Dentist in Littleton, CO
Dentist in Littleton, CO At Littleton Dental Collective, we continue a tradition of trusted dental care in Littleton, CO, that spans more than 50 years. Dr. Ronald Grout established the practice in 1971, and his son, Dr. Jeffrey Grout, subsequently guided it under the name Grout Family Dentistry. In June 2026, Dr. Euijoon EJ Park, DMD, became the owner and ushered the practice into its next chapter as Littleton Dental Collective. We remain committed to the warm, patient-first values that have shaped our practice across generations.

Dr. Park received his DMD from Case Western Reserve University School of Dental Medicine and has pursued more than 670 hours of continuing education in dental implants. As a surgical mentor for the Global Dental Implant Academy, he also trains other dentists through live-patient surgery courses. Associate dentist Dr. Megan Kack, DDS, is a University of Minnesota School of Dentistry graduate who focuses on general and cosmetic dentistry. Together, our team provides comprehensive care for patients of every age, including preventive, restorative, periodontal, implant, cosmetic, and emergency services. We offer exams, cleanings, oral cancer screenings, sealants, night guards, mouthguards, fillings, crowns, bridges, root canals, dentures, implant surgery and restoration, implant-supported dentures, full mouth reconstruction, whitening, veneers, bonding, smile makeovers, extractions, and wisdom teeth removal.

Products & Services

Emergency Dentistry
read moreOur emergency dentistry service is designed for dental problems that require immediate attention rather than a routine appointment. We respond quickly, assess the affected area, provide relief, and develop a targeted treatment approach based on your needs. Whether you are experiencing intense discomfort, a knocked-out tooth, a broken tooth, or swelling, timely care can help prevent further harm.
Teeth Extraction
read moreWe provide gentle teeth extraction when a tooth can no longer be saved or is causing problems for your oral health. Our approach includes thorough numbing and careful removal to keep the procedure as comfortable as possible. Afterward, we provide clear recovery guidance and discuss replacement options when appropriate to help maintain a healthy, complete smile.
Dental Implants
read moreOur dental implant treatment replaces missing teeth from root to crown while supporting a natural-looking, stable smile. We carefully evaluate your teeth, gums, and jaw before creating a personalized treatment plan and placing the titanium implant post. After healing and fusion with the bone, we complete the restoration with a custom-matched crown for comfortable, natural function.
Teeth Whitening
read moreWe provide professional teeth whitening to brighten smiles affected by stains and discoloration from coffee, tea, wine, tobacco, food, and natural aging. Our treatment uses professional-strength whitening agents to deliver faster, visible results than many over-the-counter products. Whether completed in our office or with a custom take-home kit, whitening is performed with careful attention to your teeth and gums.
Veneers
read moreOur dental veneers are crafted to create a more even, refined smile while concealing imperfections such as discoloration, small chips, gaps, and minor misalignment. We customize every veneer according to the shape and shade selected for your smile, helping the result look natural. Porcelain and composite options provide a lasting approach to enhancing your smile's appearance.
Dental Crowns
read moreWe provide custom dental crowns to restore teeth that are cracked, broken, worn, weakened by decay or large fillings, or treated with a root canal. Each crown is crafted from durable, tooth-colored material and matched to your surrounding teeth for a natural appearance. Our process includes careful preparation, precise fitting, secure placement, and final adjustments for comfortable function.
Root Canal
read moreOur root canal treatment removes infected or inflamed tissue from inside the tooth, then cleans, disinfects, and seals the area. We carefully numb the treatment area to keep you comfortable throughout the procedure. This approach relieves pain, stops infection, and preserves your natural tooth. A final restoration can help restore normal strength and function.
Teeth Cleaning
read moreOur professional teeth cleaning service addresses hardened buildup from areas that daily brushing and flossing may miss. We carefully remove plaque and tartar, polish the teeth to reduce stubborn stains, and provide fluoride for added protection against decay. During the visit, we also offer personalized oral hygiene guidance to help maintain your results.

I wanted to take a moment to express my sincere gratitude and appreciation for the outstanding dental care and service I have received during my recent visits to your clinic. From the moment I walked through your doors, I was impressed with the professionalism, expertise, and friendliness of your staff and associates.

The level of care and attention to detail provided by your team is truly commendable, and I wanted to highlight a few key aspects of my experience:

Reception/Assistance: Your receptionists and administrative staff were always welcoming, courteous, and efficient. They made scheduling appointments, handling insurance matters, and settling payments a breeze.

X-ray and Diagnostic Services: The thoroughness and precision of your x-ray and diagnostic procedures instilled a sense of confidence in the treatment plans. The technicians were not only skilled but also made me feel comfortable throughout the process.

Cleaning Services: The dental hygienists who performed my cleanings were gentle yet thorough. They took the time to explain proper oral hygiene practices and provided valuable tips for maintaining my oral health.

Crowning and Root Canal Procedures: Dr. Jeff Grout and the rest of the dental team displayed exceptional expertise during my crowning and root canal procedures. Their attention to detail and commitment to patient comfort were evident throughout the treatments.

Referrals and Coordination: Whenever I required specialized services beyond your clinic's offerings, your team's ability to provide referrals and coordinate with other specialists was seamless. It eased any concerns I had about the complexity of my dental needs.

Overall, the high quality of care I received at Grout Family Dentistry has left a lasting impression on me. It's clear that your team values patient well-being and strives for excellence in all aspects of dentistry. I can confidently...

My family and I have been going to Dr. Jeff Grout for so many years, Ive lost count. I entrust my teeth with Jeff and his staff and they always do a great job from cleanings and exams, to fillings and crowns. He is a conservative dentist who keeps a close eye on changes to your teeth, recommending when the time is right if a tooth needs more than just watching. He and his team are knowledgeable, gentle and thorough.

This was the BEST dentist appointment ever! The staff was friendly and welcoming. It had a "family " feeling that we both appreciated. Our dentists explained everything in detail, explained the X-rays and gave us a printed plan of action. They are the best. Jim and Sue Wallendorf

Both my son (8) and I needed small fillings after our most recent cleanings. My son is very sensitive about everything and needs things explained thoroughly with time to answer detailed questions. Dr. Jeff and his staff were phenomenal with him. They took their time and spoke to him very clearly. His anxiety was far less than I anticipated because everyone took their time to explain things to him. As a mom, I appreciate that more than anything. I asked what he would rate his experience and he said he would give him 10 stars if he could. My filling was about as fun as it could be for a dental procedure- painless, quick, and I was kept in the loop about everything that was happening next. I fully trust Dr. Jeff and his team for our dental care!

Grout Family Dentistry was the first dentist appointment for our kids that 1) didnt end in tears and 2) that the kids *actually* said they wanted to go back towe were won over on our first visit! Everyone at Grout is so incredibly kind, from the minute you walk in to the moment you leave. They take their time to communicate well, answer questions, and connectdoesnt feel like so many other medical professionals who just wants to get you in and out. We are so thankful to have finally found a great dentist!
