Tooth-Colored Composite fillings are often the best choice for repairing a tooth damaged by decay, fractures, cracks or other issues. The damaged or decayed portion of the tooth is removed and the void filled with the composite. Many filling types are available, and each of them has its own advantages and disadvantages. In consultation with your dentist, you can determine the best tooth restoration option for you. Composite fillings are the most widely used in modern dentistry, and since it is tooth-colored, it can be matched closely to the existing tooth, leading to better results for visible teeth. Composites, like most dental restorations, may have to be replaced someday. While they are very durable, will last many years and provide beautiful and functional teeth, they do not last forever.
