We are the only dental/medical office in Rancho Cucamonga with a dentist/doctor board certified by the American Board of Orofacial Pain. The medical and dental specialty of Orofacial Pain incorporates the prevention, evaluation, diagnosis, treatment, and rehabilitation of orofacial pain disorders. Patients with these disorders may incur pain and associated symptoms arising from a multitude of causes including postoperative pain or pain associated with a malignancy, or may be syndromes in which pain constitutes the primary problem, such as TMJ disorder pain, neuropathic pain or headaches.
Sleep apnea can reveal its presence in a number of ways, and each patient may have a unique combination of symptoms. Dr. Brien Hsu is the only dentist in Rancho Cucamonga that has been board certified by the American Board of Dental Sleep Medicine. In addition he is the first dentist from the USC School of Dentistry to publish an article in the prestigious Journal of Clinical Sleep Medicine. Many of his patients who cannot tolerate CPAP therapy have benefited from his specially designed oral appliances, which prevents airway blockage.
Abnormalities in the oral cavity are diagnosed thorough clinical history, careful examination, and laboratory studies including culture and biopsy are critical. These methods help us distinguish and manage oral mucosal and osseous lesions of the mandible and maxilla. It is important to understand that many times these abnormalities are non-neoplastic and are oral mucosal growths, inflammation and ulcerations as a result of a developmental (congentital, hereditary, etc.) or a reactive (inflammation, trauma, autoimmunity, etc.) etiology.
"Dr. Brien Hsu has been my dentist for many years. I am by no means a fan of going to the dentist, but I can honestly say my experiences with Dr. Hsu has always been pleasant. I recently moved from California to Texas and there was a time when the 2nd molar tooth in my left lower jaw started giving me a hell lots of pain. I visited a reputable dentist in Plano,tx and he saw in x-rays that that root canal procedure done inside there 15 years ago was not properly completed as a small piece of nerve was still intact. He referred me to two tooth implant specialists because he did not think the tooth could survive the 2nd root canal procedure. Both specialists recommended me to go through a very expensive tooth extraction and implant procedure. I didn't feel comfortable with their prognoses, so I asked the 2nd opinion to my all time favorite Dr. Hsu. After Dr. Brien reviewed my information, I had a consultation with him over the phone. he told me that based on the x-rays and photo's, he could probably save my tooth. I immediately made an appointment and booked a flight to see Dr. Hsu in Rancho Cucamonga, California. After a few hours of work (I'd say the most painless root canal procedure I've ever had), Dr. Hsu was able to save my tooth and placed a temporary cap. I then scheduled my next visit with Dr. Hsu and flew back to Texas. I returned two weeks later, on another flight to California, to have my permanent cap delivered by Dr. Hsu. After everything was done, my pain was gone and my tooth felt great! Not only was Dr. Hsu able to save my tooth, but I saved a lot of money from not doing the implant ... even when I factored in my co-pay and cost of air flights. Dr. Hsu has always been very honest with me and his dental work has always been painless. I really wish his dental office was out here in Texas..."
"Just moved into the area and was looking for a good dentist. At first my insurance sent me to some guy down on Foothill. Needless to say when I stepped out of that office they gave me a laundry list of dental stuff that I needed. I didn't trust that other guy, so I talked to my neighbor. She recommended that I go to Dr. Hsu. The office looks like a five star hotel - plus the girl's here at this office were nice and helpful. Dr. Hsu, the main dentist here is amazing. Very thorough in his explainations and he seemed to genuinely care more about my teeth than killing my checkbook. I ended up just needing a few fillings - quite the contrast from the list of dental crap from the other office. On the day of the filling, Dr. Hsu and staff got me a flick to watch and made sure I was comfortable - the whole procedure was completely painless - and this is coming from a guy who's a total wimp!"
I came here to get a crown done. I delayed getting my teeth fixed due to fear of pain. To my surprise it was a smooth and comfortable process. I didn't feel like i was in a dental office. The office was beautiful like a spa. Dr hsu was very communicative for each process he was doing. I didn't feel a thing! The staff was very accommodating and made me comfortable. I also brought my daughter. She's a toddler. It was her first experience. I was more nervous for her. But she did great even had a sealant done. She had no fear or discomfort . Dr hsu and his staff are great with kids too!
I've been a patient of Dr. Hsu for years and can honestly say he is the most pain-free, efficient and knowledgeable dentist I've ever had. I can go on about the numerous fillings, root canals and caps my troublesome mouth has required over the years staring from my sugar-laced childhood, but I won't bore you. Needless to say, before Comfort Care, I'd seen a multitude of dentists and none of the experiences could be called pleasant- I'd usually walk away with an aching jaw and nightmares of needles attacking my face. I'd consequently built up an intense fear/hatred of going to the dentist. After ducking out for years, I finally had to accept that it was cavities in my mouth causing the pain, and I made an appointment with Comfort Care and headed in. I was mentally psyching myself up for the first and maybe biggest thing I dreaded- the novocaine shot. I'd always remembered these shots hurting like crazy going would move in and then the dentist it around once it was already in and spread the novocaine around, resulting in more aches. Then, even after the shot, I'd sometimes still feel some pain while being worked on, resulting in more shots or being force to bear it. When Dr. Hsu numbed my mouth, I didn't even feel the needle going in. From there, all the drilling and filling was completely painless and surprisingly quick. His work is solid(never had a filling fall out or need fixing like I have with other dentists), and he takes the time to go over procedures and update me as he's working on my mouth. As I said I've been going for years and would highly recommend Comfort Care to anyone, particularly anyone with those childhood needle fears.
"Dr. Hsu has been my family's dentist for many years now. His staff are always friendly and easy to work with. I have had painful experiences with other dentists, but ever since Dr. Hsu has been my dentist, he helped ease my phobias of dentistry and made all my visits comfortable. He's always been very honest with us, being very patient about explaining all the minor details about our procedures. I remember a time when I was looking to do veneers for my front teeth after watching how they were done on Extreme Make-Over. Dr. Hsu had done some veneers for one of my friends and they looked amazing. I decided to asking him about doing the same thing to me. he was very nice and thorough in explaining the the process with both benefits and consequences. He convinced me NOT to do the veneers because he didn't feel comfortable shaving down any of my healthy teeth in order to make them look good. Instead he offered me an alternative - deep bleaching. He was able to make my teeth beautifully white, without having to cut my teeth down! Best of all, he saved me thousands of dollars by not doing the veneers. If there was a way to rate this dentist above 5 Stars, I would definitely do so!
I travel to this dentist for one reason. I believe Dr. Hsu is the best dentist period. He has very gentle hands and pays a lot of attention to making sure we're always comfortable. I don't know how he does it, but his shots never hurt! he doesn't even use that numbing cream before giving me an injection - and I still never feel it. I've even seen him do work on my children - they think he is some kind of magician; their mouth goes numb without them even knowing, his work is fast and painless and then they're out of there-teeth fixed without having any discomfort. When we visit Dr. Hsu and his staff, we always feel warm and welcome. His bedside manners are just so friendly and open, make me feel like he's family. People may think I'm nuts but my family and I actually looks forward to seeing our dentist! It's make really sad to hear about all the medical problems with his baby. I've been reading it on his blog on website. My prayers go out to his family.
I think many will agree that so far the greatest thing about 2021 is that it puts 2020 behind us. We have all endured and have been trying to overcome a multitude of hardships from 2020 – from protests, to wildfires, earthquakes to of course COVID-19. While we started off 2021 with a historic riot, I think with the advent of the COVID-19 vaccine, there is hope that we may reach the end of the tunnel of our pandemic through herd immunity. Many patients have asked if we plan on being some of the first to take one of the U.S. made vaccines … and if so which one?
I’m pleasantly optimistic to say that as of 1/14/21, I have been inoculated with my first dose of the Moderna vaccine. The process was relatively straight forward. I registered for a drive through location, arrived a few minutes early and waited in line in my car. Once I presented my credentials, they asked a few questions and I was given the jab. I was then instructed to park near some medical staff for observation for 15 minutes and released once I reported no side effects.
Day 1 of Moderna Vaccine 1/14/2021: Very mild soreness in my left arm near injection site.
Day 2 of Moderna Vaccine 1/15/2021: Increase to medium/mild soreness in my left arm near injection site.
Day 3 of Moderna Vaccine 1/16/2021: Down to very mild soreness in my left arm near injection site.
Day 4 of Moderna Vaccine 1/17/2021:
I have grown a third arm! My left arm feels fine.
While I believe all the vaccines for COVID-19 will help us overcome this pandemic, many ask why did I choose Moderna vs Pfizier? Below were my reasons as of 1/17/2021:
Moderna’s efficacy rating after the 2nd dose was at 94.1%. While it’s lower than the 95% from Pfizier – one has to remember Pfizier originally published a rate of 90% and then after a few days of Moderna publishing their rate of 94.1%, Pfizier miraculously raised their efficacy of the 2nd dose to 95%...
Moderna’s efficacy after the first dose is between 80-90% efficacy; Pfizier is between 50-60%.
Moderna’s vaccine is stable for up to 30 days in a regular refrigerator or 12 hours room temperature and is ready to dose without dilution; Pfizier is stable for 5 days or 2 hours room temperature and needs to be diluted with sterile 0.9% Sodium Chloride Injection.
Moderna’s side effects per FDA:
- Injection site pain
- Muscle pain
- Joint pain
- Swollen lymph nodes
Pfzier’s side effects per FDA:
- Injection site pain
- Muscle pain
- Joint pain
- Injection site swelling
- Injection site redness
- Feeling unwell
- Swollen lymph nodes
Some people ask why not wait for AstraZeneca-Oxford vaccine? I have more trust in US made health care products and more importantly the efficacy of AstraZeneca-Oxford is at 70.4% - which is quite a drop to 94.1-95%. For my safety and the safety of my patients and family, I would prefer to go for a better efficacy. However please note that 70.4% is still far superior than our annual flu vaccine, which per the CDC is around 40-60%. Although there are no numbers out yet, Johnson & Johnson (another US based company) will soon be out with their own vaccine. The preliminary information reports that this will be a single dose vaccine (vs 2 dose system of Modena/Pfizier) – making it faster to inoculate the United States. Unfortunately, the data on their stage 3 trials are not out and so final efficacy is still in question. IMHO, please stay with a US made vaccine because all their testing data is open to the public and reviewed by an independent panel. In addition, they are better tested, safer and as of now, offer a higher efficacy:
UK: AstraZeneca-Oxford (Reviewed by independent panel, data is open to public)- 70.4% Efficacy
China: Sinovac (1st reviewed by unknown person(s). Second reviewed by Brazil. Data is closed to the public)– started at 78% and now down to 50.38% Efficacy
China: Sinopharm - (Reviewed by unknown person(s). Data is closed to the public) started at 86% and now down to 79.34% Efficacy
Russia: Sputnik V-9 (Self reviewed. Data is closed to the public) started at 95% then went 91.4%, as of January 2021 it’s now down to 73-85% Efficacy
I was never found of going to dentist. lots of fears built up from my past kept me away from seeing one so many years. Dr. Brien Hsu and his staff helped changed all of that. Staff is very nice and accommodating and the dentist - well he's just amazing. Explains everything to me in detail, puts me at ease doing my dental work, is really honest with me, and best of all has never caused any pain to me during my visits. I do't care now how far I have to drive. I have found my dentist for life.
"All I can say is wow what a find in Rancho Cucamonga. I've had my share of dentists in my lifetime from the East Coast all the way to California. This office is great! Staff are polite and friendly. The secret gem is the dentist. Dr. Hsu is such a nice guy and seems to understands all my dental concerns. I didn't believe it was possible but it's true - I felt no pain when he did my filling - I mean nothing! From the shot to the finish..."
"Really cool dentist. Been coming here for many years. I think their new office rocks, makes me feel relaxed. Dr. Hsu is always nice and knows when I feel nervous or uncomfortable during dental work - even before I say a word. I had to change dentists because my company changed my insurance. What a big mistake! The other "dentist" told me I had like 10 cavities and did a ridiculous 2 minute cleaning that hurt like heck. He then wanted to drill the heck out of my tooth the same day. I hauled my @$$ out of that place faster than the guy could blink. Ran back to Dr. Hsu and found out I had zero - nada cavities. Cancelled my dental insurance and I'm sticking with Dr. Hsu."
"Great office, probably one of the best doctors I seen. And this is coming from a guy who's a big wus when it comes to going to the dentist. My gf found this place for me... I didn't believe I could get my teeth worked on without having pain. Dr. Hsu has like really gentle hands and cared about making sure I was comfortable. I guess it also helps that a lot of the girls there are pretty cute too - gotto make sure they don't think that I'm truely a big wus when it comes to dentistry lol."
Okay so I finally grew some balls and decided to get my dental work done! I know I'm a grown man and all, but I just never really liked going to the dentist. Never really found that I didn't want to hurt me...So after a great first visit at this place, I came to get my filling done. And the verdict is...This place rocks! Not only do nurses there baby me, but Dr. Hsu really cared about making me feel comfortable. I have to said this way the most painless dental experience I have ever had...Maybe this will help me grow some bigger juevos and I'll go see the dentist more often!
"The office staff and dentist are very friendly and professional!"
Just moved back to Rancho Cucamonga after being out of state for many years. Needed to find a dentist...Dr. Hsu and Co had great reviews all over the web. Loved my experience here - had a filling done and couldn't even tell that he gave me a shot! Really nice doctor and staff.
I have been a patient for many years and I wanted to let everyone know he is the best Dentist I have ever seen. He is very honest, professional, and caring. My son is special needs and Dr. Hsu and his office is very patient and caring with him. After seeing Dr. Hsu I will not go to any other dentist ever again. I have had horrible experiences with other offices give me the run around, being very unprofessional and trying to change me and my insurance for things not needed. If you want to have a good experience I suggest you go to this office not only is the Dentist the best so is his staff.
"Dr. Brien always does a great job helping me and answering my questions"
"I finally found a Dentist that I can trust and feel comfortable with"
"Very friendly, very thorough"
"This doctor knows what he is doing. Professional, Knowledgeable, and very friendly, Dr. Hsu is the first dentist I have visited who make the process completely painless. Not only does he have good technique, he pays a lot of attention to aesthetics. Yes, I want a dentist who not only makes my teeth healthy but gives me pretty smile!"
Excellent and honest Dentist. Staff here are really helpful and nice. I didn't realize how great dentist I had until my insurance change to a HMO. My new insurance had assign me to another dentist. When I mad my appointment for another office, they said I need lots of dental work. They stared working on one my tooth and hurt me really bad. Came back to Dr. Hsu. He fixed the work that the other dentist screwed up on. I found out that the list of dental work from the HMO office was all BS. I hate my HMO, so now I just pay cash here at Dr. Hsu's office.
"Very Clean & friendly"
"Excellent work! "
"Great, friendly staff, good environment"
I'm Extremely sensitive to pain and Dr. Hsu literally makes all my visits a painless experience.
Kind and friendly staff, comfortable, non-intimidating environment, caring and approachable dentist
Great dentist. Dr. Brien Hsu is very knowledgeable and caring. He explains in detail what's being done to my teeth. I've had cleanings and crowns done and each time I hardly feel anything when he numbs my tooth. I always have a comfortable experience and his assistants are very nice and know who you are. My family and many of my friends come here now too. I highly recommend Dr. Hsu.
The staff is very nice, office is always clean and organized.
