5 Causes of Teeth Discoloration and what to do? - Calgary Dental Clinic

Good dental hygiene is important in taking care of your overall health. It includes brushing your teeth twice a day and, flossing daily, visiting your dentist regularly for professional cleanings and check-ups. Also, good dental hygiene can prevent gum disease, tooth decay, and other dental problems.

Teeth discoloration is a common sign of poor dental hygiene. Discoloured teeth can signify that you are not brushing your teeth regularly or may have developed a dental condition. If you do not brush your teeth regularly, bacteria and plaque can build up on your teeth, causing discoloration.

If you do not brush your teeth regularly and consume these staining beverages and foods, your teeth could discolour. There are certain effective daily routines you can follow for ideal dental hygiene. Because, poor dental hygiene can also lead to gum disease, cavities, and other oral health problems, which can cause discoloration. Therefore, it is important to maintain good oral hygiene habits to prevent discoloration and other dental problems.

What causes discoloration

Dental treatments can help to reduce teeth discoloration, but the effectiveness of treatment depends on the cause of the discoloration. Teeth stained due to consuming certain foods and drinks, such as coffee and tea, maybe whitened with professional teeth whitening treatments. Dental veneers and crowns may also cover up teeth with severe discoloration.

On the other hand, teeth that are discoloured due to medications or medical conditions may not be as easily treated and may require specialized treatments such as laser whitening. Therefore, it is important to consult a dentist to determine the best treatment option for reducing teeth discoloration.

#1. Aging

Aging As we age, the enamel on our teeth naturally begins to thin out, making our teeth more transparent. This causes the yellow dentin layer of the tooth to become more visible, leading to discoloration of the teeth. Additionally, as we age, our gums may recede, further exposing the dentin layer of our teeth. 

Over time, the enamel on the teeth can become thinner, allowing for the underlying dentin to show through. Dentin is a yellowish material that can give your teeth a yellowish or brownish tint. Additionally, as we age, our saliva production decreases, leaving our mouths with less saliva to keep our teeth clean and healthy. As bacteria builds up, it can cause plaque and tartar buildup on the teeth, making them yellow.

#2. Food choices

Staining from Food and Beverages Certain food and beverages can stain our teeth if consumed in excess. These items include coffee, tea, red wine, dark soft drinks, berries, and tomato-based sauces. To reduce the risk of staining from these foods and drinks, it is important to brush your teeth or rinse with water soon after consumption.

#3. Poor dental hygiene

Poor Dental Hygiene Maintaining healthy dental hygiene is key to preventing teeth discoloration. Brushing your teeth at least twice a day with fluoride toothpaste and flossing daily will help keep your teeth looking whiter and brighter. Additionally, it is important to get regular checkups and cleanings by your dentist to help prevent discoloration.

#4. Smoking 

Smoking cigarettes or other tobacco products can cause teeth to become stained yellow or brown over time. The nicotine and tar in cigarettes can cause staining on the surface of one’s teeth and can be difficult to remove without professional help. Quitting smoking is the best preventative measure to ensure that your teeth do not become discoloured. 

#5. Certain Medications

Certain medications can have the side effect of causing teeth discoloration. These medications include tetracycline antibiotics, some high blood pressure medications, and chemotherapy drugs. If you are taking any of these medications, it is important to speak with your doctor or dentist about what can be done to prevent tooth discoloration.


Regular dental checkups are an essential part of preventing tooth discoloration. Regular visits to the dentist will help identify the cause of discoloration in the early stages to treat it properly. An ideal oral hygiene routine can help prevent teeth discolouration.

During these checkups, the dentist can advise on dental care and oral hygiene, including the best toothpaste and mouthwashes and dietary habits to prevent teeth discoloration. Regular dental checkups allow you to maintain healthy and white teeth for a lifetime.
