Which type of filling is known as tooth-colored and is commonly used in dentistry?

The type of filling known as tooth-colored and commonly used in dentistry is composite. Composites are made from a mixture of resin and finely ground glass particles, which allows them to closely match the natural color of teeth. This aesthetic quality makes them a popular choice for fillings in visible areas, such as the front teeth, where maintaining a natural appearance is particularly important.

Composite materials are also versatile; they can be used not only for filling cavities but also for cosmetic improvements, such as whitening and reshaping teeth. In addition to their aesthetic benefits, composites bond well to the tooth structure, which can help in restoring the integrity of the tooth. This bonding capability can contribute to a better seal and protection against further decay.

In contrast, amalgam fillings, while durable and cost-effective, are silver in color and not tooth-colored, making them less appealing for visible teeth. Glass ionomer fillings are also tooth-colored but generally have different uses and don’t match the aesthetic capabilities of composites as closely. Resin ionomer can also be tooth-colored but primarily serves specific applications and is less commonly used for general filling purposes than composites.
