Upgrade Your Mouth-Body Connection Reviews & Book PDF Download. This book was a great wake-up call for me about the importance of oral health. I tend to focus more on the food/nutrition side of things and this was a fantastic reminder that the body is connected and functions as a whole, not as separate entities. Your dental health CAN affect other areas of your well being. If you are a person that has had dental work done in the past and are struggling now with dental or even other health issues I highly recommend you pick up a copy of this book, you will likely finally get some answers to your questions and find helpful resources to deal with whatever issue(s) you might be having. I highly recommend this book for anyone looking to improve their overall health.
