What is a Black Spot on a Tooth?
A black spot on your tooth is a dark mark that can show up on the surface or a little deeper inside. It may be caused by something as simple as a stain from food or drinks, or it could signal early decay that needs attention. While some spots are harmless, others can develop into cavities or affect the health of your tooth if left untreated.
In this article, we’ll explain why these black spots appear, what treatment options are available and how to know when it’s time to see a dentist. Understanding this can help you take better care of your teeth and keep your smile healthy.
Common Causes of Black Spots on Teeth
At Rivers Bend Family Dental, we see dark spots caused by a variety of factors, including:
- Tooth Decay
One of the most common reasons for a black spot is tooth decay. When plaque and bacteria build up on your teeth, they can gradually break down the enamel. This process may start as a small dark spot that, if untreated, can grow into a cavity. Early detection and treatment can prevent more extensive damage.
- Surface Stains
Not all black spots on a tooth signal decay. Foods and drinks such as coffee, tea, red wine and dark spices can leave stains on the enamel over time. Smoking and chewing tobacco can also contribute to discoloration. These stains are usually cosmetic and can often be addressed with professional cleaning.
- Dental Trauma
A tooth that has experienced a knock, chip or crack can sometimes darken over time. Trauma may cause the blood supply inside the tooth to change, leading to a black or greyish spot. Even if the tooth doesn’t hurt, it’s important to have it examined to prevent future complications.
- Tartar Buildup
Tartar, or hardened plaque, can appear as black spots near the gum line. Once plaque hardens into tartar, it can’t be removed with regular brushing or flossing. Professional cleaning at your dentist’s office is the safest way to remove it and protect your teeth from decay.
- Other Conditions
Certain medications, excessive fluoride exposure or developmental enamel defects can also cause dark spots. While less common, these factors can affect the appearance of your teeth and sometimes indicate a need for professional evaluation.
How to Tell If a Black Spot is a Stain or a Cavity?
Sometimes, a dark mark on a tooth can make you question if it’s simply a stain or something more serious. Although a dental checkup is the only way to be certain, a few signs can give you an idea:
Surface Stains
Stains are usually limited to the outer layer of the tooth, called the enamel. They often appear as thin, dark marks or patches that don’t change in size over time. Stains rarely cause pain or sensitivity and may fade slightly with professional cleaning or whitening treatments.
Cavities
Cavities, on the other hand, are areas where the tooth structure is breaking down. A dark spot that is rough, sticky or spreading could be a sign of decay. You might also notice sensitivity to hot, cold or sweet foods, or a mild ache that comes and goes. Left untreated, a cavity can grow larger and eventually lead to discomfort or infection.
Treatment Options for Black Spots on Teeth
Black spots on teeth can have different causes, and the treatment will depend on whether it’s a harmless stain or a developing cavity. Here are some common treatment options:
- Professional Dental Cleaning
For stains caused by food, drinks or tobacco, a professional cleaning is often the first step. Your dentist or hygienist will remove plaque and tartar that brushing and flossing can’t reach, which can help restore the tooth’s natural color. Regular cleanings also prevent further buildup that could lead to decay.
- Fillings
When a black spot is caused by a cavity, the decayed area needs to be removed and restored. Your dentist will carefully remove the decayed portion and fill it with a tooth-colored material to restore the tooth’s structure and function.
- Crowns or Veneers
In cases where the dark spot is large or the tooth has suffered significant damage, a crown or veneer may be recommended. Crowns cover the entire tooth to protect it from further decay, while veneers are thin coverings that improve the tooth’s appearance.
- Teeth Whitening
For patients whose dark spots are purely cosmetic, professional whitening treatments can help brighten teeth. Unlike over-the-counter products, professional whitening is customized to your teeth and carried out under your dentist’s supervision, making it safer and more effective than over-the-counter options.
When to Worry?
You should consider seeing a dentist right away if you notice any of the following:
- The black spot is growing or spreading.
- The tooth may be sore or sensitive when you enjoy hot, cold or sweet treats.
- There is pain, throbbing or discomfort in the tooth.
- The surface of the tooth feels rough, sticky or uneven.
- Persistent staining that doesn’t improve with brushing or professional cleaning.
How to Prevent Black Spots on Teeth?
At our Ramsey dental practice, we usually recommend these tips to our patients to prevent black spots on teeth:
- Brush your teeth at least twice a day using fluoride toothpaste to keep enamel strong and resistant to decay.
- Floss daily to remove plaque and food particles from between your teeth where a brush can’t reach.
- Limit foods and drinks that are prone to staining, such as coffee, tea, red wine and dark sauces.
- Avoid smoking or using tobacco products, which can contribute to dark spots and other oral health issues.
- Schedule regular dental checkups and professional cleanings so your dentist can catch any early signs of stains or decay.
- Consider using a mouthwash recommended by your dentist to help reduce plaque buildup and maintain a healthy mouth.

FAQs
Not always. Sometimes they’re just surface stains from coffee, tea or certain foods. But if a spot feels rough, sticky or sensitive, it’s worth getting checked.

It varies. Some spots stay harmless for months, while others can progress in weeks. That’s why regular dental checkups are so important.
Yes, but only if the spot isn’t caused by decay. A dentist can make sure whitening won’t harm the tooth and can give the best results safely.
If the spot grows, hurts or makes your tooth sensitive, don’t wait. Early treatment is easier and quicker and helps avoid bigger problems.
A tiny black spot with no pain is often just a stain, but it could be early decay. It’s best to have a dentist check it to be safe.
