Here’s everything you need to know about invisalign treatment in Singapore

What is Invisalign Treatment?

Invisalign treatment is a modern approach to straightening teeth, using a custom-made series of transparent, medical-grade plastic dental braces created for you and only you. The aligners are virtually invisible and fit comfortably over your teeth. Each aligner moves your teeth slightly, moving them horizontally and vertically and even rotating them when required. Changing the next set of aligners make your teeth move into position. It is ideal for image-conscious teens and adults who want straighter teeth but will not consider metal braces. This is because they are transparent and therefore unnoticeable. Virtually no one will notice that you are straightening your teeth. They are strong and comfortable to wear because of their flexibility, and you can easily maintain good oral hygiene while wearing Invisalign clear aligners because they are removable.

The following dental issues can be treated with Invisalign:


This is when there isn’t enough room within the jaw for all the teeth to fit normally. Overly crowded teeth can cause dental decay, increase the chances of gum disease and can inhibit the normal function of teeth. It can be treated with Invisalign clear aligners over a period of six to eighteen months, or longer depending on individual’s dental condition.


This is a situation when the upper teeth overlaps the lower teeth too much. Not only is this a cosmetic issue, but it can lead to health problems later in life. This dental issue can be corrected using Invisalign clear aligners.


It is when the lower teeth protrude past the front teeth. It’s usually caused by undergrowth of the upper jaw, overgrowth of the lower jaw, or both. It can lead to tooth wear and also causes painful jaw and joint pain. This disorder can also be corrected using Invisalign clear aligners.

Open Bite

This is when the teeth is abnormally spaced and very far apart, while this might just seem unattractive, spacing issues in teeth can also cause some periodontal diseases. It can also be corrected with Invisalign clear aligners.


The patient has to meet with several experienced dentists to find the one he is most comfortable with. During consultation, the dentist will discuss the patients’ needs and evaluate whether Invisalign treatment is right for him/her. After that the dentist will use a scanner to create fast, precise 3D digital images of the patient’s teeth. In some cases, dentists take physical impression.

Then the dentist will map out a treatment plan that includes the movement of teeth and how long the treatment will be.

Custom-made clear aligners will then be made & delivered to the clinic in about 4 weeks time from the date of treatment plan confirmation. Patients are advised to wear their Invisalign clear aligners for 20 to 22 hours a day for the best results, removing them only to eat and to brush and floss. Through the progression of each aligner that patients wear. Patients’ teeth will gently and gradually shift into place. At every stage, patients will be able to see notice some progress.

Living with Invisalign clear aligners has a minimal impact on the patient’s day-to-day life. The patient can simply brush and rinse the Invisalign in lukewarm water. Patients can easily remove the clear aligner during meals. This means they can continue to eat all the foods they love without any restrictions or worrying about food getting stuck in their wires and brackets. They can go about their daily activities without the worry of sharp brackets cutting their mouth and causing pain.
