National Show Your Smile Month – May 2025

National Show Your Smile Month, celebrated in May, was created by John Chao — the dentist who found a way to fix receding gums, using the Pinhole Surgical technique. The holiday raises public awareness about receding gums and other gum-related issues. It also encourages everyone to feel confident about their teeth and show their smile. Many believe that gum recessions only affect seniors, but that is a myth. They affect people of all ages. The good news is that people with gum recession have many treatment options, including the Pinhole Gum Rejuvenation treatment which does not require gum grafting surgery.

History of National Show Your Smile Month

National Show Your Smile Month was created by Dr. John Chao, the inventor of the Pinhole Gum Rejuvenation technique. The date on which the holiday was created is unclear, however, Dr. Chao’s remarkable life and medical career are truly page-worthy. Chao was born in China but emigrated as a young boy with his family to the United States during World War II. He graduated from high school and then the USC School of Dentistry in 1967. Immediately after his graduation, Chao opened his own dental practice in Monterey Park.

In the late 1990s, Dr. Chao attained a law degree from Southwestern Law School in Los Angeles while maintaining a full-time dental practice. In 2000, he introduced the Pinhole Surgical technique. The method was minimally invasive and did not require cutting the tissue, unlike gum grafting.

In 2012, Dr. Chao’s Pinhole Surgical technique was published in the International Journal of Periodontics and Restorative Dentistry, and somewhere along the line, Chao started National Show Your Smile Month to advocate for healthy dentition. He wanted people to be aware of the new method of correcting receding gums without conventional gum grafting surgery.

In 2013, the Pinhole Academy was established, to train and grant licenses to dentists in the Pinhole Surgical technique. Today, John Chao D.D.S. has trained over 3,000 doctors in the Pinhole procedure which is available across the U.S., Canada, Europe, Asia, and South America.
