What Causes Tooth Discoloration?

Tooth discoloration can occur for many reasons, including:

Daily habits

• Coffee and tea
  
• Red wine
  
• Soft drinks
  
• Dark sauces (soy, balsamic, tomato-based)
  
• Candies and foods with strong dyes
  

Lifestyle factors

• Smoking or vaping
  
• Chewing tobacco
  

Medical and natural causes

• Certain medications
  
• Natural aging
  
• Thinning enamel over time
  
• Trauma to a tooth
  

These factors can cause external staining (on the enamel) or internal discoloration (within the tooth). Professional whitening is extremely effective for most external stains and mild internal discoloration.

Are Teeth Whitening Products Safe?

When used correctly, whitening products that contain peroxide—either hydrogen peroxide or carbamide peroxide—are considered safe and effective.

To ensure safety, look for whitening products that are:

• Evaluated or approved by the Canadian Dental Association
  
• Recommended by dental professionals
  
• Properly applied according to instructions
  

Professional treatments are always the safest and most predictable, as they allow for customized whitening strength, controlled application, and desensitizing measures when needed.

How Do Teeth Whitening Products Work?

Most whitening gels use peroxide-based agents that enter the enamel and release oxygen molecules. These molecules break apart stain compounds without damaging the tooth structure.

Whitening can be enhanced by:

• Higher-concentration gels
  
• Whitening lamps or LED lights
  
• Custom-fitted trays for even gel distribution
  
• Professional supervision
  

Zoom! Whitening combines advanced peroxide gel with an activating light source to accelerate results and achieve maximum brightness in a single visit.

Will Whitening Cause Sensitivity?

Temporary tooth sensitivity is one of the most common side effects of whitening. It generally:

• Occurs during or shortly after treatment
  
• Subsides within a few hours to a few days
  
• Can be minimized with modern desensitizing formulations
  

Many whitening systems now include ingredients such as potassium nitrate and fluoride, which strengthen enamel and reduce sensitivity.

If you already have sensitive teeth, your dentist may recommend a gentler whitening approach or pre-treatment with desensitizing toothpaste.

What Is the Whitening Process?

Here is what you can expect during a professional teeth whitening appointment.

Before the Appointment

Your dentist will:

• Examine your teeth and gums
  
• Identify the cause of discoloration
  
• Ensure whitening is safe and appropriate
  
• Discuss realistic results based on your tooth colour and enamel condition
  

Professional cleaning may be recommended beforehand for the best results.

During the Appointment

In-office Zoom! Whitening typically includes:

1. Protection of the gums and soft tissues
   
2. Application of the Zoom! whitening gel
   
3. Activation of the gel using a specialized LED light
   
4. Several whitening cycles depending on desired brightness
   
5. Rinsing and application of desensitizing agents
   

The entire process usually takes 60–70 minutes.

After the Appointment

You may experience mild sensitivity for up to 24–48 hours. Avoid dark foods and beverages for at least 48 hours as teeth are more susceptible to staining immediately after whitening.

Risks to Be Aware Of

Whitening is safe when performed correctly, but some considerations include:

• Temporary tooth sensitivity
  
• Gum irritation if the gel contacts soft tissue
  
• Uneven results on teeth with fillings, crowns, or veneers
  
• Over-whitening from excessive or unsupervised use of whitening kits
  

Your dentist will assess whether whitening is appropriate and guide you to the safest treatment option.

How Do I Use Whitening Products at Home?

If you choose a take-home whitening kit:

• Follow the instructions carefully
  
• Use only the recommended amount of gel
  
• Do not exceed the suggested wear time
  
• Contact your dentist if irritation or sensitivity occurs
  

For the brightest, fastest, and safest results, in-office treatment remains the gold standard.
