Our Services
Comprehensive Dental Care at Mercer Street Dentistry
Our full range of services covers routine cleanings, cosmetic enhancements, restorative work, Invisalign, and emergency care — all under one roof. Whatever your needs, our team is dedicated to providing the care you deserve in a welcoming and professional environment.
General Dentistry
Regular check ups and cleanings
Your overall health and well being is strongly influenced by the health of your gums. We strive to work with you, to customize a dental cleaning schedule that works to help you achieve optimal oral health.
Treatment of gum disease
In situations where the gums and bone around the teeth are more inflamed and infected, we offer treatment options to stabilize and restore the gums where possible.
Fillings
Fillings are necessary to treat cavities. There are different types of filling options that can be discussed at your visit.
Dental Implants & Restoration
Dental Implants
Dental Implants are an excellent solution for missing teeth. This option can be explored further at your visit, to see if you are a good candidate for an implant. Other options can also be discussed.
Extractions
Despite our commitment to save all teeth, sometimes the best treatment is to remove a tooth. We can provide a comfortable and supportive environment for this procedure. Speak to us about sedation if you think this would be needed.
Crowns
At times, a tooth needs more than a filling. In situations where the tooth has broken down significantly or it has been root canal treated, a crown is considered as a better treatment option. Crowns are made of very durable materials that can be tooth colored making them virtually indistinguishable from natural teeth.
Snoring Appliances
Snoring or mild obstructive sleep apnea can be treated with a custom designed oral appliance. The oral appliance moves your jaw forward, increasing the space in your airway. This may reduce the amount of vibration of the muscles and tissues in the back of the throat. In conjunction with a sleep study, we can find a solution to improve your sleep quality.
TMJ Pain
TMJ pain refers to discomfort or dysfunction in the temporomandibular joint (TMJ), which connects the jawbone to the skull. We are well-equipped to identify the underlying causes of TMJ dysfunction and offer tailored solutions.
Restoration
Treatment of broken teeth
Lost fillings
Treatment of tooth aches
Cosmetic Dentistry
Whitening of teeth
Veneers
Dental veneers are an excellent treatment to create a more uniform and esthetic smile. In situations where the teeth are discolored or spacing isn’t optimal, a thin layer of porcelain can be made for your teeth, to achieve a brighter, more pleasing appearance. We can evaluate and discuss whether this is a good option for you.

Invisalign
Invisalign is a modern, discreet alternative to traditional braces that uses a series of clear, removable aligners to gradually straighten your teeth. Each aligner is custom-made using advanced 3D imaging technology to ensure a precise and comfortable fit. Because the aligners are virtually invisible, you can improve your smile confidently—without the look of metal brackets or wires. Plus, they’re removable, allowing you to eat, drink, brush, and floss just as you normally would.
Treatment with Invisalign is simple and convenient. You’ll switch to a new set of aligners every one to two weeks as your teeth gently move into place. Regular check-ins with your dentist ensure that your progress stays on track. Invisalign can treat a wide range of orthodontic issues—from crowding and gaps to overbites and crossbites—all while fitting seamlessly into your daily life.
Ready to transform your smile the clear way? Schedule a consultation today to see if Invisalign is right for you.
Our Team
Dr. Sara Hansen and Dr. Rachel Park lead a friendly team committed to clear communication and gentle treatment. From routine hygiene to complex restoration, your comfort and confidence come first.
Emergency Care?
We understand that emergencies can happen unexpectedly, and our goal is to be available to address your urgent needs and alleviate your discomfort.
We are committed to creating a comfortable environment where every patient receives the compassionate, high-quality care they deserve.
First Visit?
During your first visit, we’ll perform a comprehensive oral examination. This includes evaluating each tooth, checking the gums for signs of gum disease, and thoroughly assessing the surrounding structures. If needed, digital radiographs will be taken to provide a complete picture of your oral health.
Because everyone’s needs are unique, this initial visit allows us to understand your specific dental requirements and create a personalized treatment plan just for you.

Do I need to bring anything to my first appointment?
What is your cancellation policy?
We understand that plans can change. If you need to reschedule or cancel your appointment, we kindly ask for at least two (2) business days’ notice. This allows us to offer your time slot to another patient who may be waiting for care.
