What is Invisalign®?
Crooked teeth or a crowded bite can make you self-conscious every time you talk, eat, or pose for a photo. Invisalign® straightens your teeth using a series of clear, removable aligners custom-shaped to your mouth. Each set shifts your teeth a fraction of a millimeter, and you swap to a new set roughly every one to two weeks. Most adults and older teens finish treatment in 12 to 18 months.
We use Invisalign® at C. Patrick Gray, DDS. to treat gaps, crowding, overbites, underbites, and crossbites. The aligners are smooth, nearly invisible, and pop out when you eat or brush. Because nothing is bonded to your teeth, your regular cleanings stay simple the whole time. And once your teeth are aligned, you may find that a whitening treatment really makes the final result stand out.
Benefits of Invisalign®
Invisalign® aligners fit into your daily routine without asking you to put the rest of your life on pause.

Eat What You Want, Always
Pop your aligners out at mealtime and eat whatever sounds good. No brackets catch food, no wires can snap, and no food restrictions exist for the entire length of your treatment.

Treatment Nobody Notices
The clear trays sit nearly flush with your teeth and disappear at arm's length. Coworkers, classmates, and close friends usually won't notice you're in orthodontic treatment at all.

Fewer Office Visits Needed
We schedule checkups every six to eight weeks instead of monthly. Each visit is brief, and you handle the tray changes at home on the timeline we set at your last appointment.

Who Benefits from Invisalign®?
%20(1).png)
You've noticed your teeth shifting over the years, or maybe crowding that started in your teens has only gotten worse. Adults who skipped orthodontic treatment growing up are actually our most common Invisalign® patients in Flint, MI. Gaps, overbites, and crossbites that have gone untreated for decades all respond well to clear aligner therapy.
Teens and adults alike can wear Invisalign® aligners comfortably. If you grind your teeth at night, we may also recommend a night guard once treatment wraps up to protect your new alignment. And for patients considering veneers later, straightening first often means a better cosmetic result. Our team evaluates your bite, your bone health, and your goals before confirming you're a good fit.
Advanced Invisalign® Technology

Every Invisalign® case at C. Patrick Gray, DDS. starts with a digital scan instead of the thick putty trays that used to trigger gag reflexes. A handheld wand maps each tooth in about two minutes, and the resulting 3D model is accurate to roughly 50 microns. That scan feeds into ClinCheck software, which lets us show you a virtual preview of your projected tooth movement before a single aligner is made.
The aligners themselves are milled from SmartTrack material, a multilayer polymer that applies gentler, more consistent force than the rigid plastic used in earlier clear-aligner systems. SmartTrack grips your teeth more precisely, which means fewer mid-course corrections and shorter overall treatment for most patients in Flint, MI. Small tooth-colored attachments bonded to specific teeth give the aligners extra leverage for rotations or vertical movements that plastic alone could not handle.
What to Expect During Your Visit
Your first visit starts with digital scans of your teeth, which take just a few minutes and feel like nothing more than a small wand moving along your gums. We map out every shift your teeth need to make and show you a projected result on screen before you commit. If Invisalign® is a good fit, your custom aligners arrive within a couple of weeks.
You'll swap to a new set of aligners roughly every one to two weeks. Most people feel mild pressure for a day or two after switching, then it fades. We schedule check-ins about every six to eight weeks to track progress. Total treatment in Flint, MI typically runs 12 to 18 months, though simpler cases can wrap up sooner.
Before Appointment
Brush and floss right before your visit so we get the cleanest possible digital scans for your Invisalign® treatment plan.
Write down any questions about aligner wear time, switching schedules, or how Invisalign® fits into your daily routine.
Skip lipstick or heavy lip balm, since we may need to place small tooth-colored attachments that bond best to a dry surface.
After Appointment
Wear each set of aligners 20 to 22 hours a day, removing them only to eat, drink anything besides water, and brush.
Rinse your aligners with cool water each time you take them out. Hot water can warp the plastic and change the fit.
Switch to your next set of trays on the schedule we give you, even if the current set starts feeling loose early.
Frequently Asked Questions
We’ve answered the most frequently asked questions to help you feel informed, prepared, and confident before your appointment.
Can I play sports or musical instruments with Invisalign® aligners?
+Yes to both. The smooth plastic sits flush against your teeth, so there's nothing to cut your lips or cheeks during contact sports. Most wind and brass players adjust within a week or two of starting treatment.
How long do Invisalign® results last after treatment ends?
+Results are permanent as long as you wear your retainer consistently. Teeth naturally shift over time, so we recommend nightly retainer use for the first year, then at least a few nights a week after that.
Will Invisalign® affect the way I speak?
+You may notice a slight lisp for the first day or two. Your tongue adjusts quickly. Most patients speak normally within 48 hours, and the aligners are thin enough that other people rarely notice them at all.
Is Invisalign® a good option for adults over 50?
+Age alone isn't a limiting factor. Healthy gums and adequate bone support matter more than your birthday. We see patients in their 50s, 60s, and beyond get excellent results, especially for crowding that has gradually worsened.
How often do I need to come in for checkups during Invisalign® treatment?
+We typically schedule visits every six to eight weeks. Each appointment runs about 15 minutes. We check your progress, hand you your next sets of aligners, and make any adjustments to keep things on track.

C. Patrick Gray, DDS. was the first dentist office I have been to that actually took the time to listen.

Brought my two kids in for their first cleanings and the staff was wonderful with both of them. They explained each step so the kids knew what was coming and made the whole thing feel like a fun trip rather than a dental appointment. The office is clean, easy to find on Beecher Rd, and we always get in right on time.
