Many youngsters look forward to finding a surprise under their pillow after a visit from the “tooth fairy.” This fable may comfort children who wonder why their first teeth come out. Parents need to know that losing baby teeth, also called primary or deciduous teeth, is completely normal, but at the right time and the right “space.”

A child's first set of teeth must be lost to create room for the adult or permanent teeth that have been forming beneath them. The buds of the permanent teeth grow within a child's jawbone just under the baby teeth. The tops, or crowns, grow first, followed by the roots. Then as the roots develop, the permanent teeth push the baby teeth above them up through the gum tissues. As this happens, the roots of the baby teeth are resorbed, or melted away.

With their roots gone, eventually the baby teeth become so loose that they can be easily removed or fall out on their own, making room for the adult teeth to appear. Sometimes, when a baby tooth is so loose, it can be wiggled out. It leaves a little bleeding gum tissue that heals easily. This is also normal.

Besides making sure the tooth fairy comes, parents need to be sure that their children are evaluated to determine whether baby teeth are being lost in the right sequence so they will act as guides for the adult teeth. If teeth are lost prematurely because of decay or trauma, it is important that space is maintained for the adult teeth when they come in.

Losing a baby tooth is an important milestone in a child's life. Be sure to take a photo of that toothless smile — it will be something you treasure as your child grows up.

You may be wondering what is really happening when a baby tooth becomes loose and eventually falls or is pulled out. Read on for some answers.

What are baby teeth?
An infant's teeth begin to form before birth, by the fifth to sixth week after conception. When the baby is born, 20 primary (baby) teeth are almost completely formed inside the jaws. These first teeth, also called deciduous teeth, begin to erupt through the gums at about the time the baby begins to eat solid food. The front teeth (incisors) are usually the first to come in, at age six months to a year.

Why are they called deciduous teeth?
Deciduous means “falling off at maturity.” The same term refers to trees that lose their leaves every fall. In many mammals, including humans, it refers to the first teeth, which need to come out to make room for the larger permanent teeth to come in.

What causes the deciduous teeth to become loose?
While your child is using his primary teeth to bite and chew, his adult (permanent) teeth are quietly growing inside his jawbone. Starting with tooth “germs” (the word comes from germination, meaning the start of growth), the top part of each tooth, called the crown, grows first. Then the bottom part, or root, begins to grow and elongate. As the roots develop and the permanent teeth take up more room in the child's jaw, they begin to push against the baby teeth. This causes the roots of the baby teeth to melt away or resorb. Eventually little or nothing is left to hold the baby teeth inside the child's gums, they become wiggly, and finally they can easily be pulled out. This may leave a little bleeding gum tissue that quickly heals.

What should you watch for in the transition from primary to permanent teeth?
As the permanent teeth erupt (push through the gums and become visible), you may notice that they are too crowded, have too much space between them, or are crooked. It's a good idea to have an orthodontic (from ortho, meaning straight and dont, meaning tooth) evaluation at age five to seven. Watch to see that the baby teeth are lost in the right sequence. If one is lost prematurely, for example from decay, make sure that the space that it occupied is maintained to make room for the adult tooth that will replace it. We can help you with this.

In times of stress, people have many ways to comfort themselves. For adults, it can be habits such as eating, drinking, or smoking. For children, it is often sucking their thumb, fingers, or a pacifier. Babies have been observed in scans to suck on their fingers and thumbs even before they are born. It makes them feel secure.

When is thumb sucking a problem?
Sucking on fingers or thumbs can be a problem when it is done too vigorously and too long. A young child's jaws are soft and can change their shape to make room for the thumb if the child sucks too hard and too often. If thumb, finger or pacifier habits continue too long, the upper front teeth may tip toward the lip or not come into the correct position in the mouth.

How do you know if your child falls into the group that will suffer from the results of too much thumb sucking? It's best to visit our office so we can check on how the child's teeth and jaws are developing.

What can be done about thumb and finger sucking?
Most children naturally stop sucking their thumbs, fingers, or pacifiers between the age of two and four. The pacifier habit is easier to break than the thumb or finger sucking habit, probably because it is always easier to find their fingers or thumbs. It is a good idea to try to transfer your child's habit to a pacifier at an early age. The next steps are to cut down pacifier usage and gradually stop by 18 months.

If your child is still engaging in these habits at age three, we can recommend strategies for cutting back and stopping. Remember that positive reinforcement, in which a child is rewarded for the desired behavior, always works better than punishment for the behavior you don't like.

Also remember that finger and thumb sucking is normal. Help your child to feel safe, secure, and comfortable as the behavior will probably disappear by itself. If you are worried about your child's sucking a pacifier, thumb or fingers, please visit us to put your mind at rest.

The eruption of your child's first permanent teeth is a milestone in his or her development. As parents, you want to help your child preserve and protect their new permanent teeth so that they can last a lifetime. Dental sealants are one easy, simple, and inexpensive way to protect them from decay.

How do cavities develop?

The back teeth (premolars and molars) are formed with deep grooves on their biting surfaces that we call “pits and fissures.” These crevices are too deep for toothbrush bristles to reach. Bacteria can therefore grow and thrive inside them. The acid produced by these bacteria begins to dissolve the tooth enamel, starting the decay process.

Are new teeth more vulnerable?

Yes, the enamel surface of newly erupted teeth is more permeable and less resistant to tooth decay. As the enamel matures, it becomes more resistant.

How can you prevent decay in these new teeth?

Good oral hygiene habits, nutrition (including low sugar consumption), together with fluoride, sealants, and regular dental visits strengthen the teeth and can dramatically reduce tooth decay.

How does fluoride protect these teeth?

Fluoride makes the enamel surface harder and more impermeable and, therefore, less susceptible to acid attack and decay. Fluoride adds some protection to the deep pits and fissures of the teeth but they are still at high risk because of their shape and they often need further protection.

What are sealants and how do they work?

Sealants are protective coatings placed in the tiny pits and fissures to seal them from the bacteria and acids that promote decay. They actually “seal” the pits and fissures to prevent decay and can be used in the treatment of very early decay by arresting it. Greater use of sealants could reduce the need for subsequent treatment and prolong the time until treatment may become necessary.

One topic we are often asked about is finger or thumb sucking and/or pacifier use — a challenge that most parents or caregivers will likely face with at least one of their children. The first and perhaps most important thing to remember is that it is totally normal for babies and young children to suck their fingers, thumb or a pacifier. It only becomes a problem when it continues as the child ages or if you unnecessarily make it a problem.

For most children, the sucking instinct starts in the womb before birth. This fact is evident, as many expectant mothers are shown their child sucking fingers or a thumb during a mid or late-term sonogram. Once the child is born, the habit may continue because it provides the child with a sense of security. Other research indicates that some babies start sucking habits as a way to make contact with, test and learn about their new world outside the womb. It is interesting to note that most children typically tend to stop finger or thumb sucking habits on their own and without much intervention between the ages of two and four. However, for others it can continue much longer. And that is the scenario that parents and caregivers need to be aware of so that they can monitor sucking habits.

Children who suck their thumbs or a pacifier after the age of two have a higher risk of developing some long term negative effects from the habit. This includes but is not limited to upper jaw development issues and “buck” teeth (upper front teeth that protrude forward out of a natural position towards the lips). For this reason, some researchers feel that children should cease thumb or finger sucking and/or pacifier use by 18 months of age. However, the Academy of Pediatric Dentistry recommends that parents and caregivers encourage children to cease this habit by age three.

If you feel your child is at risk due to his/her age and habits, please contact us today to schedule an appointment for your child. After a thorough exam, we can work with you to create a strategy for helping your child overcome finger, thumb or pacifier habits.
