How Braces and Aligners Actually Work: The Science Behind a Straighter Smile

At Dr Berera’s dental practice in Leichhardt, we believe that a confident, healthy smile starts with understanding your treatment options. Braces and aligners are two of the most effective solutions for correcting crooked teeth, misaligned jaws, or uneven bites. But how do these orthodontic treatments actually work? Let’s explore the science behind them!

Why Do Teeth Move?

Teeth aren’t fixed in place—they’re held in position by a soft tissue structure called the periodontal ligament, which cushions them within the jawbone. When gentle pressure is applied over time, this ligament adjusts, and the surrounding bone reshapes itself, allowing the tooth to move. Both braces and aligners utilise this natural process, called bone remodelling, to gradually reposition your teeth.

Braces: The Classic Option

Traditional braces consist of brackets, wires, and sometimes elastic bands, working together to realign teeth.

1. Brackets:
   Small metal or ceramic brackets are attached to the front of your teeth, serving as anchor points.

2. Archwires:
   A thin wire connects the brackets, applying controlled pressure to guide the teeth into their new positions.

3. Elastic Bands (Optional):
   In some cases, rubber bands are used to correct jaw alignment and bite issues.

4. Adjustments:
   Every few weeks, adjustments are made to the wires or bands to maintain progress.

Braces are highly effective for treating complex orthodontic issues, and they remain a trusted solution for patients of all ages.

Clear Aligners: The Modern Alternative

For patients seeking a more discreet option, clear aligners like Invisalign offer a customised, removable treatment.

1. Digital Scanning:
   Using advanced 3D technology, a digital model of your teeth is created to map out the treatment plan.

2. Custom Aligners:
   A series of clear plastic trays are made to fit snugly over your teeth, each designed to shift them slightly.

3. Wearing Schedule:
   Aligners are worn 20–22 hours a day and changed every 1–2 weeks to gradually move your teeth closer to the desired position.

4. Convenience:
   Unlike braces, aligners can be removed for eating, drinking, and brushing, offering flexibility for your daily routine.

What Happens During Treatment?

Both braces and aligners rely on your body’s natural ability to adapt and heal. When pressure is applied to a tooth:

• Bone on one side resorbs: This makes room for the tooth to move.

• Bone on the other side forms: This stabilises the tooth in its new position.

This process is slow and steady to ensure long-lasting, healthy results.

How Long Does Treatment Take?

The duration of treatment varies based on the complexity of your case:

• Braces: 18 months to 3 years

• Aligners: 6 months to 2 years

At our Leichhardt clinic, Dr Berera will create a personalised treatment plan to suit your needs and lifestyle.

Which Option is Right for You?

The choice between braces and aligners depends on your specific orthodontic needs. Braces are often ideal for complex cases, while aligners work well for mild to moderate corrections. Dr Berera will guide you in selecting the option that best fits your goals.
