Is Invisalign Safe? Things You Need To Know

Is Invisalign Safe?

Invisalign has revolutionised orthodontic treatment, with over 12 million smiles transformed worldwide. The treatment’s excellent safety record stems from several key factors:

Medical-Grade Materials

Invisalign aligners are crafted from SmartTrack®, a proprietary thermoplastic material specifically developed for orthodontic treatment. This material is:

• BPA-free and phthalate-free
• TGA-approved for long-term dental applications
• Biocompatible with oral tissues
• Designed for gentle, precise tooth movement

Unlike traditional metal braces, Invisalign aligners contain no metals that might trigger allergic reactions, making them suitable for patients with metal sensitivities.

The Comfort Advantage

Beyond safety, Invisalign offers significant comfort benefits:

• Smooth edges designed to prevent irritation to cheeks and gums
• Removable aligners for easy cleaning and maintenance
• No emergency visits for broken wires or brackets
• Gradual, controlled tooth movement minimising discomfort

Invisalign During Pregnancy

Many expectant mothers wonder about the safety of continuing or starting Invisalign treatment during pregnancy. Here’s what you should know:

• The materials are safe: Invisalign’s medical-grade plastic doesn’t release harmful chemicals that could affect pregnancy.
• Treatment flexibility: The removable nature of aligners allows for comfortable wear during pregnancy.
• Hormonal considerations: Pregnancy hormones can sometimes affect gum health and tooth movement, which our dentists will monitor carefully.
• Timing options: Some patients prefer to begin treatment before pregnancy or after delivery, but continuing throughout pregnancy is generally considered safe.

We recommend consulting with both your obstetrician and our dental team to make an informed decision based on your individual circumstances.
