Children’s Dentist in Locust Valley



children's dentist through adulthood at locust valley dentists new york

Contrary to what you might think, baby teeth need to be taken care of just as intentionally as so-called “adult” teeth. It’s estimated that one in five children under the age of five has some degree of tooth decay, which can cause problems even after the affected tooth falls out. This is why finding a qualified, experienced child’s dentist is so important, from the earliest age possible.

    Dental Care from Childhood to Adulthood

    Our approach to children’s dentistry emphasizes different stages of physical, emotional, and mental growth. We aim to help provide your child with exactly what they need as they travel through life’s journey. We help children with:

    • Exams and checkups by our gentle dentists and staff
    • Preventing cavities — important even before “adult” teeth appear
    • Developing great brushing habits (with the help of their parents)
    • Minimizing dental anxiety, a key to lifelong dental health
    • Developing control for their own dental health as they become teenagers and enter adulthood

      What is Pediatric Dentistry?

      Pediatric dentists in Locust Valley are educated and trained to care for infants and children through adolescence. They use skilled techniques to influence behavior and employ numerous treatments to keep young kids’ teeth healthy and strong, transitioning them into young adulthood.

      Treatments used in pediatric dentistry include regular cleanings (even with baby teeth), fluoride treatments, orthodontics, and dental sealants.

      What Age Should Parents Start Bringing Their Child to the Dentist?

      The rule of thumb is that once you see a tooth in your baby’s mouth, it’s time to see a pediatric dentist. Be sure to schedule an appointment at some point before they turn one. As soon as teeth erupt, they should be cleaned regularly by the parents, and when two teeth erupt next to each other, you’ll need to start flossing as well. These tasks can be turned over to the child when they are able to accomplish them by themselves, usually before the age of six.

      How Should Parents Prepare Their Child for the First Visit?

      Parents can help their infants prepare for a visit to the dentist by modeling what things Dr. Koster may do in the visit, such as opening the mouth for inspection or moving a gloved finger or dental tool around the mouth, while sitting in a chair or on a parent’s lap.

      Employing a gum cleaning routine and teething toys early on can also help newborns adapt to their first dentist visit. After eating or breastfeeding, wipe down your baby’s gums with a cloth or gauze to help keep your child’s mouth healthy and free of bacteria.

      You can minimize the amount of time you spend in the waiting room, which can be an unpleasant experience for some babies, by filling out the new patient forms online ahead of your visit.

      What Happens at the First Dental Visit?

      At your baby’s first visit to Locust Valley Dentists, you’ll bring your child into a dental examination room and have them sit either on our dental chair or in your lap, whichever they’re more comfortable with. Dr. Koster will then examine their mouth, looking at any teeth that have erupted, checking the gums, bite, and frenum for any issues, and cleaning the teeth and gums.

      Dr. Koster will also provide comprehensive information and recommendations for how to manage your baby’s oral health at home and answer any questions you may have — as many as you have! Finally, she’ll schedule your next appointment, usually around the six-month mark.

      Do Children See the Dentists as Frequently as Teens & Adults?

      In short, yes. The many growth stages that happen in children’s mouths from infancy to adolescence are important to monitor for infection, decay, or injuries. Children can get nearly any mouth disease that adults can, including gum disease, cavities, and poor dental hygiene. In addition, children are at risk for early childhood caries, a condition in which children develop two cavities before the age of six — cavities in baby teeth.

      Kids of all ages should brush their teeth twice a day with fluoride toothpaste and floss correctly to remove food particles and plaque from between teeth. Although many things are different between children, teens, and adults, oral hygiene is not one of them.

      Pediatric Dentistry FAQs

      Do Pediatric dentists see adults?

      Many dentists, including Dr. Koster, see both children and adults. Some dentists see only pediatric patients.

      Do toddlers need dental insurance?

      Toddlers can be covered by dental insurance plans because it is important for children to begin seeing a dentist at an early age.

      Does my child need a pediatric dentist?

      For children, parents can choose between a pediatric dentist or a family dentist. Pediatric dentists only see young patients, while a family dentist can treat patients of any age, including children. Some parents find it more convenient to choose one dentist who can treat their whole family.

      How often do you take toddler to dentist?

      Toddlers should generally see the dentist every six months.

      What happens at your childs first dentist appointment?

      A child’s first dental appointment involves a full exam of the teeth, jaws, oral tissues, gums, and bite. Your child’s dentist will check in on their overall dental health and development and may also perform a professional cleaning.

      What is the difference between a general dentist and a pediatric dentist?

      A general dentist treats patients at all ages regarding their oral health, while a pediatric dentist specializes in treating infants or children.

      What skills do you need for dentistry?

      Dentists should be knowledgeable and interested in science, have good eyesight and manual dexterity, and possess good communication skills.

      What skills do you need to be a pediatric dentist?

      Pediatric dentists should have good interpersonal skills, good communication skills, compassion, and a thorough understanding and interest in science.

      Why is pediatric dentistry important?

      Pediatric dentistry is important to help children develop good oral hygiene habits early, prevent cavities or other issues before they arise, and check in on children’s development.
