Invisalign is a popular alternative to wire braces, and it uses a system of incremental aligners to adjust
the teeth. This process requires that each aligner is worn for at least 20 hours a day for two weeks at a
time before moving on to the next aligner in the series. There are a variety of pros and cons associated
with this system, and your dentist can help you determine if Invisalign is right for you.
The Benefits of Invisalign 
There are several advantages of Invisalign that attract dental patients to choose this method of
straightening their teeth:
• Appearance. Invisalign consists of clear plastic aligners rather than a bulky metal appliance, so
many adults who want to straighten their teeth choose this option. The aesthetic benefits of
Invisalign are one of the greatest reasons that dental patients choose this method.
• Straighter Teeth. The Invisalign system has been proven effective at straightening mild to
moderate cases of teeth spacing, crowding, underbite, overbite, and crossbite problems.
• Dental Hygiene. With the Invisalign system, you will remove your braces in order to brush your
teeth. This allows you to ensure that your teeth are cleaned properly, which may be difficult
with other orthodontic options.
• Customized. The Invisalign system is customized for your unique teeth at the Invisalign lab. This
can result in a comfortable teeth straightening experience.
• Lifestyle. Since you can remove your Invisalign braces at will, the experience will result in
minimal lifestyle changes. You can continue to eat what you want without fear of damaging
your braces, and you can continue to play your favorite contact sport or instrument without
interference from metal brackets and wires.
The Disadvantages of Invisalign
Like any orthodontic treatment option, there are some shortcomings associated with the Invisalign
system:
• Speech Problems. Some patients report difficulty with their speech within the first few weeks of
using Invisalign. A lisp is the most common issue, but it should go away after you have had time
to adjust to your braces.
• Inconvenience. You’ll need to remove your Invisalign aligners every time that you eat or drink,
which may not always be convenient, especially if you are out in public. This could also lead to
misplacing your aligners, which can be expensive to replace and may put your treatment off
schedule.
• Treatment Delay. If you decide that Invisalign is the treatment that you want to pursue to
straighten your teeth, your orthodontist will need to send your molds, x-rays, and treatment
plan to Invisalign. The Invisalign lab, then creates a simulation to send to your orthodontist.
If your orthodontist approves the simulation, the aligners are created and sent to your dental
office. This can take up to six weeks.
If you are interested in Invisalign, contact your dentist to find out if you are a candidate to straighten
your teeth with this system.
