Deciduous teeth, also known as baby teeth, primary teeth or baby teeth, are the first teeth. They begin to develop during the embryonic stage and begin to come out through the gums about 6 months after birth. Usually, your 20s reach 2 and a half years of age. The central and lateral incisors are mainly used for biting and cutting, and canine teeth are mainly used for tearing food.
A great way to encourage children to take care of their own teeth is to help them brush their teeth and use dental floss, and to make them see how you do it, too. These numbers are, of course, average, and some children get their teeth much earlier and others much later, which is a very normal process. At birth, people usually have 20 baby teeth (primary), which begin to come out (erupt) at about 6 months of age. During the exam, the dentist will check all of your child's teeth for cavities, examine your child's bite, and look for any potential problems with the gums, jaw, and oral tissues.
In a child's primary dentition, he or she has eight incisors and four canines. The canines, which are referred to as "fang" teeth, are used to tear and cut food. The canines are found in the front of the mouth, and the premolars are located between them. The molars are found on the back of the mouth, and are used for grinding and digesting food before it is swallowed. The adult set of teeth is comprised of 32 teeth, divided into three classes based on their purpose or shape. In some children, the first permanent molars come out as early as age six, but in others, it is around twelve.
In the upper jaw, a child has four canines, while the canines in the lower jaw have two. The canines are sharp, and are used to tear and cut food. The premolars are larger, and sit next to the canines. The molars are flat, and are used to grind and digest food. The canines serve as an anchor for the other teeth when they are growing. The second molar is usually the last tooth to erupt in a child's mouth, and comes in at about two and a half years of age.
The first teeth to erupt in a child are the two bottom central incisors, which usually erupt at approximately seven months of age. The upper incisors usually erupt two to three months after the lower incisors. The last deciduous tooth to erupt is the cuspid, or second molar, which erupts at about two and a half years of maturity.
As a child, he or she has eight incisors, including four front top teeth and four front bottom teeth. The lateral incisors, or the side teeth, primarily serve as cutting teeth. The canines are used to tear and cut food, while the molars are used for grinding and digesting food. The wisdom teeth, which erupt between ages seventeen and twenty-one, are also used for chewing and tearing food.
After the last deciduous tooth is gone, a child begins to lose the other baby teeth. He or she will have 20 teeth by the time the child is two and a half to three years of age, and the last tooth will fall out by age 12. The replacements, which are called the secondary or permanent teeth, will replace the first twenty-four deciduous teeth. The first twenty-four deciduous teeth will be replaced by a total of 32 permanent teeth by the time a child turns thirteen. In some children, the first permanent incisors erupt as early as the sixth or seventh year of life. The rest of the teeth slowly fill in, usually in pairs.
The molars are the last teeth to erupt, and are often the first to break through the gums. The first molars usually erupt at fourteen months of age, and the second molars at about two and a half years. The wisdom teeth will erupt between 17 and twenty-one, and will be the third molars. The other teeth will slowly erupt in pairs, usually by the time the child reaches the age of twenty.
The two most frontal teeth are called the central incisors and the teeth on the left and right are called the lateral incisors. The 20 teeth can be divided into three classes according to their unique shape and function during chewing. The training focuses on the management and treatment of a child's developing teeth, child behavior, physical growth and development, and the special needs of children's dentistry. Try saying the word tooth slowly and notice how the tongue first hits the inside of the incisors to produce the hard-to-write sound and then stands between the upper and lower teeth to make the seventh sound.
The AAP and the U.S. Preventive Services Task Force also recommend that children receive a fluoride varnish once they have teeth. You'll also want to clean the area between your teeth with dental floss (a special floss for cleaning your teeth) at least once a day. Therefore, encouraging and teaching your child to brush their teeth can have a lasting impact on their oral hygiene well into adulthood.
Sleeping with a bottle full of sweetened beverages, such as milk or juice, allows their sugar content to stay in your teeth for long periods of time, causing damage. Between ages 6 and 12, a mixture of primary and permanent teeth is found in the mouth.
