When most people hear what Invisalign promises, they are somethings slow to believe that it can actually deliver. Straighter teeth without pain or any metal bracket or wires?

Because Invisalign is relatively new, most people grew up either wearing those metal braces or seeing their friend wear the metal braces. Because of how much time and effort is put into the entire braces process, it can be difficult to believe that a few plastic trays can straighten teeth just as effectively. When it comes to answering the question, “Does Invisalign work?” there are a few factors that have to be taken into consideration.

Does Invisalign Work?

One of the most common stipulations about Invisalign is that the aligners only work for very minor issues. The truth is, however, that Invisalign can correct most of the minor, moderate, and even some of the severe issues that a set of metal braces can correct. Most of the more severe orthodontic problems aren’t actually solved by the braces themselves, but by other applications like spacers, expanders, or the dreaded headgear. Crowding, gaps, and even turned teeth can be corrected with Invisalign, often just as well as these issues can be corrected with brackets and wire.

There are now far more issues that can be addressed with Invisalign than when the aligners were first introduced. In the beginning, the aligners really were only able to treat a few problems, while most serious problems required more traditional treatments. Now, with attachments, movements, buttons, and even elastics, all of which can be applied to the aligner, orthodontists have many more options.

Overall, Invisalign clear braces are an effective solution for a myriad of teeth alignment problems, everything from a few crooked or protruding teeth to more serious problems like malocclusion, overbite or underbite.

The most common problems Invisalign braces are used to treat include gapped teeth, an overbite which occurs when the upper teeth protrude out over the lower teeth, underbite which is when the lower teeth protrude past the upper teeth and an open bite where the teeth are not aligned properly for a proper bite. Other treatable issues are overcrowding of teeth and a crossbite which can happen if both the upper and lower jaws are not aligned properly. All of these conditions can lead to tooth decay and loss and gum disease as well as jaw problems if not corrected.

How Does Invisalign Work?

Unlike with traditional braces that use a wire to push or pull teeth into the most optimal alignment, Invisalign uses a series of plastic aligners to push the teeth into a better alignment.

The Invisalign 3D technology allows your orthodontist to create a step by step plan for your treatment so you will know what to expect every step of the way. The orthodontist will take x-rays and impressions of your teeth to create a 3-D image of your teeth and then uses this to map the exact movement of teeth needed to straighten them out.

Once the plan is in place, your first set of aligners will be custom fit to your mouth. And then you will receive a new set every couple of weeks until the end of your treatment.

Another stipulation many orthodontists make while advising their patients about the difference between Invisalign and a more traditional treatment is that Invisalign usually takes longer than metal braces. Why? Because plastic just isn’t as strong as metal and the aligner system naturally progresses at a slower rate than metal braces.

This does actually have a number of positive benefits, however, including the fact that patients who choose Invisalign experience less discomfort than patients that choose braces. If the teeth are being pushed and pulled less, they will be less sore.

The aligners system itself provides a number of benefits, including the ability to take them out to brush teeth, eat, and to clean the trays themselves. They are also virtually invisible (hence the name), which can eliminate the self-consciousness a person wearing metal braces might feel about smiling or speaking. This is especially true of Invisalign teen systems, as teenagers often struggle with the hassle of wearing braces. Removing your braces just isn’t possible with traditional treatments, and the braces themselves can make it more difficult for the wearer to clean his teeth. Of course, using the right technique and even the special brushes provided to you by your dentist, can make keeping your teeth clean while wearing braces fairly easy.

Why Would Invisalign Fail?

One of the major downfalls of Invisalign is that it requires a very high level of patient compliance. Because a patient can take the trays out whenever they want, some patients forget to wear them or choose not to wear them for hours every day. Invisalign is most effective when it is worn for more than twenty-three hours every day. Patients that wear their aligners for twenty-two or fewer hours every day will not only see slower results, they may see no results at all. Enough time out of the trays during the day can undo any of the moving or shifting that the teeth have done while the aligners are worn.

Even people who have graduated from metal braces to plastic retainers will tell you that sometimes their retainers feel tight and uncomfortable when they put them on at the end of the day. That is because in less than twenty-four hours, the teeth have begun to shift back to their former positions, even years after the metal braces have been removed and the patient has been faithful about wearing his retainer.

If a person does not wear the Invisalign aligners for the vast majority of their day, they will begin to see slower and slower, and then no results at all. Aligners should only be taken out to eat and to brush and floss the teeth. Patients who have a hard time complying with this rule might be better off choosing metal braces, which cannot be taken out—though those patients usually do also have trouble complying with dietary restrictions and a cleaning routine. A better plan of action is to become the sort of patient who does comply with the rules given to you by your orthodontist.

In addition, most orthodontic patients, being treated with Invisalign and other types of braces, have to wear a retainer after your treatment is done. It can definitely be frustrating, but it is a very necessary extra step. Even after a full treatment with Invisalign, your teeth will start to shift a little again after the aligners are taken off. When you wear retainer, your teeth are held in their new positions for longer which will ultimately give you better results.

Some orthodontic patients need to just wear one retainer on the bottom or on the top, but some patients might need both. Typically at first, you will wear the retainer all day long and then you will most likely only have to wear it at night to sleep. Keep in mind that each individual treatment plan is different.

Types of Retainers

Retainers generally come in two types, removable and fixed. The removable kind are usually worn for about a year, while the fixed retainer may be worn for several years. Fixed retainers are adhered to the backs of your teeth using cement.

Retainers are typically made of:

  • Acrylic – These are the most common type of retainers. They are made of bendable wire and acrylic and are adjustable. They also come in different colors and styles
  • Clear – These are made of molded clear plastic that fits over your teeth. Because these are less noticeable they are a popular choice, especially for adults.

Invisalign vs. Metal Braces: Which Works Better?

If your orthodontist believes that either Invisalign or metal braces will solve your alignment issues, picking a system will probably come down to how willing you are to comply with the rules of Invisalign. The treatments are close in price, and while braces may solve some problems faster than Invisalign will, the promise of less discomfort and the ability to remove the trays for cleaning and eating is very attractive to most patients and usually makes up for any slight discrepancies there may be in price.

    What I don’t get is—-if your teeth can “shift” back out of alignment, what happens when you stop wearng the invisalign plastic aligners? Once you’ve committed to wearing invisalign, do you have to wear it for the rest of your life?

    My dentist’s receptionist joked about the “invisalign diet,” saying that when patients start wearing invisalign aligners, they can’t snack as much, due to having to keep the trays in their mouths as much as possible and then the amount of work it takes to brush and floss your teeth and clean the trays EVERY SINGLE TIME you eat anything.

    I just cannot imagine having to wear these plastic things 22 hours a day for years and years. UGH.

      You wear it every day at first but then u can put them on only at night. Another option is to put a metal brace behind your teeth after braces.

      That’s the thing my Orthodontist never told me. You have to wear retainers for the rest of your life.

    You have to wear retainers every day for the rest of your life after braces, too, if you don’t want them to shift at all. Otherwise, teeth move over time. You should wear them for at least a year or two, or they will go back to where they were used to being. After that, if you stop wearing them, they will shift some, but not as much. This is not a braces verses retainers issue. I let my bottom teeth shift back on purpose after I got braces because my orthodontist bowed them out to make them all fit on my small jaw, and I didn’t like it did to my bite. They went back and are a bit crowded, but no one ever notices and I get compliments all the time on my teeth. I wore my top retainer for the recommended time and then stopped, and they kept their shape just fine, but over decades I’ve developed an overbite I never had before. So, you know, you don’t have to wear them forever, but they will move around some if you don’t. Depends on how long you wear them for after treatment so that they get used to being in their new locations, and how fussy you are about wanting your teeth just perfect. It’s not like you have to wear them all day every day. You just put them in at night after treatment. If you’re wearing the plastic retainers that cover the whole teeth, that’s good to wear at night anyway, to keep you from grinding your teeth while you sleep (also helps with TMJ issues). The truth is, the retainers are easy to clean if you do it every day, anyway. You just scrub them with a little soap on your toothbrush when you brush your teeth. No big deal.

  3. I just got my Invisalign today. I’m quite scared mainly about it not working and dieting. I’m a pretty heavy snacker, I love eating snacks, so i feel now that I have my Invisalign i’ll drop a lot of weight, and i’m not over my weight so I don’t wanna end up being under. I’m super paranoid it won’t work so I know I’d for sure wear it for 23 hours just scared that still won’t do anything and my teeth will wind up how they are now.
