For people with receding gums, tooth sensitivity is a big problem. Conventional grafting procedures to fix receded gums can be painful. Now, an innovative dentist named Dr. Chao has developed a new almost painless way to do it, called the pinhole technique. Instead of cutting, he uses a needle to make a small hole. It can correct 10-14 teeth at once, can take only 30 minutes, and best of all? Only one day to recover. Dr. Chao is still refining his procedure, but hopefully this technique will help a lot of patients get through treatment painlessly and efficiently.
