Frequently Asked Questions
What is a pediatric dentist?
A pediatric dentist is a specialist dedicated to the oral health of children, from infancy through the teen years. After dental school, pediatric dentists complete additional years of training focused on child development, behavior guidance, and the dental needs of growing mouths, including children with special healthcare needs.
They also work alongside pediatricians to support a child’s overall health. In short, a pediatric dentist is trained specifically to care for kids, in an environment built to make them feel comfortable.
Why are baby teeth important if they eventually fall out?
Healthy baby teeth set the foundation for everything that follows. They are essential for proper chewing and nutrition, they support clear speech development, and they hold space so permanent teeth can erupt in the right position. Neglected baby teeth can lead to pain, infection, and problems for the developing adult teeth underneath. Caring for baby teeth also builds the habits and confidence your child will carry for life.
Are dental X-rays safe for my child?
Yes. We follow the guidelines of the American Academy of Pediatric Dentistry and the American Dental Association, and we use digital X-rays, which significantly lower radiation, along with proper protection such as thyroid collars. Digital X-rays can reduce exposure by up to 80 percent compared with older film. We also take X-rays only when they are needed, based on your child’s individual risk factors, rather than on a fixed schedule.
Is fluoride safe for my child?
Yes, when used in the appropriate amounts, fluoride is safe and is the single most effective way to prevent cavities. It is found in tap water, toothpaste, and some foods, and it is recommended by all major dental associations.
We are always glad to talk through any concerns and help you use the right amount for your child’s age. Prevention is at the heart of pediatric dentistry, and fluoride is one of our most reliable tools.
Can my child's cavities be treated the same day as the first exam?
Usually we do not provide treatment at the very first visit. Two things matter most to us: your child’s overall experience and the quality of their care. For many children, that means returning on a separate day, when they are fresh and we can dedicate focused time to treatment. That said, we respect your family’s time, and there are situations where same-day care is possible. We will always discuss the plan with you.
What if my child is very scared, or had a bad dental experience before?
This is one of the most common concerns we hear, and we are well prepared for it. A different office, a different team, and a gentle, patient approach make a real difference for anxious children. We use proven, child-friendly techniques to build trust and comfort, and we move at your child’s pace. Many parents are pleasantly surprised at how calm a previously fearful child can become.
What can I do at home to help prevent cavities?
Prevention starts with daily habits. For infants, gently wipe the gums and teeth with a soft cloth after feedings, and never put your child to bed with a bottle of anything but water. For toddlers and young children, help them brush twice a day and floss daily, since the fine motor skills for solo brushing usually do not develop until age seven or eight.
Choose healthy snacks, limit sugary drinks, and keep up with regular checkups every six months. Many children also do well with an electric toothbrush, just ask us when to start.
What are dental sealants?
A sealant is a thin, protective resin coating applied to the chewing surfaces of the back teeth, where most cavities form. Sealants act as a barrier against food, plaque, and acid in the deep grooves that brushing can miss.
They are most effective when applied soon after the molars come in, usually around age six or seven. Sealants do not protect the spaces between teeth, so daily brushing and flossing are still important.
Up to what age do you treat patients?
We care for children at every stage, from a baby’s first visit around age one all the way through the teen years. Pediatric dentistry is designed to grow with your child, supporting their changing needs from infancy through adolescence, including early orthodontic and airway-focused care along the way.
Do you offer sedation for anxious children?
Yes. For children who feel very anxious or need more involved treatment, we offer gentle, carefully monitored options, including nitrous oxide (laughing gas) and oral sedation, and we coordinate with pediatric anesthesia professionals for more complex needs. We recommend sedation only when it is truly appropriate, with safety first. You can read more on our sedation dentistry page.
What is the difference between a pediatric dentist and an orthodontist?
They are different specialties with different focuses. A pediatric dentist is the dental specialist for children overall, handling cleanings, cavities, prevention, growth monitoring, and the everyday oral health of kids from infancy through the teen years. An orthodontist focuses specifically on aligning teeth and jaws, usually with braces or aligners, typically in the older child and teen years.
As a pediatric practice, we provide complete children’s dental care and early, growth-guided orthodontic treatment such as Phase 1 care and palatal expanders, and we coordinate with an orthodontic specialist when full braces are the right next step.
At what age can my child brush their own teeth?
Most children do not have the fine motor skills to clean their teeth thoroughly on their own until about age seven or eight. Until then, let your child practice for independence and confidence, then follow up and brush again yourself to be sure every surface is clean. A good rule of thumb is that if your child can write in cursive, they likely have the dexterity to brush well. We are always glad to demonstrate good technique at your child’s visit.
