First Visit Comprehensive Dental Examination

Comprehensive Exam


A full examination of your mouth and teeth will be conducted at your initial visit. The dentist must probe the gums to see if any pockets exist as this can lead to more severe periodontal conditions if not treated early. An inspection of all existing restorations (fillings and/or crowns) will be performed to look for leakage or cracks that may result in decay. The dentist also may evaluate possible cosmetic alternations that he/she may feel will improve your esthetic appearance and smile. Assessment of the occlusion for bite problems and an orthodontic screening are also parts of this thorough examination.

Periodic Exam

Periodic dental exams are routinely performed on established patients every 6 months after a comprehensive oral evaluation has been conducted at the patient's initial visit to the office. Dr. Nazarian will inspect existing restorations for possible cracks or leakage and determine any changes in the patient's oral health. Dental X-rays are usually taken at the time of visit as well to ensure that nothing is missed during the visual and clinical examination.


Digital X-Rays

Cosmopolitan dental uses the latest technology where X-ray sensors are used instead of traditional photographic film. Using Digital X-rays is more time efficient and images are developed instantly. There is also less radiation used to produce an image of similar contrast to conventional radiography.

X-rays taken at your visit are used to:

  • Show areas of decay that the dentist may not be able to see with just a visual examination
  • Find cracks or other damage in an existing filling
  • Evaluate the condition of bone supporting the teeth and to detect other problems not visible during the clinical examination

Preventive Cleaning

A dental cleaning is an important part of maintaining good oral hygiene and involves the removal of dental plaque and tartar from teeth with the intention of preventing cavities, gingivitis, and periodontal disease. It is recommended that patients get a professional cleaning every six months along with periodic exams.


A "deep cleaning" (also known as Scaling and Root-planning) is required when there is extra buildup of plaque and tartar along the gum line. The dentist will clean between the gums and the teeth down to the roots to remove the excess. You may not be aware that you have a problem until your gums and the supporting bone are seriously damaged. Using the latest technology and Digital X-rays, Dr. Nazarian will determine if a "deeper cleaning" is required during a checkup. The dentist may use a local anesthetic to numb your gums and the roots of your teeth. Planning and Root-scaling causes little or no discomfort.

Oral Cancer Screening

Oral cancer screening is a routine part of a dental examination. Regular check-ups, including an examination of the entire mouth, are essential in the early detection of cancerous and pre-cancerous conditions. You may have a very small, but dangerous, oral spot or sore and not be aware of it. To ensure that a spot or sore is not dangerous, Dr. Nazarian may choose to perform a simple test, such as a brush test. A brush test collects cells from a suspicious lesion in the mouth. The cells are sent to a laboratory for analysis. If precancerous cells are found, the lesion can be surgically removed if necessary during a separate procedure. It's important to know that all atypical and positive results from a brush test must be confirmed by incisional biopsy and histology.

Periodontal Care

Periodontal maintenance is initiated following periodontal therapy (scaling and root planning). Typically, periodontal maintenance includes an update of the medical and dental histories along with a soft tissue examination, removal of bacterial plague and calculus, and selective root planning and scaling. These procedures are performed at monthly intervals to assist the patient in maintaining good oral health.

Fluoride & Sealants

Fluoride helps prevent tooth decay by making the tooth more resistant to acid attacks from plaque bacteria and sugars in the mouth. It also reverses early decay. Fluoride is applied to the teeth as a varnish. This treatment contains a much higher level of fluoride than the amount found in toothpastes and mouth rinses and Dr. Nazarian will determine if this type of treatment is right for you.

Sealants decrease the risk of cavities and ensure a healthier smile. They are made of a plastic resin that is bonded to the tooth's surface sealing up pits or fissures where decay commonly occurs. The sealant process is simple; a conditioner is placed on the tooth's surface so the sealant can properly bond. Once the surface is prepared, the sealant is applied and a curing light is used to harden the plastic resin. Once the teeth are sealed, Dr. Nazarian will examine the sealants during routine checkup to ensure they continue to provide the protection needed.

Root Canal

Root canal treatment is used to repair and save a tooth that is badly decayed or becomes infected. Root canal procedures are performed if a pulp (soft tissue inside the tooth that contains blood vessels and nerves) in one of the teeth becomes injured or infected. There are many signs that a root canal may be needed. They include severe toothache pain upon chewing, prolonged sensitivity to heat and cold temperatures, discoloration of the tooth, and swelling and tenderness in the nearby gums. Sometimes there are no symptoms present.

Treatment involves one or more visits and there are several steps in the process of endodontic treatment that the dentist will perform to save your tooth. It is very important to follow your dentist's directions regarding the scheduling of your dental appointments so that your root canal treatment will be successful. Because a tooth that needs a root canal often is one that has a large filling or extensive decay or other weakness, a crown and post often needs to be placed on the tooth to protect it. This will prevent the tooth from breaking and will restore it to its full function. The need for any additional dental work will be discussed with you by the dentist.


A filling or restoration is a material that the dentist uses to fill a cavity after the removal of tooth decay. A filling is needed when tooth decay has caused a cavity (hole) on a tooth surface. If you don't get a filling, the cavity will get worse and lead to more severe problems such as bone loss and a root canal. Worn fillings or "silver" (amalgam) fillings should also be replaced before decay begins and causes infection.

Composite resin is used to fill the tooth. It is a tooth-colored filling and is used to create a more natural-looking smile.


There are several options for improving your smile, but opting for dental veneers has many advantages. Veneers are ultra-thin custom made laminates that are bonded directly to teeth. They are used as a cosmetic tool to close gaps, correct teeth that are chipped or worn, lighten teeth that are naturally yellow or have a gray cast that can't be whitened by bleaching, or to generally improve one's overall smile.

Veneers do not require any special care. Continue to follow good oral hygiene practices including brushing and flossing as you normally would.

Crowns & Bridges

A crown is a dental restoration that covers or "caps" the tooth to restore it to its normal shape, size and function. It encases the tooth and becomes the tooth's new outer surface.

A crown is used to treat teeth that have broken or decayed so much that fillings cannot fix them and for the improvement of the tooth's appearance. A crown is also used after root canal treatment to seal the tooth and prevent it from breaking.

A dental bridge is composed of two crowns for the teeth on either side of the gap. These two anchoring teeth are called abutment teeth with the false tooth being in between. Dental bridges are supported by natural teeth or implants. Thus dental bridges literally bridge the gap created by one or more missing teeth.

There are many benefits of a dental bridge. They include:

  • Restoring your smile and the ability to properly chew and speak
  • Maintaining the shape of your face
  • Distributing the forces in your bite properly by replacing missing teeth
  • Preventing the remaining teeth from drifting out of position

There are a few types of dental bridges and the dentist will determine which is best for you based on your dental and personal needs. The options will be discussed with you at your visit.

Dental bridges can last 5 to 15 years and even longer. With good oral hygiene and regular checkups, it is not unusual for the life span of a fixed bridge to be over 10 years.

Dental Implants

Cosmopolitan Dental is a full service dental practice, located in Midtown Manhattan, specializing in dental implant restoration. Whether your missing tooth is the result of periodontitis, tooth decay or an injury, we can help restore your smile with a beautiful new dental implant restoration that looks and functions just like a real tooth.

Significantly stronger than bridges or dentures, a dental implant offers a single and permanent solution to a lost tooth. The implant is integrated into your jaw with a small titanium screw and over the course of several months naturally bonds with your mouth. This procedure is relatively simple and is effective in almost all cases, so there's no need to put off restoring that great smile. Of course, we at Cosmopolitan Dental will make sure that you're kept comfortable and informed throughout the implant process.

A dental implant is a titanium metal replacement for a "tooth root". It acts as the root structure would for a natural tooth and are meant to replicate the natural function and appearance of a lost tooth. A dental implant is surgically implanted into the jaw and once allowed to osseo-integrate for two to six months, they are used to permanently anchor crowns, dentures or bridges.


There are many advantages to dental implants, including:

  • Improved Appearance: Dental implants look and feel like your own teeth. And because they are designed to fuse with bone, they become permanent.
  • Improved Speech: With poor-fitting dentures, the teeth can slip within the mouth causing you to mumble or slur your words. Dental implants allow you to speak without the worry that your teeth might slip.
  • Improved Comfort: Because they become part of you, implants eliminate the discomfort of removable dentures.
  • Easier Eating: Sliding dentures can make chewing difficult. Dental implants function like your own teeth, allowing you to eat your favorite foods with confidence and without pain.
  • Improved Self-Esteem: Dental implants can give you back your smile and help you feel better about yourself.
  • Improved Oral Health: Dental implants don't require reducing other teeth, as a tooth-supported bridge does. Because nearby teeth are not altered to support the implant, more of your own teeth are left intact, improving your long-term oral health. Individual implants also allow easier access between teeth, improving oral hygiene.
  • Durability: Implants are very durable and will last many years. With good oral care, many implants last a lifetime.
  • Convenience: Removable dentures are just that; removable. Dental implants eliminate the embarrassing inconvenience of removing your dentures, as well as the need for messy adhesives to keep your dentures in place.

If you are missing a single tooth or multiple teeth, dental implants are the way to go. They are the most natural looking way to replace missing teeth. Dental implants help maintain the integrity of the jawbone and prevent deterioration of the bone that can take place with missing teeth. It's important to replace missing teeth as soon as possible for the full function of chewing and for a healthy, happy smile.

Night Guards

Night guards are the most common treatment for Bruxism. Bruxism is an involuntary grinding of the teeth and clenching of the jaw muscles that occurs to some extent of most people. Bruxism often occurs during sleep and is one of the most common sleep disorders. Bruxism can range from mild wearing of the teeth and muscle tenderness to significant pain from dental and muscular issues. Dental issues that can arise from Bruxism include abnormal wear patterns on the chewing surface as well as abfractions on the gum line and fractures in the teeth. Over time severe wear can lead to tooth loss and significant gum recession. Since bruxism also includes clenching of the jaw muscles it can lead to facial muscle pain and headaches. Severe cases can lead to or be a result of Temporomandibular Joint Disorder or TMD.


Invisalign takes a modern approach to straightening teeth, using a custom made series of clear, removable teeth aligners that both dentists and orthodontists use as an alternative to traditional metal dental braces. There are many advantages to Invisalign, the most obvious being cosmetic. The aligners are transparent and are nearly undetectable when on. This method is preferred by those who want to get straighter teeth without the look of traditional metal braces. In addition, the aligners are also more comfortable than braces and because patients remove the aligners when eating, there are no restrictions on foods that can possibly damage the appliance.


Treatment for Invisalign begins with the dentist by taking dental impressions, x-rays and photographs of the patient's teeth and sending them to Align Technology where the aligners are made. The entire treatment process takes about one year depending on the complexity of the case. After treatment is complete, retainers composed of a similar material are usually required to be worn.

ZOOM! Teeth Whitening

The ZOOM! Chairside Whitening System is a scientifically advanced tooth whitening procedure. It is safe, effective and fast. In only one office visit, your teeth will become dramatically whiter. ZOOM! Chairside Whitening is ideal for anyone looking for immediate results. The convenience of ZOOM! Makes it the perfect choice for the busy individual. The procedure is simple and begins with a short preparation to cover your lips and gums, leaving only your teeth exposed. The ZOOM! proprietary whitening gel is then applied and works with the ZOOM! Whitening lamp to gently penetrate your teeth, breaking up stains and discoloration. With proper care and maintenance, your smile will have a lasting sparkle.

What Causes Tooth Discoloration?

There are many causes of tooth discoloration. The most common include aging and consumption of staining substances such as coffee, tea, colas, tobacco, red wine, etc. during tooth formation, consumption of tetracycline, certain antibiotics or excessive fluoride may also cause tooth discoloration.

Who May Benefit From Tooth Whitening?

Almost anyone may benefit from tooth whitening. However, treatment may not be as effective for some as it is for others. Yellow staining from aging, tobacco, dark cola, tea, coffee and red wine will achieve the greatest success with this procedure. Those patients with grey shading from tetracycline or other chemicals may experience less dramatic results, but should expect improvement from this brief procedure.


Is Whitening Safe?

Yes. Years of extensive research and clinical studies indicate that whitening teeth under the supervision of a dental professional is safe. In fact, many dentists consider whitening the safest cosmetic dental procedure available.

How Long Do Results Last?

By following some simple post whitening care instructions, your teeth will always be lighter than they were before. To keep your teeth looking their best, it is recommended that you floss and brush twice daily. For additional maintenance of your brighter, whiter smile we offer custom-made take home bleaching trays which will allow you to maintain the color of your smile. It is highly recommended to schedule an appointment for a ZOOM! Whitening consultation with Dr. Nazarian, expert in Teeth Whitening in New York City, during which all of your questions and concerns will be addressed.

Pediatric Dentistry

Dr. Nazarian works towards the maintenance of primary teeth (baby teeth) until they are naturally lost and towards prevention of tooth decay. This is due to the importance they serve in permitting children to chew properly and therefore maintain good nutrition, their role in speech development, and the maintenance of space for the eventual eruption of the permanent teeth. It is recommended that parents have their children see the Dentist as early as 3 years old to gain advice on how to make teeth strong and to learn about the importance of developing healthy eating habits and other ways to prevent disease from occurring.

Laser Therapy

Soft tissue laser therapy for deep cleanings presents many advantages. The laser beam seals as it cuts away damaged tissue, so bleeding is minimal. Because of the reduced trauma, most patients feel better than they would after traditional dental work. The diode laser represents the latest advance in laser technology. It is a surgical instrument that is reliable, portable, and powerful. It provides quick, precise dental surgeries. It also results in greatly reduced post-operative pain. Laser therapy has a broad range of applications, which includes cosmetic gum tissue reduction, and more exact preparations when providing our patients with their ideal smile.

Wisdom Teeth

A wisdom tooth refers to any of the usual four third molars. Wisdom teeth usually appear between the ages of 16 and 25. Most adults have four wisdom teeth, but it is possible to have fewer, or more. Wisdom teeth commonly affect other teeth as they develop, becoming impacted or erupt in a sideways or "non-linear" fashion. Often when this occurs, it is necessary to extract them. Sometimes these teeth can be a valuable asset to the mouth when healthy and properly aligned, but more often, they are misaligned and require removal.

Pinhole Technique
Chao Pinhole

Chao Pinhole® Surgical Technique

A breakthrough treatment for gum recession

What is gum recession?

Gum recession refers to the loss of gum tissue along the gumline. This can occur as a result of periodontal disease (gingivitis, periodontitis, advanced periodontitis), the natural aging process, or abrasive habits when it comes to brushing the teeth.

Why should gum recession be taken seriously?

When gum recession occurs, the root structure of the tooth becomes exposed. This means that tooth decay and other problems can affect the teeth along the gumline and beneath it. Since healthy gums are essential for a healthy mouth, getting gum recession treated is important for lasting dental wellness.

What is the Chao Pinhole® Surgical Technique (PST)?

The Chao Pinhole® Surgical Technique is a minimally invasive option for treating gum recession. Unlike traditional grafting techniques, PST is incision and suture free.

All of the tools and techniques used to perform the Chao Pinhole® Surgical Technique were created by Dr. John Chao, and who trained our doctor.

How does the Chao Pinhole® Surgical Technique (PST) differ from traditional gum grafting?

Traditional gum recession treatments involve the use of donor tissue or soft tissue grafts in order to rebuild the gumline. This soft tissue would be sutured in place and would join with existing gum tissue as it healed.

While this traditional grafting treatment is effective, comparable results with better patient experience can be achieved through the Chao Pinhole® Surgical Technique.

How is Chao Pinhole® Surgical Technique (PST) performed?

During the Chao Pinhole® Surgical Technique, a needle is used to make a small hole in the patient’s existing gum tissue. Through this pinhole, special instruments are used to gently loosen the gum tissue.

These tools help expand and slide the gumline to cover the exposed root structure.

There are no grafts, no sutures, and no incisions needed with the Chao Pinhole® Surgical Technique. It simply involves the adjustment of the existing tissue.

What are the benefits of Chao Pinhole® Surgical Technique (PST)?

The benefits of the Chao Pinhole® Surgical Technique are many:

  • Less discomfort for the patient after treatment
  • Faster recovery for the patient than traditional grafting
  • No need for uncomfortable sutures
  • No need for scalpels or invasive surgical tools
  • No need to take donor tissue from the patient’s palate
  • Excellent, natural-looking, long-lasting results
