    Dr. Yen is the best dental implants periodontist in SoCal, he has superb knowledge, skill and…read moreexperience, plus he's very witty and friendly, both my husband and I couldn't thank Dr. Brent Lew enough for referring such a caring, thoughtful and intelligent specialist for our dental implants consultation and treatment. We're also surprised and grateful that Dr. Yen, treated us like family, constantly trying to save us money, he tirelessly and patiently explaining to my husband, twice I think, how and why treating three different areas in one visit, saving at least $2,300 than what my husband's brother suggested better to split into three or more different visits. Dr. Yen called and checked on me @ 7:00 pm tonight, after he saw more patients after he extracted, cleaned, and bone grafted my #30 tooth, and cleaned #31 all done by 4:00 PM (in less than an hour), I am so impressed, he kept me informed of the different types of surgery procedures all throughout the surgery, I only felt very minimal pain from the local anesthesia needle, no pain, no swelling, no bleeding as far as I could tell, how's it possible? The lengthy instructions clearly stated to use ice packs, 10 mins on 10 mins off for first 24 hrs (3 packs were provided), then warm heat packs for next 24 hrs to break up swelling and minimize bruising, I tried for less than 30 mins while driving home post surgery, then stopped, since there's no need, no swelling, no bleeding, and no bruising at all. I am so thankful for Dr. Yen's incredible expertise, and Dr. Yen is so humble, he asked me how do I know he's done such an amazing job? I think it's quite self explanatory, when those possible bad/worse/worst scenarios are not happening to me, Dr. Yen has done a fantastic job! Right?

    I am so grateful to have been referred to Dr. Yen. The results have been superb!…read more His gentle demeanor, and caring professionalism, are matched by his outstanding surgical skills and clarity in explaining procedures and likely outcomes. While I hope further work from his skilled hands will not be necessary, yet without question I would seek his service. Dr. Yen, may God continue to grace you and your office. It is a true joy to know you. Rob W

It's been 7 hours post-op and she has had zero pain and hasn't even needed any pain medication yet. That alone speaks volumes about the skill and precision of Dr. Jun. We also appreciated that he personally called to check on her after the surgery-a rare and thoughtful gesture that really stood out. His front office staff (I wish I remembered her name!) was so warm and personable, helping put me at ease as a very nervous mom. From start to finish, the experience was smooth, professional, and full of genuine care. We highly recommend Dr. Young Jun and his team for anyone needing oral surgery! Thank you Dr. Jun.
