Invisalign in Locust Valley, NY

Many dental patients in Locust Valley struggle with misaligned or gapped teeth but do not want the discomfort or hassle of metal braces. Invisalign aligners are a great option for these patients. Invisalign uses custom plastic aligners to gradually shift crooked or misaligned teeth into proper alignment for a more beautiful smile and healthier teeth.

After a consultation with Dr. Koster, Invisalign patients receive a series of custom-made aligners that are worn at all times but can be taken out to eat, brush, floss, or as needed for activities like sports or playing an instrument. The aligners are nearly invisible, and treatment is complete within an average of 12-18 months.


Veneers in Locust Valley, NY

Veneers are an increasingly popular option in cosmetic dentistry. This is because, unlike other treatments, veneers can solve multiple cosmetic issues at once, including discolored teeth (teeth whitening), chips, cracks, and minor gaps. Locust Valley Dentists offers several types of veneers to suit a variety of needs and budgets, including porcelain veneers, Lumineers, no-prep veneers, and composite veneers. During your consultation, Dr. Koster can make a recommendation based on your unique dental needs for long-lasting results.

What are dental veneers, and how can they improve my smile?

Dental veneers are a thin shell that are attached to the natural teeth to provide an enhanced cosmetic appearance. Veneers can address issues like discoloration, cracks, chips, minor gaps, and other aesthetic concerns.

How do cosmetic dental procedures differ from general dentistry?

Cosmetic dentistry focuses on the aesthetics and appearance of the teeth, while general dentistry is for prevention and treatment of oral health issues.

What are dental crowns, and when are they typically recommended?

Dental crowns are tooth-shaped caps placed over a tooth to restore its shape, size, strength, and appearance. They are typically recommended to protect a weak or damaged tooth, restore a broken or worn-down tooth, cover a tooth with a large filling, support a dental bridge, or improve the appearance of misshapen or discolored teeth. Additionally, crowns are used to cover dental implants and protect teeth after root canal treatment.

What is the process of implant restoration, and how long does it take?

The process of dental implant restoration involves surgically placing a titanium post into the jawboneand allowing it to fuse with the bone over several months. Next, an abutment is attached to the implant post, followed by the placement of a custom-made crown to restore the tooths function and appearance. The entire process can take anywhere from 3 to 9 months.

Are there any risks or side effects associated with cosmetic dentistry procedures?

Although uncommon, risks associated with cosmetic dentistry procedures include tooth sensitivity, infection, nerve damage, and complications related to anesthesia. Additionally, there can be issues with bite alignment, the durability of the dental work, and potential dissatisfaction with the aesthetic outcome.

Retainers in Locust Valley, NY

After orthodontic treatment, such as Invisalign, retainers are used to maintain the new position of the teeth and prevent shifts or crowding. Dr. Koster can create custom removable retainers or install permanent retainers, which are small wires that are affixed to the back of the teeth. These retainers ensure that your once crooked teeth stay in their new straight position.

Gum Contouring in Locust Valley, NY

Gum damage or excess tissue that creates a “gummy smile” can be addressed through another common cosmetic dental procedure known as gum line contouring. Dr. Koster offers this service so that patients in Locust Valley can feel more confident in showing their smiles.

Advances in dental laser technology means that gum contouring can now be completed quickly, precisely, and with reduced discomfort, forgoing the scalpels and sutures of the past. Patients seeking this kind of dental work will also benefit from reduced recovery time following laser gum contouring. Results from gum contouring last a lifetime, making it one of the most satisfying and maintenance-free treatment options for a more satisfying tooth structure and smile.

White Spot Treatment in Locust Valley, NY

White spots on the teeth are typically the result of a process known as decalcification. This occurs when the phosphorous, calcium, or other minerals are stripped away from the teeth, causing a reduction in tooth enamel.

Excess fluoride, poor diet, enamel hypoplasia, staining from metal braces, side effects from medication, or bacteria and plaque as a result of poor dental hygiene can all result in white spots on the teeth. Dr. Koster can remove white spots and restore an even, unblemished smile using ICON treatment. This involves resin infiltration to fill in the white spots.

After adhering resin to the white spot on the tooth surface, the teeth are polished for a clean, shining, healthy appearance. White spot treatment with ICON can be completed in as little as an hour and is completely pain-free. Following treatment, there is no downtime or recovery period necessary. Dr. Koster will advise how to care for your teeth to maintain your results and oral health long-term.
