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.

You're doing all the right things helping your child avoid tooth decay: daily brushing and flossing, regular dental visits and a low-sugar diet. But although occurrences are low, they're still getting cavities.
Some children still struggle with tooth decay even with proper dental care. If this is happening to your child, your dentist may be able to give them an extra preventive boost through topical fluoride.
Fluoride has long been recognized as a proven cavity fighter. Often added in small amounts to toothpastes and drinking water, fluoride strengthens tooth enamel against acid attacks that create cavities. With topical fluoride, a dentist applies a varnish, foam or gel containing a more concentrated amount of the chemical directly to the teeth.
The effectiveness of this method in reducing tooth decay is well-founded: A number of scientific studies involving thousands of children and adolescents found an average 28% reduction in occurrences of decay among those who received the treatment compared to those who didn't.
Still, many parents have concerns about the higher fluoride concentrations in topical applications. But even at this greater amount, fluoride doesn't appear to pose any long-term health risks. The most adverse effects—vomiting, headaches or stomach pain—usually occur if a child accidentally ingests too much of the solution during treatment.
Dentists, however, go to great lengths to prevent this by using guards to isolate the solution during an application. And in the case of a foam or gel application, parents can further lower the risk of these unpleasant side effects by not allowing their child to eat or drink for at least thirty minutes after the procedure.
The evidence seems to indicate that the benefits of regular topical fluoride applications for children at high risk outweigh the possible side effects. By adding this measure to your prevention strategy, you can further protect your child from this danger to their current and future dental health.

It’s common for kids to be less than enthusiastic about visiting the dentist. For some, though, it’s even more of a challenge: A child with extreme anxiety and fear during dental visits could interfere with them receiving the dental care they need. The impact could even extend into adulthood.
Recognizing the need to reduce this high anxiety, dentistry has used a number of pharmacological tools for many years that relax a child during dental care. Sedatives have often been the only choice for reducing anxiety, especially during extensive procedures and treatments. But now there’s a promising new approach in dentistry that doesn’t depend on drugs.
Cognitive behavioral therapy (CBT), a psychotherapeutic method used for decades to treat depression, phobias and eating disorders, has been investigated recently as a possible approach for relieving children’s dental anxiety. During CBT, trained therapists use specific behavioral techniques to help patients develop mental and emotional strategies for dealing with stress.
During the usual course of CBT therapy, a therapist meets in counseling sessions with patients weekly over several months to help them change their routine thinking or behavior surrounding a stressful issue. Initially, the therapist guides the patient toward understanding the underlying causes for their negative reaction to the issue. They then work with the patient to devise an objective way to test whether those emotions and beliefs about the issue are true.
Using this effective method for changing behavioral and emotional responses for dental anxiety has had encouraging results from initial research. One study found CBT successfully reduced dental anxiety among a majority of a group of European children ages 9 through 16 who participated in the method.
CBT isn’t an overnight cure, often requires a number of months to achieve results. But for children who suffer from extreme fear of professional dental care, this drug-free method may provide long-term benefits that extend well past their childhood years.
Teeth lost to tooth decay can have devastating consequences for a child’s dental health. Not only can it disrupt their current nutrition, speech and social interaction, it can also skew their oral development for years to come.
Fortunately, we have a number of preventive tools to curb decay in young children. One of the most important of these, dental sealants, has been around for decades. We apply these resin or glass-like material coatings to the pits and crevices of teeth (especially molars) to help prevent the buildup of bacterial plaque in areas where bacteria tend to thrive.
Applying sealants is a simple and pain-free process. We first brush the coating in liquid form onto the teeth’s surface areas we wish to protect. We then use a special curing light to harden the sealant and create a durable seal.
So how effective are sealants in preventing tooth decay? Two studies in recent years reviewing dental care results from thousands of patients concluded sealants could effectively reduce cavities even four years after their application. Children who didn’t receive sealants had cavities at least three times the rate of those who did.
Sealant applications, of course, have some expense attached to them. However, it’s far less than the cost for cavity filling and other treatments for decay, not to mention future treatment costs resulting from previous decay. What’s more important, though, is the beneficial impact sealants can have a child’s dental health now and on into adulthood. That’s why sealants are recommended by both the American Dental Association and the American Academy of Pediatric Dentistry.
And while sealants are effective, they’re only one part of a comprehensive strategy to promote your child’s optimum dental health. Daily brushing and flossing, a “tooth-friendly” diet and regular dental cleanings and checkups are also necessary in helping to keep your child’s teeth healthy and free of tooth decay.
Tooth decay and developing bite problems could be major obstacles to your child's normal growth and development. Without good, preventive dental care at home and from the dentist, these obstacles could impact their health now and well into adulthood.
Here are 3 things you should do to help your child stay ahead of harmful dental problems.
Start daily hygiene early. To protect your child from tooth decay, you should begin cleaning their teeth and gums early, even before teeth appear. For your first hygiene efforts use a clean wet cloth to wipe their gums after feeding to reduce bacterial growth in the mouth. After teeth begin to erupt start brushing them with a fluoride toothpaste—a slight smear for infants and up to a pea-sized amount when they get older.
Keep sugar to a minimum. The bacteria that causes tooth decay thrive on sugar. To minimize bacterial growth, keep your child's sugar intake to a minimum by providing dental-friendly snacks and foods. Also, try to limit any sugar they eat to mealtimes rather than with snacking through the day. And avoid sending them to bed with a bottle filled with a sugary liquid (including formula and breastmilk).
Begin dental visits around age one. Dentists and pediatricians recommend regular dental visits for children starting around their first birthday. This increases the chances of detecting disease or bite problems early before too much damage occurs. Your dentist can also provide preventive measures like sealants or topical fluoride to reduce the risks of tooth decay. And early visits lessen the chance of your child developing dental visit anxiety, a phobia that could continue into adulthood.
