Tooth Colored Fillings Brooklyn, MN

The external part of the tooth is called the enamel, which is arguably the hardest material found in the animal kingdom. It consists of very closely knit calcium crystals and contains no living tissue. Dental porcelains easily and efficiently imitate the enamel part of a tooth. The inner part of the tooth is the dentin, which is more porous and similar to bone. It consists of microscopic tubes of collagen with calcium crystal deposits. Dentin is living and very sensitive. Feeling in the dentin is transmitted through the pulp, or nerve tissues, in the center of the tooth. To mimic the dentin that is natural the teeth, today’s dental composite resins are common in non-amalgam fillings. These composites are made of a plastic resin and silica filler.
