A crown lengthening procedure is necessary when there is not enough tooth structure above the gum to support a filling or crown. Severe tooth decay or injury can result in teeth that are broken or destroyed below the gum line. A crown lengthening procedure will adjust the gum line and expose more of the natural tooth to provide more stability for any necessary restorations.

A crown lengthening procedure can also be used to help reduce a "gummy" smile. This occurs when the gum extends too far down the length of the teeth, causing the teeth to appear short. With a crown lengthening, some of the gum tissue surrounding the upper teeth can be removed to reveal more of the natural tooth, creating a natural look and improved smile with greater symmetry at the gum line.

Crown lengthening is performed under a local anesthetic and can be combined with sedation for patients who are anxious about dental treatments. During the crown lengthening procedure, excess gum and bone tissue is removed through an incision that flaps the gums away from the teeth. Once enough tooth structure is exposed, the dentist will wash the area with salt water and stitch the flaps back together.

In some advanced cases it may be necessary to remove some of the bone structure as well. The height and width of the bone surrounding the tooth is contoured, and the gums are then re-positioned.

You can return to normal daily activities in a few days and will need to return to the dentist approximately 7 to 10 days after the crown lengthening procedure to have the sutures removed. Complete healing typically takes one to two weeks. Dr. Rozenberg will discuss the post-surgical visits included in your treatment plan.


Invisalign is a clear, comfortable and convenient way to straighten teeth, offering many advantages over traditional metal braces. The Invisalign system uses a series of clear, removable teeth aligners that are virtually invisible. With Invisalign, no one will know you’re wearing braces unless you tell them. Not only is Invisalign more aesthetically pleasing than metal wires and brackets, the Invisalign system moves teeth more precisely than metal braces, and often requires fewer appointments and less overall treatment time. Additionally, Invisalign aligners can be removed for eating, brushing and flossing, allowing you to maintain cleaner, healthier teeth during your orthodontic treatment. With Invisalign, food won’t get caught in wires and brackets, and there are no restrictions on what foods you can eat. Invisalign aligners are made from a smooth, comfortable plastic, so they won’t irritate and scratch your mouth and gums the way metal braces can. Treatment with Invisalign usually lasts about a year for most patients.

Invisalign works by gently and gradually moving teeth, using a series of clear plastic aligners that snap onto your teeth and are virtually invisible. Invisalign offers targeted, precise movement of teeth. With traditional metal braces, teeth are wired together, so there can be some unintentional movement of adjoining teeth that may need to be corrected later in your treatment. Because Invisalign moves only the teeth you want to move, overall treatment time may be less than with traditional braces.

Patients wear each set of Invisalign aligners for about two weeks each for 20 to 22 hours a day. Invisalign aligners can be removed for eating, brushing and flossing, as well as for photographs and even occasional special events.

During your initial appointment, we will thoroughly examine your teeth and discuss your goals and expectations with you. We will take x-rays, pictures and impressions of your teeth so that we can map out a precise treatment plan. Your Invisalign aligners will be custom-made to fit your exact treatment plan. With Invisalign, there’s no need to tighten wires every four weeks. You simply swap out your aligners for the next in the series. Follow-up appointments are usually scheduled for every six to eight weeks so that we can monitor your progress.

FAQs About Invisalign:

Does Invisalign Work as well as Traditional Braces?

Absolutely. Invisalign moves teeth gradually and precisely into their new position, without moving adjoining teeth. In fact, overall treatment time with Invisalign is about a year, which is usually less than with traditional metal braces.

Is Invisalign Comfortable?

Yes. Invisalign aligners are made from a clear, smooth plastic that is custom-fit to your mouth. There are no metal wires and brackets to irritate or scratch your mouth.

Can I Remove the Aligners?

While Invisalign aligners should be worn every day for at least 20 to 22 hours a day, they can be removed for eating, flossing and brushing. This allows you to keep your teeth cleaner and healthier during your treatment. Additionally, Invisalign aligners can be removed when taking photographs, and even if you have a special occasion you'd like to attend, like a wedding or a prom.


As we age, our skin becomes less elastic and loses volume, particularly around our face. Smile lines become more prominent, as do wrinkles around the mouth. At Lana Rozenberg, D.D.S. in New York City, we want all of our patients to feel confident about their smiles without having to undergo invasive treatments.

Dr. Rozenberg offers patients a scalpel-free way to improve their smile and facial structure. Before we create your brand new smile, you’ll start with a consultation to discuss several factors, such as face shape, tooth size, age and skin tone. Each patient is different and has specific needs, which we take into consideration when discussing your new smile.

During the Rejuvenating Smile Lift procedure, the outer portion of the teeth is built up through the use of veneers. These veneers add more translucencies to the teeth and widen the smile, creating a fuller and more youthful smile. By simply setting your teeth in the correct position, we can help ensure that your teeth are able to support your lips in a fuller, more youthful looking smile.

With our Rejuvenating Smile Lift procedure, there’s absolutely no downtime, so patients can leave our offices with a rejuvenated smile and added confidence.

For individuals with teeth that are poorly aligned, irregularly shaped or chipped, enamel contouring is a great alternative to re-create a beautiful smile. Enamel contouring is a safe and subtle way to refine your smile for an instantly rejuvenated look. In select cases, the appearance of top and bottom teeth can be improved by recontouring the enamel.

Dr. Rozenberg will start by marking your teeth with a pencil. This will aid her in the sculpting process. During the procedure, a sanding drill or laser is used to remove small amounts of the surface enamel that is overlapping or poorly shaped. Abrasive strips are then used between your teeth to shape the sides of your teeth. Dr. Rozenberg will then polish the sanded teeth to complete your perfect smile. In cases where the poor alignment is more pronounced, resin may be bonded to teeth to create a better look.

This procedure is typically completed in one appointment and is simple and painless, so a local anesthetic is not administered. The change is immediate and permanent. Porcelain veneers and whitening are a few cosmetic dental procedures that couple well with enamel recontouring to enhance your perfect smile.


Your smile is one of the most important factors when making a first impression. How confident is your smile? Lana Rozenberg, D.D.S. offers patients the Zoom!® Chairside teeth whitening system to create beautiful, brighter smiles. Zoom!® makes it faster and easier than ever before to achieve a sparkling smile.

Prior to receiving the Zoom!® teeth whitening treatment, it is recommended that patients receive a teeth cleaning. On the day of your treatment, a technician will cover your lips and gums, leaving only teeth exposed. The Zoom!® whitening gel is applied, and a specially designed light is placed over the teeth. During the course of an hour, the gel and Zoom!® light gently penetrate teeth to break up stains and discoloration. Patients can comfortably watch television or listen to music during the teeth whitening procedure.

There are no side effects from Zoom!® teeth whitening although some patients feel slight discomfort from the minimal heat produced from the light. On rare occasions, patients may experience a minor tingling sensation immediately after the procedure. Dr. Rozenberg can give you anti-sensitivity toothpaste to use prior to treatment to reduce the chance of these side effects.

Zoom!® teeth whitening provides immediate results, whitening teeth up to 8 shades in a session. By practicing proper dental maintenance and following a few simple post-whitening care instructions, your teeth will always be lighter than they were before the treatment.
