Recently Dr. Jason Kasarsky was asked to contribute to a book about the secrets regarding professional and personal success of leading dentists. The chapter he wrote is a window into his philosophy. “The art of illusion has to be mastered,” writes Dr. Kasarsky, who asserts that his cosmetic dental skills can give patients the confidence to “go out and land that job, get that promotion and reach for the stars.”  

About My Practice

What's the most important thing you've learned from patients?

Patients respect you when you are honest and truthful. Deliver all of the news, even the tough-to-hear messages.

What qualities make a dentist successful?

In order to be successful, a dentist needs to have superior listening skills, compassion in the trenches, and the ability to maintain levity. I believe all successful individuals have the desire to succeed and push the envelope. You need to be open to paradigms and do your homework.

What new technology are you excited to use at your practice?

I am one of the first practitioners in New York City to be certified in the revolutionary technology of prepless DURAthinTM and MICROthinTM veneers. Get the smile you want without removing healthy enamel.

About Me

Why did you become a cosmetic dentist?

My grandfather was a physician and although I revered him, I didn't necessarily want to follow in his footsteps. I loved working with my hands. I was intrigued by the disciplines of dentistry.

In what ways are you a leader?

I am a visiting faculty member of the prestigious Spear Education Program in Scottsdale, Arizona, which offers a range of workshops, seminars and live patient courses to help dentists continue their education and fuel their passion for knowledge.

  1. How are porcelain veneers used to enhance a smile?
    What our experts say:

    They are used in many different ways.  If teeth can’t be bleached to achieve the color you want, you can cover the tooth structure with porcelain. Chips, cracks and fractures can also be covered with porcelain; and we can change the shape of a tooth with porcelain, or repair it with pieces that are missing.  Another thing we can do is change the length of the teeth or provide “quick orthodontics.” So, if you don’t want to spend a year moving your teeth around, we can use the “art of illusion” to create a beautiful esthetic smile in two to three visits. We can also add bulk to the teeth with porcelain. If the side teeth are placed narrowly when the patient smiles, and there is negative space between the corners of their lips and their teeth in the back, we can fill in that space by building out bulk, which broadens their smile. In other words, we have to look at the mouth as a stage. The lips become curtains and the teeth become players.  There are still players in the back of the stage and people still notice them; and in the mouth, they notice them even more if you change the front teeth but not the ones in the back.

  2. What are the benefits of tooth-colored fillings? What is the filling made out of?
    What our experts say:

    One benefit is there’s no mercury, which is a known carcinogen.  Another benefit is when tooth-colored fillings are placed with adhesives (when using adhesive dentistry), we are not using undercuts to help retain the filling; so the preparation into the good, solid tooth structure is minimal or conservative. The adhesives, or glue, help hold the filling material, and that filling material can contain fluoride, and can mimic the natural beauty of the tooth structure by blending various colors of composite. The composite is kind of like a “space-age plastic,” that is healthier and more conservative than the silver that was used in the past. On a microscopic level, the tooth structure looks like the Rocky Mountains. The composite flows into the “Rocky Mountains” and is then cured (or set) with a bonding light. It sets it into the “nooks and crannies” of the “Rocky Mountains” and that’s what holds it in place.  Another advantage to using tooth-colored fillings is that they can be highly polished and, if it’s done well, the structure of the tooth can be indistinguishable from the filling material.

  3. What type of whitening treatment is most effective?
    What our experts say:

    The bottom line is they all work.  You can’t say one is better than the other, some are more expensive, some take more treatments to work and some may work better for some than for others. It’s really a dollars and sense and length of time issue. There are strictly take-home whitening systems, where we make a set of trays for you, and you put a whitening gel into the trays with instructions to use at home. In-office whitening is usually a gel that goes on the tooth and is activated with a light, such as Zoom, that produces light and a little bit of heat.  Another in-office treatment is laser whitening. It uses laser energy to activate the whitening gel. I use a laser because it produces far less heat than any other light source, and it works quicker.  In-office treatments will get teeth whiter faster than take-home treatments.

  4. What are dental implants and when are they used?
    What our experts say:

    We use implants when somebody is missing a tooth, or if they have a broken tooth extracted and it can’t be saved. A single implant fixes a one-tooth problem with a one-tooth solution. If you have a space, we can put an implant into that space and put a crown on top of it; as opposed to having a space, and having to grind down the tooth in front and behind the space and then making a bridge to bridge the gap. That way uses three teeth to solve a one-tooth problem. Other times, implants are used if someone is missing many teeth. An implant equals the root that used to be there. On top of the implants, we can put teeth (fabricated crowns) that stay in the mouth.  So instead of removable piece like dentures, the teeth stay there. They can be cemented into place, or we can use tiny titanium screws into healthy jaw bone that hold them into place. The patient still has to clean them and go to the hygienist for cleanings.  They can still get periodontal disease, but they don’t decay.

  5. How do you fix a “gummy smile”?
    What our experts say:

    There are different ways. If there is excess gum in a healthy tooth (not a periodontally involved tooth), we can use a laser and remove the excess tissue.  (Some dentists use a scalpel, but I use a laser.)  Or, we can move the teeth, if the teeth are too far down in the front and the lip is high, (retrusion). If we push the teeth up, the gum goes with it.  If the tooth is periodontally involved, we sometimes need to cut the gum structure, and sometimes the bone has to be cut as well to improve a gummy smile. We can also lower the lip, if it is too high, by a surgical procedure to bring the lip down, so it will cover the gums. With all the options, we have to look at the individual; there is no one procedure that fits all patients.


Alleviating Dental Fear

Tate, Age 42
""I suffered from a broken tooth and my crowns were 10 years old, but I had a true fear of the dentist. Dr. Kasarsky and his warm staff spent time speaking with me about my options and we ultimately decided upon sedation dentistry, in which Dr. K is a specialist. The sedation was really helpful, enabling Dr. K to insert my new porcelain veneers and crowns. Dr. K is understanding, committed and skilled with an aesthetic eye—I highly recommend him.""
