Your child’s dental needs change constantly as they grow — what matters at age 1 looks nothing like what matters at age 12. Knowing what to expect (and when) makes it easier to stay ahead of problems instead of reacting to them.
Here’s a stage-by-stage guide from the team at Pacific Dental Group in North Hollywood.
Infancy (0–12 Months): Before the First Tooth
Dental care technically starts before any teeth appear. Wiping your baby’s gums with a soft, damp cloth after feedings helps establish good habits and reduces bacteria buildup. Once the first tooth erupts — usually between 6 and 10 months — switch to a soft, tiny-bristled toothbrush with a rice-grain-sized smear of fluoride toothpaste.
This is also when we recommend scheduling that first dental visit, ideally by your child’s first birthday.
Toddlers (1–3 Years): The Cavity-Prevention Window
By age 3, most children have all 20 baby teeth. This stage is critical for preventing early childhood cavities, which are more common than many parents expect. A few habits make a big difference: avoid putting your toddler to bed with a bottle of milk or juice, limit sugary snacks and drinks between meals, and start supervised brushing twice a day, working up to a pea-sized amount of toothpaste around age 3.
Preschool & Early Elementary (4–6 Years): Losing the First Teeth
Somewhere around age 5 or 6, the first baby teeth start to wiggle loose, usually the lower front teeth. This is also when the first permanent molars — the “six-year molars” — come in behind the baby teeth, often without any teeth being lost first. Because these molars have deep grooves, they’re highly cavity-prone, which is why we often recommend dental sealants as soon as they erupt.
Mixed Dentition (6–12 Years): Baby Teeth and Adult Teeth Together
This stretch can look a little chaotic — a mouth with both baby and permanent teeth, gaps, and teeth coming in at odd angles. Most of it is completely normal. It’s also the age range where we start keeping an eye on bite and spacing issues, since early orthodontic evaluation (recommended around age 7 by most orthodontic associations) can catch problems while the jaw is still developing.
Sports become more common in this age group too, which makes mouth guards worth discussing if your child plays anything with contact or fast-moving equipment.
Adolescence (13–18 Years): Independence and Wisdom Teeth
Teenagers are old enough to manage their own oral hygiene, but that independence sometimes means checkups slip. Regular visits still matter here — for cavity checks, but also for monitoring wisdom teeth, which typically start developing in the late teens and may need evaluation for extraction. This is also a common age for starting Invisalign or other orthodontic treatment, and for teens interested in cosmetic options like teeth whitening as they head into young adulthood.
One Team, Every Stage
Because your child’s dental needs shift so much over the years, having a dentist who can grow with them — from first tooth to wisdom teeth — makes life easier for everyone. At Pacific Dental Group, we see patients through every one of these stages, with a $49 Children’s Complete Checkup and a team that knows how to keep kids (and parents) comfortable.
