Minimally Invasive Gum Recession Treatment

For patients with gum recession, Dr. Setya performs minimally invasive gum grafting procedures to restore your natural gum line. A restored gum line not only enhances the beauty of your smile, it preserves the health of your teeth by protecting them from damage and decay.

Dr. Setya uses micro-surgical instrumentation and advanced gum grafting procedures. This makes the treatment much more comfortable and healing time faster than with traditional methods.

One method used is the breakthrough Chao Pinhole® Surgical Technique. This minimally invasive technique requires no cutting, suturing or tissue grafting. This procedure allows Dr. Setya to treat multiple areas and complete the procedure in just one visit.
