I cannot recommend this dental office highly enough. Finding a dentist that satisfies an entire…read morefamily's needs--and actually makes them look forward to their appointments--is no small feat, but this team manages to do it with ease. From the moment you walk through the door, the atmosphere is welcoming and professional. The front desk staff is incredibly organized, helpful with insurance, and always greets us with a genuine smile. It's clear that patient comfort is their top priority. Why We Recommend Them: Clinical Excellence: The dentists here are truly at the top of their field. Whether it's a routine cleaning or a more complex procedure, their attention to detail and commitment to quality are evident. A Gentle Touch: For those who might have dental anxiety, this is the place to be. They are patient, thorough, and always take the time to explain every step of the process, ensuring everyone feels safe and informed. Family-Friendly Environment: They are wonderful with children and adults alike. They have a unique way of making the kids feel comfortable and brave, which has turned what used to be a stressful chore into a positive experience for our whole household. State-of-the-Art Care: The office is spotless and equipped with the latest technology, giving us total confidence that we are receiving the best modern dental care available. If you are looking for a dental home where you are treated like family rather than just another appointment number, look no further. This is, hands down, the best practice in the area. We wouldn't trust anyone else.

Like many people, dentists aren't my favorite due to past bad experiences, but Tiffany and Dr. Chin completely changed that for me. I needed several procedures done, including cavity fillings, a Tier 2 deep cleaning, and a crown replacement, unfortunately due to a cavity underneath from my previous dentist. Throughout the entire process, the team took the time to explain everything clearly and helped me take preventive steps to ensure my teeth and gums stay healthy. Dental treatments can sound scary and feel frustrating, but the care and attention I received made all the difference. The dental assistants were also extremely kind and attentive, always making sure I was comfortable before and during treatment. I truly felt cared for here and highly recommend this office.

She's super bubbly and doesn't make you feel pressured to make a decision on the spot. Dental hygienist that worked on me was Angie, very sweet, light hands and if I felt sensitivity she stopped. Saw Dr Kao on 4/29/26 and 4/30/26 for fillings, he was friendly, had great stories and added a lot of humor during treatment. Yvette helped him on both days and they work well together. Yvette always made sure I was comfortable, offered me water and headphones to relax, very sweet and easy to talk to. The office now has cherry payments - like Klarna and affirm which is nice because you no longer have to pay a lump sum. Office is immaculately clean.

From my very first phone call with Britney to the warm welcome from Alicia and the whole team, I knew I was in great hands. The office is immaculate, and the state-of-the-art equipment allows everything to be completed in-house, which made the entire experience even more convenient and reassuring. Dr. Sima and Dr. Kao are truly talented dental professionals, and I'm so grateful for the care and compassion everyone showed. Amazing experience! I am definitely recommending all my friends and family to Covina Smile. I am so happy to have found my new dental office!

I've had dental implants done here, as well as deep cleanings in the past, and every experience has been positive. Dr. Lee is extremely knowledgeable, professional, and genuinely caring. He always takes the time to explain procedures clearly and makes sure I'm comfortable, which I really appreciate--especially with more involved treatments like implants. The office staff are also wonderful--friendly, helpful, and well organized. The whole office has a calm, welcoming atmosphere that makes dental visits much less stressful.

Recently, one of my implant teeth became swollen, and they were able to schedule me right away--even offering a same-day appointment before they closed. For urgent situations, they really do their best to accommodate you as quickly as possible. Dr. Joseph's technique is still incredibly professional and gentle, and the treatment was done with very minimal pain. His skills are truly outstanding! The front desk staff is also very friendly and welcoming. I've recommended many friends and clients to this clinic, and everyone has had excellent experiences!
