The increasing curiosity and interest in clear aligners stem from their numerous benefits. In this comprehensive guide, we discuss clear aligners, how they work, their advantages, and what you need to know to decide if they are the right choice for your smile transformation.

Orthodontic treatments have long been associated with the traditional braces – metal brackets, wires, and occasional discomfort. While braces are undoubtedly effective, an alternative has been gaining popularity in recent years – clear aligners. 

What Are Clear Aligners?

Clear aligners are a discreet and comfortable option if you want to improve the alignment of your teeth. Unlike metal braces with unsightly brackets and wires, clear aligners are nearly invisible, making them attractive to those who want to straighten their teeth without drawing attention to the process.

Clear aligners like Invisalign, Clear Correct, Angel Aligners and Sparks are custom-made, transparent dental trays that snugly fit over your teeth. Clear aligners work progressively, applying gentle pressure to move your teeth into the desired position over time.

How Clear Aligners Work

The process behind clear aligner treatment typically involves the following steps.

  1. Consultation and treatment plan: Before using clear aligners, you’ll have a consultation with a dentist.  Prior to commencing clear aligner treatment, you will undergo a consultation with a dentist. During this session, they will evaluate your dental condition and devise a personalised treatment strategy utilising 3D imaging technology.
  2. Custom fabrication: Based on the treatment plan, a series of custom aligner trays are created. Each tray that is moulded to the shape of your teeth is designed to slightly shift them, gradually guiding your teeth into the desired alignment.
  3. Wearing the aligners: You’ll receive a set of aligners, each to be worn 20-22 hours for one week each. You wear them daily and at night, removing them only for eating, drinking, and oral hygiene.
  4. Switching aligners: You move on to the next set after the designated time. This process continues until your teeth have reached the desired alignment, as outlined in your treatment plan and advice of your dentist.
  5. Monitoring progress: You will have regular check-ups with your dentist to ensure your teeth are progressing as planned. If necessary, adjustments can be made to the treatment. For the busy professional, our dentists at Orchard Scott Dental can also do remote monitoring of your progress through the Dental Monitoring app. We track and communicate after every aligner to ensure the close care of your treatment.

Benefits of Clear Aligners

Aesthetic appeal

One of the most significant advantages of clear aligners is their discreet appearance. Traditional braces can be unsightly, whereas clear aligners are undetectable, allowing you to straighten your teeth without feeling self-conscious about your smile.

Removability and ease of cleaning

Clear aligners are easily removable, providing convenience during meals and allowing for thorough oral hygiene. Unlike traditional braces, there are no intricate wires and brackets to navigate around, making it simpler to maintain your regular dental care routine.

Comfort and reduced irritation

Clear aligners are made from smooth and durable plastic, reducing the risk of irritation to your cheeks and gums. Traditional braces, with their metal components, can sometimes cause discomfort and soreness, especially in the initial stages of treatment.

Less dietary restrictions

Unlike traditional braces that come with a list of prohibited foods that could damage the hardware, clear aligners can be removed during meals. Having the freedom to remove them when you need to means you can enjoy your foods without restrictions, allowing a more pleasant dental experience.


Clear aligners eliminate the urgency of braces emergencies. Even if an attachment detaches, you can continue until a dentist appointment is feasible, offering convenience for busy professionals or travellers.

Considerations Before Choosing Clear Aligners

Patient health profile

Clear aligners suit various dental issues. It’s advisable to consult a dentist to determine if clear aligners are the right choice based on your dental health profile.

Patient commitment

Successful clear aligner treatment requires patient commitment. Consistent wear is critical for the aligners to work effectively. You must be willing to wear the aligners daily for at least 20-22 hours and regularly replace the trays as advised.
