VK Pediatric Dentistry is an award-winning practice in Arlington led by two residency-trained pediatric dentists, Dr. Peter Markov and Dr. Allie Lonneman. We've been voted Best Pediatric Dentist by Arlington Magazine, Washingtonian, Northern Virginia Magazine, Washington Parent, and Washington Family, with 200+ five-star reviews from neighbors in Arlington, McLean, Falls Church, and DC. What actually sets us apart, though, is how we think about your child's mouth. We treat it as part of the whole child — connected to their airway, their breathing, their sleep, their feeding, their speech, and their growth and development — not just as a set of teeth to clean. That means our exams screen for things most dental offices don't look for (tongue posture, palate shape, bite development, mouth-breathing patterns), our treatment philosophy stays genuinely conservative (the least-invasive option that solves the problem), and our materials and imaging equipment are specifically chosen for children, not borrowed from adult dentistry. We're also a calm office, on purpose. Our team is trained in pediatric behavior guidance, and our space is built around helping kids feel comfortable: TVs in every room, stuffed animals, bubbles, toys, and a pace that doesn't rush. If you're trying to decide whether we're right for your family, we're happy to give you a free office tour — no appointment needed.

A pediatric dentist completes a 2–3 year hospital-based residency after dental school, focused exclusively on the dental care of infants, children, teens, and patients with special healthcare needs. It's the same kind of specialty residency a pediatrician completes for medicine — which is also why the American Academy of Pediatric Dentistry calls pediatric dentists "the pediatricians of dentistry." A general dentist who sees children has not completed that residency. In practice, that training means a few things you can't really see on a website: We're trained in child behavior and development, so we know what's normal at age 2 vs. age 6 vs. age 12, and how to actually help an anxious child through a visit instead of just trying to get them to sit still. We're trained in hospital-based pediatric dentistry — caring for medically complex kids, sedation training, and emergency management. We're trained to screen for things outside the teeth: airway and breathing patterns, tongue position and palate shape, bite and jaw development, growth and development, feeding and speech concerns, and habits that might be compensating for an underlying issue. Most general dentists don't look for any of this, because they were never trained to. Both of VK's dentists, Dr. Peter Markov and Dr. Allie Lonneman, are residency-trained pediatric specialists. Some general dentists do good work with kids — but if you have access to a pediatric specialist for your child's earliest, most formative dental years, that's the better move.

By their first birthday or the appearance of the first tooth, whichever comes first — consistent with American Academy of Pediatric Dentistry (AAPD) guidance. We see infants as young as 12 months and welcome first-time families anytime. A common misconception is that "they're just baby teeth" and the first visit can wait until age 3. The early visit isn't really about cleaning a few teeth, though — it's diagnostic. Establishing a dental home in your child's first year does prevent cavities (the most common chronic childhood disease), but because the mouth is also the gateway to the airway, breathing, and feeding, the early visit lets a pediatric dentist spot patterns that often get missed at well-child visits, including: Signs of acid reflux visible on the teeth Oral findings related to chronic constipation Snoring or mouth-breathing at night (airway concerns) Tooth grinding (bruxism) Whether habits like prolonged pacifier use are developmentally normal or compensating for an underlying issue Catching these early often means a simple conversation or small intervention now, instead of orthodontics, restorations, or specialist referrals later. The real value of the first-birthday visit isn't the cleaning — it's what we can prevent.

Something refreshing, honestly. We've built our office to feel calm — a modern, bright, spotless space with TVs in every room, stuffed animals, bubbles, and a small toy to take home at the end. Most kids who come in nervous warm up within the first few minutes, and parents are welcome in the treatment area for every visit. The visit itself usually includes an exam, x-rays if needed, and a cleaning — but the exam is the real heart of it, not the cleaning. One of our pediatric dentists (Dr. Peter Markov or Dr. Allie Lonneman) will sit with your child and screen for: Tooth count, eruption pattern, and cavity risk Bite and jaw development (early signs of crowding, crossbite, open bite) Tongue posture, palate shape, and frenum (tongue/lip-tie) Airway and breathing patterns — snoring, mouth-breathing, sleep quality Habits like thumb-sucking, pacifier use, or grinding, and whether they're developmentally normal or compensating for something underlying Speech and feeding milestones, where relevant Diet, snacking patterns, and home-care technique Then we'll sit down with you and walk through a treatment plan built specifically for your child. It's a real plan based on what we just saw. For one kid it might mean "see you in 6 months, you're doing everything right." For another it might mean a simple habit conversation now to prevent orthodontics later, a sealants discussion, or a referral to a speech-language pathologist or ENT for something we noticed on the screening. We never recommend treatment your child doesn't actually need, and we'll explain the reasoning behind anything we do suggest, in plain language you can take home and think about. Please remember to complete our patient forms and provide your insurance information at least 2 days before your appointment — we'll take it from there!

Every 6 months for most kids, per American Academy of Pediatric Dentistry guidance. Some kids need to be seen more often (high cavity risk, orthodontic monitoring, an airway concern under observation), and we'll tell you if that's the case. It's worth understanding why the 6-month cadence matters, because skipping visits is one of the most expensive mistakes families accidentally make. A few numbers we think parents should know: Tooth decay is the single most common chronic disease of childhood in the United States — more common than asthma, and largely preventable. About 1 in 4 children ages 2–5 already have cavities in their primary teeth, and by elementary school more than half of kids have had a cavity. Most of those were entirely preventable with consistent preventive care. A small cavity caught at a routine visit is often a 20-minute filling. The same cavity caught a year later can mean a crown, a pulpotomy ("baby root canal"), sedation, or all three — at a much higher cost, and a much harder visit for your child. But the 6-month visit isn't only about cavity-hunting. It's also how we monitor your child's growth and development over time — eruption patterns, bite changes, airway and breathing, palate shape, and habits. A single snapshot tells us much less than a series of snapshots taken at predictable intervals. That's how we catch things early, when a small conversation or a low-cost intervention can prevent something larger later.

Yes. We offer nitrous oxide ("laughing gas") for kids who need a little extra help to get through a visit, and we use a calm, behavior-first approach with every patient regardless of whether sedation is involved. One of the reasons for that is the things we do around the appointment matter more than people realize. A quick honest answer to what parents usually ask: Is nitrous safe? Nitrous oxide has been used in dentistry for over a hundred years and is one of the safest forms of sedation when administered by a trained pediatric team. It's mixed with oxygen (always more oxygen than nitrous), kids stay fully conscious and able to respond and converse the whole time, and the effect wears off within about 5 minutes once we switch them to pure oxygen at the end. There's no grogginess, no "off" feeling on the drive home, and they can go straight back to school or to lunch. What does it feel like? Most kids describe it as feeling "warm," "floaty," or just "kind of happy." They usually still feel everything that's happening — they just care a lot less about it. We tell kids it's "happy air" and let them pick the flavor of the mask scent. Does it knock them out? No. Nitrous is light sedation, not general anesthesia — your child stays awake and aware. If your child needs deeper sedation than that, we'll talk with you about appropriate options for their specific situation. The bigger point, though: a general dentist's office and a pediatric specialist's office can both technically offer nitrous, but the outcome a child has is usually very different. Pediatric residency training is largely behavior guidance — knowing how to introduce a new sensation to an anxious 4-year-old, how to pace a visit, how to use distraction (the TV on the ceiling, a stuffed animal in their hands, the right tone of voice) so the nitrous is supplementing a comfortable visit, not trying to rescue a difficult one.

Yes. We evaluate and, when appropriate, perform laser frenectomies for infants and children with tongue-ties (ankyloglossia) and lip-ties. Dr. Allie Lonneman has particular expertise in this area, and we built our approach around being both expertly trained and genuinely conservative — which matters, because tongue-tie is one of the most over-treated and under-treated diagnoses in pediatric care right now. Our position: not every tongue-tie needs to be released. The question isn't really whether a frenum looks tight — it's whether your child's function is being affected. We look at symptoms, not just anatomy: In infants: Difficulty latching during breastfeeding Painful or damaged nipples during nursing Clicking sounds while feeding, or milk leaking from the corners of the mouth Reflux symptoms, fussiness at the breast, or excessive gas Poor weight gain or very long feeding sessions Falling asleep before finishing a feed In toddlers and older kids: Speech sound errors (especially with L, R, S, T, D, and TH sounds) Picky eating or trouble with textured foods Mouth-breathing, snoring, or restless sleep A high or narrow palate (often visible from the outside as a long, narrow face) A gap between the top front teeth caused by a tight lip frenum Inability to lift the tongue to the roof of the mouth, or stick it past the lower lip We coordinate care with IBCLC lactation consultants, speech-language pathologists, myofunctional therapists and bodyworkers when needed — because a tongue-tie release without the right pre- and post-care often doesn't deliver the outcome a family is hoping for. The procedure itself, when indicated, takes only a few minutes with our soft-tissue Co2 laser (no scalpel, minimal bleeding, no general anesthesia). Most infants are back to feeding within minutes. If you're not sure whether your child has a functional tongue-tie, an evaluation is the right next step. We'll tell you honestly if treatment is the answer — or if it isn't.

Both of our pediatric dentists are residency-trained in caring for children with special healthcare needs, and our team and office are set up to accommodate a range of needs. Please let us know when you book so we can prepare the best visit for your child.

Most thumb-sucking and pacifier habits resolve on their own by ages 3, and gentle encouragement is enough for the majority of kids. But if your child is still going strong past 3 — or if you're seeing the front teeth flare forward, an "open bite" forming, or a narrowing palate — it's worth a closer look. Not because you need to crack down, but because why the habit is still there usually matters more than the habit itself. A thumb or pacifier past age 3 is rarely just a habit. It's almost always tied to a moment — being tired, being bored, being in front of a screen, being separated from a parent, or, less obviously, struggling to keep an airway open. Kids with poor nasal breathing often self-soothe with sucking, because the act of sucking holds the tongue forward and keeps the airway more patent. When we sit with parents, the most useful question is rarely "how do we stop this?" — it's "what's the trigger, and what need is the habit meeting?" Once we identify that, the strategy practically writes itself: replace the moment, not just the behavior. That might be a reward chart for a specific time of day, a comfort object that competes with the thumb, addressing nighttime mouth-breathing if that's the real driver, or a calm conversation with a 5-year-old about why their front teeth are starting to move (kids this age respond surprisingly well to being treated like decision-makers in their own care). Physical reminders — a soft thumb guard worn at night, for example — work well for kids who genuinely want to stop and just need help catching themselves. We rarely recommend a fixed dental appliance before age 6, and almost never as a first move. The piece a lot of articles or superficial advice skips: a stubborn thumb habit past age 3 is sometimes a sign that something else is going on — poor nasal breathing, an airway issue, or a tongue posture concern. Sucking keeps the tongue forward and helps hold the airway open, so kids unconsciously self-soothe with it. When that's what's actually driving the habit, sometimes the right intervention isn't a thumb guard — it's addressing the airway. That's exactly the kind of pattern we screen for at a routine visit.

Yes — but the right answer is a bit more interesting than yes, because not all "digital" x-ray equipment is equal, and we made some specific choices that meaningfully reduce your child's exposure compared to most pediatric dental offices. The short version: dental x-rays use very small amounts of radiation, we take them only when clinically indicated (we follow the ADA and AAPD "as low as reasonably achievable" guidelines), and the diagnostic benefit far outweighs the negligible risk when used appropriately. We don't take routine x-rays "because it's been 6 months" — we take them when a child's specific cavity risk, history, or exam findings call for them. The longer answer is where the equipment matters. We use a VATECH panoramic system and a NOMAD handheld x-ray — both specifically chosen because they produce among the lowest doses available in dentistry today. To put real numbers around it: A single bitewing x-ray on our digital sensors delivers roughly 0.005 mSv of radiation. For comparison: a child gets about 0.008–0.01 mSv every single day from natural background radiation just by existing on Earth. So one of our bitewings is about half of one day of normal background exposure. A medical CT scan can range from 5–10 mSv — equivalent to 1,000 or more of our bitewings. Our position: when an x-ray is genuinely needed, the diagnostic information it gives us is worth far more than the negligible exposure. When it isn't needed, we don't take one. We chose this equipment because we believe "low dose" should mean low dose, not a marketing phrase.

We ask that you arrive about 5 minutes early. If you're running late, please call as soon as you can — we'll do our best to accommodate, but appointments more than 10 minutes late may need to be rescheduled and a late fee may apply. For cancellations, we ask for 48 hours' notice so we can offer your time to another family. Multiple missed appointments may result in dismissal as a patient.

Yes — always. Parents are welcome in the treatment area for every visit at every age. Some pediatric practices prefer to separate parents and kids during treatment, and there are reasonable arguments for it (some kids behave better without a parent as an audience). We respect that approach, but it's not ours. A few reasons: You see what we're doing and why. You're hearing about your child's mouth in real time — what the cavity looks like, why we chose the material we did, what the bite is doing. That's the most efficient parent education there is. No telephone game, no second-hand summary, no "wait, what was the recommendation again?" You can practice the technique we teach at home. Toothbrushing and Flossing for kids is genuinely hard to get right, and watching us demonstrate the angle, pressure, and pattern on your child's actual teeth is much more useful than hearing about it later. Hard conversations are easier in real time. If we're recommending treatment, sedation, a specialist referral, or a habit conversation, we'd rather have that conversation with you face-to-face in the room than have your child summarize it for you in the car. Our waiting room is genuinely nice if you'd rather take a few minutes for yourself during a routine cleaning, and we won't judge that either.
