Gentle care for every member of your family.
At Sunny Hills Dentistry, we believe great dental care should feel like coming home. Led by Dr. Sojung Jang, DDS — with over 20 years of experience — our Fullerton family dental practice is built on trust, comfort, and personalized care for every stage of life. Whether you need a routine cleaning, a senior dental check-up, or a complete family wellness plan, we're here to help your whole family smile with confidence.
Choosing a family dentist means more than just convenience — it means building a long-term relationship with a dental team that truly knows you. When one office cares for your entire family, you get consistent records, easier scheduling, and a trusted partner for every dental milestone.
From young adults starting their careers to grandparents enjoying retirement, our team welcomes patients of all ages. You'll never have to drive across town to multiple offices.
Dr. Sojung Jang brings over two decades of clinical expertise, with a calm, gentle approach that puts even the most nervous patients at ease.
Digital X-rays, intraoral cameras, and the latest comfort techniques mean faster diagnoses, more accurate treatment, and a relaxing experience every visit.
Located at 410 N. Euclid St., we're easy to reach from Yorba Linda, Brea, La Habra, Placentia, and all of North Orange County. Free parking in the back.
We offer everything your family needs under one roof — so you can stay healthy without juggling multiple specialists.
Life gets busy — but your smile shouldn't be put on hold. Our adult dental services keep your teeth strong and healthy through every stage of your career and family life. We offer routine cleanings, fillings, crowns, root canals, gum disease treatment, and more. Whether you haven't been to the dentist in a while or you're looking for a new dental home in Fullerton, we'll meet you where you are — judgment-free.
As we age, our dental needs change — and so does the level of care we deserve. At Sunny Hills Dentistry, we provide compassionate, gentle dental care designed specifically for older adults. From managing dry mouth and gum recession to crowns, bridges, dentures, and dental implants for missing teeth, Dr. Jang takes the time to understand each patient's medical history and create a treatment plan that prioritizes both comfort and long-term oral health.
Most dental problems are easier — and far less expensive — to prevent than to treat. That's why we believe regular check-ups and cleanings are the foundation of lifelong dental health. Our hygienists use gentle techniques and modern tools to thoroughly clean your teeth, while Dr. Jang performs detailed exams to catch any issues early. We also screen for oral cancer at every visit, because early detection saves lives.
Caring for your whole family's smiles should be simple. We make it easy with coordinated appointments, clear treatment plans, and flexible scheduling — so the whole family can be seen the same day if you'd like. Whether your household has two members or six, we'll create a wellness plan that works for everyone's needs and budget.
Looking for something specific? We also offer Invisalign, teeth whitening, and emergency dental care.
We know that visiting a new dentist can feel a little uncertain — especially if it's been a while. Here's what your first visit at Sunny Hills Dentistry looks like, so you can walk in feeling prepared and at ease.
You'll be greeted by name and offered a comfortable seat in our bright reception area. Our front desk team will help you with paperwork and answer any insurance questions before you head back.
Dr. Jang and our team will take digital X-rays and perform a thorough exam of your teeth, gums, bite, and oral tissues. We'll also screen for signs of oral cancer.
We'll walk you through what we found — using clear language, not dental jargon. If treatment is needed, we'll discuss your options, costs, and timing. No pressure, ever.
You'll leave with a clear understanding of your dental health and a customized care plan. Whether that's a cleaning today or treatment scheduled for next month, you're in control.
With over 20 years of experience, Dr. Sojung Jang has built her practice on a simple belief: every patient deserves to feel heard, comfortable, and confident in their care. She earned her dental degree and has dedicated her career to staying at the forefront of modern, evidence-based dentistry — while never losing sight of the human side of patient care.
We're proud to be the dental home for so many families across Fullerton, Yorba Linda, Brea, and the surrounding communities. Here's what some of them have shared.
"OMG this is the BEST dentist I have ever found. Dr Jang is very attentive to detail — she's done 3 of my crowns and you cannot even tell they are crowns. Her cleanings are exceptional and the office is amazing with TVs on the ceiling so you're relaxed the whole time. With a friendly staff and a great dentist you can't go wrong. I will be back in 6 months and tell all my friends!"
"I have struggled to find a dental practice that I really like in Orange County, and I am so glad that Sunny Hills Dentistry was recommended to me! Dr. Jang and her staff are incredibly kind, patient, and welcoming. I always look forward to my appointments here because I know I will be getting high quality care. I would highly recommend this practice to anyone in need of a great dentist!"
"I really liked this dentist — it was my first time visiting in a while. My first impression was that it was super clean and the dentist and dental assistant were really nice and patient. I had to get fillings and they were gentle and fast. I really recommend coming here."
Your family deserves a dental home that feels welcoming, modern, and genuinely caring. Whether it's been six months or six years since your last visit, we'd love to meet you. Book your appointment today — we can't wait to see you smile.
