Types of brown stains on teeth

Brown marks on teeth might be obvious, but others might be barely detectable. They come in a variety of shades from nearly yellow to dark brown. Some brown spots appear as dots, while others appear as lines.

What causes brown stains on teeth?

Brown stains between teeth may be from a variety of factors such as nicotine and tobacco, dark-coloured foods and beverages, medications, trauma, celiac disease, enamel hypoplasia, or natural ageing.

Nicotine & tobacco

Tobacco is a frequent cause of brown teeth. Nicotine may be present in a variety of tobacco products, including:

  • Cigarettes
  • Cigars
  • Pipe tobacco
  • Chewing tobacco
  • Vaping

These contain particles that may adhere to the tooth enamel's small pores. The particles accumulate over time and may stain the teeth. The stains tend to darken and become more difficult to remove with time.

Foods and beverages with a dark colour

What you eat and drink may cause tooth discolouration, including brown, grey, and yellow stains. This is due to the presence of chromogen molecules in many dark-coloured foods and beverages.

In addition to that, foods like wine, coffee, tea, soda, and dark chocolate contain tannic acid, which makes the chromogens more sticky and speeds up the formation of the brown stuff on teeth.

Coloured substances may leave spots and marks on the enamel. These stains might become permanent over time, especially if the person has poor oral care. Artificially coloured foods and beverages may also cause considerable discolouration of the teeth.

Here’s a list of foods and drinks that can cause your teeth to turn brown over time:

Teeth turning brown can also be caused by antibiotics like tetracycline and doxycycline. This is particularly likely to happen in youngsters who are still growing their teeth. It may also be passed on to children if their mother took them while pregnant.

Brown stains on teeth may also be caused by the medicine glibenclamide (Glynase), which is used to treat permanent neonatal diabetes mellitus.

Antihistamines, high blood pressure drugs, and antipsychotic medications are all known to stain teeth. It goes without saying that you should never stop taking a prescription medication just because it is staining your teeth.

Root canal

A root canal is required when the pulp of one of your teeth dies. This may cause a tooth to become brown and remain brown. It's due to the darkening of the dead root, which has permeated the tooth.


A tooth's nerve may be damaged by trauma to the mouth. The tooth may develop brown spots or become entirely brown as a consequence.

If your traumatised tooth is still alive and well, it will most likely return to its original colour between two and six months after the damage. Teeth bleaching can be utilised to restore your teeth's whiteness if they do not return to their normal colour.

Enamel hypoplasia

Teeth with less enamel than necessary may be caused by genetic or environmental reasons. Enamel hypoplasia is the medical term for this condition.

Enamel hypoplasia may be caused by a variety of factors, including:

  • Deficiencies in vitamins
  • Illness in the mother during pregnancy
  • Exposure to toxins

Enamel hypoplasia may damage one or more teeth, causing brown or yellow stains to appear.


Plaque is formed when bacteria in the mouth mix with food and saliva to form a sticky, transparent coating. When plaque isn't removed regularly, it may harden and develop into tartar. Tartar may be yellow or brown in appearance and occurs at the gum line. Brown plaque on teeth may actually be tartar that appears brown in colour.

Brushing our teeth with toothpaste and flossing is usually enough to keep plaque levels under control. However, after tartar has formed, it can only be removed by a dentist.

Apart from poor oral hygiene, the following factors might cause the development of tartar:

  • Use of nicotine (smoking, chewing tobacco, cigars)
  • Hormonal changes, such as those that occur during pregnancy, puberty, and menopause
  • Medicines that reduce the levels of saliva in the mouth, like nerve blockers or management medications for AIDS
  • Diabetes

Tooth decay

The sugars you consume provide food for plaque and tartar bacteria. They also produce acids that erode enamel. Plaque and tartar have a thick, filmy structure that causes acids to attach to the teeth for lengthy periods of time.

The yellow layers of the tooth underneath become increasingly evident when the acids degrade the enamel. The teeth may seem yellowish-brown as a result. If the tooth decay is severe enough, the acids may penetrate the tooth and produce a hole or cavity.

Even little fractures and breaks in the teeth may allow germs to enter and cause decay. When bacteria pass through the cracks of dental fillings or crowns, many patients get brown spots of decay.

Previously completed dental work

Metal, silver, or white fillings that have deteriorated over time may discolour teeth. Surface stains on white fillings might cause the tooth to appear brown.

Celiac disease

Celiac disease may cause enamel issues in the teeth. Brown stains on the teeth are not uncommon in celiac disease patients.


Fluorosis is a dental issue that alters the appearance of the teeth. Excessive exposure to fluoride within the first eight years of life triggers it, when fluorosis-affected people's teeth may seem slightly stained once they come in.

However, if fluorosis is severe, the tooth enamel fractures and brown spots appear. Severe fluorosis is uncommon.

Because of the hypomineralisation of enamel, teeth with fluorosis might be compromised, making them potentially weaker than teeth without fluorosis. This may lead to tooth decay and make teeth turn brown in the long run.

Natural ageing

It's natural for people's teeth to darken or to develop brown spots as they become older. This may be triggered by several causes that accumulate over time, including:

  • Surface staining from foods and drinks high in chromogens and tannic acid.
  • The enamel is thinning and the dentin becomes visible. It's the layer of the tooth underneath the enamel. When the protective layer (enamel) on the dentin wears away, the teeth become sensitive to hot and cold because the nerves and cells within the tooth are activated. The dentin has a darker colour, which can be another reason for brown teeth.

Early symptoms of brown teeth

Look for the following signs and symptoms:

  • Brown spots on teeth near gums
  • Brown stains between teeth
  • Brown lines on teeth
  • Brown spot on front tooth
  • Brown plaque on teeth

Brown spots on teeth may be an early symptom of dental cavities, which must be treated by a dentist. Symptoms such as tooth discomfort, sensitivity, or bad breath may accompany them.

Gingivitis may develop if tooth decay becomes severe. Consult a dentist if brown spots are accompanied by bleeding or painful gums regularly.

The teeth of people with enamel hypoplasia may have a rough surface or brown spots.

How to prevent brown stains on teeth

Maintaining good oral hygiene can help keep your teeth white, brilliant, and free of brown stains. After eating or drinking staining foods or beverages, clean your teeth with good toothpaste.

Here are some suggestions for preventing brown spots on teeth:

Quit smoking

Smoking is among the most common causes of brown stains on teeth, and nothing will make your smile yellow faster than this bad habit. There are hundreds of reasons to stop smoking, and one of them is to prevent your teeth from turning brown.

After consuming certain foods and beverages, rinse your mouth or brush your teeth

Unfortunately, a variety of foods and drinks have the potential to discolour our teeth. These include wine (both white and red), tea and coffee, soda, dark fruits, beets, soy sauce, and many more.

If a meal can stain your hands or clothing, it's likely to stain your teeth as well! Therefore, if you eat foods that stain often, you should consider washing your mouth with water or mouthwash afterwards or brushing your teeth to avoid brown spots.

Cleanings and oral exams should be done routinely

Teeth cleaning on a regular basis may help you maintain a white smile. A teeth cleaning maintains a healthy mouth and removes plaque, which may pick up surface stains and give your teeth a whiter appearance. It’s recommended to get your teeth cleaned once or twice a year.

So, how do I get rid of brown spots on teeth?

First and foremost, unless your dentist advises differently, you should see your dentist every six months for a cleaning that may involve scaling if needed. Scaling your teeth entails eliminating tartar build-up and cleaning the surfaces of your teeth using specialised equipment.

Your teeth may be considerably whiter after a professional cleaning — depending on the state they were in beforehand. However, if you want more significant results, you'll need to consider your teeth whitening possibilities.

Professional in-clinic teeth whitening

In-clinic whitening, which is usually done by professionals under the instruction of a dentist, is a favourite option among many for eliminating brown stains from teeth.

Before teeth whitening, a patient's teeth and gums are carefully cleaned, followed by the application of a bleaching agent. At the completion of the treatment, UV light or an argon laser may be used.

You can consider this a very safe method since the process is done under the professional guidance of dentists. This method is more expensive, but it enables you to quickly remove even the most persistent brown spots.

Home whitening products

Surface stains may be possible to remove with at-home whitening procedures. However, whitening procedures may not work for all tooth discolourations.

You can buy teeth-whitening pens, strips, bleaching trays, and other home-whitening LED kits to brighten your smile. It's important to follow the directions on these products in order to get the most out of them.

To have the optimum benefits, they should be used on a regular basis (meaning once per year or following packaging instructions). However, don't use them too often or continuously since they might wear down your tooth enamel.

Home remedies
