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 the teeth into proper alignment for a more beautiful smile and healthier teeth. After a consultation with Dr. Koster, patients receive a series of custom-made aligners that are worn at all times but can be taken out to eat, brush and floss your teeth, 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 discoloration, 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.

Retainers in Locust Valley, NY

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 reduced 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 spots, 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.

Sedation Dentistry FAQs

Do I need sedation for tooth extraction?

Typically, your dentist will administer local anesthesia and sedation before a tooth extraction so you are pain-free during the procedure and remain relaxed.

How does sedation dentistry work?

There are different types of sedation dentistry available that work in different ways. Your dentist may prescribe an oral sedative, which you can take before your procedure. Nitrous oxide is also an option, which you will breathe in before your procedure. After the medication has taken effect, you will feel relaxed, drowsy, and content.

Is dental IV sedation safe?

Dental IV sedation is safe. For some patients, including those with sleep apnea or who are obese, IV sedation may not be recommended.

What are the side effects of oral sedation?

Some common side effects of oral sedation include dizziness, dry mouth, nausea, or headaches. Not all patients will experience these side effects.

What can I expect after sedation dentistry?

After a sedation dentistry procedure, you can expect to feel drowsy and should have someone drive you home. It's best to avoid drinking alcohol, a strenuous activity like exercise, and driving or operating machinery for at least 24 hours.

Will I feel any pain with dental sedation?

IV sedation allows you to feel no pain during your dental procedure.

Does sedation dentistry cost more?

There is a cost associated with sedation dentistry that patients would not have to pay for procedures that don't require sedation. Generally, sedation is charged according to the amount of time you are sedated.

Is dental sedation safe?

Dental sedation is safe, but it's important to choose an experienced, trustworthy dentist for your sedation procedure.

Why no food or drink before IV sedation?

IV sedation stops your body's reflexes temporarily. This causes a risk of vomiting if your stomach contains food or drink, so it's important to avoid eating or drinking for several hours ahead of your procedure

What should I do before dental sedation?

Before your dental sedation, you should avoid eating or drinking for about 6-8 hours, arrange for someone to drive you home after the procedure, and avoid taking medication unless your dentist has approved it.
