Crowded Teeth
Crowding occurs when there is not enough room in the dental arch for teeth to align normally.
Personalized orthodontic care for children, teens, and adults at Tribeca Dental Studio. Explore traditional braces, lingual braces, Invisalign® clear aligners, airway-focused orthodontics, and individualized treatment planning in Lower Manhattan.
Treatment is planned around your teeth, bite, facial development, oral health, lifestyle, and long-term stability rather than a one-size-fits-all approach.

Board-Certified Orthodontic Care
Orthodontic diagnosis and treatment planning in the heart of Tribeca.
Orthodontics isn't just for teenagers anymore — we treat kids, teens, and plenty of adults. The right option depends on your teeth, your bite, and your life: traditional braces for precise control, lingual braces hidden behind the teeth, or Invisalign for something removable. It all starts with a proper diagnosis from our board-certified orthodontist.
Dr. Reem Abdulrahman is an American Board-certified orthodontist with advanced training in Orthodontics and Craniofacial Orthopedics.
She completed a three-year Orthodontics and Craniofacial Orthopedics residency at Albert Einstein Medical Center in Philadelphia after previous training and clinical experience in general dentistry.

Different orthodontic systems solve different problems. Your treatment plan should be based on the movements your teeth require, your bite, oral health, growth and development, lifestyle, and personal preferences.
Fixed metal or ceramic brackets provide precise control over tooth movement and can be used for a wide range of alignment and bite concerns.
Explore TreatmentLingual braces are attached behind the teeth, providing fixed orthodontic treatment while making the appliance much less visible from the front.
Explore TreatmentA series of removable clear aligners gradually moves teeth according to a digitally planned sequence. Aligners may be appropriate for selected alignment and bite concerns.
Explore TreatmentAirway-focused orthodontic evaluation considers jaw development, dental arch width, breathing patterns, and other structural factors alongside tooth alignment.
Explore Treatment| Option | How It Works |
|---|---|
| Traditional Braces | Fixed brackets with precise control for a wide range of concerns |
| Lingual Braces | Fixed behind the teeth — much less visible from the front |
| Invisalign® Clear Aligners | Removable trays moved through a digitally planned sequence |
| Airway Orthodontics | Considers jaw development and breathing alongside alignment |
Orthodontic evaluation looks at both tooth alignment and how the upper and lower teeth function together.
Crowding occurs when there is not enough room in the dental arch for teeth to align normally.
Orthodontic treatment can help manage unwanted spaces between teeth when tooth movement is clinically appropriate.
An excessive vertical overlap between the upper and lower front teeth may benefit from orthodontic evaluation.
An underbite occurs when the lower teeth or jaw sit ahead of the upper teeth when the mouth closes.
A crossbite occurs when some upper teeth bite inside the lower teeth rather than outside them.
With an open bite, some upper and lower teeth do not meet when the jaws close.
Orthodontic needs change throughout life. Treatment timing and appliance selection should reflect dental development, growth, oral health, and individual goals.
An early orthodontic evaluation can identify concerns involving tooth eruption, crowding, bite development, arch width, and jaw growth. Early evaluation does not necessarily mean immediate treatment.
Teen orthodontic treatment may use fixed braces or removable aligners depending on the bite, tooth movement required, maturity, and ability to follow treatment instructions.
Adults can benefit from orthodontic treatment as long as the teeth and supporting tissues are healthy enough for movement. Discreet options such as lingual braces and clear aligners may be considered when appropriate.
We review your concerns, dental history, tooth alignment, bite relationships, and overall oral health.
Digital scans, photographs, and appropriate imaging may be used to understand tooth position and supporting structures.
Your orthodontist reviews the available options and recommends an approach based on the movements required, treatment goals, and individual anatomy.
Progress is monitored during regular visits, and appliances or aligners are adjusted according to your treatment plan.
After active tooth movement is complete, retainers help maintain the new tooth positions over time.
There is no single orthodontic appliance that is automatically best for every patient. The right choice depends on the movements required and how the treatment fits your needs.
| Feature | Fixed Braces | Invisalign® |
|---|---|---|
| Removable | No | Yes |
| Visibility | Varies by system; lingual braces sit behind the teeth | Clear and discreet |
| Patient Compliance | Fixed in place | Must be worn as prescribed |
| Best Choice | Depends on treatment needs | Depends on treatment needs |
Modern orthodontic planning may combine digital scans, photographs, radiographic imaging, and other diagnostic records to evaluate tooth position, bite relationships, available space, and supporting anatomy.
The diagnostic tools used depend on the individual case. The goal is to plan treatment based on measurable clinical information rather than appearance alone.

Finishing active orthodontic treatment does not mean the process is over. Teeth can shift over time, which is why retention is an important part of maintaining your new alignment.
Your orthodontist will recommend the type of retainer and wear schedule appropriate for your individual treatment.

What actually determines the cost of braces: case complexity, the appliance that fits your bite, treatment length, and the insurance questions to ask first.
For a child who needs braces or an adult ready to straighten their own teeth, the first step is the same: a full orthodontic evaluation built from your bite, not a template.
Tribeca Dental Studio offers several orthodontic approaches, including traditional braces, lingual braces, Invisalign® clear aligners, and airway-focused orthodontic evaluation. The appropriate option depends on your teeth, bite, oral health, age, and treatment goals.

Yes. Adults can undergo orthodontic treatment when their teeth, gums, and supporting structures are healthy enough for tooth movement. The appropriate appliance depends on the movements required and your individual treatment needs.
Neither option is automatically better for every patient. Fixed braces provide continuous tooth movement, while Invisalign uses removable clear aligners. Your orthodontist can recommend an option based on the complexity of the movements required, bite relationships, lifestyle, and treatment goals.
Treatment time varies considerably. It depends on the amount and type of tooth movement required, bite correction, appliance type, growth, biological response, and treatment goals. An individualized estimate can be provided after diagnostic evaluation.
An orthodontic evaluation may be recommended when there are concerns about crowding, bite development, jaw growth, tooth eruption, spacing, or other developmental issues. The timing of treatment is individualized and an early evaluation does not always mean treatment must begin immediately.
Retention is an important part of orthodontic care. Retainers help maintain tooth positions after active treatment. Your orthodontist will recommend the type and wear schedule appropriate for your case.

Orthodontics is the planning of tooth movement — not just making teeth look straight, but positioning every tooth where it functions best: meeting its opposite number cleanly, sharing bite forces evenly, and leaving spaces that can actually be cleaned. A consultation here begins with records, not with an appliance.
We study the alignment, the bite relationship between the jaws, the health of the gums and bone that teeth will move through, and — for younger patients — how much growth remains to work with. The plan we write follows from those records, which is why two patients with similar-looking smiles can receive very different recommendations.
Choosing between braces and clear aligners is a mechanical decision before it is a cosmetic one. Fixed braces give the orthodontist direct control over rotations, root angles, and vertical positions, and they work twenty-four hours a day whether you remember them or not. Aligners trade some of that control for removability and discretion, and they depend entirely on wear — a plan that assumes twenty-two hours a day fails quietly at twelve.
Some cases clearly suit one system; many sit in between, and a few are best treated with a combination. We will show you, for your specific movements, what each system does well and where it struggles, and our recommendation will follow the mechanics, not the marketing.
Treatment length is set by biology, not by the calendar we would prefer. Teeth move as bone remodels around them, and forcing the pace risks the roots and the bone rather than rewarding you with a faster finish. What we can control is efficiency: a plan sequenced so movements happen together instead of in series, appointments set at intervals that match the mechanics, and problems — a broken bracket, a tray that stops tracking — caught at reviews before they cost a month.
Your written plan will give an honest range for your case rather than a single optimistic number, and we will tell you at each stage whether you are on it.
Adults considering orthodontics usually carry one of three histories: treatment as a teenager whose result drifted because retainers were abandoned, crowding that has slowly worsened with age, or a bite problem that now complicates other dental work. All three are workable.
Adult treatment is planned around what is already in the mouth — crowns, implants that cannot move and must be planned around, gum health that needs stabilizing first — and coordinated with the rest of your care under one roof, so implant positions, restorative plans, and tooth movement are designed together instead of colliding later.
For children and teens, timing is a clinical decision with a closing window. Some problems are best corrected while growth can be guided — a narrow palate, a developing crossbite, a jaw relationship that is drifting off track — and interceptive treatment at the right moment can simplify or even prevent a harder correction later. Other children should simply be monitored until the permanent teeth arrive.
An early evaluation costs one visit and buys certainty about which situation your child is in; we will never sell you early treatment whose only benefit is starting early, and we will put 'monitor and review' in writing when that is the right prescription.
Comfort and daily life deserve straight talk. Braces involve an adjustment period after fittings and tightenings, a short list of foods to avoid, and cleaning that takes a few extra minutes and a few new tools, which we teach in person rather than describe on a handout. Aligners remove the food rules but add the discipline of wear and the routine of removing trays before meals and cleaning them properly. Neither is effortless.
Both are entirely manageable for the patients who choose them with open eyes, which is why the consultation covers the daily reality of each system in detail.
The finish matters as much as the movement. Teeth are settled into their final positions with detailed finishing bends or refinement aligners, the bite is checked tooth by tooth, and then retention begins — retainers fitted to hold the result while the bone and fibers around the teeth complete their remodeling.
Retention is part of the treatment plan from day one, with clear instructions and review appointments, because we judge our orthodontics by how your teeth look and function years later. If you are weighing treatment for yourself or your child, bring your questions to a consultation: we will answer them against your own records and put the recommendation, the sequence, and the expected timeline in writing.
Early evaluation does not always mean early treatment. Some children benefit from interceptive treatment while growth is available — guiding jaw development, making room for erupting teeth, correcting crossbites before they become asymmetries. Many others are better served by monitoring, letting baby teeth finish their work, and planning one efficient course of treatment in the early teens.
The evaluation separates the two situations, and if the right prescription is 'wait and watch,' that is what we will write down. What matters is that the growth window is assessed while it is still open, because options that exist at eight may not exist at fourteen.
Movement itself can be completed in a similar span either way; the difference is in what each system asks of your daily life and what movements it controls best. Braces work around the clock and ask only that you keep appointments and clean carefully. Aligners ask for near-constant wear and discipline at meals but come out for eating, photos, and presentations.
Some movements — large rotations, vertical corrections, complex root positioning — are handled more directly by fixed appliances. At your consultation we will map your case's specific movements and recommend the system that controls them best for the life you actually live, not the one that photographs best.
Retention is not the optional extra it is sometimes treated as — it is the phase that keeps your result. Teeth sit in bone that remodels around their new positions, and the fibers that hold them remember where they used to be. Retainers hold the result while that settling completes, full-time at first and then typically at night, and skipping them is how well-treated cases drift.
Your plan includes retention from the start — which retainers, how they are worn, and how we check them at reviews — because an orthodontic result should be measured years later, not on the day the braces come off.
Often, yes — adult orthodontics is a large part of what we do, and the motivations are usually practical: a bite that wears teeth unevenly, crowding that traps plaque, teeth that drifted after childhood treatment because retention lapsed, or preparation for restorations and implants that need teeth in the right positions first.
Adult bone responds to orthodontic force differently than a teenager's, and treatment is planned around existing restorations, gum health, and any missing teeth. None of that disqualifies you. An evaluation will map your specific mouth — not a generic one — and tell you honestly what movement is achievable and what it would take.
Every treatment at Tribeca Dental Studio starts with a diagnosis, not a sales pitch. Before we recommend anything, we examine the tooth or area in question, review imaging taken here in the office, and talk through what we see in plain language. You will always know what we recommend, why we recommend it, and what could safely wait.
That recommendation becomes a written plan, so the sequence, the timing, and the reasoning are clear before any treatment begins — and if a simpler option would serve you just as well, that is the option we will put in front of you.
Our studio brings every dental specialty under one roof at 54 Warren St in Tribeca, and it has since 2007. General dentistry, cosmetic care, implant surgery, periodontics, endodontics, orthodontics, airway care, and pediatric dentistry are handled by one team in one place, which means a treatment that touches several specialties is planned as a whole rather than handed off between offices across town.
Your records, your imaging, and your history stay with the same team from the first visit through every follow-up, so nothing is lost between providers and no step is planned in isolation.
We are open Monday to Friday from 8:00 AM to 6:00 PM, Saturday from 9:00 AM to 4:00 PM, and Sunday from 9:00 AM to 2:00 PM. You can book online at any time or call us at (212) 561-5303.
The studio sits between Greenwich Street and West Broadway, steps from the Chambers Street subway hub (1, 2, 3, A, C, E), with attended garages on Warren Street and Greenwich Street within a block of our door for patients who drive in.
Care does not end when the procedure does. We schedule reviews and follow-ups around your life, group staged treatment into planned steps when we can, and use each return visit to check healing and watch the details we flagged together. Between appointments we stay in touch with recall reminders and clear next steps, and if something feels off, we would rather see you quickly than have you wait and wonder.
The goal is a plan you understand, a team you recognize, and results that are checked over time rather than assumed.
Treating a teenager and treating an adult may use the same brackets and wires, but the planning conversations are quite different. Teen treatment rides on growth: jaws are still developing, teeth are still erupting, and timing can be chosen to work with a growth phase rather than against finished anatomy. The challenges are cooperation and change — retainers forgotten, elastics skipped, and a mouth that is still a moving target.
Adult treatment, by contrast, works on a finished skeleton. There is no growth to borrow, so every movement must be achieved mechanically, and the plan has to respect a lifetime already written into the teeth: fillings, crowns, worn edges, missing teeth and gum history.
Adults also bring different motivations, and we plan around them honestly. Some want the correction they missed or lost as teenagers; some are preparing for restorative work; some simply want crowded lower teeth — the classic adult complaint — to stop getting worse. Treatment is sequenced around work calendars, photographs, weddings and the realities of professional life, with the trade-offs of each appliance choice laid out in your written plan.
At Tribeca Dental Studio, 54 Warren St, New York, NY 10007, the consultation answers which movements your anatomy allows, how long they honestly take, and what the result will need from you to last — in writing, before you commit.
Here is the sentence every orthodontic patient deserves to hear before treatment starts, not after: teeth remember. The fibres and bone around newly moved teeth take time to reorganise, and the pressures of lips, cheeks and tongue that contributed to the original crowding do not retire when the braces come off. Teeth that were crowded tend to crowd again; teeth that were spaced tend to drift.
Retention is therefore not a cautious extra — it is the phase that keeps the result you paid for, in effort as much as money. Anyone who promises you a finish line after which nothing is required is leaving out the most important part of the treatment.
Some of the most valuable orthodontics we plan moves no tooth for cosmetic reasons at all. It is the preparatory movement that makes later dentistry possible — or makes it conservative. A tilted molar leaning into an old extraction space can be uprighted so an implant or bridge sits in proper alignment instead of at a compromised angle. Crowded or rotated teeth can be positioned so veneers or crowns need far less tooth removed to look straight.
A collapsed bite can be opened in a controlled way, creating the vertical space a restoration needs rather than grinding healthy teeth down to manufacture it. In each case, the orthodontics is invisible in the final photograph — and it is the reason the visible work succeeds.
