"I've had a horrible toothache for the last week. I called Dr. Barsoum's office in Chino on Wednesday because the pain was too much. I left work early and headed straight to my appointment. Dr. Barsoum quickly discovered the source of my pain, prescribed meds, and recommended I see the oral surgeon to have one of my wisdom teeth extracted. He called me a few hours after I left the office to see how I was feeling and gave me his cell phone number in case I had any questions or felt any discomfort. I had my tooth extracted by Dr. Cheung in Upland Saturday morning. He explained everything and made sure I was comfortable. The dental assistant put Chapstick on my lips before Dr. Cheung got started and put Vaseline on my lips throughout the procedure. No dry or cracked lips here. I felt zero pain during the process and haven't been in any pain since I got home. He called me this evening to see how I'm feeling and gave me his cell phone number in case I have any questions or need anything. This is by far the best dental experience I've ever had and I am looking forward to getting the rest of the work I need done at Barsoum Dental. Thank God for people who care about the work they do and the people they serve."

About Maxillofacial and Oral Surgery
Oral surgeons are amongst the most highly trained of all dental specialists. However, they are far more than just a dentist as oral surgeons focus on the entire maxillofacial region. These specialists focus on the diagnosis and surgical treatment of a wide range of problems affecting the teeth, jaws, mouth and face. In this way, oral surgery can be used to improve both the function and appearance of the mouth and face.
As specialists in both precision surgery and advanced dentistry, oral surgeons must undergo many years of training in order to become certified. Following four years of dentistry school, oral surgeons then undergo anywhere from four to seven additional years of surgical training in a hospital residency program. During this time, oral surgeons learn general surgery, cosmetic surgery, anesthesiology and numerous other key skills that allow them to perform a wide range of complicated surgical procedures.
At Barsoum Dental, we are proud to employ some of the most respected oral surgeons in Southern California. Tooth extraction, sedation dentistry and dental implants are just a few of the many ways our team can help you to achieve your oral health goals. In addition, we also specialize in cosmetic and reconstructive surgeries, treatment of facial injuries and trauma, cleft palate surgery and surgical treatment of TMJ. Our specialist team also has years of experience in helping patients to overcome their sleep apnea problems, and we may be able to help you finally sleep peacefully throughout the night.
The vast majority of oral and maxillofacial surgery procedures are incredibly complex, which means that it's important that you don't trust your oral health to just anyone. In this sense, Barsoum Dental is an outstanding choice thanks to our combination of highly experienced surgeons and dedicated professional support staff.
