03/11/2026 A professional teeth whitening treatment can improve the colour of your natural teeth, lifting it by several shades, often in as little as an hour. Dental Pearl uses the highest-quality, professional-strength hydrogen peroxide-based whitening products to remove stains deep within tooth enamel.
These products are applied topically to your tooth surfaces, where they soon penetrate the tooth enamel and help to remove stains, leaving the enamel looking brighter and whiter.
These products are far stronger than anything you can purchase over the counter. Most importantly, your treatment is supervised by dental professionals, so it is safe and provides optimal results quickly. We can help you achieve your most youthful and brightest smile.
What Causes Tooth Discoloration?
Tooth discoloration can be extrinsic, meaning it is external and affects your tooth enamel. Alternatively, some teeth discolor internally or intrinsically.
Extrinsic Tooth Staining
Most people find that their teeth begin to discolor over time. Often, this is due to tooth enamel erosion caused by exposure to acids in foods and beverages. These acids are also produced by bacteria in dental plaque.
Tooth enamel is relatively opaque, but as it thins, it gradually reveals the color of the dentin beneath. Dentin is darker, hence teeth begin to look discolored and dingy.
Consuming lots of highly colored foods and beverages can cause tooth discoloration. The colours in these foods can penetrate tooth enamel, staining and darkening it.
Another reason is smoking, as the nicotine found in tobacco products is well known for staining teeth.
Intrinsic Teeth Staining
The inner parts of a tooth can become stained if exposed to certain antibiotics while the tooth is still developing. Tooth discoloration can also occur because of an older root canal.
Intrinsic teeth staining requires a different whitening approach, as applying whitening products topically may not be effective. Instead, we would have to consider bleaching the tooth internally or otherwise covering it with a porcelain veneer to create a uniformly white smile.
