How Fast Do Teeth Really Move? The Truth About “Fast Braces” and Orthodontic Treatment Time

8 February 2025

If you are considering orthodontic treatment, you have probably seen claims about fast bracessix-month smiles, or aligners that promise a perfect smile in record time. Naturally, this raises an important question: can orthodontic treatment really be made faster?

The short answer is this: tooth movement follows biology, not marketing. Teeth do not know which type of braces or aligners you are wearing. Instead, treatment time depends on how the body responds, how the treatment is planned, and how efficiently it is carried out.

In this article, we explain how teeth really move, what truly affects treatment time, and why “faster braces” are often misleading.


How fast do teeth move during orthodontic treatment?

On average, teeth move at a rate of about 1 millimetre per month. This is a biological limit and applies regardless of whether you are wearing metal braces, lingual braces, or clear aligners.

However several factors influence this rate, which is why treatment times differ from one patient to another.


What factors affect how long orthodontic treatment takes?

Type of orthodontic appliance

Fixed braces, including traditional and lingual braces, usually provide a very secure grip on the teeth. As a result, they allow precise and steady tooth movement.

Clear aligners are also highly effective. However, some complex movements can be less efficient with aligners, which may slightly increase treatment time in certain cases.

That said, no appliance can bypass biology.


Patient biology and age

Age plays a role. In general, teeth move slightly faster in younger patients because the bone is less dense.

In adults, tooth movement can be slower. In addition, certain medications, hormonal factors, or medical conditions may also influence the speed of movement.


Treatment planning and orthodontist expertise

This is one of the most important factors.

An experienced orthodontist plans treatment carefully to:

  • Avoid unnecessary movements
  • Use efficient biomechanics
  • Prevent “round tripping,” where teeth are moved in the wrong direction before being corrected

Better planning means smoother progress and fewer delays.


Are some braces really faster than others?

This is where marketing often conflicts with science.

Many orthodontic products and direct-to-consumer brands claim their systems are faster than others. However, there is no strong scientific evidence to support these claims.

Common misleading claims include:

  • “Six-month braces”
  • “Self-ligating braces are faster”
  • “Clear aligners work in half the time of braces”

In reality, the only way to significantly shorten treatment time is by compromising the result. This may lead to:

  • Incomplete correction
  • Unstable tooth positions
  • Long-term bite problems

Fast treatment is not beneficial if the final result is poor or unstable.


Can anything safely speed up orthodontic treatment?

Over the years, many methods have been promoted to speed up tooth movement. Most do not deliver meaningful results.

Vibration devices and light therapy

Devices using vibration or light stimulation claim to accelerate treatment. However, scientific studies show little to no real reduction in treatment time.


Surgical procedures such as corticotomies

Minor surgical procedures can temporarily increase the rate of tooth movement. However:

  • The time saved is usually only weeks or a few months
  • Costs are higher
  • Surgical risks must be considered

For most patients, this approach is not necessary.


What is the best way to achieve efficient orthodontic treatment?

The most reliable way to keep treatment time as short as possible is not a special device or brand. Instead, it involves:

  • Accurate diagnosis from the start
  • Choosing the right appliance for the specific case
  • Careful planning to avoid unnecessary movements
  • Regular monitoring and adjustments

In other words, good orthodontics is efficient orthodontics.


How long does orthodontic treatment usually take?

Treatment time depends on how complex the problem is.

As a general guide:

  • Mild cases: 6–12 months
  • Moderate cases: 12–24 months
  • Complex cases (crowding, bite problems, extractions): 18–30 months or longer

In general:

  • More complex problems take longer
  • Adults may take slightly longer than teenagers

Final thoughts: choose quality, not “fast braces”

It is understandable to want the fastest possible orthodontic treatment. However, safe, stable and high-quality orthodontic results take time.

The experience and skill of your orthodontist have a far greater impact on treatment time and outcome than any specific brand of braces or aligners.

If you are considering orthodontic treatment, focus on choosing an orthodontist who prioritises:

  • Accurate diagnosis
  • Ideal results
  • Long-term stability

In orthodontics, doing it properly once is always better than doing it quickly and having to fix it later.
