Children’s Dentistry in New York City
Kid-friendly dental care that builds healthy habits and ensures growing smiles stay strong, clean, and cavity-free.
Gentle, Preventive Care to Help Your Child Smile with Confidence
Early dental care lays the foundation for a lifetime of healthy smiles. At Teeth By Keith, we specialize in children’s dentistry in NYC with a compassionate, educational approach that helps young patients feel comfortable, confident, and understood — from their very first visit.
Led by Dr. Keith R. Marshall, DDS, a general dentist with over 40 years of experience, our Manhattan practice welcomes patients ages 14 and up. We understand the unique oral health needs of teens and older children and how to keep them engaged in their dental wellness as they grow.
Creating a Positive Dental Experience for Kids & Teens
Dental anxiety is common, especially among children and adolescents. That’s why we’ve designed our East 32nd Street office to feel calm, relaxed, and welcoming. Dr. Keith’s warm chairside manner and decades of experience with young patients help turn dental visits into positive habits, not fearful events.
We focus on prevention and education, giving kids the tools they need to care for their smiles and build confidence around dental health.
What’s Included in a Child’s Visit
Every child’s appointment is tailored to their age, dental development, and comfort level. Services may include:
Gentle Dental Cleanings
We remove plaque and tartar from hard-to-reach places, helping to prevent cavities and gum inflammation, especially during orthodontic treatment or sports seasons.
Learn more about our preventive care approach on the Cleanings & Maintenance page.
Comprehensive Exams
Dr. Keith evaluates each tooth, the gums, bite alignment, and growth patterns to catch any issues early. For new patients, this may include digital X-rays or Cone Beam 3D Imaging for more complex cases like impacted teeth or orthodontic planning.
Explore Comprehensive Exams to understand what we evaluate during routine checkups.
Fluoride Treatments
For cavity-prone teens or kids with early enamel weakness, we may recommend a fluoride application to strengthen teeth and reduce decay risk.
Custom Mouthguards
For young athletes, we provide custom-fitted mouthguards to protect teeth from sports-related injuries — a valuable part of total dental maintenance.
Night Guard Consults for Teen Bruxism
Some adolescents grind their teeth at night due to stress, orthodontic changes, or sleep issues. We offer night guards to reduce wear and protect long-term bite health.
When to Bring Your Child to the Dentist
We welcome teens and pre-teens, typically ages 14 and older, for general and preventive care. The ideal time to bring your child for their first visit with us is:
- When they’ve transitioned to a full adult dentition
- When they’ve completed orthodontic care
- When they’re ready for personalized hygiene instruction or bite evaluation
- If they’ve experienced trauma, pain, or sensitivity
We focus on guiding adolescents through this transitional stage with proactive care and trusted, age-appropriate treatment.
