The Zak Dental 360 Degree Quality Control Method:

We don’t just talk the talk…We walk the walk when it comes to Quality Assurance!!!

1.We have a Wellness Doctor on staff at every one of our locations. The sole purpose of this Doctor is to understand your unique oral health needs, objectives, and budget. Once your Wellness Doctor understands your needs, he creates a customized treatment plan that is unique to you. Based on the treatments needed, the Wellness Doctor will build a clinical team consisting of a hygienist, treating dentist, and possible specialists to execute the agreed upon family dental plans.
2.There is always more than one provider working on your treatment plan to confirm the accuracy of your diagnosis.
3.We practice a team-based approach to dental care because dental care requires a vast array of skills and abilities. In nearly thirty years of practice, Dr. Zak has never met a true “Master of All Trades” dentist. That is why we have paired up with a team of specialists that include: periodontists, endodontists, prosthodontists, oral surgeons, and orthodontists to support our general team and step in for more complex procedures.
4.We have a 360-degree quality control protocol in place where at the end of your treatment your Wellness Doctor steps back in to check the quality of the completed work.
