Peroxide-based tooth whitening is safe and effective when used properly. Common side effects like tooth sensitivity are mild and temporary, with no evidence of significant health risks.
Area of Science:
- Dental Science
- Toxicology
- Material Science
Background:
- In-office tooth whitening with hydrogen peroxide (H₂O₂) has a long history of safety.
- At-home peroxide-based whitening, introduced in 1989, has raised safety concerns despite proven efficacy.
Purpose of the Study:
- To review and discuss the safety of peroxide-based tooth whitening materials.
- To examine biological properties, toxicology, and clinical considerations of H₂O₂ and chlorine dioxide in whitening.
Main Methods:
- Review of accumulated safety data over the past two decades.
- Analysis of studies on tooth whitening safety, including biological properties and toxicology of peroxides.
Main Results:
- Peroxide-based tooth whitening is demonstrated to be safe and effective when applied correctly.
- Most frequent side effects include mild to moderate, transient tooth sensitivity and gingival irritation.
Conclusions:
- No significant health risks are associated with current tooth whitening practices.
- Potential adverse effects can arise from improper application, overuse, or unsuitable products.
- Dental professionals can ensure safe and effective whitening by understanding materials and potential risks.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
