Getting orthodontic treatment takes time, and that wait can feel endless. You want straight teeth but also want to know how long it will take. The timeline varies based on age, the type of correction needed, and how well you follow the therapy plan. If you are looking for an orthodontist in Silver Spring to address your concerns or are already undergoing treatment, you may be curious about the process. Understanding the average duration for different age groups helps set realistic expectations.

How Age Affects Treatment Time

Your age plays a significant role in how long oral procedures last. The younger you are, the easier it is to move teeth into place. Let us break it down: 

Phase 1: Early Dental Treatment (7-12 Years Old)

Phase 1, called interceptive treatment, is for children whose permanent teeth have not fully developed. 

At this stage, early intervention helps correct existing or potential problems before they get worse. Treating issues early can prevent more abrasive procedures later. It also reduces the total duration of the procedure, making phase 2 easier or even unnecessary in some cases. 

This stage usually lasts 6 to 18 months. Routine checkups help determine when the next phase should begin. The American Association of Orthodontists (AAO) suggests that children see an orthodontist for evaluation by age seven. 

Phase 2: Full Dental Treatment (12-18 Years Old)

Phase 2 begins when almost all the adult teeth have erupted. This stage focuses on the final alignment using braces, aligners, or other orthodontic tools. The goal is to ensure proper jaw function, prevent discomfort, and improve overall appearance. 

Most treatments in this phase last 12 to 20 months, but this varies depending on the patient’s oral complexity. 

Phase 3: Orthodontic Treatment For Adults (18 Years And Older)

Phase 3 usually lasts 18 to 30 months, but severe conditions take longer. Since the jaw is fully developed, moving teeth requires more time and effort. Adults often opt for aligners as they offer a discreet way to straighten teeth without the hassle of wires and brackets. 

However, traditional braces are recommended for severe misalignment. 

Consistency in wearing aligners or following brace adjustments contributes to the therapy’s success. Regular checkups help track progress and make changes if required. 

Factors That Slow Down Treatment Time And Results

Besides age, several aspects impact how long you wear your orthodontic appliance. They are:
