How long does clear aligner treatment take?

Treatment length depends on the complexity of the case. Mild corrections may take around 6 months, while many moderate cases take 12 to 18 months. Wearing the trays for the recommended 20 to 22 hours per day helps treatment stay on schedule.

Do clear aligners hurt?

Most patients describe clear aligners as pressure rather than pain. The pressure is usually most noticeable for the first couple of days after switching to a new tray and often fades within 48 hours.

Can I eat and drink with my aligners in?

Aligners should be removed before eating and before drinking anything other than plain water. After eating, patients should brush before putting the trays back in.

Are clear aligners covered by dental insurance?

Many plans with orthodontic coverage apply that benefit to clear aligner therapy, but coverage varies by plan. Markham Family Dental can verify benefits before treatment so patients understand their out-of-pocket cost.

What is the difference between clear aligners and Invisalign?

Invisalign is a brand name, while clear aligners are the treatment category. Several clear aligner systems work by gradually moving teeth with a series of custom trays.

Can clear aligners correct my bite, or only the appearance of my teeth?

Clear aligners can address both tooth appearance and certain bite concerns. Mild to moderate overbites, underbites, and crossbites may respond well, while more complex skeletal bite issues may require specialist care.

What happens if I stop wearing my retainer after treatment?

Teeth can shift back toward their original position without a retainer. Retainers help hold teeth in their corrected position after clear aligner treatment is complete.

Clear Aligner Therapy at Markham Family Dental Associates

Most people who want straighter teeth have been putting it off for one reason: they do not want to spend a year or two in metal braces. Clear aligner therapy removes that barrier. The trays are nearly invisible, come out for eating and brushing, and fit into the life of a working adult or a teenager without the friction that traditional orthodontics brings.

Our team treats both teens and adults with clear aligners and manages the full process here in Harlan, from the initial digital scan through your final retainer. This page covers what aligners can correct, who is a good candidate, and what treatment looks like from start to finish. We see patients from across Shelby County and no referral is needed.

Frequently Asked Questions

What Are Clear Aligners?

Clear aligners are a series of custom fabricated, removable plastic trays designed to move teeth gradually into the correct position. Each tray in the series is slightly different from the last, advancing the tooth movement by a small increment. When worn in sequence, the trays guide teeth from their current position to their planned final position over the course of treatment.

The trays are made from a smooth, clear material and fit flush against the teeth. They are not the same as the over the counter whitening trays or mail order aligner kits. Each set is custom made from a digital scan of your specific teeth and planned by our team to match your case.

What Clear Aligners Can Correct

Aligners are effective for a wider range of cases than most patients expect. The following are the conditions our team treats most commonly.

Crowded Teeth

When teeth overlap or are pushed out of position because there is not enough space in the arch. Mild to moderate crowding can usually be corrected without extractions.

Spacing and Gaps

Gaps between teeth, whether from a naturally wide arch, a missing tooth that has caused neighboring teeth to drift, or teeth that have shifted over time.

Overbite

When the upper front teeth extend too far over the lower front teeth. Many mild to moderate overbites respond well to aligner therapy.

Underbite

When the lower teeth sit in front of the upper teeth when biting down. Aligners can address mild underbites. More significant cases may require additional evaluation.

Crossbite

When some upper teeth sit inside the lower teeth rather than outside them. Aligner therapy is effective for crossbites when addressed early enough.

Clear Aligners vs. Traditional Braces

Both options move teeth effectively. The right choice depends on the complexity of your case and your priorities during treatment.

What the Treatment Process Looks Like

Consultation and Exam

Our team reviews your bite, tooth position, and gum health to confirm aligners are appropriate for your case. If there is active decay or gum disease, that is addressed first. If your case complexity is better suited to a specialist, we tell you at this stage.

Digital Scan and Treatment Simulation

We scan your teeth digitally. No trays of impression material. The scan generates a 3D model of your current teeth, and from that we build a simulation showing the full planned tooth movement from start to finish. You review and approve the projected result before any trays are made.

Tray Delivery and Fitting

Your custom trays arrive and you come in for a fitting. Our team seats the first tray, confirms the fit, and walks you through how to insert and remove the trays, how to clean them, and what to expect in the first few days.

Progress Appointments

Every six to eight weeks you come in briefly so our team can confirm your teeth are tracking correctly with the simulation. These visits are short. Between appointments you advance through your tray sets at home on the prescribed schedule.

Retainer

When the final tray is complete, we take a new scan and fabricate a retainer. The retainer holds your teeth in their corrected position. Without it, teeth will shift back over time. Our team discusses retainer options at the start of treatment so you know what the long-term commitment looks like before you begin.
