WHY INVISALIGN
The Smarter Way to Straighten Your Smile
Invisalign clear aligners fit seamlessly into your life — whether you’re at work, at school, or out with friends. No brackets. No wires. No food restrictions. Compared to traditional metal braces, Invisalign is virtually invisible, more comfortable day-to-day, and lets you eat, brush, and floss exactly the way you always have — without wires to work around.
Virtually Invisible
Clear aligners are so discreet, most people won't even notice you're straightening your teeth. Perfect for professionals, students, and everyone in between.
Comfortable to Wear
Made from smooth BPA-free plastic with no sharp wires or brackets to irritate your gums, lips, or cheeks. Most patients adjust within the first few days.
Removable for Meals
Take out your aligners to eat, drink, brush, and floss. No diet restrictions. No complicated cleaning routines. Life goes on as normal.
Better Oral Hygiene
Unlike braces, removable aligners let you brush and floss normally — reducing the risk of cavities and gum disease throughout treatment.
See Results Before You Start
Our team uses advanced 3D imaging to map your entire treatment and show you a digital preview of your finished smile — before you commit to a single aligner.
Fewer Office Visits
Check-ins are typically every 6–8 weeks — far fewer than traditional braces. Spend less time in the chair and more time enjoying your life.
What Conditions Does Invisalign Treat?
Invisalign isn’t just for minor cosmetic gaps — it’s an effective treatment for a wide range of bite and alignment issues, including:
- Crowded teeth
- Gaps and spacing between teeth
- Overbite
- Underbite
- Crossbite
- Open bite
- Mild to moderate jaw misalignment
At your consultation, Dr. Marc or Dr. Molly Valli will evaluate your specific bite and teeth and give you an honest recommendation — including whether Invisalign is the right fit, or whether another treatment would serve you better.

COST & INSURANCE
Investing in Your Best Smile
We believe cost shouldn’t stand between you and the smile you deserve. Here’s what to know about Invisalign pricing and coverage.
Invisalign Treatment Cost $5,600 Flat Rate
This price covers your full Invisalign treatment and your retainers at the end of treatment — no extra cost for retainers later. New patients may have additional costs if X-rays, an exam, or other dental treatment (such as a cleaning or addressing a cavity) are needed before starting Invisalign. We’ll review all of this with you at your consultation, so you know exactly what to expect before committing.
Invisalign Consultation $99
Invisalign Consultation $99 for new patients without insurance, which includes your consultation and X-rays. Many dental insurance plans cover Invisalign the same way they cover traditional braces — often $1,000–$2,000 in orthodontic benefits. We’ll verify your coverage before your consultation and handle all the paperwork. We also offer flexible in-house financing plans.
FAQS
Your Invisalign Questions, Answered
We hear these questions every day. Here are honest, straightforward answers to help you decide with confidence.
Am I a good candidate for Invisalign?
Invisalign works well for most adults and teens with mild to moderate crowding, spacing issues, overbites, underbites, and crossbites. It’s not limited to cosmetic cases — many bite problems respond very well to clear aligner treatment. The best way to find out is a consultation with Dr. Marc or Dr. Molly Valli — just $99 for new patients without insurance, which includes your X-rays — who will assess your smile and make an honest recommendation.
How much does Invisalign cost in Groton, MA?
Invisalign treatment at Smiles of Groton is a flat $5,600, which includes your full treatment and your retainers — no surprise cost for retainers down the road. New patients may have additional costs if X-rays, an exam, or other treatment are needed before starting Invisalign; we’ll let you know exactly what to expect at your consultation. Many dental insurance plans cover Invisalign similarly to traditional braces, often providing $1,000–$2,000 in orthodontic benefits. For new patients without insurance, your initial consultation and X-rays are just $99. We also offer flexible financing options to fit your budget.
What should I expect at my first visit?
Your first visit starts with a conversation. Dr. Marc or Dr. Molly Valli will examine your teeth and bite, take any necessary X-rays, and talk through your goals. If Invisalign is a good fit, we’ll capture a 3D digital scan of your mouth using our iTero scanner, which lets you preview your future smile before committing to treatment. This initial visit is $99 for new patients without insurance and covers your consultation and X-rays.
How long does Invisalign treatment take?
Most adult Invisalign cases take between 12 and 18 months. Minor cosmetic corrections can be completed in as few as 6 months, while more complex bite issues may take closer to 24 months. Your timeline depends on the amount of tooth movement needed and how consistently you wear your aligners (the recommended 20–22 hours per day). Dr. Valli will give you a realistic estimate at your consultation based on a 3D scan of your specific teeth.
Does Invisalign hurt?
Most patients experience mild pressure or slight discomfort for the first day or two after switching to a new set of aligners — this is completely normal and a sign the aligners are working. Unlike traditional braces, there are no sharp wires or brackets to irritate your mouth. The discomfort is generally much milder than braces and typically goes away on its own within 48 hours. Over-the-counter pain relievers like ibuprofen can help if needed.
Can I eat and drink normally with Invisalign?
Yes — this is one of the biggest advantages of Invisalign over traditional braces. You simply remove your aligners before eating or drinking anything other than water, enjoy your meal as normal, then brush your teeth and put your aligners back in. There are no food restrictions. Sticky candy, hard foods, coffee, wine — all fine, as long as your aligners are out. This also means cleaning your teeth is as easy as it always has been.
How often do I need to come in for appointments?
Invisalign requires far fewer office visits than traditional braces. After your initial consultation and aligner fitting, most patients check in every 6–8 weeks for a brief progress review. There are no monthly wire adjustments. Many patients receive multiple sets of aligners at once and simply switch to the next set at home on schedule. This is ideal for busy adults and teens who can’t easily leave work or school for frequent appointments.
How do I keep my aligners clean?
Cleaning your aligners is simple. Rinse them every time you take them out, and brush them gently with a soft toothbrush and mild, clear (non-colored) soap or Invisalign cleaning crystals. Avoid using toothpaste, which can scratch the plastic and make aligners look cloudy. Never soak them in mouthwash or hot water — this can warp the aligner material. Since you’ll be swapping to a new set every 1–2 weeks, keeping them clean is straightforward.
Is Invisalign effective for teens?
Absolutely. Invisalign offers a dedicated Teen program with special features including compliance indicators (small blue dots that fade as aligners are worn, making it easy to track daily wear) and additional replacement aligners in case one is lost. For many teens, the discretion and confidence of not wearing metal braces is a huge benefit — especially during school photos, sports, and social events. Dr. Valli will assess whether Invisalign Teen is right for your child.
What happens after Invisalign? Do I need a retainer?
Yes — retainers are an important final step for any orthodontic treatment, Invisalign included. After you complete your last set of aligners, Dr. Valli will fit you with a custom retainer to keep your teeth in their new positions. Your retainer is included in your $5,600 treatment cost, so there’s nothing extra to pay for at the end. Without a retainer, teeth naturally tend to shift back over time. Many patients wear their retainer only at night after the first year. We’ll give you detailed instructions tailored to your case.
Can I get Invisalign if I have dental work like crowns or veneers?
In many cases, yes. Crowns, veneers, and bridges don’t automatically disqualify you from Invisalign. Some patients need minor restorative work completed before beginning aligner treatment, while others can proceed with existing dental work in place. Cavities and active gum disease should be addressed first, which may mean some additional treatment beyond the $5,600 Invisalign cost — something we’ll always discuss with you upfront. Dr. Marc and Dr. Molly Valli will review your full dental history and create a comprehensive plan that addresses all your needs correctly.
How is Invisalign different from cheaper clear aligner brands?
Mail-order aligner brands (like Smile Direct Club, which has since gone out of business) operate without in-person exams or professional supervision — a significant concern for long-term oral health. Invisalign treatment at Smiles of Groton includes thorough clinical evaluation, in-person 3D scanning, and regular check-ins with Dr. Valli to monitor your progress and make adjustments. The SmartTrack® material used in Invisalign is clinically proven to move teeth more predictably than generic alternatives. When it comes to your smile and bite, supervised care matters.
