In this article, our team will address five frequently asked questions about Invisalign Sydney.

What are invisible aligners?

Invisible aligners, also known as clear aligners or Invisalign Sydney, are custom-made, removable trays that gradually move your teeth into the desired positions. The aligners are typically made of a smooth, BPA-free plastic material, making them comfortable and nearly invisible when worn. The treatment involves a series of about 14 aligners that are worn for a specified duration, typically two weeks per set, before moving on to the next in the sequence.

Using 3D scanning and computer modelling technology, our dentists create a personalised treatment plan that maps out the precise movements your teeth need to make. Each aligner applies gentle pressure on specific teeth, gradually shifting them into alignment. Patients must wear the aligners for at least 20-22 hours a day to achieve optimal results.

Who is a suitable candidate for invisible aligners?

Invisible aligners are an excellent option for addressing various orthodontic issues, including mild to moderate crowding, spacing, overbite, underbite, and crossbite. However, they may not be suitable for everyone. Complex cases or severe misalignments may require traditional braces or other orthodontic treatments.

Candidates for invisible aligners are adults and responsible teenagers who can commit to wearing the aligners consistently. Compliance is crucial for the success of the treatment. Additionally, individuals with excellent oral hygiene habits are better suited for invisible aligners since they need to remove the aligners before eating and drinking (except water) to prevent staining and cavities.

Are invisible aligners uncomfortable?

Most patients report minimal discomfort during their invisible aligner treatment. When you switch to a new set of aligners, you may feel slight pressure or soreness for a day or two as your teeth adjust to the new alignment. This sensation is a sign that the aligners are working as intended. Over-the-counter medications like ibuprofen and warm salt water rinses can help alleviate any temporary discomfort.

How long does the treatment take, and can the process be accelerated?

The duration of invisible aligner treatment varies depending on the individual case. On average, it takes about 6 to 18 months to achieve the desired results. However, some cases may require a shorter or longer treatment period.

To expedite the process, patients must strictly follow their dentist’s instructions and wear the aligners consistently as directed. Some aligner brands also offer accelerated treatment options using innovative technologies like high-frequency vibration or specialised materials.

How much do invisible aligners cost, and is the investment worth it?

The cost of invisible aligners depends on various factors, including the complexity of the case and the brand of aligners used. But don’t worry; our team will always disclose the estimated cost of your treatment to you at your first consultation.

The investment in invisible aligners is often considered worthwhile for those seeking a discreet, convenient, and effective orthodontic solution. Straightening your teeth can improve your oral health, boost your self-confidence, and enhance your overall well-being.
