaque accumulation.
Professional dental cleaning can remove hardened deposits that cannot be effectively removed at home.
However, if the dark area is actually part of the tooth rather than a surface deposit, cleaning alone will not correct the problem.
Black Stains on Teeth May Be External Stains
Not every dark mark means that the tooth is decayed.
Certain substances can stain the outer surface of teeth over time.
Common contributors include:
- Tea
- Coffee
- Tobacco
- Smoking
- Certain foods and beverages
- Poor plaque control
Surface stains may be more noticeable around the gumline or between teeth.
If the discoloration is superficial, professional cleaning and polishing may significantly improve the appearance.
Why Is One Tooth Turning Black?
A single tooth that becomes noticeably darker than the surrounding teeth deserves particular attention.
A tooth can become grey, brown or black following trauma or damage to the pulp inside the tooth.
This can happen even if the original injury occurred months or years earlier.
A darkened tooth may therefore require more than cosmetic cleaning.
Your dentist may examine the tooth and, when appropriate, recommend an X-ray and other tests to determine whether the pulp is healthy.
Can a Dead Tooth Turn Black?
A tooth that has lost its normal vitality can sometimes become darker or greyish.
This can occur following:
- Dental trauma
- Deep decay
- Previous dental procedures
- Infection or damage to the pulp
However, tooth colour alone cannot confirm whether a tooth is non-vital.
A dentist needs to evaluate the tooth clinically and determine whether further investigation or treatment is required.
Depending on the diagnosis, treatment could range from monitoring to root canal treatment or another appropriate restoration.
Black Teeth After an Injury
Have you noticed that a tooth became darker after being hit or injured?
Dental trauma can sometimes affect the pulp inside a tooth.
The colour change may not occur immediately and can become noticeable later.
If a tooth has changed colour after an injury, particularly if you also have pain, swelling or tenderness, arrange a dental examination.
Even if the tooth does not hurt, a post-traumatic colour change is worth discussing with a dentist.
Can Black Teeth Be Cleaned?
It depends on what is causing the discoloration.
If It Is Surface Staining
Professional teeth cleaning and polishing may remove external stains.
If It Is Tartar
A professional scaling procedure can remove hardened calculus.
If It Is Tooth Decay
Cleaning cannot remove decay.
The decayed portion of the tooth needs to be assessed and treated appropriately. Depending on the extent of damage, treatment may involve a filling, root canal treatment or another restoration.
If the Tooth Has Changed Colour Internally
Internal discoloration may require a different approach.
The dentist first needs to determine why the tooth has changed colour before discussing cosmetic or restorative treatment.
How Is the Cause of Black Teeth Diagnosed?
Your dentist may examine:
- The colour and location of the dark area
- Whether the surface is hard or soft
- The condition of the gums
- Plaque and tartar accumulation
- Signs of tooth decay
- Previous dental treatment
- History of trauma
- Symptoms such as pain or sensitivity
An X-ray may be recommended when the dentist suspects decay, infection or a problem that cannot be assessed by visual examination alone.
The important point is that black discoloration should be diagnosed before treatment is chosen.
Can You Remove Black Stains at Home?
It is tempting to try to scrape or scrub a black mark from a tooth.
This is not recommended.
Using sharp objects or abrasive substances can damage the enamel or gums.
Similarly, repeatedly using strong whitening products will not treat tooth decay or remove hardened tartar.
If the discoloration does not disappear with normal brushing, professional evaluation is safer than trying to remove it yourself.
Does Teeth Whitening Remove Black Spots?
Usually, whitening is not the first treatment for a localised black spot.
Teeth whitening works primarily by lightening the colour of natural teeth. It does not treat cavities or remove hardened tartar.
If you have one dark spot or one tooth that has become significantly darker, the underlying cause should be diagnosed first.
Once any dental disease has been treated, cosmetic options can be considered where appropriate.
When Should You See a Dentist for Black Teeth?
You should consider a dental examination if:
- A tooth has suddenly become dark
- You notice a new black spot
- The discoloration is getting larger
- The tooth is painful
- You experience sensitivity
- Food repeatedly gets stuck in the area
- The tooth feels rough or develops a hole
- Your gums bleed around the area
- There is swelling
- You have a history of trauma to that tooth
Even without pain, a new or unexplained dark area deserves attention.
Black Teeth Treatment Depends on the Cause
There is no single black teeth treatment.
Your treatment depends on the diagnosis.
Professional Cleaning
Appropriate for plaque, calculus and certain external stains.
Dental Filling
May be required when decay has caused a cavity but enough healthy tooth structure remains.
Root Canal Treatment
May be required when decay or trauma has affected the pulp inside the tooth.
Crown
A significantly weakened or extensively restored tooth may require a crown to restore and protect it.
Cosmetic Treatment
Once dental disease has been ruled out or treated, cosmetic options may be considered for certain types of discoloration.
The priority should always be treating the underlying dental problem before focusing on appearance.
How Can You Prevent Dark Stains and Tooth Decay?
Good everyday oral care can reduce the risk of both tooth decay and external staining.
Brush Twice Daily
Use fluoride toothpaste and brush for approximately two minutes.
Clean Between Your Teeth
Floss or use interdental cleaning aids to remove plaque from areas a toothbrush cannot reach.
Limit Frequent Sugary Snacks
Repeated exposure to sugar increases the risk of dental decay.
Have Regular Dental Checkups
Regular examinations can identify cavities and other problems before they become more extensive.
Consider Professional Cleaning
If you develop significant tartar or staining, professional cleaning can help maintain your oral health.
Avoid Tobacco
Smoking and tobacco products can contribute to staining and increase the risk of several oral health problems.

Frequently Asked Questions
Why are my teeth turning black?
Black discoloration can be caused by surface stains, tartar, tooth decay, trauma or internal changes within a tooth. A dentist can determine the likely cause through examination.
Is a black spot on a tooth always a cavity?
No. A black spot can be caused by staining or tartar, but decay is also a possibility. The area should be examined rather than assuming what it is.
Can black tartar be removed?
Yes. Hardened tartar can generally be removed through professional dental cleaning. Attempting to scrape it off yourself can damage the gums or teeth.
Can a dead tooth turn black?
A tooth that has lost vitality can sometimes become darker or greyish. However, colour alone cannot confirm that a tooth is non-vital.
Can brushing remove black stains?
Some superficial stains may improve with good brushing, but hardened tartar and certain stains require professional cleaning.
Can black teeth be whitened?
The answer depends on the cause. Whitening does not treat cavities or remove tartar. The underlying cause should be identified before cosmetic treatment.
Is a black tooth an emergency?
Not every black tooth is an emergency, but sudden discoloration accompanied by pain, swelling, trauma or infection symptoms should be evaluated promptly.

A blackish colour on teeth can have many causes, ranging from harmless surface staining and tartar to tooth decay, trauma or changes within the tooth.
