A Complete Guide to Spots on Your Teeth

Discoloration, staining, and spots on your teeth can be caused by a wide range of factors, from diet and lifestyle habits to underlying dental health issues like enamel erosion or early decay. Because it’s not always easy to tell the difference between a harmless stain or spot and a sign of something more serious, routine oral care is crucial. Regular cleanings, professional evaluations, and good at-home habits not only improve the appearance of your teeth but also help catch and address potential problems early.

Is the spot on my tooth a cavity or a stain?

A spot on your tooth could be something as simple as a surface stain—or it could be the early sign of a cavity forming beneath the enamel. Because they can look similar at first, it’s important to understand the difference between the two.

A stain is a discoloration of a tooth–or several teeth–caused by some external factor and can often be removed or improved with treatment or better oral hygiene. Stains, spots, or discolorations typically don’t cause pain or sensitivity. 

A cavity is tooth decay that affects a targeted area of a tooth and damages the tooth’s internal structure. Untreated cavities are likely to cause pain and sensitivity and require professional restorative treatment.

The only way to know for sure what’s causing the spot is to visit a dentist, who can examine your teeth and determine whether it’s cosmetic or something that needs treatment.

Top 10 Things That Can Cause Stains and Spots on Your Teeth

Stains and spots on your teeth can come from a wide range of sources and factors, from everyday habits to underlying dental or health issues. While some discoloration is superficial and cosmetic, other marks may signal deeper problems that need professional attention.

  1. Poor oral hygiene. A buildup of plaque and tartar can make your teeth look more yellow than white.
  2. Tobacco use, including smoking and smokeless tobacco. Nicotine turns yellow when exposed to air. Porous tooth enamel traps the nicotine and turns your teeth yellow.
  3. Acidic or dark-colored foods and beverages, especially coffee, tea, wine, and soda
  4. Medical conditions, such as eating disorders, liver disease, celiac disease, calcium deficiency, and metabolic diseases.
  5. Medications, particularly antibiotics like tetracycline or doxycycline taken before age 7, certain antihistamines and medications for high blood pressure, and certain antidepressants or antipsychotic drugs.
  6. Fluorosis, which occurs when excessive fluoride intake during tooth development causes changes in the enamel, leading to white spots, streaks, or even brown discoloration on the teeth.
  7. Genetics, which can have an impact on the brightness and/or thickness of your enamel. Enamel hypoplasia is a genetic condition that affects tooth formation and can cause tooth enamel to be too thin or even completely absent.
  8. Aging. As you age, the enamel on your teeth naturally thins, exposing more of the yellowish dentin underneath and making teeth more prone to discoloration and staining.
  9. Some dental treatments. Root canals or dental fillings with silver amalgam can make your teeth appear gray or discolored. Although a highly effective treatment for preventing the progression of cavities, silver diamine fluoride (SDF) can cause black staining when it comes into contact with decayed areas of the affected tooth. (Healthy tooth enamel is not stained.)
  10. Vitamin and mineral supplements or deficiencies. Sometimes vitamins and mineral supplements can interact with the tooth enamel and oral environment in a way that causes tooth staining and discoloration. Chewable tables introduce acids that erode enamel, while supplements like iron can leave behind deposit pigments. Deficiencies in other vitamins and minerals can also weaken enamel, increasing the risk of discoloration or decay.

Types of Tooth Stains

Tooth stains and spots develop when pigments from food, drinks, tobacco, or other sources build up on the enamel or penetrate deeper into the tooth structure. Extrinsic stains, which affect the surface of the enamel, are often easier to treat with professional cleanings or whitening treatments. Intrinsic stains, which occur inside the tooth, and age-related discoloration, which results from enamel thinning and dentin changes, typically require more advanced treatments like bonding, veneers, or restorative care. Understanding the type of staining is important because it helps your dentist determine the best course of action to not only improve your smile’s appearance but also protect your long-term oral health.

Here are 3 types of tooth stains:

Extrinsic, or external, stains

In addition to affecting the tooth’s outer layer (the enamel), extrinsic or external stains are generally caused by external factors, like foods or drinks that you consume and smoking or tobacco use. As your teeth come into contact with these substances, the enamel begins to absorb some of the colors, causing a stain. However, since they don’t reach below the enamel into the dentin, external stains are usually easier to remove than other types. They may even be preventable by simply watching what you eat and drink.

Intrinsic, or internal, stains

Conversely, internal–or intrinsic–stains occur within the tooth structure and are typically the result of trauma, tooth decay, or certain medications. Although they are affecting the internal structure of the tooth, intrinsic stains may appear as dark spots or discoloration.

Age-related stains

Age-related staining occurs as the result of thinning enamel and darkening dentin. As we age, the dentin within our teeth turns a darker shade of yellow-brown that becomes more visible as the outer enamel becomes thinner, making your teeth themselves appear darker.

Types of Spots on Your Teeth–And What They Mean

Spots on teeth can appear for many reasons, and their cause often depends on where they’re located and which teeth are affected. Because spots can range from harmless stains to signs of more serious issues like decay or enamel erosion, it’s important to visit a dentist for an accurate diagnosis and appropriate treatment.

White spots

White spots on your teeth could be an indication of decalcification or demineralization, a common cosmetic dental problem in which calcium, phosphate, and other essential minerals are removed from the enamel of the teeth, creating white or chalky spots. White spots as a sign of weakened enamel or tooth decay can also occur in response to eating too many acidic foods, a diet high in sugar, or acid reflux.

White spots or streaks can also develop in response to too much fluoride, a condition called fluorosis. While fluoride in the right quantities is highly beneficial to protecting teeth from cavities and decay, high levels of it–especially during childhood–can result in fluorosis. 

White spots on your teeth after removing braces could be the result of plaque buildup underneath or around the brackets, which cause demineralization of the tooth.

Brown spots

Brown spots on your teeth are typically a sign of poor oral hygiene, diet, or lifestyle habits, but they can also be a warning sign of broader health concerns, like celiac disease. Brown spots can be caused by tobacco use or by frequent consumption of dark-colored beverages like coffee or red wine. If you have poor oral hygiene, plaque and tartar buildup can attract more bacteria, food debris, and staining particles, making your teeth look even more brown and dull.

Brown pits in your teeth are likely an indication of untreated tooth decay and cavities.

Yellow spots

Yellow spots are generally surface stains caused by foods and beverages. Yellow spots could also be caused by natural age-related yellowing of the enamel, or as the result of deficiencies in vitamins like calcium, A, or B Complex.

Gray or blue spots

Gray or blue spots on your teeth are most likely intrinsic stains caused by trauma to the tooth or by certain medications. Gray discoloration can also mean that the nerve inside the tooth has died.

Black spots

There are a variety of factors that can cause black spots on your teeth, from poor oral hygiene and tooth decay to tobacco use. Stains from dark-colored foods and beverages can also turn into black spots over time.

Painful spots

A spot on your tooth may become painful if it is caused by underlying issues like tooth decay, enamel erosion, or infection that exposes the sensitive inner layers of the tooth. A painful spot could be an indication of a cavity, a tooth abscess, a cracked tooth, or just general tooth sensitivity. 

Spots on front teeth 

Spots on front teeth are most commonly linked to problems with the enamel, inadequate oral hygiene, or overexposure to fluoride. White spots often indicate demineralization, a process where the enamel weakens and loses minerals, while dark spots are usually caused by plaque accumulation, tartar, or developing tooth decay

Spots on back teeth

Spots on back teeth are often caused by plaque buildup, deep grooves and pits that trap food particles, and early stages of tooth decay. Because back teeth are harder to reach and clean thoroughly, they are more prone to developing cavities, staining, and discoloration over time.

Spots on baby teeth

Spots on baby teeth are commonly caused by early tooth decay, enamel hypoplasia (a defect in enamel development), or excessive fluoride exposure. Baby teeth are particularly susceptible to white or brown spots due to their thinner enamel and greater vulnerability to cavities if proper oral hygiene isn’t maintained.

Treating Spots on Your Teeth

Different types of spots on your teeth may require different treatments depending on their cause, severity, and location. Superficial stains from foods, drinks, or tobacco often respond well to professional whitening, while deeper, more permanent discoloration from enamel defects, trauma, or decay may need more extensive cosmetic or restorative care. Treatments like veneers, crowns, and fillings can not only improve the appearance of teeth but also restore their strength and function when damage is involved. Choosing the right solution is essential for protecting your long-term oral health while achieving the best aesthetic results.

If your spots or stains are primarily extrinsic, they can usually be treated with professional teeth whitening, or–depending on the severity–dental bonding or veneers.

If your stains, spots, or discoloration are the result of tooth decay or tartar buildup, you need professional treatment, including professional cleaning and/or restorative procedures such as a filling or root canal.

Here are some of the most common treatments for treating spots on your teeth and the types of spots they help address:

  • Professional Teeth Whitening. Best for extrinsic (surface) stains caused by foods, drinks, or smoking.
  • Dental Veneers. Ideal for intrinsic stains, enamel defects, or discoloration that does not respond to whitening.
  • Dental Crowns. Used for teeth with extensive discoloration due to decay, trauma, or after large restorations.
  • Tooth Restorations (Fillings). Appropriate for spots caused by cavities, early decay, or damaged enamel.
