When to Start or Treatment By Twelve’s™

One of the most commonly asked questions of Orthodontists by parents, patients and even dentists is “When should a patient first visit the orthodontist?”

The American Association of Orthodontists and The American Dental Association join in the suggestion that patients first visit the orthodontist at age 7. We agree but many people are cautious to visit for fear of starting “too early”.

Dr. Grob shares this concern and has devoted several years researching, publishing and practicing the Treatment by Twelve’s philosophy. For simplicity, the philosophy puts patients into 3 separate groups based on the tooth eruption chart shown below. SO JUST COUNT THE TEETH!

This philosophy is based on the research of noted orthodontic educators Gianelly, Proffit and others.

The FIRST TWELVE PERMANENT TEETH erupt between the ages of 6 and 9

The NEXT TWELVE PERMANENT TEETH usually appear between ages 10 and 14

The FOUR TWELVE YEAR MOLARS are fully in place by about age 15 and beyond
