Medically Reviewed by Evan Frisbee, DMD on October 31, 2021 A child's mouth has 20 initial teeth, also called primary
teeth, baby teeth, or deciduous teeth: For each set of four teeth, two teeth are in the upper arch
(one on each side of the mouth) and two are in the lower arch (one on each side of the mouth). The adult mouth has 32 permanent teeth: Your teeth are used for: Biting and tearing. The central incisors and lateral incisors are mostly used for biting and cutting, and canine teeth are primarily used for tearing food. Grinding and crushing. The premolars, molars, and wisdom teeth are mostly used for chewing and grinding food. Each tooth has three main parts: crown, neck, and root. The following chart shows when your child's primary teeth (also called baby teeth or
deciduous teeth) should erupt and shed. Eruption times vary from child to child. As seen from the chart, the first teeth begin to break through the gums at about 6 months of age. Usually, the first two teeth to erupt are the two bottom central incisors (the two bottom front teeth). Next, the top four front teeth emerge. After that, other teeth slowly begin to fill in, usually in pairs -- one each side of the upper or lower jaw -- until all 20 teeth (10 in the upper jaw and 10 in the lower
jaw) have come in by the time the child is 2 ½ to 3 years old. The complete set of primary teeth is in the mouth from the age of 2 ½ to 3 years of age to 6 to 7 years of age.
Other primary tooth eruption facts:
Shortly after age 4, the jaw and facial bones of the child begin to grow, creating spaces between the primary teeth. This is a perfectly natural growth process that provides the necessary space for the larger permanent teeth to emerge. Between the ages of 6 and 12, a mixture of both primary teeth and permanent teeth reside in the mouth. While it's true that baby teeth are only in the mouth a short period of time, they play a vital role. Baby teeth: To understand the problems that decaying baby teeth can cause in permanent teeth, see Oral Health Problems in Children. Children
should usually be seen by a dentist by the age of 1 or within 6 months after their first tooth comes in. The first dental visit is usually short and involves very little treatment. This visit gives your child a chance to meet the dentist in a nonthreatening and friendly way. Some dentists may ask the parent to sit
in the dental chair and hold their child during the exam. Or you might wait in the reception area during part of the visit so that your dentist can build a relationship with your child. During the exam, your dentist will check all of your child's teeth for decay, examine their bite, and look for any potential problems with the gums, jaw, and oral tissues. If necessary, the dentist or hygienist will clean
teeth and assess the need for fluoride. They will also educate parents about oral health care basics for children, discuss dental developmental issues, and answer any questions. Topics your dentist may discuss with you might include:
You will be asked to complete medical and health information forms concerning the child during the first visit. Come prepared with the necessary information. A pediatric dentist has at least 2 more years of training beyond dental school. The training focuses on management and treatment of a child's
developing teeth, child behavior, physical growth and development, and the special needs of children's dentistry. Although either type of dentist can handle your child's oral health care needs, a pediatric dentist, their staff, and even the office décor are all geared to care for children and to put them at ease. If your child
has special needs, think about getting care from a pediatric dentist. Ask your dentist or your child's doctor what they recommend. There are no rules for when to start dental X-rays. Some children who may be at higher risk for dental problems (for example, those prone to baby bottle tooth decay or those with
cleft lip/palate) should have X-rays taken earlier than others. Usually, most children will have had X-rays taken by the age of 5 or 6. As children begin to get their adult teeth around the age of 6, X-rays play an important role in helping your dentist to see if all of the adult teeth are growing in the jaw, to look for bite problems, and to find out if teeth are clean and healthy. What your child eats affects their teeth. Too many carbohydrates, sugar (for example, from cake, cookies, candies, milk, and other sugary foods and beverages), and starches (such as pretzels and potato chips) can cause tooth decay. How long carbohydrates remain on the
teeth is the main culprit behind tooth decay. The best thing you can do as a parent is to teach your child to make healthy food choices. Here are some tips:
Parents and dentists each play an important role in making a child's first dental appointment a positive experience. Any anxiety that parents show will be picked up by the child. And an unfriendly dentist can cause unnecessary fear in the child. To help the dental visit go more smoothly: Keep in mind that it is perfectly normal for children to be fearful. Some are afraid of being separated from their parents; others are afraid of the unknown; others are afraid of being injured. A dentist who treats children will know how to cope with your
child's fears and anxiety and put them at ease. Dentist's RoleChildren may express fear in a number of ways. Some may cry; others may throw temper tantrums. Dentists often will use techniques to ease children's fears, including:
If your dentist does not take steps to ease your child's fears, consider finding another dentist. It is important that your child has a positive experience at the dentist during their early years so that they do not develop an ongoing fear of oral health care providers.
