LANAP: Gum Disease Treatment
Lasers and Dentistry: The Periolase

When the first working laser was introduced to the world, one observer said “The laser is a solution looking for a problem.” The laser is easily one of the greatest scientific inventions of the twentieth century. Forty years later, lasers are everywhere, from the supermarket to the DVD player.Laser 

The first laser for dentistry was introduced in 1990.  In 1998 two  California  dentists reported the first uniquely laser-dependent dental procedure.  Dr Robert Gregg and Dr. Del McCarthy, after years of research, used a laser for treating gum disease and were able to consistently cause growth of new periodontal attachment.  The laser they developed is called a Periolase.  It is tuned to a specific wavelength, pulse width and power to maximize its IALD logotreatment of gum disease.  It has been submitted to the FDA and received approval for the treatment of gum disease.  The specific treatment protocol, LANAP, was then submitted to the FDA and was approved.  Both the Periolase and LANAP are patented.  Dr. Gregg and Dr. McCarthy then set out to introduce the Periolase to the dental community.  They formed the IALD, the Institute for Advanced Laser Dentistry, as a training Periolaseorganization.  Instead of just advertising in journals and sending them to any dentist that ordered one, they set up a training facility in California  .  After deciding to buy a Periolase, the dentist is given a date to attend training, and at the end of that training session, given a test.  After passing the test, their Periolase is then built and shipped to them.  There are then two additional required training sessions. 

This approach is unique in the dental world.   Because of this, we have had great success with the Periolase and LANAP. 

If you have gum disease issues, we will do a free consultation to see if the Periolase and LANAP are right for you. Click here to request an appointment.

Here is a graphic of the basics of LANAP:


Periolase Graphic


  1. The probe indicates excessive pocket depth. 
  2. Laser light kills bacteria and diseased tissue. 
  3. Ultrasonic scaler uses sound waves to break up and loosen tartar and special hand instruments are used to smooth root surfaces. 
  4. Laser finishes debriding pocket and establishes coagulation. 
  5. The tissue is compressed against the root surface and a stable fibrin clot forms along the gum line. 
  6. The bite is adjusted and equilibrated to prevent excessive (traumatic) chewing forces from interfering with healing. 
  7. Healing with new attachment of the gums to the tooth.

Dear Dr. Dilger:


It all started with my initial phone call to Dr. Dilger's office. I felt so comfortable from the start and after I came in for my first visit it's been all about what I want and what Dr. Dilger and his staff recommends for me. All around, it's been the best dental experience I've ever had.

Going to the dentist used to be a nightmare experience for me. That's all changed when I came to Dr. Dilger. Dr. Dilger's office staff are so warm and welcoming. Visiting them is like going home. Dr. Dilger's calm and caring manner erased all my dental anxiety and for the first time in my life I found myself relaxed in a dental chair. Dr. Dilger and his staff really took the time to get to know me and my concerns. They talked with me about my fears and helped me address my anxiety. Now I visit the dentist and I'm not afraid. I can not express the difference Dr. Dilger has made in my dental life! Thanks so much Dr. D.

I love my new smile.  It was so easy too.  Nearly pain free.  I am considering my lower teeth at a later date.
