Good dental habits don’t start at age five or six — they start at birth. And as a parent, you have enormous influence over whether your child grows up with a healthy relationship with dental care or one defined by anxiety and avoidance. The good news is that with the right guidance, most children can have healthy teeth and positive dental experiences throughout their entire childhood and into adulthood.
Here’s a practical, age-by-age guide to children’s dental health.
Before the First Tooth (Birth to ~6 Months)
Oral hygiene starts before the first tooth even arrives. Gently wiping your newborn’s gums with a clean, damp cloth after feedings removes milk residue and begins establishing the routine of oral care. This also prepares the mouth for the introduction of a toothbrush when teeth arrive.
Avoid putting your baby to bed with a bottle of milk or juice — this is a primary cause of early childhood caries (also known as “baby bottle tooth decay”). If your baby needs a bottle at bedtime, fill it with water only.
The First Tooth (Around 6 Months)
As soon as the first tooth appears, it’s time for a soft-bristled infant toothbrush and a rice-sized smear of fluoride toothpaste. The American Academy of Pediatric Dentistry (AAPD) recommends using fluoride toothpaste from the very first tooth — even in infants — in an amount no larger than a grain of rice.
This is also around the time to schedule your baby’s first dental visit. The AAPD and the American Dental Association both recommend that children see a dentist within six months of the first tooth erupting, or by their first birthday — whichever comes first.
Ages 1–3: Building the Foundation
The first dental visits are primarily about establishing a positive relationship with dental care, monitoring tooth development, and educating parents. Dr. Collura will check for signs of early decay, evaluate bite development, and provide guidance on:
- Brushing technique (you should be doing it for them at this age)
- Fluoride needs based on your water supply
- Diet and its impact on tooth decay
- Pacifier and thumb-sucking habits
- When to expect additional teeth
By age three, most children have a full set of 20 primary teeth. These teeth matter. They hold space for permanent teeth, support speech development, and allow for proper chewing and nutrition. Losing them early to decay can affect the development of the permanent teeth that follow.
Ages 4–6: When Cavities Become More Common
The preschool and early school years are when cavities become more common — partly because children are snacking more frequently, partly because they’re still developing the manual dexterity needed to brush effectively on their own. Continue brushing your child’s teeth until they demonstrate consistent technique, usually around age six to seven.
This is also when fluoride varnish applications become particularly valuable — Dr. Collura applies these at regular checkups to strengthen enamel and reduce decay risk.
Ages 6–12: The Mixed Dentition Years
Around age six, the first permanent molars erupt — even before the baby teeth start falling out. These “six-year molars” are among the most important teeth in the mouth and are also highly susceptible to decay because of their deep grooves and pits. This is the ideal time to have dental sealants placed.
According to the National Institute of Dental and Craniofacial Research, dental sealants reduce the risk of cavities in molars by nearly 80 percent in the first two years and continue to protect for several more years afterward. At Turners Falls Dental, we use only BPA-free sealant materials.
The second set of sealants should be placed around age 12 when the second permanent molars come in.
The Teenage Years: New Challenges
Teenagers face unique dental health challenges: hormonal changes that increase susceptibility to gum inflammation, increased consumption of sugary and acidic drinks, sports injuries, and often, the arrival of wisdom teeth. This is also the age when many patients begin orthodontic treatment.
For teens who want straighter teeth without traditional braces, SureSmile® clear aligners — available at Turners Falls Dental — offer a discreet, effective option that allows normal eating and easier cleaning compared to fixed braces.
Teaching Healthy Habits That Last
Children model what they see. If oral hygiene is a consistent, matter-of-fact part of daily family life — not a battle or an afterthought — children internalize it as normal. A few practical tips:
- Make brushing a shared family activity, especially when children are young
- Use a two-minute timer or a fun song to ensure adequate brushing time
- Talk about dental visits in a positive, neutral way — avoid language that introduces fear
- Limit sugary and acidic beverages, especially between meals
- Keep regular dental appointments — every six months for most children
