Invisalign is the obvious alternative to metal braces. Invisalign utilizes a series of clear, removable aligners that are custom-made to fit each individual. The practically transparent aligners steadily straighten your teeth without the unappealing look of traditional metal braces. Due to the removable nature of the device, brushing your teeth and eating becomes less of a nuisance as with the metal braces.

How Invisalign can develop the strength of your mouth.

Teeth that are packed together or too widely spaced can create unhealthy conditions, including swollen gums, redness and pocketing, all of which are signs of periodontal disease. As Invisalign unnoticeably straightens your teeth, it will also make sure your teeth is aligned properly.

Healthier Gums

Thorough research has indicated that gum health may improve with the use of Invisalign during orthodontic treatment. Properly aligned teeth can help gums “fit” tighter around each tooth, which may lead to better periodontal health. As opposed to braces, with Invisalign, you can brush and floss normally, which can help to avoid tooth decay and gum disease.

Easier to clean

Unlike conventional braces, Invisalign has no metal bands or wires to ensnare with food or plaque. Sustaining a good oral hygiene program will inevitably reduce chances of plaque buildup, tooth decay and gum disease.

Improved Chewing and Speech

For most individuals, incorrectly situated teeth and jaws can exacerbate speech impairment and chewing problems. Adjusting your bite by straightening your teeth through Invisalign can help improve both.

Lower Risk of Trauma
and Abnormal Wear

Teeth that are properly aligned will not cause any burden on the supporting bone and jaw joints

Different Types of Invisalign

1. Invisalign EXPRESS

Invisalign Express was developed as a solution for people who require minor tooth correction, whether adult or teenager. It can treat that slight overcrowding or annoying crooked front tooth that has bothered you for some time. People who had orthodontic treatment in the past may find that their teeth have shifted over time, leaving them once again feeling self-conscious about their crooked smile. Invisalign Express can help by providing a series of clear, nearly invisible, removable aligners that fit easily and discreetly into your lifestyle.

2. Invisalign Lite

Invisalign Lite is available for slight correction of teeth that needs few movements to rectify the. Normally, Invisalign Lite requires for 8 to 14 aligners and the treatment is estimated to be complete by 6 months to 1 year.

3. Invisalign Teen

Let’s face it. With school, sports and hanging out with friends, getting metal braces is not at the
top of your list of favorite things to do. Guess what? With Invisalign Teen®, you can straighten your teeth without having to deal with metal wires and brackets. That means you can still do all the things that make these the best times of your life.

Teens are smiling about Invisalign Teen because:

  • They look great — in your yearbook, on Facebook, or in family photos, it will be hard for people to tell you’re wearing the aligners. Even in person, they’re virtually impossible to see!
  • They’re cool — why be insecure about ugly metal braces at a party, a prom, or an interview? Now you can look great with Invisalign Teen.
  • They’re easy to maintain — when it’s time to eat, brush, or floss, simply remove your aligners. And, unlike metal braces, you can remove the aligners and eat whatever you want pizza, apples, popcorn . it’s totally up to you!
  • They’re more comfortable — Invisalign Teen aligners are made of lightweight plastic and custom-fit snugly around your teeth. And you won’t have to worry about the irritation and inconvenience of metal braces.
  • They’re simple to remove — the aligners are easy to pop out of your mouth and put them right back in later. When it comes to sports, meals, parties, playing musical instruments—you name it—Invisalign Teen is easily removable. So it’s easy to go for it!

Parents are smiling about Invisalign Teen because:

  • You want what’s best for your child. Invisalign Teen can help build your teen’s confidence—a beautiful smile may enhance their chances to succeed during social, educational, and career events.
  • Because your teen doesn’t have to be embarrassed by wearing visible metal braces, they may be able to more fully concentrate on school, social events, dates, sports, and musical interests, and any of the other many activities a teen concentrates on.
  • Since the aligners are removable, it’s easier for teens to brush, floss, and practice excellent dental hygiene—helping to avoid the tooth decay that’s sometimes associated with metal braces.
  • Perhaps best of all, Invisalign Teen aligners work. They use the same Invisalign technology that doctors worldwide have used to treat more than three quarters of a million patients who have wanted better smiles. Shouldn’t your teen’s smile be next?

4. Invisalign Comprehensive

Invisalign Comprehensive is for patients diagnosed with a more complicated case, such as very crowded teeth. For majority of these cases, it would take up to an average of 18 months to complete the treatment. However, the exact treatment time can increase or decrease depending on the complexity of each case. These cases would take up more than 14 pairs of Invisalign aligners.

How Invisalign works?

In the past the main drawback of conventional braces used to correct, straighten, rotate, and align crooked teeth is that you could see them. Fortunately, Invisalign produces the same results – and YOU don’t look unattractive during the process. The question now is HOW?

The Invisalign process begins with a series of snap-on, custom fit, removable mouth trays, or aligners. These Invisalign aligners apply a controlled amount of pressure to your teeth, forcing them to shift. The process continues with a computer-generated image of what your teeth will look like at each stage of treatment from beginning to end. Each stage corresponds to the movement built into a set of aligners.

Additionally, each aligner is designed to pressure specific teeth to move into place. Like brackets and arch wires, Invisalign Aligners move teeth through the appropriate placement of controlled force on the teeth. The key difference is that Invisalign not only controls forces, but also controls the timing of the force application. At each stage, only certain teeth are able to move and these movements will be determined

by the orthodontic treatment plan for that particular stage. Accordingly, it results in an efficient force delivery system.

Ultimately, every fortnight you will switch to a new Invisalign tray. The clear plastic composition of the Invisalign trays is what makes it invisible when they are on your teeth.

Doesn’t it sound like Invisalign is the right option to straighten your smile? If yes, contact Dentajoy today and set up an appointment with one of our orthodontists to discuss a possible Invisalign treatment plan for you.

Getting Started

It is as simple as making up your mind to go to the movies. This time all you have to do is decide to improve your smile – the rest is upon us.


Make an appointment with Dentajoy. During the initial visit, our compassionate staff will help you decide on the course of your treatment. Dentajoy will then take impressions of your teeth and immediately start to make your aligners by Itero intraoral scanner


Dentajoy uses advanced 3-D computer imaging technology to convert your bite impressions into a custom-molded series of clear and removable aligners. There could be as many as 48 in the series or as little as 12, depending on your individual treatment plan.


During your next visit to us, you will receive your first set of aligners. Dentajoy will provide you a few additional sets for you to wear before your next visit.


You should wear each set of aligners daily for a fortnight, removing them only to eat, drink, brush, and floss. Total treatment time averages 9-15 months, but will vary from case to case. You’ll visit us every 6 weeks to make sure that your treatment is progressing as designed.


Congratulations! The Invisalign process is now complete. However, you will need to wear a retainer for some time to keep your teeth in their new and improved position. Be sure to practice good dental habits and have regular dental checkups to keep your new smile in the best condition possible.
