If our Invisalign quote looks higher than another office's, it's usually because ours is the whole price. Tanglewood charges one flat fee that covers your aligners, your retainer, any TADs Dr. Lawnin decides you need, and every step in between. Many offices quote the aligners alone and bill the rest as you go.

Your fee is set at your consultation, and that number doesn't change partway through treatment. Here's what it covers, and how to compare it fairly with other quotes.

Where the extra fees usually show up

A lower Invisalign quote often covers the aligners and little else. The rest arrives later, once you're already committed to treatment. The most common add-ons are:

• Retainers. Every aligner patient needs a retainer at the end to hold the result. At some offices that's a separate charge of around $700, billed after you've already paid for your aligners.
• TADs (temporary anchorage devices). These small, temporary anchors give certain tooth movements a fixed point to push against. When a case needs them, they're often billed on top of the aligner fee.
• Extra aligners. If your teeth need more fine-tuning than the first set planned for, additional aligners can come with their own fee.

None of these are unusual. They're a normal part of many aligner cases. The difference is whether they're priced into the quote you see at the start.

What our flat fee includes

At Tanglewood, everything Dr. Lawnin decides your case needs is in the one price:

• Your full series of Invisalign aligners, plus any refinement aligners needed to finish your case
• Your retainer at the end of treatment
• TADs, if Dr. Lawnin uses them for your case

If Dr. Lawnin adds a TAD halfway through, your teeth need a round of refinements, or you need a retainer at the finish, there's no second bill. The number you agree to at the start is the number you pay.

Why we chose a flat fee

Two reasons. First, you can plan for it. You know the full cost before you start, so there's nothing to budget around later.

Second, it keeps the clinical decisions clean. When a TAD or a round of refinements is already included, Dr. Lawnin can recommend it purely because your case calls for it. You never have to weigh a better result against another invoice halfway through treatment.

That's why our quote can look higher at first glance. It already contains the costs that show up later elsewhere.

How to compare Invisalign quotes fairly

To compare two quotes on equal terms, ask every office the same questions:

1. Is the retainer included, and if not, what does it cost?
2. If my case needs TADs, are they included?
3. If I need extra aligners to finish, is there an additional charge?
4. Are check-in visits and scans part of the price?
5. Is this the total I'll pay, start to finish?

Add the answers to the base quote. That total is the number to compare with ours.

Frequently asked questions

How much does Invisalign cost at Tanglewood?

We charge one flat fee, set at your consultation. It includes your aligners, any refinements, your retainer and any TADs Dr. Lawnin uses, so there are no add-on charges later.

Why is your Invisalign price higher than other offices?

Because it includes costs that many offices bill separately, like the retainer and TADs. Once you add those to a lower quote, the totals are often much closer.

Is a retainer included with Invisalign?

At Tanglewood, yes. At some offices it's a separate charge after treatment, so ask before you compare.

What is a TAD in orthodontics?

A TAD, or temporary anchorage device, is a small temporary anchor that gives certain tooth movements a fixed point to push against. Not every case needs one. When yours does, it's included in our fee.
