In today’s image-conscious world, a bright, white smile is considered a symbol of health, vitality, and attractiveness. As a result, teeth whitening has become one of the most popular cosmetic dental procedures.Â
What Causes Tooth Discoloration?
It’s important to understand why teeth become discolored in the first place. Tooth discoloration can be categorized into three main types:
- Extrinsic discoloration: Occurs on the tooth surface and is often caused by:
- Food and beverages that stain (coffee, tea, red wine)
- Tobacco use
- Poor oral hygiene
- Intrinsic discoloration: Occurs within the tooth structure and can be caused by:
- Medications (e.g., tetracycline antibiotics)
- Excessive fluoride exposure during tooth development
- Tooth trauma
- Aging
- Age-related discoloration: A combination of extrinsic and intrinsic factors naturally occuring as we age.
How Does Teeth Whitening Work?
Teeth whitening works by using chemical agents to break down stain-causing compounds in tooth enamel. Their are two main active ingredients used in teeth whitening products:
- Hydrogen peroxide
- Carbamide peroxide
These compounds break down into oxygen molecules, which penetrate the enamel and dentin layers of the tooth. The oxygen molecules react with the discolored molecules in your teeth, breaking the bonds that hold them together. This process effectively “bleaches” the teeth, making them appear whiter.
Types of Teeth Whitening Methods
Several methods are available for teeth whitening, each with its own pros and cons:
1. In-Office Professional Whitening

What to Expect During and After Whitening
During the Whitening Process

- Uneven results: Initially, teeth may whiten unevenly, but this typically evens out by the end of the treatment.
After Whitening

- Gradual fading: Teeth will naturally start to discolor again over time, especially if exposed to staining foods and drinks.
- Maintenance: Touch-up treatments every 6-12 months are recommended, depending on your habits and the whitening method used.
How Long Do Teeth Whitening Results Last?
The longevity of teeth whitening results vary considerably based on several factors:
- Whitening method used: Professional treatments last longer than over-the-counter products.
- Oral hygiene habits: Good oral care helps maintain results.
- Diet: Consuming staining foods and drinks shorten the duration of results.
- Lifestyle factors: Smoking and other habits can affect how long results last.

While teeth whitening is safe when done correctly, there are some potential risks and side effects to be aware of:
- Tooth sensitivity: The most common but only temporary side effect.
- Gum irritation: If whitening product has prolonged gum contact.Â

Dr. Dominguez has a talent in saving teeth involving complicated root canals, restoring teeth broken at or beneath the gum line.
A dental drill can cause tiny tooth fractures. The high speed produces heat and pressure making patients uncomfortable.
A dental laser doesn’t have any of these problems to deliver minimally invasive root canal procedures. Dr. Dominguez delivers unparalleled results with each root canal procedure.
Advanced lasers decrease the time for root canal procedures. Lasers minimize or eliminate gum bleeding, allowing for faster healing following a root canal than with traditional root canals procedures.
