Dr. Rebecca Long is a compassionate and highly educated dentist who always has the best interests of her patients in mind. She loves the relationship-building aspect of dentistry, believing that genuine connections are the start of great oral health care. If you’re looking for a dentist near West Austin, Dr. Long infuses trust, empathy, and transparency into every appointment.
Growing up, Dr. Long bounced between dream careers, from a waitress on wheels to an astronaut and a doctor. All that time, her parents supported these dreams and gave her the courage to pursue her ultimate passion.
As a child, Dr. Long underwent years of dental work, from orthodontics to gum surgeries, so she was no stranger to the transformations dental care could offer. But it wasn’t until after her hometown dentist restored her broken front tooth to like-new condition during a break in college that her mind was made up.
Dr. Long earned her undergraduate degree from the University of Virginia and went on to complete her Doctor of Dental Surgery at the University of Illinois at Chicago College of Dentistry. Since then, she’s exemplified her belief in staying current on all the latest technology and techniques in the field by taking over 600 hours of continuing education.
She’s also studied under top instructors at the Spear Education Center in Scottsdale, AZ, is currently enrolled in the Dawson Academy’s advanced cosmetic dentistry program, and regularly attends high-level conferences such as the Chicago Midwinter Meeting and the American Academy of Cosmetic Dentistry conference. She is proud to have earned her Fellowship in the Academy of General Dentistry—an honor held by only 6% of dentists nationwide.
Outside the office, Dr. Long enjoys a joyful life with her husband Ryan (also the practice’s business manager), their two cats Kismet and Kylo Roo, and their rescue dog Lulu. She’s an animal lover, an avid reader, and a frequent traveler with a special love for the outdoors.
Whether she’s in the office or out exploring the world, Dr. Long brings her whole heart to everything she does. So, if you’re searching for a dentist near you, give Westlake Hills Dental Arts a call. Dr. Long would love to meet you, hear your story, and help you build a treatment plan that meets your needs and allows you to live a better life.

The first step is always to stay calm and assess your situation. If you have a fever related to infection, a broken jaw, difficulty breathing, or a swollen throat, go to the nearest emergency room immediately. However, for dental-specific emergencies, like a lost restoration, broken tooth, or knocked-out tooth, contact our dental office near West Austin right away.
During the call, we’ll schedule your emergency appointment and give you some important first-aid information to help you cope before you arrive. We keep room in our schedule every day during our normal hours for urgent visits so we can get to you quickly and help you find relief.
Your search for the right dentist should start with your personal needs and goals. Make a short list of the services you’re looking for—whether that's cosmetic dentistry, dental implants, preventive care, or nightguards for bruxism. Then, find practices that offer those specific treatments.
After that, consider other factors, like convenient hours, flexible payment options, modern technology, and strong patient reviews. A great dental home should make scheduling easy, support your long-term oral health, and make you feel comfortable at every appointment.
Once you know what you want, you can read patient reviews as well as doctor and staff bios on the website before finally scheduling an appointment.
A routine dental check-up and cleaning in Austin typically ranges from $100 to $200 on average. This visit usually includes a comprehensive oral exam, a professional cleaning, and any necessary X-rays.
Dental benefits can help you significantly reduce these costs by covering preventive care at little or no out-of-pocket expense. If you don’t have dental benefits, our office near West Austin accepts CareCredit, which is a convenient financing platform that allows you to break costs into manageable monthly payments.
Our team is always happy to help you find a financial path forward for your smile, whether it’s helping you check your dental benefits or filing claims on your behalf.
