Services
General Dentistry
Our comprehensive general dentistry services focus on maintaining optimal oral health through regular checkups and preventive care. We provide thorough exams, digital X-rays, and professional cleanings to detect and prevent dental issues early. Our experienced team addresses common concerns like cavities, gum disease, and tooth pain while emphasizing long-term oral health maintenance.
Cosmetic Dentistry
Transform your smile with our cosmetic dentistry solutions including teeth whitening, porcelain veneers, and Invisalign clear aligners. Our dentists combine artistry with advanced techniques to address discoloration, misalignment, and imperfections. We create personalized treatment plans to help patients achieve natural-looking results that boost confidence and improve overall appearance.
Sleep Apnea Treatment
We offer effective treatment options for obstructive sleep apnea using custom oral appliances. Our dentists conduct thorough evaluations to determine the most appropriate solution for each patient. These comfortable, removable devices help maintain open airways during sleep, reducing symptoms like snoring and daytime fatigue while improving overall sleep quality.
TMJ Therapy
Our TMJ disorder treatment addresses jaw pain, headaches, and clicking sounds through customized solutions. We use bite analysis and diagnostic imaging to develop effective treatment plans that may include bite guards, physical therapy, or dental adjustments. Our approach focuses on relieving discomfort and restoring proper jaw function through conservative methods.
Bruxism Management
We provide specialized care for nighttime teeth grinding through custom-fitted mouthguards and Botox injections. Our dentists assess wear patterns and jaw muscle activity to determine the most effective intervention. Treatment helps prevent tooth damage, reduce facial pain, and protect dental restorations while addressing the underlying causes of bruxism.

Our family of four are clients of River Hills Dental for both general dentistry and orthodontics. I highly recommend River Hills for services in both areas. They are extremely friendly, as well as responsive and helpful with all of our needs - with two kids in braces, we have a lot of needs : We've already recommended friends to switch to River Hills and will continue to do so! I also am extremely satisfied with their location and their building is super clean and welcoming.

The staff of River Hills Dental are the real deal! They are fun, friendly, and knowledgeable. Their skills are top notch. Dr. Geislinger is a stud when it comes to his attention to detail, his friendly approach, and that face! I would recommend him for all of your needs, dentally speaking. On a serious note. He really cares about providing superior care and creates an easy going environment for his patients.

River Hills Dental is very clean and welcoming. I love their new update with the brick. The staff is friendly, prompt and very good at communicating if things will take a little longer or letting you know how long the appointment is expected to take. I very much appreciate this with kids and school/work schedules. I love that Dr. Dembiec comes out to communicate after the kids' appointments to give updates.

Super fun staff and they remember you on a personal level. I love one of the staff's personality, Jen, who makes the office so cheery, having fun with the customers and other staff, which contributes to the comfortable atmosphere. Another great asset to River Hills is that they are very respectful of the patient's wishes and individual needs and not in a rush to do a procedure that maybe can wait or allows other options to make patients feel comfortable and part of the decision.
