Even though it can make us feel self-conscious, tooth discoloration is extremely common and can be caused by a variety of disorders. Understanding these probable causes is critical for anyone who wishes to keep their pearly white smile, as it allows you and your dentist to collaborate in order to avoid and/or manage tooth stains. In that spirit, here are the top eight causes of tooth discolouration.

A radiant white smile can greatly improve your appearance and self-esteem. However, tooth stains and discoloration are common issues that many individuals face. Understanding the causes of these dental concerns is crucial for maintaining a radiant smile. In this blog post, our dentist in Heritage will explore some of the most common culprits behind tooth stains and discoloration, shedding light on how to prevent and address these issues effectively.

1. Food and Beverages

One of the primary contributors to tooth stains is the consumption of certain foods and drinks. Coffee, tea, red wine, berries, and deeply pigmented foods can leave stubborn stains on your teeth over time. Limiting the intake of these items or practicing good oral hygiene immediately after consuming them can help minimize discoloration.

2. Tobacco Use

Smoking or using tobacco products is a notorious cause of tooth stains. The tar and nicotine in tobacco can quickly turn teeth yellow or brown. Quitting tobacco not only improves your overall health but also plays a significant role in maintaining a bright, white smile.

3. Poor Oral Hygiene

Inadequate brushing and flossing can lead to the accumulation of plaque and tartar on teeth, contributing to discoloration. Establishing a thorough oral care routine, including regular dental teeth whitening near you with check-ups and cleanings, is essential for preventing and addressing stains caused by poor oral hygiene.

4. Aging

The tooth’s enamel naturally erodes with age, exposing the dentin, which is yellow in colour. While aging is inevitable, practicing good oral hygiene and avoiding excessive consumption of staining substances can slow down the discoloration process.

5. Genetics

Some individuals are genetically predisposed to having naturally darker or yellower teeth. While genetics play a role in tooth colour, maintaining proper oral hygiene practices can still help prevent excessive staining.

6. Medications

 Certain medications, such as tetracycline antibiotics, antihistamines, and certain antipsychotics, can cause teeth discoloration as a side effect. If you’re on medication and notice changes in your tooth colour, consult your dentist to explore possible solutions.

7. Fluorosis

Excessive exposure to fluoride during tooth development, often from swallowing fluoride toothpaste during childhood, can lead to a condition called fluorosis. This may result in white or brownish stains on the teeth. Using an appropriate amount of fluoride toothpaste and monitoring children’s dental hygiene can help prevent fluorosis.

Treatment of Teeth Stain

To address tooth discoloration, there are numerous treatment options available. These are some examples:

  • Maintaining good dental hygiene includes brushing and flossing every day.
  • Brush your teeth with baking soda twice a week.
  • Using over-the-counter treatments for teeth whitening in SE Calgary (whitening toothpastes, strips, trays, and gels).
  • Professional whitening procedures in the workplace

Some tooth discoloration is irreparable; in that instance, your dentist can conceal it using veneers, crowns, and white composite fillings.


Maintaining a bright, white smile requires a combination of good oral hygiene practices, lifestyle choices, and awareness of potential contributing factors. By understanding the common causes of tooth stains and discoloration, you can take proactive steps to preserve your dental aesthetics and promote overall oral health. Regular dental check-ups with your dentist near you, professional cleanings, and lifestyle adjustments will go a long way in ensuring your smile remains radiant and confident.
