The short answer: Invisalign uses a series of custom, clear plastic trays, each one slightly different from the last, that gradually apply gentle pressure to move your teeth into a planned final position. You wear each tray about 20-22 hours a day and switch to the next one on a schedule Dr. Villa sets, typically every one to two weeks. Dr. Richard Villa has fit Invisalign in Glen Allen since 1998, among the first orthodontists in the Richmond area certified in the system.

It Starts With a Digital Plan, Not a Guess
Before any aligners are made, Dr. Villa examines your teeth and bite in person and takes a digital scan. That scan becomes the basis for a full treatment plan mapping out exactly how each tooth needs to move, in what order, and how many aligner stages it will take to get there — the entire course of treatment is planned before you ever wear the first tray.
Each Tray Does a Small Amount of Work
Every aligner in the series is shaped very slightly differently from the one before it — just enough to apply gentle, continuous pressure that nudges specific teeth in a specific direction. No single tray moves a tooth very far. It’s the accumulation of many small, sequential shifts, each held in place long enough for the tooth to respond, that adds up to the full correction by the final tray.
Wear Time Is What Makes It Work
Invisalign only moves teeth while the aligner is actually in your mouth. The 20-22 hour daily wear target exists because teeth need sustained pressure to move; take the trays out too often and progress slows or stalls. Aligners come out for eating, drinking anything but water, and brushing and flossing, then go back in.
Attachments and Elastics Do the Fine-Tuning
Some teeth need more than a tray pressing on their surface to move correctly, especially rotations or teeth that need to move vertically. For those cases, Dr. Villa may bond small, tooth-colored attachments to specific teeth that give the aligner something to grip, or use small elastics to help correct a bite issue — both are common, not a sign that something has gone wrong with your plan.
Check-Ins Keep the Plan on Track
You’ll return periodically so Dr. Villa can confirm your teeth are tracking with the plan and hand you the next set of trays. If a tooth isn’t moving quite as predicted, the plan can be adjusted with a refinement — a new short series of aligners — before finishing treatment.
Retention Locks In the Result
Once your teeth reach their final planned position, a retainer is what keeps them there while the bone and ligaments around each tooth stabilize. Skipping retainer wear is the most common reason a finished Invisalign result doesn’t last.
Frequently Asked Questions
How many hours a day do I actually need to wear Invisalign?
About 20 to 22 hours a day, removing the trays only to eat, drink anything besides water, and brush and floss. Less wear time generally means treatment takes longer than planned.
Does Invisalign work the same way for teens as adults?
The mechanics are the same, but a teen’s plan accounts for growth and any remaining baby teeth. Dr. Villa evaluates each case individually rather than applying one template to every age.
What if a tooth isn’t moving the way the plan predicted?
Dr. Villa checks progress at scheduled visits and can order a refinement — a new short series of aligners — to correct course before finishing treatment.
Can Invisalign fix a bite problem, or just crowding and spacing?
Both, depending on the case. Attachments and elastics allow Invisalign to address certain bite issues in addition to straightening; more complex bite or jaw problems may call for surgical orthodontics or braces instead.
