Children’s teeth begin forming before birth. As early as 4 months, the first primary (or baby) teeth to erupt through the gums are the lower central incisors, followed closely by the upper central incisors. Although all 20 primary teeth usually appear by age 3, the pace and order of their eruption varies.
Permanent teeth begin appearing around age 6, starting with the first molars and lower central incisors. This process continues until approximately age 21.
Adults have 28 permanent teeth, or up to 32 including the third molars (or wisdom teeth).
Sucking is a natural reflex and infants and young children may use thumbs, fingers, pacifiers and other objects on which to suck. It may make them feel secure and happy or provide a sense of security at difficult periods. Since thumb sucking is relaxing, it may induce sleep.
Thumb sucking that persists beyond the eruption of the permanent teeth can cause problems with the proper growth of the mouth and tooth alignment. How intensely a child sucks on fingers or thumbs will determine whether or not dental problems may result. Children who rest their thumbs passively in their mouths are less likely to have difficulty than those who vigorously suck their thumbs.
Children should cease thumb sucking by the time their permanent front teeth are ready to erupt. Usually, children stop between the ages of two and four. Peer pressure causes many school-aged children to stop.
Pacifiers are no substitute for thumb sucking. They can affect the teeth essentially the same way as sucking fingers and thumbs. However, use of the pacifier can be controlled and modified more easily than the thumb or finger habit. If you have concerns about thumb sucking or use of a pacifier, consult your pediatric dentist.

Tobacco in any form can jeopardize your child’s health and cause incurable damage. Teach your child about the dangers of tobacco.
Smokeless tobacco, also called spit, chew or snuff, is often used by teens who believe that it is a safe alternative to smoking cigarettes. This is an unfortunate misconception. Studies show that spit tobacco may be more addictive than smoking cigarettes and may be more difficult to quit. Teens who use it may be interested to know that one can of snuff per day delivers as much nicotine as 60 cigarettes. In as little as three to four months, smokeless tobacco use can cause periodontal disease and produce pre-cancerous lesions called leukoplakias.
If your child is a tobacco user you should watch for the following that could be early signs of oral cancer:
Because the early signs of oral cancer usually are not painful, people often ignore them. If it’s not caught in the early stages, oral cancer can require extensive, sometimes disfiguring, surgery. Even worse, it can kill.
Help your child avoid tobacco in any form. By doing so, they will avoid bringing cancer-causing chemicals in direct contact with their tongue, gums and cheek.
Good oral hygiene removes bacteria and the left over food particles that combine to create cavities. For infants, use a wet gauze or clean washcloth to wipe the plaque from teeth and gums. Avoid putting your child to bed with a bottle filled with anything other than water. See “Baby Bottle Tooth Decay” for more information.
For older children, brush their teeth at least twice a day. Also, watch the number of snacks containing sugar that you give your children.
The American Academy of Pediatric Dentistry recommends six month visits to the pediatric dentist beginning at your child’s first birthday. Routine visits will start your child on a lifetime of good dental health.
Your pediatric dentist may also recommend protective sealants or home fluoride treatments for your child. Sealants can be applied to your child’s molars to prevent decay on hard to clean surfaces.

Fluoride is an element, which has been shown to be beneficial to teeth. However, too little or too much fluoride can be detrimental to the teeth. Little or no fluoride will not strengthen the teeth to help them resist cavities. Excessive fluoride ingestion by preschool-aged children can lead to dental fluorosis, which is a chalky white to even brown discoloration of the permanent teeth. Many children often get more fluoride than their parents realize. Being aware of a child’s potential sources of fluoride can help parents prevent the possibility of dental fluorosis.
Some of these sources are:
Two and three year olds may not be able to expectorate (spit out) fluoride-containing toothpaste when brushing. As a result, these youngsters may ingest an excessive amount of fluoride during tooth brushing. Toothpaste ingestion during this critical period of permanent tooth development is the greatest risk factor in the development of fluorosis.
Excessive and inappropriate intake of fluoride supplements may also contribute to fluorosis. Fluoride drops and tablets, as well as fluoride fortified vitamins should not be given to infants younger than six months of age. After that time, fluoride supplements should only be given to children after all of the sources of ingested fluoride have been accounted for and upon the recommendation of your pediatrician or pediatric dentist.
Certain foods contain high levels of fluoride, especially powdered concentrate infant formula, soy-based infant formula, infant dry cereals, creamed spinach, and infant chicken products. Please read the label or contact the manufacturer. Some beverages also contain high levels of fluoride, especially decaffeinated teas, white grape juices, and juice drinks manufactured in fluoridated cities. Another source of fluoride can be found in soft drinks at fast food restaurants, when blending the syrup and carbonation with the city water supply.
Parents can take the following steps to decrease the risk of fluorosis in their children’s teeth:
