The best defense against common dental ailments is regular preventative care. Dr. Barr, Dr. Diachenko, and their dental team are committed to providing you with the most advanced preventive dentistry. Stop problems before they start, and enjoy a lifetime of optimum oral health!

Periodontal Therapy

Though many don’t realize it, 50% of all adults have some form of periodontal disease, the condition that is chiefly responsible for adult tooth loss, bleeding gums, bad breath, and receding gums. However, periodontal disease is easily prevented with proper hygiene, home care and professional treatment from Dr. Barr or Dr. Diachenko. If your complete evaluation reveals that you do suffer from periodontal disease, you will have access to advanced periodontal therapy to heal and restore your oral health. Like many medical conditions, early diagnosis means easier, less invasive, and more effective treatment. Keep on the lookout for these signs and symptoms:

  • Bleeding gums
  • Bad breath
  • Receding gums
  • Loose teeth
  • Pus around teeth


Don’t let decayed, disfigured or discolored teeth keep you from smiling! If you suffer from any of these ailments, you may be a good candidate for composite resins, also known as tooth-colored fillings. Dr. Barr or Dr. Diachenko will remove any decay from the tooth, then replace it with an inert “filling” material. Though amalgam (silver) fillings were used in the past, you can now have tooth-colored fillings that bond to the teeth for a stronger restoration and look great too. This results in a longer lasting, brighter, whiter smile.

Oral Cancer Screenings

There will be 41,000 Americans diagnosed with oral cancer this year, resulting in 12,500 deaths, and the fatality rate from oral cancer is especially high due to late discovery of the disease.  Your dentist is the only medical professional in a position to routinely evaluate and detect abnormalities, so Drs. Barr and Diachenko offer routine oral cancer screenings to you as a patient using the FDA approved VELscope® oral cancer screening system.  As with all cancers, early detection is vitally important. A patient who does not seek regular, continuous care from a dental professional is putting their health at risk by delaying a diagnosis in the early stage of oral cancer.  We are dedicated to providing this potentially life-saving procedure for you.


Do you suffer from headaches or from jaw pain in the morning? Do you have unexplained chipped or cracked teeth? These symptoms mean you could be grinding or clenching your teeth during the night. To keep you from seriously damaging your teeth, we recommend a dental appliance called a nightguard, which protects your teeth from nighttime grinding and clenching. Drs. Barr and Diachenko take great care in making sure you have a proper fit to prevent pain in your jaw joint. Ask your dental team about having a nightguard custom created especially for you.

Mouth Guards

Do you or your children play contact sports? The American Dental Association estimates that mouth guards prevent approximately 200,000 injuries each year in high school and collegiate football alone. Properly diagnosed, designed, and custom fit mouth guards are essential in the prevention of athletic oral and facial injuries. Drs. Barr and Diachenko offer custom made mouth guards for your children that fit properly, are comfortable, resilient, and tasteless and cause minimal interference with speaking and breathing. They are easy to clean and come in many color combinations. If you or your child plays sports or other similar activities, mouth guards are a great way to protect them from concussions and other potential injuries.
