How Teeth Whitening Works

Teeth whitening is a treatment that uses whitening agents, and in some systems light activation, to break down discoloration within the tooth and brighten its overall shade.
Professional whitening uses higher-concentration whitening agents and should be performed after appropriate dental evaluation to help ensure both safety and predictable results.

Causes of Tooth Discoloration

Extrinsic Discoloration

Stains can accumulate on or within the outer surface of teeth from strongly colored foods and beverages such as coffee, wine, chocolate, and curry, as well as from smoking.

Intrinsic Discoloration

Intrinsic discoloration develops from changes within the tooth itself, including natural aging, developmental factors, trauma, or changes in dentin color that become visible through the translucent enamel.

Professional Whitening

Professional whitening uses clinical-strength whitening agents to brighten teeth efficiently in a controlled dental setting.

Treatment time and the number of sessions vary depending on the original tooth shade, sensitivity, whitening system, and individual response.

Home Whitening

At-home whitening products may be used according to the recommended schedule to enhance or maintain the results of professional whitening.

KIWA White Whitening-Care Toothpaste

Daily use of whitening toothpaste can help remove external surface stains and support maintenance of a brighter tooth shade after whitening.

Office Bleaching

Professional whitening uses a higher-concentration peroxide-based whitening agent under controlled conditions in the dental office. Depending on the whitening system, activation lights may also be used.
The degree of shade improvement varies by patient and depends on the original tooth color, cause of discoloration, enamel and dentin characteristics, and individual response to whitening.

Treatment results may vary from person to person, and side effects may occur. Professional evaluation is recommended before treatment.

Home Bleaching

Home whitening typically uses lower-concentration peroxide-based products than office whitening and is applied repeatedly over a longer period of time.
It may be used alone in suitable cases, but it is also commonly used to enhance or maintain the results achieved with professional whitening.

Custom-Fitted Whitening Trays

Custom-made trays are designed to fit the patient’s teeth closely, helping the whitening gel remain in the intended area while reducing unnecessary contact with the gums.

Walking Bleaching

When a tooth loses vitality, internal discoloration may develop. Walking bleaching is an internal whitening technique used to brighten a discolored non-vital tooth from within.
It is called “walking bleaching” because the whitening agent remains inside the tooth and continues working between dental visits.

Walking Bleaching Process

Vitality Check
The vitality of the tooth and the condition of the root canal are evaluated.

Root Canal Treatment
If necessary, root canal treatment is completed before internal whitening begins.

Internal Whitening Agent Placement
An appropriate whitening agent is carefully placed inside the tooth under controlled conditions.

Shade Follow-Up & Core Build-Up
The shade is re-evaluated after an appropriate interval. Once the desired result is achieved, the access cavity is sealed and restored.

Teeth Whitening FAQ

Q. What should I avoid after teeth whitening?
- A .
  
  For a period after whitening, it is helpful to limit strongly colored foods and beverages such as curry, coffee, tea, and red wine, and to avoid smoking.
  Home whitening and whitening toothpaste may also be used as part of a maintenance program when appropriate.
Q. Will my teeth become very sensitive during whitening?
- A .
  
  Temporary tooth sensitivity is one of the most common side effects of whitening. Some patients may also experience temporary gum irritation or whitening of the soft tissue if the bleaching agent comes into contact with the gums.
  These effects are usually temporary and improve after the whitening treatment is stopped or completed. Proper gum protection, appropriate whitening concentration, and professional monitoring can help reduce these risks.
Q. Does teeth whitening damage the teeth?
- A .
  
  When properly performed with clinically appropriate whitening products and protocols, professional teeth whitening is generally considered a safe cosmetic dental procedure.
  However, excessive whitening, overly frequent treatment, or inappropriate use of high-concentration products may increase sensitivity and irritation. The timing of repeat whitening should therefore be determined according to the condition of the teeth, gums, and individual response rather than by a fixed schedule alone.
