Teeth help you chew your food, making it easier to digest. Pulp Pulp is found at the center and core of your tooth and contains the blood vessels, nerves, and other soft tissues that deliver nutrients and signals to your teeth. But with inadequate dental care, the gums may become diseased and shrink, exposing the cementum to harmful plaque and bacteria. Cementum has a light yellow color and is usually covered by the gums and bone. It's softer than enamel and dentin the best way to protect this softer tissue from decay is by taking good care of your gums. Dentin is not quite as hard as enamel, so it's at greater risk for decay should the enamel wear away.Ĭementum This tissue covers the tooth root and helps anchor it into the bone. Enamel is made up of hydroxyapatite, phosphorous, and calcium.ĭentin Underneath the enamel you find dentin, which is calcified and looks similar to bone. Harder than bone, enamel protects the vital tissues within the tooth. These include:Įnamel This is the visible substance that covers the tooth crown. Your teeth contain four kinds of tissue, and each does a different job. The root extends below the gum line and helps anchor the tooth into the bone. Most adults have 32 permanent teeth.Ī tooth is divided into two basic parts: the crown, which is the visible, white part of the tooth, and the root, which you can’t see. Adult teeth start to grow in between ages 6 and 12.Between ages 6 and 12, these primary teeth begin to fall out to make way for the permanent set of teeth. ![]() The 20 primary teeth are in place between ages 2 ½ and 3 and remain until around age 6.The crown of a tooth forms first, while the roots continue to develop even after the tooth has erupted.For example, a baby’s first tooth appears at around six months, but development of those teeth actually begins during the early second trimester of pregnancy," says Dr. "Tooth development begins long before your first tooth becomes visible.According to Shantanu Lal, doctor of dental surgery and associate professor of dental medicine at Columbia University Medical Center in New York City, teeth tend to erupt in a symmetrical manner, meaning that the top molar on your left side should grow in at about the same time as the top molar on the right.
