Teeth discoloration and stains are some of the common oral problems that can happen for different reasons. It is a condition where the teeth are stained and develop a dark color. Sometimes this happens due to avoidable reasons like smoking and poor oral hygiene, and sometimes it happens due to unavoidable reasons like aging and diseases. However, these problems are preventable and can be treated with the help of a dentist. 

Different Types Of Teeth Discoloration

Teeth discoloration comes in three different categories. They are:


When stains are causing extrinsic tooth discoloration, they most likely affect the tooth’s surface, or enamel. Extrinsic stains are most frequently caused by the following: 

  • Beverages
  • Food
  • Tobacco

Intrinsic tooth discoloration occurs within the tooth. Due to the stain’s internal location within the tooth, over-the-counter whitening solutions cannot effectively remove it. It frequently has a grayish appearance. Some of the intrinsic stains are:

  • Tooth decay
  • Trauma or injury
  • Excess fluoride
  • Some medications
  • Genetics


  The enamel of the teeth wears away as a person ages. This results in a yellow appearance of the teeth. Age-related discoloration can happen due to both intrinsic and extrinsic factors.

What Are The Causes Of Tooth Discoloration?

The common causes of discoloration are consumed foods and beverages, aging, and injuries. 

Food and Beverages

Certain foods and beverages can penetrate the outer layer of the teeth and cause discoloration. Foods such as chocolate, red wine, coffee, tea, and red sauces can cause discoloration. 


Tooth discoloration can also result from using tobacco products, such as cigarettes or chewing tobacco.

Clinical research indicates that smokers are more likely than non-smokers to have tooth discoloration. Furthermore, the study discovered that smokers are less satisfied with their looks, particularly their teeth. The acidic environment in the mouth can make enamel more susceptible to discoloration.  

Aging, Injuries, And Medication

As people age, their teeth are more susceptible to staining as they become more brittle.  

When the discoloration is caused by dental injuries, only the affected tooth will darken. Permanent tooth discoloration has been linked to childhood use of tetracycline antibiotics, as reported by the Food and Drug Administration. 

How To Treat Tooth Discoloration?

Several products and procedures are available on the market that reduce stains and help teeth whitening. Depending on the underlying reason and whether the stains affect the surface or interior layers of the teeth, dentists employ several treatments for tooth discoloration. Some of them are:

Teeth whitening

Dentists can provide expert teeth-whitening procedures in the office or at home. These techniques lift and disintegrate stains from the teeth using hydrogen or carbamide peroxide. Surface stains, or extrinsic stains, respond well to professional whitening. However, certain whitening solutions can also remove deep stains on teeth or intrinsic stains.

Bleaching in the office takes roughly an hour to finish. Most at-home whitening procedures call for 30 to 60 minutes per day for up to six weeks. All the treatments have their pros and cons. It is advisable to consult a dentist before choosing the treatment method. 

Dental bonding

Dental bonding is prescribed for people with deep discoloration that cannot be treated with whitening. Using tooth-colored composite resin, stained teeth can be covered up using this process.

Compared to alternative solutions like porcelain veneers, bonding is far more economical; nevertheless, touch-ups will likely be required every five to seven years. Dental bonding might not be the best option for people with multiple discolored teeth.

Porcelain veneers

A person with widespread tooth discoloration will be treated with porcelain veneers. These thin, strong ceramic shells are similar to the color of the teeth. They are affixed to the front surfaces of the teeth by a dentist using a permanent bond to conceal discolorations and other cosmetic imperfections, such as chipped or malformed teeth

Porcelain veneers require replacement by a dentist every five to fifteen years, and they are irreversible. 

Dental crowns

Tooth discoloration can occasionally be an indication of cavities. The dentist might suggest dental crowns if a person has discoloration and weak or decaying teeth. 

A crown is a cap that resembles a tooth and is placed over the tooth to shield it from more harm. The teeth’s beauty, health, and function can all be enhanced by dental crowns.

How To Prevent Discoloration?

While intrinsic discoloration due to trauma, medications, or other diseases cannot be prevented, the intensity of the stains can be prevented by following certain measures. 

  • Brush the teeth twice a day using a soft-bristled brush and fluoride toothpaste.
  • Floss between the teeth regularly.
  • Control the use of foods that cause stains.
  • Avoid smoking
  • Increase the intake of water and rinse the mouth after drinking teeth-discoloring beverages.


Teeth discoloration is a frequent occurrence that can arise from several factors for individuals. In addition to tobacco products like cigarettes, cigars, or chewing tobacco, it is frequently brought on by foods and drinks that include coloring. 

Using teeth-whitening methods or solutions helps reduce or eliminate surface-level stains on your teeth. The dentist can perform these procedures or can be treated using at-home remedies.

Intrinsic stains, or discolorations that develop inside the teeth, can be brought on by pharmaceutical side effects, trauma, or tooth decay. A dentist appointment is advisable before choosing the treatment method.
