Summary
Transient tooth sensitivity is a common side effect of at-home bleaching, but it is not well understood. This review covers pulpal concerns and prevention strategies for tooth sensitivity during at-home whitening treatments.
Area of Science:
- Dentistry
- Dental Materials
Background:
- At-home bleaching is a popular cosmetic dental procedure.
- Transient tooth sensitivity is the most frequent adverse effect.
- The underlying mechanisms of this sensitivity remain unclear.
Purpose of the Study:
- To critically appraise existing literature on tooth sensitivity from at-home bleaching.
- To review pulpal concerns and prevention methods for at-home whitening treatments.
Main Methods:
- Literature review of scientific articles.
- Critical appraisal of studies on tooth sensitivity and bleaching.
- Synthesis of findings on incidence, long-term effects, pulpal concerns, and prevention.
Main Results:
- Tooth sensitivity is a common, though not fully understood, side effect of at-home bleaching.
- The review consolidates information on pulpal issues and effective prevention strategies.
Conclusions:
- Further research is needed to fully elucidate the mechanisms of tooth sensitivity.
- Implementing preventive measures can mitigate discomfort during at-home bleaching.

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
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.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
