BEFORE and AFTER treatment

Advanced Technology

Dr. Rissin chooses carefully which and when radiographs are taken. There are many guidelines that we follow. Radiographs allow us to see everything we cannot see with our own eyes. Radiographs enable us to detect cavities between your teeth, determine bone level, and analyze the health of your bone. We can also examine the roots and nerves of teeth, diagnose lesions such as cysts or tumors, as well as assess damage when trauma occurs.

Dental radiographs are invaluable aids in diagnosing, treating, and maintaining dental health. Exposure time for dental radiographs is extremely minimal. Dr. Rissin utilizes Digital Imaging Technologies within the office. With digital imaging, exposure time is about 50% less when compared to traditional radiographs. Digital imaging can also help us retrieve valuable diagnostic information. We may be able to see cavities better. Digital imaging allows us to store patient images, and enables us to quickly and easily transfer them to specialists or insurance companies.

Digital X-rays are diagnostic, but they can also be preventative, by helping a dentist diagnose potential oral care issues in a patient’s mouth before they become a major problem. A digital X-ray offers more precision since we view the image on a computer monitor, instead of holding up a 35mm film up to the light. Digital X-rays results in 1/6th the radiation exposure to you.

Digital X-rays are divided into two main categories, intraoral and extraoral. Intraoral is an X-ray that is taken inside the mouth. An extraoral X-ray is taken outside of the mouth. 



Many patients, especially younger patients, are very familiar with the latest technology and are comfortable with the high tech practice. Computers and TV screens are the primary method of information process. Intraoral camera technology that helps enhance your understand of your diagnosis.

An intraoral camera is a very small camera – in some cases, just a few millimeters long. An intraoral camera allows our practice to view clear, precise images of your mouth, teeth and gums, in order for us to accurately make a diagnosis. With clear, defined, enlarged images, you see details that may be missed by standard mirror examinations. This can mean faster diagnosis with less chair-time for you! Intraoral cameras also enable our practice to save your images in our office computer to provide a permanent record of treatments. These images can be printed for you, other specialist, and your lab or insurance companies.


“I was recommended to Dr. Rissin because my whole mouth needed to be restored. I was missing many teeth and looked awful for a person in the public eye. Dr. Rissin planned a dental implant supported reconstruction of my mouth. Dr. Rissin was the “conductor” who coordinated all the treatment required at other offices. My treatment lasted over a year but I was well aware of the time needed before starting and everything went very smoothly and the result is awesome. I can finally smile in public again. Dr. Rissin explained all the procedures so I was aware of what to expect during my care. I would highly recommend him without any reservations.”

“I was petrified of the dentist but needed my front teeth crowned. A friend of mine recommended Dr. Rissin and I couldn’t be happier. He was very patient with me and talked me through all the procedures and always put me at ease. My teeth came out awesome and everyone notices how good I look. I am forever grateful to Dr. Rissin.”

“I was referred to Dr. Rissin by my general dentist because I needed a front tooth replaced with an implant and crown. Dr. Rissin is very detail oriented and my tooth came out awesome. I would highly recommend him to anyone who asked.”

Chris M.

“I have been seeing Dr. Rissin for years. I was referred to him by my general dentist because I needed extensive crown and bridgework done. Dr. Rissin was always very caring and gentle and the result was excellent. When I completed my treatment I alternated my cleaning appointments so Dr. Rissin and my general dentist can check me every year.”
