I have been a patient of Dr. Chan for a while. Back in 2016, I had a tooth with an infected root canal. It was part of a bridge. and the other anchor tooth also showed infection. I had this constant nagging discomfort but I didn’t want to remove the teeth. I started with Dr. Chan’s circulation therapy averaging about 2-3 times a week. I realize this is not what is recommended because in my condition, I need 2 therapies a day everyday, but a 2-3 therapy a week is better than not having any at all. Sometime around the fifth month, I was still experiencing the discomfort and felt quite frustrated. Dr. Chan told me to be patient and just keep coming. I did feel better after each session so I continued to show up for therapy. Thirteen months later, Dr. Chan took new x-rays of my teeth and they showed a remarkable difference. Bone has grown back where the infection used to be. Both teeth, one with root canal and the other without, have been feeling great. I no longer have the nagging feeling of discomfort. My gums look good as well. I am very encouraged and pleased. Thanks to the circulation therapy. I highly recommend it to anyone who believes there is something in their health that needs improving. If I had been getting the therapy twice a day everyday the results I believe would have been realized a lot sooner.
