Teeth Whitening: Everything You Need to Know
Teeth whitening is a popular cosmetic dental procedure that has gained considerable attention due to its ability to enhance the beauty of a smile. This article delves into the details of teeth whitening, its methods, and potential side effects, providing insights you can use.
Understanding Teeth Whitening
Tooth bleaching, commonly known as teeth whitening, is a prevalent practice in both general and cosmetic dentistry. People often desire whiter teeth because they are associated with youth and attractiveness?"a concept popularized by the "Hollywood smile." Children's teeth, or deciduous teeth, are typically whiter than adult teeth. As we age, adult teeth often darken due to mineral changes in the tooth's structure, decreased enamel porosity, and exposure to bacterial pigments, food, and tobacco.
The Whitening Process
Teeth whitening involves using oxidizing agents, such as hydrogen peroxide, to lighten the tooth's shade. This agent penetrates the enamel's porous structure to remove stains and can even affect the underlying dentine layer, bleaching it over time.
Whitening Methods
There are two primary methods of teeth whitening:
1. In-Office Bleaching: This method uses a high concentration of oxidizing agents for quick results. However, it poses risks such as chemical burns to the gums. To protect the soft tissues, a light-cured protective layer is applied. The bleaching agent, usually hydrogen peroxide or carbamide peroxide, is concentrated up to 35%.
2. At-Home Bleaching: This involves using a mouthguard or strip to apply a low concentration of oxidizing agent over several hours daily, typically for 5 to 14 days. While slower, this method is gentler on the gums, with the bleaching agent generally under 10% hydrogen peroxide.
Effectiveness and Challenges
Most teeth can achieve noticeable improvements with bleaching, but some stains, like tetracycline stains, may require prolonged treatment. White-spot decalcifications can become more visible after whitening.
Efforts to accelerate bleaching with light activation have produced mixed results regarding efficacy.
Potential Side Effects
Teeth whitening is not without risks. Side effects can include:
- Chemical Burns: If high-concentration agents contact unprotected tissues, they can bleach or discolor mucous membranes.
- Tooth Sensitivity: This is a common temporary side effect.
- Overbleaching: Known as "fridge-door teeth," where teeth appear unnaturally white.
Teeth can also experience a "rebound" effect, where they gradually lose their luster. Studies, such as one by Kugel et al., indicate that up to four shades of lightness may be lost within 30 days after in-office bleaching.
In conclusion, teeth whitening can significantly enhance your smile, but it's essential to understand the methods, potential side effects, and the likelihood of teeth returning to darker shades over time. Always consult with a dental professional to choose the best option for you.
