Watching your newborn develop into a toddler, then an elementary schooler, a teenager, and finally an adult is one of the most exciting and rewarding experiences there is. Throughout the years, you’ll note the passing of many physical milestones — including changes that involve the coming and going of primary and permanent teeth. Here are some answers to frequently asked questions about children’s dental development.
When will I see my baby’s first tooth come in?
The two lower front teeth usually erupt (emerge from the gums) together, between the ages of 6 and 10 months. But your baby’s teeth may come earlier or later. Some babies are even born with teeth! You will know the first tooth is about to come in if you see signs of teething, such as irritability and a lot of drooling. The last of the 20 baby teeth to come in are the 2-year molars, so named for the age at which they erupt.
When do kids start to lose their baby teeth?
Baby teeth are generally lost in the same order in which they appeared, starting with the lower front teeth around age 6. Children will continue to lose their primary teeth until around age 12.
What makes baby teeth fall out?
Pressure from the emerging permanent tooth below the gum will cause the roots of the baby tooth to break down or “resorb” little by little. As more of the root structure disappears, the primary tooth loses its anchorage in the jawbone and falls out.
When will I know if my child needs braces?
Bite problems (malocclusions) usually become apparent when a child has a mixture of primary and permanent teeth, around age 6-8. Certain malocclusions are easier to treat while a child’s jaw is still growing, before puberty is reached. Using appliances designed for this purpose, orthodontists can actually influence the growth and development of a child’s jaw — to make more room for crowded teeth, for example. We can discuss interceptive orthodontics more fully with you at your child’s next appointment.
When do wisdom teeth come in and why do they cause problems?
Wisdom teeth (also called third molars) usually come in between the ages of 17 and 25. By that time, there may not be enough room in the jaw to accommodate them — or they may be positioned to come in at an angle instead of vertically. Either of these situations can cause them to push against the roots of a neighboring tooth and become trapped beneath the gum, which is known as impaction. An impacted wisdom tooth may lead to an infection or damage to adjacent healthy teeth. That it is why it is important for developing wisdom teeth to be monitored regularly at the dental office.

When you think orthodontics, you may instantly picture braces or clear aligners worn by teenagers or adults. But there’s more to orthodontics than correcting fully developed malocclusions (poor bites). It’s also possible to intervene and potentially reduce a malocclusion’s future severity and cost well beforehand.
Known as interceptive orthodontics, these treatments help guide jaw growth in children while mouth structures are still developing and more pliable. But timing is critical: waiting until late childhood or puberty could be too late.
For example, we can influence an upper jaw developing too narrowly (which can cause erupting teeth to crowd each other) with an expander appliance placed in the roof of the mouth. The expander exerts slight, outward pressure on the upper jaw bones. Because the bones haven’t yet fused as they will later, the pressure maintains a gap between them that fills with additional bone that eventually widens the jaw.
Functional appliances like the Herbst appliance influence muscle and bone development in the jaws to eventually reshape and reposition them. The Herbst appliance utilizes a set of metal hinges connected to the top and bottom jaws; when the patient opens and closes their jaws the hinges encourage the lower jaw to move (and eventually grow) forward. If successful, it could help a patient avoid more invasive treatments like tooth extraction or jaw surgery.
Some interceptive objectives are quite simple in comparison like preserving the space created by a prematurely lost primary tooth. If a child loses a primary tooth before the incoming permanent tooth is ready to erupt, the nearby teeth can drift into the empty space. Without enough room, the permanent tooth could erupt out of position. We can hold the space with a simple loop device known as a space maintainer: usually made of acrylic or metal, the device fits between adjacent teeth and prevents them from drifting into the space until the permanent tooth is ready to come in.
Interceptive orthodontics can have a positive impact on your child’s jaw development, now and in the future. For these techniques to be effective, though, they must begin early, so be sure your child has a complete orthodontic evaluation beginning around age 7. You may be able to head off future bite problems before they happen.
