A bright, white smile is a strong sign of health and confidence. Unfortunately, even the healthiest teeth can become discoloured over time, leading to a less vibrant appearance.
It’s only after you understand the different types of tooth discolouration that you can determine the most effective treatment options that’s right for your situation.
To start with, tooth stains are categorized as either extrinsic or intrinsic, and each stems from distinct causes and requires tailored solutions.
Let’s dive deeper.
Extrinsic Stains: Surface-Level Discolouration
Extrinsic stains are those that affect the outer layer of the tooth, the enamel. These stains are typically caused by external factors and are relatively easier to address. Common culprits include:
- Food and beverages. Dark-coloured beverages like coffee, tea, red wine, and cola contain chromogens, substances that adhere to the enamel and cause staining. Similarly, foods like berries, soy sauce, and certain spices can also contribute to extrinsic discolouration.
- Tobacco use. Smoking or chewing tobacco introduces tar and nicotine, which can deeply stain the enamel, resulting in a yellowish-brown hue.
- Poor oral hygiene. Inadequate brushing and flossing allow plaque and tartar to accumulate on the tooth surface, creating a breeding ground for stain-causing substances.
- Certain medications. Some mouthwashes and topical medications containing chlorhexidine or stannous fluoride can cause extrinsic staining with prolonged use.
Extrinsic stains are often treatable with professional dental cleanings and surface-level whitening treatments. A thorough cleaning by a hygienist can remove plaque, tartar, and surface stains, restoring some of the tooth’s natural whiteness. For more stubborn extrinsic stains, over-the-counter or professional teeth whitening products can be effective.

Intrinsic Stains: Deep-Seated Discolouration
Intrinsic stains, on the other hand, originate from within the tooth structure, affecting the dentin. These stains are more challenging to remove and often require more intensive treatments. Causes of intrinsic stains include:
- Dental trauma. Injuries to the tooth can damage the blood vessels and nerves within the pulp, leading to discolouration. This can manifest as a gray, pink, or brownish hue.
- Excessive fluoride exposure. Fluorosis, caused by excessive fluoride intake during tooth development, can result in white spots or streaks on the enamel. In severe cases, it can cause brown or yellow discolouration.
- Certain medications. Tetracycline antibiotics, when taken during tooth development (before the age of eight), can cause permanent gray or brown staining.
- Genetic conditions. Some genetic disorders, such as dentinogenesis imperfecta and amelogenesis imperfecta, can affect the formation of dentin and enamel, leading to intrinsic discolouration.
- Aging. As we age, the enamel naturally thins, revealing the underlying dentin, which is naturally more yellow. This can give the teeth a darker appearance.
Treating intrinsic stains requires a more comprehensive approach. Professional teeth whitening may offer some improvement, but more advanced procedures may be necessary, which our Brampton dentists can accommodate. These procedures include:
- Dental veneers. Thin, custom-made porcelain shells that are bonded to the front surface of the teeth, masking discolouration and improving overall aesthetics.
- Dental crowns. Caps that cover the entire visible portion of the tooth, providing a durable and aesthetically pleasing solution for severely discoloured teeth.
- Internal bleaching. A procedure in which a bleaching agent is placed inside the tooth to lighten the dentin from within. This is often used for teeth that have been discoloured due to trauma.
Determining the Type of Stain
The first step in addressing tooth discolouration is to determine whether the stains are extrinsic or intrinsic. A thorough dental examination by a qualified dentist is essential for accurate diagnosis. Your dentist will assess the colour, location, and severity of the stains, as well as consider your medical and dental history.
Prevention Is Key
While treatments are available for both extrinsic and intrinsic stains, prevention is always the best approach. Here are some tips for maintaining a bright, healthy smile:
- Practice good oral hygiene by brushing twice daily and flossing once a day.
- Limit consumption of stain-causing foods and beverages.
- Avoid tobacco use.
- Schedule regular dental checkups and cleanings.
- If you are prescribed medications that can cause staining, consult your doctor or dentist about potential alternatives or preventative measures.
Understanding the difference between extrinsic and intrinsic tooth stains empowers you to make informed decisions about your oral health. If you are concerned about tooth discolouration, consult your dentist for a personalized assessment and treatment plan.
