In-office bleaching or dentist whitening allows significant color change to be accomplished within in a short time span of only one hour or so, making it major benefit of professional whitening.
During in-office tooth whitening, the tooth whitening dentist applies a protective gel to your gums or a rubber shield to protect the oral soft tissues. A relatively high-concentration peroxide gel is then carefully applied to the teeth by the tooth whitening dentist. Generally, the peroxide remains on the teeth for several 15 to 20 minute intervals, a special light (such as laser light or plasma arc light) is used to enhance and activate the action of the tooth whitening agent.
For individuals with particularly stubborn staining may be advised to return for one or more additional tooth whitening sessions, or may be asked to continue with a home whitening kit.
Advantages of In-Office Whitening
- Professional tooth whitening is a safe form of tooth bleaching
- Gum and tooth sensitivity are more controllable today due to thicker peroxide gels and the use of desensitizers such as potassium nitrate and fluoride.
Disadvantages of In-Office Whitening
- In-office bleaching is more expensive than take-home bleaching alternatives.
- In-office bleaching is not a permanent solution. After the one hour whitening treatment is completed, teeth do still resume accumulating stains. Many dentists therefore recommend the home bleaching maintenance kits with a follow-up lower-percentage bleach
Types of In-office Tooth Whitening
Whitening teeth with in-office teeth whitening is determined by the concentration of peroxide in the whitening agent and the amount of time the whitening agent is placed on the surface of teeth.
