Digital X-Rays

Digital radiography (digital x-ray) is the latest technology used to take dental x-rays.  This technique uses an electronic sensor (instead of x-ray film) that captures and stores the digital image on a computer.  This image can be instantly viewed and enlarged helping the dentist and dental hygienist detect problems easier.  Digital x-rays reduce radiation 80-90% compared to the already low exposure of traditional dental x-rays.

Dental x-rays are essential, preventative, diagnostic tools that provide valuable information not visible during a regular dental exam.  Dentists and dental hygienists use this information to safely and accurately detect hidden dental abnormalities and complete an accurate treatment plan.  Without x-rays, problem areas may go undetected.

Dental x-rays may reveal:

  • Abscesses or cysts.
  • Bone loss.
  • Cancerous and non-cancerous tumors.
  • Decay between the teeth.
  • Developmental abnormalities.
  • Poor tooth and root positions.
  • Problems inside a tooth or below the gum line.

Detecting and treating dental problems at an early stage may save you time, money, unnecessary discomfort, and your teeth!

Are dental x-rays safe?

We are all exposed to natural radiation in our environment.  Digital x-rays produce a significantly lower level of radiation compared to traditional dental x-rays.  Not only are digital x-rays better for the health and safety of the patient, they are faster and more comfortable to take, which reduces your time in the dental office.  Also, since the digital image is captured electronically, there is no need to develop the x-rays, thus eliminating the disposal of harmful waste and chemicals into the environment.

Even though digital x-rays produce a low level of radiation and are considered very safe, dentists still take necessary precautions to limit the patient’s exposure to radiation.  These precautions include only taking those x-rays that are necessary, and using lead apron shields to protect the body.

How often should dental x-rays be taken?

The need for dental x-rays depends on each patient’s individual dental health needs.  Your dentist and dental hygienist will recommend necessary x-rays based upon the review of your medical and dental history, a dental exam, signs and symptoms, your age, and risk of disease.

A full mouth series of dental x-rays is recommended for new patients.  A full series is usually good for three to five years.  Bite-wing x-rays (x-rays of top and bottom teeth biting together) are taken at recall (check-up) visits and are recommended once or twice a year to detect new dental problems.

Testimonials

Dr. Leong is an amazing dental professional. I've been seeing her for a number of years and she has always been effective, responsive, personable and caring. She managed my Invisalign process and did a great job from start to finish. She's very gentle so pain is never in the equation during my visits with her. She's also just a wonderful person. I consider her both my dentist and my friend. I would recommend her to anyone who's looking for a skilled dental professional.

I have been consistently happy with how Dr. Leong and her staff have cared for my teeth. AND, I've had A Lot of Work for Dr. Leong to do with my teeth! Shortly after my first cleanings, I had cavities to fill, then a molar cracked and I had to get a crown, which Dr. Leong did really well (better than my last dentist for sure!)... Given these positive experiences, I trusted Dr Leong to create Veneers for 8 of my upper front teeth, to totally transform my smile! I am very happy with my smile, get lots of compliments, and have confidence that the work will last me a long time (probably longer than my teeth would on their own... She not only did expert work to prepare my veneers and my teeth, but she also went above and beyond to make sure everything fit and felt right for me.

Dr. Leong is hands down the best dentist I've ever had. She is extremely friendly and knowledgeable. She educated me about the right way to take care of my teeth without being pushy or judgmental. She explained everything she was doing very thoroughly so that I understood my own health better. She never made me feel rushed and she was never pushy trying to sell me dental work I didn't need, which has happened to me many times with other dentists. She and her staff were top notch.

My appointment was exactly on time and Anna at the front desk had already gotten my insurance information without me having to fill out anything. Everything was very well organized and we started my exam right away.
