Invisalign® and 

Invisalign Teen®

What is Invisalign?


Invisalign® is a transparent, cutting-edge way to straighten your teeth and a popular alternative to metal braces. It consists of a series of clear, virtually invisible aligners that gradually and gently align your teeth.


Dr. Ferrell is a Premier provider of Invisalign®, a distinction given to only 5% of practices worldwide.


No brackets, wires or bands. This means that there will be minimal irritation and rubbing against the lips, cheeks and tongue as the Invisailgn® aligners consist of a smooth thermoplastic material, similar in look to teeth-whitening trays.


You can eat normally.

There are no dietary restrictions with Invisalign® as there are with braces. You remove your aligners prior to eating, and brush your teeth before you replace them. 


You can brush and floss now just as you always did.

It’s easy – you simply remove the aligners. There are no brackets or wires in the way of letting you brush and floss normally.


You can protect your teeth from grinding.

If you have a grinding or clenching habit of your teeth, the aligners can act as a thin nightguard to protect the teeth from wearing down.


You are always photo ready!

You'll never have to worry about picture day or that special occasion always picturing you with braces. Your Invisalign won't show in your photos!


You'll be more comfortable.

Invisalign technology eliminates poking wires and brackets. Not only does this reduce the possibility of additional appointments to repair broken brackets or protruding wires, but it's also much more comfortable!



Frequently Asked Questions



How does Invisalign® Work?

Dr. Ferrell approves a virtual set up of your teeth from their original position to their final straight position. A series of clear trays, called aligners, are custom-made for you to move your teeth in the pre-determined sequence. Each set of aligners is worn for one week. You will be seen in our office every 8-12 weeks throughout the process.


How often do I need to wear my aligners?

It is recommended that you wear your aligners for 20-22 hours per day and only remove them for eating, drinking, brushing and flossing.


Will wearing Invisalign® aligners affect my speech?

In some patients there may be a temporary and slight lisp for a day or two. However, as you get used to having aligners in your mouth, any lisp caused by the aligners should disappear with in a few days.


How much does Invisalign® cost?

In most cases, Invisalign® treatment is comparable to the cost of traditional braces. The cost depends on the complexity of the case and the length of time in treatment. The best way to know is to schedule a free initial consultation with our office.


Does insurance cover Invisalign®?

Because medical benefits differ from policy to policy, you should review your personal coverage plan and check with your insurance provider. In general, if a patient has orthodontic coverage, Invisalign should be covered to the same extent as conventional braces.


Does Invisalign really work?

Yes! Over 2 million patients with a wide variety of dental bites have been treated with Invisalign. Invisalign was developed with orthodontists and used in dental practices worldwide..
