Warning
General information only - not dental advice. This guide provides general educational information about children's dental health. It is not a diagnosis, treatment recommendation, or substitute for professional dental or medical advice. Every child's situation is different. Always consult a licensed dentist or pediatric dentist before making decisions about your child's oral health or treatment.
Children's dental health lays the groundwork for a lifetime of oral health, according to the American Academy of Pediatric Dentistry (AAPD). Habits and structures established in early childhood -- from the timing of the first dental visit to daily brushing routines -- influence cavity rates, jaw development, and comfort with dental care well into adulthood. This guide covers what parents most commonly want to know: when to start, what to expect, and how to set children up for genuinely healthy teeth. It is not a substitute for the individualized guidance a dentist who has examined your child can provide.
When Should a Child Have Their First Dental Visit?
The AAPD recommends a child's first dental visit within six months of the first tooth erupting, and no later than the child's first birthday. This recommendation surprises many parents, who assume dental visits can wait until the child has a full set of teeth or is old enough to cooperate with an exam.
The reasons for starting early are practical. A dentist can identify early-childhood caries (tooth decay in infants and toddlers), assess how the teeth are erupting, and discuss habits that affect oral health -- including bottle feeding, pacifier use, and thumb-sucking. The AAPD notes that tooth decay is the most common chronic childhood disease in the United States, according to CDC children's oral health data, and that it is largely preventable with early intervention.
The first visit is also about establishing what the AAPD calls a "dental home" -- a consistent relationship with a provider who knows the child's history. Children who have a dental home from an early age are more likely to receive preventive care and less likely to need emergency treatment, according to AAPD policy statements.
CDC data on children's oral health note that untreated tooth decay affects approximately 13 percent of children aged 5 to 19, contributing to missed school days and difficulty eating.

What Is a Pediatric Dentist and Do You Need One?
A pediatric dentist is a dental specialist who completes dental school followed by a two to three-year residency focused specifically on treating infants, children, and adolescents, including those with special health care needs, according to the AAPD. The residency covers child behavior management, growth and development, and the management of dental problems specific to younger patients.
Whether your child needs a pediatric dentist versus a general dentist depends on several factors. Many general dentists provide excellent care for children and are a practical choice, particularly in areas with limited access to pediatric specialists or for families whose general dentist has a long-established relationship with the child. For children with significant dental anxiety, complex dental needs, or special health care needs, a pediatric dental office -- which is designed with a child-centered environment and staffed by providers trained in child behavior techniques -- may be a better fit.
The American Dental Association notes that the most important factor is that children have a consistent dental provider they see regularly, regardless of specialty designation.
Why Baby Teeth Matter
A common misconception is that baby teeth (primary teeth) do not require the same attention as permanent teeth because they fall out anyway. The AAPD strongly emphasizes that primary teeth serve essential functions that directly affect a child's development.
Baby teeth hold space for the permanent teeth developing beneath them. When a primary tooth is lost prematurely due to decay or injury, neighboring teeth can drift into the gap, crowding the space that the permanent tooth needs. This can contribute to orthodontic problems that require later correction.
Primary teeth also support speech development, chewing, and nutrition -- children with significant early tooth decay may have difficulty eating and speaking normally. According to CDC children's oral health statistics, early childhood caries is the most common chronic disease in children aged 5 to 11, and it can cause pain and infection that affect school performance and quality of life.
The NIDCR (National Institute of Dental and Craniofacial Research) notes that decay in baby teeth -- called early childhood caries -- can progress rapidly and is associated with pain and infection if untreated. Treatment for extensive decay in young children sometimes requires sedation or general anesthesia, which makes prevention far preferable.
Preventive Treatments for Children: Sealants and Fluoride
Two preventive treatments are widely recommended for school-age children by both the American Dental Association and the AAPD: dental sealants and fluoride applications.
Dental sealants. Sealants are thin protective coatings applied to the grooves of back teeth -- particularly the permanent first molars, which erupt around age six. The grooves on these teeth are narrow enough that toothbrush bristles cannot fully clean them, making them common sites for cavities. The CDC and ADA both cite sealants as a proven preventive measure. CDC school sealant program data show that children without sealants are approximately three times more likely to develop first molar cavities than those with sealants.
For a detailed look at sealant procedure, cost, and insurance coverage, see our guide on dental sealants for kids.
Professional fluoride applications. Fluoride varnish or gel applied by a dental professional provides topical fluoride at a higher concentration than fluoride toothpaste. The NIDCR and ADA both support professional fluoride applications for children, particularly those at elevated cavity risk. Many insurance plans cover fluoride treatments for children at routine checkup intervals.
How to Teach Kids to Brush and Floss
The ADA's recommendations for children's oral hygiene are straightforward, though implementation requires consistent parental involvement in early years.
For children under three, the ADA recommends brushing with a grain-of-rice-sized smear of fluoride toothpaste twice daily. Between ages three and six, a pea-sized amount is appropriate. Parents should brush for their children until the child develops sufficient hand coordination to brush effectively on their own -- typically around age six to eight, though this varies. Even then, parental supervision and periodic checking is beneficial.
Flossing should begin as soon as two teeth touch side by side. For young children, floss picks can be easier to use than traditional string floss. Daily flossing cleans the surfaces between teeth that brushing cannot reach and is where approximately 35 percent of tooth surfaces are located, according to ADA patient education materials.
For guidance on correct flossing technique for adults and older children, our guide on how to prevent cavities covers the fundamentals of evidence-based oral hygiene.
Common Dental Issues in Children
Several dental issues are common in children, and many are manageable with early attention.
Early childhood caries (ECC). Prolonged bottle use with milk or juice at bedtime, frequent snacking on sugary foods, and poor brushing are the primary behavioral drivers, according to NIDCR data. Treatment ranges from fluoride application for very early decay to fillings, crowns, or extraction for more advanced cases.
Tooth eruption discomfort. Some children experience temporary gum discomfort when teeth erupt. This is normal and does not require dental treatment. However, if a tooth appears to be significantly delayed in erupting, or if there is swelling or pain beyond mild discomfort, an evaluation is appropriate.
Thumb-sucking and pacifier use. The AAPD notes that most children stop these habits on their own by age three or four. Habits that persist significantly beyond age four may affect the alignment of incoming permanent teeth and may warrant discussion with a dentist.
Dental trauma. Toddlers and young children fall frequently, and dental injuries are common. If a primary tooth is knocked out, it is typically not replanted (unlike a permanent tooth). If a permanent tooth is knocked out in an older child, urgent dental attention is needed -- time matters significantly for replantation success. Our guide on how often to see a dentist covers when to treat routine vs. urgent dental concerns.
How Much Does a Pediatric Dental Visit Cost?
A routine checkup and cleaning for a child at a pediatric or general dental office involves an examination, dental cleaning, and -- at some visits -- bitewing X-rays. Fees vary by geographic market and provider.
The American Dental Association's fee surveys indicate that routine examination and prophylaxis (cleaning) fees for children generally fall in a similar range to adult cleaning fees, though pediatric offices may include behavior management time in their base fee. In many markets, a routine child checkup with cleaning runs approximately $80 to $200 depending on whether X-rays are included and the local fee level.
Insurance coverage. Most dental insurance plans cover preventive care for children (cleanings, fluoride, sealants, X-rays) at 100 percent of the allowed fee with no deductible, as these are classified as preventive services, according to Delta Dental coverage guides. Restorative care (fillings, crowns) is typically covered at a lower percentage -- often 70 to 80 percent for basic services.
CHIP and Medicaid. For families who qualify, CHIP and Medicaid cover children's dental care as a mandatory benefit. Coverage includes diagnostic services, preventive care, and restorative treatment. Eligibility and benefit details vary by state. For more on public program dental coverage, see our guide on Medicaid dental coverage for adults, which also covers CHIP for children.
Always verify coverage with your specific plan or state program -- benefit details vary.
Warning
Talk to your child's dentist. This guide describes general patterns based on AAPD, ADA, CDC, and NIDCR guidance. It cannot address your child's specific dental development, cavity risk, or treatment needs. Only a dentist who has examined your child can provide guidance tailored to their situation. If your child has not yet had a first dental visit and is past their first birthday, scheduling one is a reasonable next step.
Frequently asked questions
At what age should a child first see a dentist?
The American Academy of Pediatric Dentistry recommends that a child's first dental visit occur within six months of the first tooth erupting, and no later than the child's first birthday. This early visit is primarily informational -- the dentist examines the mouth, discusses feeding and hygiene habits with the parent, and establishes a dental home for the child.
Are pediatric dentists more expensive than regular dentists?
Pediatric dentists complete two to three additional years of residency training focused exclusively on treating infants through teenagers, according to the American Academy of Pediatric Dentistry. Their fees may be somewhat higher than a general dentist's for the same procedure, but general dentists also treat children. Cost depends on the practice, location, and your insurance network.
What are dental sealants and are they worth it for kids?
Dental sealants are thin protective coatings applied to the chewing surfaces of back teeth (molars) to prevent bacteria from collecting in grooves. CDC data show that school-age children without sealants are almost three times more likely to have first molar cavities than children with sealants. Most dental insurance plans cover sealants for children on primary and permanent molars.
How do I help a child who is afraid of the dentist?
The American Academy of Pediatric Dentistry notes that early, positive visits before any treatment is needed are the most effective way to build a child's comfort with dental care. Framing visits as routine and normal, avoiding language that connects the dentist with pain, and choosing a child-friendly practice are practical steps. Some children benefit from a meeting-the-dentist visit before any procedures.
When do children need X-rays at the dentist?
The American Dental Association recommends that X-ray frequency be based on each child's individual cavity risk, not a fixed schedule. Children with higher risk (poor hygiene, diet high in sugar, history of cavities) may need bitewing X-rays every six to twelve months. Lower-risk children may need them less frequently. Your child's dentist determines frequency based on a risk assessment.
Does CHIP or Medicaid cover children's dental care?
Yes. The Children's Health Insurance Program (CHIP) and Medicaid both cover dental services for eligible children as a mandatory benefit under federal law. The benefits typically include diagnostic services, preventive care (cleanings, fluoride, sealants), and restorative treatment. Coverage details vary by state. Benefits.gov and your state Medicaid office are authoritative sources for eligibility.
