Our Office

At Salem Creek Family Dental, we want to create a warm and inviting atmosphere for our patients that feels much less like a dental office and a lot more like home. We work with kids and adults alike and encourage families to schedule family block appointments with our team so the entire household can have their routine care taken care of in one day. We also accept emergency appointments, so should you or a loved one need to see an experienced dentist in Murfreesboro right away, please give our office a call.

If there’s anything we can do to make your visits better, please let us know, and we will do our best to accommodate you!

Modern Dental Technology

Our office invests in the latest dental technology to keep our care as comfortable, effective, and efficient as we can. We use a digital scanner instead of taking traditional dental impressions, which means patients can receive highly accurate impressions without having to bite down into a tray of goopy dental putty. Our digital X-rays capture detailed images within seconds and emit far less radiation than older X-ray machines. We even utilize intraoral cameras so that both the doctor and patient can get an up-close view of the patient’s teeth and gums.

Kid-Approved Care

Salem Creek Family Dental accepts patients of all ages, but we have a special place in our hearts for working with children and teaching them the importance of dentistry and taking care of their oral health. While every patient is unique, we recommend that every child begin attending regular visits around the time they turn one or when their first tooth grows in, whichever happens first. Our lobby contains a kids’ play area full of books and toys, and after every successful dental visit, our young patients are welcome to pick out a toy from our prize box. We want our pediatric patients to have positive dental experiences so they enjoy their dental appointments now and for many years to come!

Dr. Ashley Costello

Dr. Costello

After growing up in Murfreesboro, Dr. Costello attended the University of Tennessee in Knoxville and then went on to earn her dental degree from the University of Tennessee Health Science Center in Memphis.

After spending two years practicing dentistry in Houston, Texas, she and her husband, Nick, decided it would be best to relocate back to Tennessee to be closer to family. Dr. Costello could not be more excited to be practicing dentistry in her hometown of Murfreesboro, Tennessee.

Dr. Costello truly enjoys fostering relationships with her patients. She shows this same passion for people both locally and abroad and hopes to spread the love of Christ through her gift of dentistry. She participates in dental mission trips and also volunteers with the Dentistry from the Heart and Hope Smiles organizations.

In her spare time, Dr. Costello enjoys running, shopping, and trying new restaurants. She and her husband have three kids, Conner, Camden, and Chloe, who all enjoy visiting the office frequently. The family also loves spending time with their dog and cat, Bonzo and Cooper.

Dr. Sifuentes

Dr. Amber Sifuentes was raised in Ripon, California, a small town located in the northern region of the state. She earned her Bachelor of Science in Biology at California State University Stanislaus, where she was involved in many extracurriculars and enjoyed giving back to her community. Dr. Sifuentes moved to Utah where she received her Doctor of Dental Medicine degree at Roseman University of Health Sciences, located in South Jordan.

After spending four years in the beautiful state of Utah enjoying the outdoors, and with frequent visits to Tennessee, Dr. Sifuentes decided to move to Nashville, TN to pursue her career in dentistry alongside Dr. Costello.

Dr. Sifuentes has always had a passion for helping others and has a huge heart for providing care for her community. She is looking forward to building relationships with patients and putting patient comfort as her top priority. She is excited about becoming a member of and serving the Murfreesboro community!

Outside of dentistry, you can find Dr. Sifuentes exploring her new city in Nashville, spending time with family and friends, and enjoying the outdoors! She also loves spending time with her dog Roman, who has been by her side for 9 years!

Costello kids

Ambassadors of Goodwill

Conner, Camden & Chloe Costello

When you enter our office, you may be greeted by one, two, or possibly three of our Ambassadors of Goodwill. They often spend their time in the office playing in the lobby, hiding under counters, or reviewing treatment plans with patients (okay not the last one, but just give it a few years!) When Conner, Camden, and Chloe are not working in the office, they enjoy spending time with family, playing with toys, and sharing food with their dog. Even if you don’t need to see the doctor, drop in and say hi. They will be glad to see you!

My name is Salina. I am originally from Turlock, California but moved to Middle Tennessee in the summer of 2022.

In the office you will usually find me at the checkout desk scheduling your next appointment and/or in the operatory with you reviewing treatment plans. What I love the most about Dentistry is when a patient leaves with a smile of their face and the confidence of understanding their dental needs.

Outside of work, you can find me traveling and exploring this beautiful state. I really enjoy spending time with my sisters, nephews and friends and you can always catch me with a coffee in hand, laughing and smiling.
