Take-Home Teeth Whitening Kits

1. Custom Trays

Custom trays are individually made to fit your teeth and are provided by your dentist. They come with a professional-grade whitening gel that you can apply at home.

  • It is a stronger, more effective whitening gel.

2. Over-the-Counter Kits

These whitening trays or strips are available for purchase at drugstores or online. They are generally less concentrated and offer a one-size-fits-all solution.


  • Convenient and easy to use
  • More affordable
  • No need for a dentist visit


  • Less effective than professional options

How to Choose the Right Over-the-Counter Kit

When picking a kit, consider the following:
  • Check for approval if it’s safe to use.
  • Look for reviews or recommendations.
  • Be aware of any gum sensitivity issues you will have.

Laser Teeth Whitening

It’s a professional procedure carried out in a dental office. Your dentist applies a high-concentration peroxide gel to the teeth and then uses a laser to activate the gel. This speeds up the bleaching process, offering quick and surprising results. Benefits and Potential Downsides
Aspect Benefits Considerations
Effectiveness Highly effective; visible results in one session Sensitivity issues can arise
Speed Quick process; about 30-60 minutes Will require additional sessions
Safety Performed by dental professionals Possibility of gum irritation
Longevity Results can last up to a year Results can vary based on diet and habits

Cost Considerations:

  1. Price Range: Typically more expensive than other whitening methods, ranging from $500 to $1,500 per session.
  2. Insurance: Most insurance plans don’t cover cosmetic procedures, including laser teeth whitening.
  3. Additional Costs: Maintenance or follow-up sessions could incur extra charges.
  4. Consultation Fees: Some dentists can charge a separate fee for an initial consultation.
  5. Geographical Location: Costs vary depending on your location.

Zoom Teeth Whitening

In an article, Natalie Asmussen and Sandra Serrano Pardo, DMD, explain that Zoom is a widely recognized brand in professional, in-office teeth whitening. It stands out for its light-activated hydrogen peroxide gel, which works with a specially designed UV light to accelerate the whitening process.

Whitening Process:

  1. Application of the hydrogen peroxide gel to the teeth. 
  2. A UV light is then used to activate the gel, allowing for quickly and effectively breaking down stains and discolouration. 
The entire procedure usually takes around 45 minutes to an hour.

Pros and Cons 

Aspect Pros Considerations
Effectiveness Highly effective with instant results Can cause temporary teeth or gum sensitivity
Speed Quick procedure; typically under an hour Will require additional home maintenance
Safety Performed by dental professionals Slight risk of gum irritation
Longevity Results can last up to 12-24 months Results can fade if poor dental hygiene is maintained
Convenience One-session procedure in most cases Not ideal for people sensitive to light

Deep Bleaching

It’s an advanced whitening procedure to remove stubborn, deep-set stains that other methods could not effectively tackle. The process combines in-office treatments with take-home custom trays, allowing the whitening agents to penetrate deeper into the tooth enamel. Multiple sessions are generally required for optimal results.

Deep Bleaching vs. Other Methods

Features Deep Bleaching Other Methods
Depth of Whitening Deep-set stains can be removed Can only remove surface-level stains
Treatment Duration Multiple sessions Usually fewer sessions or one-time treatment
Customization Customized take-home trays involved Generally one-size-fits-all
Effectiveness High effectiveness for stubborn stains Varies by method and type of stain
Cost Typically more expensive Varies; generally less costly

Who Should Consider Deep Bleaching?

  • People with Severe Staining
  • Previous Whitening Failures
  • Long-term Results Seekers
Internal Teeth Whitening Internal teeth whitening or internal bleaching is a specialized procedure designed to whiten teeth from the inside out. Unlike traditional methods focusing on external stains, this technique targets discolouration from within the tooth, often due to root canal treatments, trauma, or developmental issues.

Situations Where It is Used

Situations Description
After a Root Canal Treatment To treat discolouration caused by the materials used in the procedure.
Trauma-Induced Discoloration For teeth that have changed colour due to injury.
Developmental Issues To treat teeth that have internal discoloration from conditions like fluorosis.
Ineffectiveness of External Whitening When other whitening methods don’t work on internal stains.

Process and Expected Results

  1. Consult: Dentist confirms if internal whitening suits you. 
  2. Prep: A hole is drilled in the discoloured tooth. 
  3. Apply: Whitening gel goes inside the tooth.
  4. Seal: Hole is sealed to keep gel in place. 
  5. Check: Return to assess results and can apply for more gel. 
  6. Finish: Hole is sealed permanently when desired shade is reached.
