“Does orthodontic treatment weaken teeth?”

This is a question we often hear from patients. It’s natural to worry that since orthodontics involves moving teeth, it might place stress on the teeth or bones. Here, we address that concern.

Why does malocclusion occur?

First, we need to consider the premise: “Why is orthodontic treatment necessary?”

• Genetic factors: Cases involving protruding teeth, underbites, or jaw asymmetry due to skeletal structure.
• Environmental factors: This has become particularly significant in recent years. Modern children tend to have smaller faces and narrower jaws, often lacking sufficient space for teeth to align properly. While tooth size has remained largely unchanged from the past, the reduction in jaw size has led to an increase in malocclusion.

Additionally, increased mouth breathing due to allergies or rhinitis, which lowers the tongue position, further exacerbates misaligned teeth.

The Effects of Orthodontic Treatment on Teeth and Bone

Orthodontics applies force to teeth, promoting movement by “remodeling” the surrounding bone.

• Excessive Force This can damage teeth and bone, potentially leading to tissue loss.
• When tissue is naturally thin If there is insufficient gum or bone tissue, the risk of teeth sinking during movement increases.

Therefore, “accurate diagnosis” and “setting appropriate force levels” are critically important.

Essentials for Post-Treatment Stability

“Aligning teeth” is merely the first step in orthodontic treatment. What matters most is stability after treatment.

• Retention (Retainers) Teeth have a tendency to shift back to their original positions, so wearing retainers for a specific period after treatment is necessary to stabilize the results.
• Augmentation Procedures for Surrounding Tissue When bone or gum tissue is thin, adding augmentation procedures as needed enhances long-term stability.

From Actual Clinical Practice

Simply “aligning teeth” increases the risk of relapse.

However, when diagnosis considers breathing patterns, tongue position, and lifestyle habits, combined with appropriate treatment, orthodontic treatment does not weaken teeth. Rather, by improving bite balance and enhancing cleanability, it expands the potential for long-term tooth preservation.

Summary

Orthodontic treatment does not “weaken teeth”; when performed correctly, it is a treatment that protects teeth.

The key factors are appropriate force application, precise diagnosis, and consideration for post-treatment stability.

We believe that creating the optimal plan tailored to your individual oral condition is the most effective way to ensure your teeth last a lifetime.
