Dentistry Done Differently

What can your smile do for you?

What can our dental office do for you?

These are two important questions with a very exciting answer. The reason that we are “different” is because we have chosen to place more importance on the healthcare experience of the whole patient as compared to a limited view of the more traditional dental office approach of cleaning and repairing teeth.

Our approach embraces each patient with the goal of helping them feel better during their visit as well as improving their health for a lifetime. Our office doesn’t look, smell or feel like a dental office. We don’t limit ourselves to a small number of traditionally provided dental services and like to offer our patients “one stop shopping” for their dental needs whenever it is possible to do so.

We love helping our patients reach their full potential of having a healthy, happy and attractive smile while using the mouth as an opportunity to improve the entire body.

We are not “normal”, will never be boring and will always be different!


Levels of care

What can your smile do for you?


We offer two different levels of service at Synergy Dental Solutions. 

Some people just want their teeth cleaned, repaired and replaced.

Some are interested in taking advantage of the many years of experience, hundreds hours of training and the cutting edge services offered at Synergy Dental Solutions.  Many of our patients travel many miles to take advantage of Dr. Angie's expertise and care.  Others have been her traditional dental patients for over 25 years.

We welcome patients of all kinds and provide services that many dental offices do not offer.  Our additional training and technology allow us to  serve our patients who are interested in a more comprehensive approach to care including:

  • Biological and Health Focused Dentistry
  • ALF Therapy and functionally based orthodontic care
  • Cosmetic dentistry and facial esthetics
  • Early childhood tongue function, airway management and facial development
  • Treatments for headache, craniofacial pain and sleep disordered breathing/snoring

Preventative and Restorative/Traditional Dentistry



Comprehensive Care


Our Programs for ALF Therapy and Oral FUnction


Customized care for children ages 0-5


In the beginning...

We were created with the innate ability to thrive.  

When unwanted obstacles to natural development occur,  we strive to utilize the tools given to us to overcome those obstacles.  

By optimizing tongue function and supporting the reflex system we honor the "Master Plan"  by mimicking nature's objectives and honoring the principles of human development. 


By striving to create the most natural method of growth and development, our providers can offer minimal  intervention  while offering maximal potential.

Our highly trained team includes our very own tongue function specialist and baby whisperer, Nicole Edwin.  For more information on her services, please click on the button below:

Supporting active growth for ages 6-12


GROWing with the help of ALF Therapy

We believe that the opportunities provided by utilizing ALF Therapy to guide facial growth allow us to support your child in ways where other appliances and techniques often fall short.

The use of the ALF family of dental appliances allows an easy to use system of continuous wear as opposed to removable and part-time wear appliances

 Parents love not having to force their children into wearing uncomfortable removable appliances and/or performing boring exercises. 

Many other dental appliances are both uncomfortable and affect speech, eating and socialization with their peers.

ALF Therapy benefits include:

  • dental therapy fully customized to the needs of your child
  • 24/7 wear to ensure compliance and optimize results
  • support of the child's reflexive system 
  • easy to wear and almost invisible to their friends
  • frequent reports of improved mental focus and physical ability

The decision to care for a child's smile  as they GROW is truly a HEALTHCARE decision.  

Utilizing the appliance designs of ALF Therapy allow providers to harness the potential of Mother Nature

The smile of our children not only has the ability to brighten our day, but also has the potential to improve their lives by applying the basic principles of health and wellness to their facial growth.  Development of the face affects the ability of every person, whether child or adult, to function on a daily basis.   

GROW Therapy provides advantages otherwise not available through more traditional orthodontic options and other dental appliances that negatively affect the ability of the tongue to enhance function and natural growth..  

GROW Therapy is not to be compared to traditional orthodontic services as the methods and techniques of assessment and treatment are distinctively different.

By harnessing the power of Mother Nature, the child has a unique opportunity to grow at their own pace, develop with careful observation and ensure that their precious brain and neurological systems are respected and supported through the entire process of growth and facial development.  

By allowing the brain to connect, nature can take over.

By applying the tips, techniques and tools offered through ALF: GROW, the child will be supported, nurtured and guided through some of the most critical times of their lives


Carefully guided care for ages 12 and over


Navigating the road to resilience

Did you know that approximately 90% of facial growth has been completed by the age of 12?

After the majority of facial development has been completed, we still have the opportunity to guide the patient back to a more ideal function using a natural, principle-based treatment to supplement health. Our Guide program addresses those concerns and supports a comprehensive care approach to ALF Therapy.


The Guide Program address ALF Therapy treatment options related to optimizing oral function to address:

· airway insufficiency/sleep disordered breathing

 *crowded, crooked teeth

· movement disorders

· extraction/retraction orthodontics 

· TMJD, clicking/popping jaw joints and craniofacial pain

What Are Your Basics of Health?


 The ability of the teeth to complement each other during chewing function as well as the effect of dental infections as they impact the entire body is the very first thing that we evaluate. After all, we are a dental office! 


 If the teeth are out of balance, it can affect the muscles of the head and neck, and eventually the entire body. 


 Without proper support of the teeth the jaw joint, also known as the TMJ (temporomandibular joint), the other joints of the body can also be affected. 


 Anyone who has had pain in the mouth, head or neck has witnessed the impact of how the brain interprets a signal of discomfort from the mouth and surrounding areas. The facial area supplied by the most powerful cranial nerve in the body (the trigeminal nerve) is directly responsible for almost 50% of what the brain is processing at any given time. We use our knowledge of this impressive and complicated neurological system to help our patients lead healthier, happier lives. 


 The ability of air to flow from the nose and mouth to the lungs is directly impacted by the structure of the mouth, especially the tongue. We help diagnose potential restrictions in this area and provide solutions to improve the ability to properly breathe and provide oxygen to the body through dental therapies. 

Comprehensive Wellness


 The mouth is where “life” begins. Communication, breathing, eating, drinking and smiling are critical to everyday quality of life. Function and appearance directly affect a person’s feeling of emotional, physical and functional wellness.
