Both my daughter and I have been patients of Dr Koster's and we couldn't be happier. She has a gentle demeanor and is super thorough. She shows genuine concern for our teeth and gives us advice on what to keep doing/do more of to keep them healthy. Her office staff are really nice too. I am grateful to be in their good hands. "

Exams & Cleanings

Oral cancer screenings, gum disease evaluations, and fluoride treatments create healthy and happy smiles for patients of all ages. Our hygienists and dentists are gentle and thorough, helping patients feel in control of their dental health.


Fix cavities with white fillings. They aren’t just better looking, they’re better for your teeth, too! They’re smaller than silver mercury-amalgam fillings and actually strengthen your teeth.

Following a root canal or due to significant tooth loss, crowns restore the shape, function, and appearance of your tooth with a natural tooth-colored porcelain crown. They’re durable and look just like or better than your natural teeth!

Gum Disease Treatments

Gum disease is the #1 cause of preventable tooth loss in adults. Deep cleanings and other non-surgical gum disease treatments restore your gum health.
