Four Developmental Milestones In Your Child's Oral Health

Published date field Last Updated:

We've all compared our children's milestones in the early years – height and weight, as well as when they first smiled, laughed or crawled. But do you remember their dental developmental milestones? Many parents may remember when the first tooth erupted, but more important dental moments pale in comparison to that first drooling grin. According to the Centers for Disease Control and Prevention (CDC), children's milestones are measured by how they learn, speak, move, behave and play. In oral health, developmental milestones are also important to your child's ability to eat and smile.

Baby Teeth Eruption

Even before the first tooth erupts, the primary (baby) teeth are completing their formation in your infant's jaw. The eruption of the first baby tooth paves the way for future dental checkpoints. From baby teeth to wisdom teeth, the level of care will determine the quality of your child's smile, and ultimately their overall health. According to the American Dental Association (ADA) Mouth Healthy site, dental care should begin as soon as the first tooth erupts with a trip to the dentist and continue in recommended intervals to monitor homecare and further development. And yes, baby teeth matter! They hold space for the permanent teeth, facilitate speech and nourishment and should be maintained until they are shed naturally.

Brushing, Bottle-Feeding and Thumb-Sucking

Once the baby teeth arrive, protect them as they allow the jaw to develop. Taking your child to the dentist as a toddler allows his or her oral health to be monitored for early problems and abnormalities. It's important to monitor the following:

  • Supervised and supported brushing and flossing
  • Thumb- or finger-sucking effects and cessation
  • Nutrition and baby bottle use
  • Supplemental fluoride treatments

Baby teeth can develop cavities if they lack homecare or have a diet that is high in fructose sugars, especially when ingested through a bottle. Your dentist or dental hygienist can advise you on what should be put in a bottle and when to discontinue bottle use. Additionally, they can provide instruction on oral hygiene and fluoride treatment to prevent decay. Dummy use, finger- and thumb-sucking are all normal to a degree, according to the ADA, but should be discouraged if it affects the proper development of the teeth and jaw. By seeking dental care early, your baby will be on the right track for healthy development.

Mixed Dentition

Once kids begin to lose baby teeth and the permanent teeth begin to erupt, they have a "mixed dentition," which brings specific concerns. Your child may begin to participate in sports, show signs of teeth crowding and make poor choices in their diet. Again, your dental professional will recognise what preventative or interventional treatment is necessary. This may include:

  • A sports mouth guard to protect the teeth and jaw.
  • Referral to an orthodontist.
  • Nutritional counseling to help your child make healthy dietary choices.
  • Fluoride treatment and dental sealants to prevent further decay.

Braces and Wisdom Teeth

Once your child enters his or her teen years, stress the connection between a healthy mouth and healthy body. Teenagers can appreciate how important a healthy smile is, and take responsibility for keeping it that way. At this age, they may have braces or just finished orthodontic treatment. Teenagers' oral hygiene habits for the prevention of cavities and gum disease should be a priority as well, and the eruption of the wisdom teeth need monitoring. Their dentist or dental hygienist can provide the tools needed to transition to a healthy adult mouth. They will focus on the following:

  • Proper diet, nutrition and exercise.
  • Brushing, flossing and fluoride use can be used to potentially curb specific problems.
  • Monitoring the eruption of wisdom teeth and referral to oral surgeon if needed.

Most teenagers will not have enough space in the jaw for the third molars to erupt. If this is the case, it is vital to have them removed to avoid future problems – including infection, pain and physical effect on adjacent teeth. Very often, if they have had braces, the orthodontist will watch these teeth by taking a special x-ray and making the oral surgery referral themselves.

Developmental milestones are important in your child's life, from infancy to young adulthood. Your understanding of these milestones can transition to them taking responsibility for their overall health as an adult. By beginning dental care early and upholding regular visits to the dentist, you're setting your child on the right track for a lifetime of healthy smiles.
