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
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.
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.
