We have had such a wonderful experience with Dr. Biagotti and the team. They did a wonderful job creating a new set of dentures when my father’s were lost at his skilled nursing facility. They look so like his real teeth and fit him perfectly. You cannot tell he has an upper denture. It was not an overnight process, but the process was worth it to get the best fit and look possible. My dad is smiling more and has not problems eating what he wants.

The entire team at Dr Biagiotti’s office is amazing and they at very accommodating when things come up.  He is a true professional and genuinely cares about you as a customer not just another patient to get in and out…. These days too many medical professionals just don’t give that personal attention and TLC.  They also see all ages so it makes it great if you need to bring younger children at the same time to have the entire family go to one place versus children’s dentist and and adults dentist. Another bonus that the kids love is the TVs while you have your cleaning and Dr B will change it to Disney channel for the kids.  They all make sure everyone feels comfortable when here.  THANK YOU DR B!  Also wanted to say MICHELLE who always takes great care of us from the office team is always on top of things and will work with your schedules to make things happen. HIGHLY RECOMMEND THIS PLACE!!!

I highly recommend Dr. Guy Biagiotti. He is very friendly and effective in his work. He explained everything to me and made sure that I feel comfortable and pain free.

His staff, Michelle and Rev are always kind and helpful and like a family to me.

Thank you and I’m looking forward to my next visit.

Very friendly and professional staff and dentist. I’ve been going there for 2 years since my dental insurance changed and have no complaints. The hygienist does a great job too. I recommend this office.

I am so lucky to have Dr. Biagiotti as my dentist. He and his entire staff are always very knowledgeable, courteous and helpful, and they never push unnecessary services or procedures. The care they show to you during your visit is second to none. I am an admitted dental slacker when it comes to flossing, but thanks to his guidance and care, my teeth have never looked or felt better.

Today, I fractured one of my lower molars (leaving an old filling exposed). They took me in right away, and I had my replacement crown completed in one hour. They were ready and waiting for me when I arrived. While that situation is not something anyone wants to deal with, they made it easy and did a fantastic job (minimal discomfort, no pain at all).

If you need a great dentist to care for you, are local to the Tustin area, and don’t require an expensive “spa-like” office that wants to upsell you on everything, I highly recommend Dr. Biagiotti – he’s the man.

Dr. Biagiotti has been my dentist for 20 years.  Not only is he the best dentist but he also has the best office staff. I actually enjoy going to the dentist and my teeth look great. I never have to wait too long and I don’t feel like I’m being over charged. Friendly, clean, professional are a few adjectives I can use to describe this office. If you are looking for a dentist- I stand by my review.

Great dentist! My husband and I have been going to him for years. He has a very calm demeanor and never pushes a “one size fits all” approach to his patients and recommends procedures based only on your personal circumstances, needs, teeth goals, etc. Office is clean and staff is very friendly.

Doctor Biagiotti and his staff are great. I just moved to Tustin recently and had some tooth pain. They brought me in right away. I’ve been to more dentists than I can count and I can’t remember a time when there was no pain throughout the visit. Doctor Biagiotti uses a special type of needle when giving novocaine that causes minimal discomfort. Thanks so much!

Dr. Biagiotti is the best dentist you will ever find. No pain dentistry,
friendly doctor, honest, and an efficient staff with a smile. He has been my dentist for many years.

Great with scheduling, no wait time, super friendly staff, patient with explanations, would definitely refer.

Great staff, lots of personal attention, easy to make appointments. Dr. Guy often cleans my teeth himself!

I’ve been living in OC for 12 years. Dr. Biagiotti’s practice is by far the best I’ve been to. His staff is friendly and prompt. When they bring you back, they immediately begin your cleaning. Finally, a doctor who respects your time as much as his own! I feel like they really LISTEN to the patient. I highly recommend Dr. Biagiotti!

Stephen B. from Tustin, CA (Source: Yelp)


I didn’t go the dentist for 10 years. I was afraid to find out how much damage I had caused and I was afraid of getting lectured. Dr. Biagiotti was highly recommend by a close friend, and he lived up to the hype. He was kind, extremely knowledgeable, and thorough. He made me feel comfortable and treated me with respect. I would highly recommend him to anyone who is fearful of dentists, or to anyone who just wants a great dentist.

Best dentist and dental office EVER. I tell everyone I know to go to Dr. B and my whole family are patients there! Wonderful practice!

Andrea W. from Costa Mesa, CA (Source: Yelp)


Simply the best! Without even a hint of hesitation, I can recommend Dr. Biagiotti and his team. They are wonderful! After about 10 years under Dr. Biagiotti’s care, I had to an insurance change and had to see another dentist. I won’t go into great detail, but after never needing extensive work to my mouth in my life, this new dentist informed me that I’d need, two crowns, four fillings, a deep clean, and a mouth guard–all amounting to (a lot of money). Panicked, I immediately took my x-rays back to Dr. B. and was reassured that I did not need that work done. He is conservative, and trust-worthy and I’d rather pay out of pocket for someone I can trust than utilize my insurance and have work that doesn’t need to be done. If you’re searching for a new dentist, see him! You will be so happy you did.

I was referred to this dentist by my husband after having some less than memorable experiences somewhere else. This dentist is very informative, does a job well done and his staff is also very professional but still friendly. He has openings for emergencies like when part of my filling was coming off, he took me in the next day at a convenient time for me. This office is spot on for a dentist and they even have a kids little section in case it needs to be used which it has by my little girl the last time I went in for a cleaning. He doesn’t try to rush you to get a service done and does not sale you on anything you don’t need like I had been done in the past at other places. I really like the family vibe this place has and look forward to coming here. I also like that his reminder appointment cards have a tooth shape sticker that you can put on your calendar. Its in the details! Overall, I am very happy I was recommend to him and will continue to come back.

My husband and I have been with Dr. Biagiotti for the past four years. His office staff is so professional, very accommodating. Our hygienist is so thorough, teeth feel so clean when we leave. My husband has had more intensive work done, and has been extremely pleased with the quality of care. They really define what a “gentle” dentist should be!

Great Dentist! Very quick and efficient w/ all procedures. I also very much appreciate his Saturday hours. Everyone that works here is friendly and helpful.

Dr. Biagiotti is the most gentle dentist I have ever been to. He is very cautious and careful about not scraping my gums and causing bleeding. Since I have a blood clotting disorder, this has been a gift for me!

Dr. Biagiotti and his staff are excellent at what they do! I have been going to them for years.

I have traveled allot over my life so I have had allot of dentists. DR. Biagiotti is the best, most gentle dentist I have ever been to. I don’t mind going or avoid out until I’m in more pain than the visit will bring any more and I’m healthier for it. If you don’t have a dentist, go see him!
