Why Black Spots Appear on Teeth & How to Remove Them

Seeing a dark spot on your tooth is not a fun experience. If you have black dots on teeth, these marks may indicate anything from harmless staining to early signs of decay. The dark spots that occur on teeth can develop from poor brushing habits, smoking cigarettes, or coffee consumption. Oftentimes, a black spot on a tooth can dull your smile and affect your confidence. Fortunately, most causes of dark spots on teeth are treatable and/or preventable. Understanding what causes black marks on teeth and what you can do to remove them helps put you on the path to a bright, radiant, healthy smile.

Common Causes of Black Spots on Teeth

Black tartar originates from common yellow plaque. If the plaque is not removed over time, it can polymerize and appear green, brown, or even black due to certain factors. These factors can affect the visual appearance and, more importantly, create significant risks to dental health.

Here are the causes for black spots on teeth:

Tooth Decay

Both mineralized tooth decay and cavities that have progressed may present as black spots. A mineralized tooth decay will produce black spots in the grooves of the chewing surface of the tooth. Advanced cavities may also have black spots around the base and holes on the enamel surface, which can contribute to the retention of food particles.

Plaque

If teeth do not get cleaned well after eating, plaque can harden around the teeth and under the gumline and become brown or black over time.

Smoking and Colored Foods

Again, plaque on the teeth is quite adept at absorbing pigments from foods and other products that are consumed. Thus, those who smoke or consume many colored foods are more likely to have discolored teeth.

Weak Enamel

Weak or deficient enamel can lead to black stains.

Excessive Fluoride or Antibiotics

Taking too much fluoride or antibiotics over a long period can also produce black or mottled stains on teeth.

In general, the causes of black tartar and black spots on teeth are the result of daily behaviors that fall short of recommended practices.

Why Remove Black Stains on Teeth?

Black stains on teeth are severe forms of tartar. If not cleaned or removed early, they can cause:

• Periodontitis and Gingivitis: Bacteria in black tartar can gradually destroy enamel and attack the gums, leading to gum inflammation and periodontal disease.
• Bad Breath: Black tartar indicates a large accumulation of bacteria, some of which produce odors, causing bad breath and affecting confidence in social interactions.
• Gum Recession, Bone Loss, and Tooth Loss: Black tartar breaks the connections between the tooth and the gum, easily leading to gum recession. It also attacks the jawbone, causing bone loss, and if left untreated for a long time, it can result in tooth loss.

How to Remove Black Spots on Teeth?

Removing a black spot on teeth depends on the cause, whether it’s a simple surface stain or a cavity forming underneath the enamel. Fortunately, modern dentistry offers several safe, effective solutions to eliminate black marks on teeth and restore a healthy, white smile.

Professional Cleaning and Polishing

When black stains on teeth result from tartar buildup or surface discoloration, professional dental cleaning (also known as prophylaxis) is the most reliable treatment.

Procedure:

During a cleaning session, your dentist or hygienist uses ultrasonic scalers, vibrating tools that break down and remove hardened plaque and tartar deposits. Once the tartar is cleared, the dentist uses a polishing paste and a rotating brush to smooth the enamel surface, erasing surface stains and making the teeth shine.

Why it’s Effective:

• Removes black on teeth caused by plaque and tartar that brushing can’t eliminate.
• Smooths enamel to prevent future stain accumulation.
• Enhances gum health by removing bacterial buildup.

When to Choose this Option:

If your black dots on teeth are mainly near the gumline or you haven’t had a dental cleaning in over six months, professional polishing is the first step to a spotless smile.

Teeth Whitening Treatments

For stubborn dark spots on teeth that don’t respond to cleaning, whitening treatments can help. These treatments target deep-seated stains in the enamel that result from coffee, tea, wine, or tobacco.

Professional Whitening (In-Office)

Dentists apply a high-concentration hydrogen or carbamide peroxide gel and may activate it with a special LED or laser light. The session usually lasts 30–60 minutes and can instantly brighten teeth by several shades.

At-Home Whitening Kits

These include custom whitening trays or whitening pens with milder gel concentrations. They gradually reduce black stains on teeth over several days or weeks.

Benefits:

• Effective for extrinsic stains.
• Improves the color uniformity of your smile.
• Safe and dentist-approved options minimize enamel sensitivity.

Pro Tip:

Avoid overusing whitening products without guidance; excessive application can cause tooth sensitivity or uneven results.

Filling or Restoration

When a black spot on a tooth is caused by decay or a cavity, a professional filling or restoration is necessary. These dark spots often indicate that bacteria have eroded the enamel, exposing the dentin layer underneath.

Procedure:

• The dentist numbs the area to ensure comfort.
• The decayed portion is carefully drilled out to remove infected material.
• A tooth-colored composite resin is applied in layers to rebuild the tooth’s structure.

The filling is hardened using a special curing light and polished for a natural finish.

Benefits:

• Stops the spread of decay.
• Restores tooth shape, strength, and aesthetics.
• Prevents further discoloration or pain.

When necessary:

If your black dot on a tooth feels rough, sensitive, or changes size over time, it’s likely decay rather than a surface stain. Prompt treatment prevents root canals or tooth loss later.

Replacement of Metal Fillings

Old silver (amalgam) fillings can oxidize and leak, creating black marks on teeth or grayish stains around the restoration. Replacing them with modern materials not only brightens your smile but also strengthens your teeth.

Procedure:

• The dentist removes the old amalgam filling safely.
• The area is cleaned and prepped for a new filling.
• A composite resin or ceramic material, matched to your natural tooth shade, is applied.
• The restoration is shaped, hardened, and polished for a seamless blend.

Benefits:

• Eliminates unsightly dark spots on teeth near old fillings.
• Creates a natural, stain-resistant finish.
• Restores full tooth function with improved appearance.

Why it matters:

Replacing old fillings can prevent further staining or corrosion and enhance overall dental aesthetics, especially when front teeth are involved.

Home Remedies to Reduce Black Dots on Teeth

Here are the natural remedies that can help gently remove black dots on teeth and prevent new stains from forming, while keeping your enamel healthy and strong.

Eliminating Black Stains with Lemon

Lemon has a high concentration of citric acid. When citric acid meets the enamel surface, it softens the plaque and creates less difficulty in removing tartar.

Instructions for Use

• Take a fresh lemon and squeeze it.
• On a toothbrush, apply the lemon juice to your teeth. Brush softly to ensure the solution reaches all surfaces of the teeth, and brush vertically, so the solution will cover the surface and the gaps between teeth.
• At last, rinse your mouth with water.

Caution: Citric acid functions similarly to natural enamel, so do not exceed weekly use.

Eliminating Plaque with Salt

Salt not only cleans but also aids in eliminating bacteria in the mouth and may contribute to preventing many dental diseases.

Instructions for Use

Method 1: Get fine salt, then sprinkle it on your toothbrush and brush your teeth.

Method 2: Combine salt with a little lemon juice, then brush your teeth with the combination for a few minutes to clean your teeth.

You may want to consider doing this daily to maximize the effectiveness of cleaning plaque on your teeth. You will see results after a few times; your teeth will be cleaner and brighter.

Using Baking Soda to Remove Black Stains

Baking soda has a variety of uses, from cleaning plaque to whitening teeth. It can break down and soften tartar, as well as create an alkaline substance that prevents harmful bacteria from growing.

How to Use

Method 1: Take your toothbrush and dip it in the baking soda, then brush your teeth just as you would with toothpaste for two minutes.

Method 2: Combine a bit of baking soda with lemon juice to create a paste, and then brush your teeth as normal.

After a few minutes, you will notice a difference with clearer and whiter teeth.

Note: Similar to lemon juice, if you use baking soda too often, it can be harmful to your enamel, so please only do this once a week.

Prevention Tips for a Spot-Free Smile

• Brush twice daily with fluoride toothpaste.
• Floss once a day to prevent plaque accumulation.
• Limit dark beverages like coffee and red wine.
• Quit smoking to avoid persistent black stains on teeth.
• Schedule professional cleanings every six months.

Consistent oral care habits can prevent new black marks on teeth and maintain lasting whiteness.
