Dental Website Accessibility (ADA): A Plain-English Checklist

Your dental website should work for patients who are blind, have low vision, are deaf or hard of hearing, or can't use a mouse. That's the practical goal behind dental website ADA compliance, and it's also the best protection against the demand letters that accessibility lawyers send to small businesses, including dental offices.

The short version: build your site to meet WCAG 2.1 Level AA (or the newer 2.2), test it with real tools and a keyboard, and fix problems in the site itself rather than relying on a plug-in widget. The checklist below breaks that down into tasks your web provider can act on.

This article is general information, not legal advice. Accessibility law is still evolving. If you receive a demand letter or want a formal opinion on your obligations, talk to an attorney who handles ADA matters.

What dental website ADA compliance means legally

The Americans with Disabilities Act requires businesses open to the public, including dental practices, to provide equal access to people with disabilities. Title III of the ADA was written before websites existed, and it doesn't spell out a technical web standard for private businesses.

Here's where things stand in general terms:

• Courts have often treated business websites as covered, particularly when the site is connected to a physical location like your office. Courts in different parts of the country haven't always agreed on the details.
• The Department of Justice has said websites should be accessible and has pointed to the Web Content Accessibility Guidelines (WCAG) as helpful guidance. Its formal rule setting WCAG 2.1 AA as the standard applies to state and local governments under Title II, not to private practices.
• WCAG 2.1 AA is the benchmark most people use in practice, including in many settlements and audits. WCAG 2.2 adds a few more criteria and is a sensible target for a new build.
• Some states have their own laws that can add obligations or remedies.

So there's no single federal checklist with your practice's name on it. But building to WCAG AA is the widely accepted way to show you've made a real effort.

Why this matters beyond lawsuits

Accessibility fixes tend to make the site better for everyone. Captions help the patient watching your video on a bus with the sound off. Clear contrast helps the older patient reading on a phone in bright sunlight. Labeled form fields help anyone filling out an appointment request one-handed.

Your patient base includes people with low vision, hearing loss, arthritis and tremors. Many of them are exactly the patients who need regular care and who stay with a practice for years.

The dental website accessibility checklist

Hand this list to your web provider and ask them to confirm each item. It's organized by the parts of a dental site patients actually use.

Images and photos

• [ ] Every meaningful image has alt text that describes it ("Dr. Lee greeting a patient at the front desk")
• [ ] Decorative images are marked so screen readers skip them
• [ ] No important information appears only inside an image, like hours or a phone number baked into a banner graphic
• [ ] Before-and-after photos have alt text describing what's shown

For more on choosing and handling images, see our guide to dental website photos.

Text and color

• [ ] Text has enough contrast against its background (light gray on white is a common failure)
• [ ] Links are distinguishable from surrounding text by more than color alone
• [ ] Text can be enlarged to 200% without breaking the layout or hiding content
• [ ] Headings are used in order (## before ###) to structure the page, not just to make text bigger

Keyboard and navigation

• [ ] Every link, button, menu and form field can be reached and used with the Tab key
• [ ] A visible focus outline shows where you are on the page
• [ ] Dropdown menus open and close with the keyboard
• [ ] A "skip to main content" link lets keyboard users bypass the menu
• [ ] Nothing traps the keyboard, such as a pop-up you can't close without a mouse

Forms and online booking

This is where dental sites most often fail, and it's the part that matters most for getting patients in the door.

• [ ] Every form field has a visible label, not just placeholder text that disappears when you type
• [ ] Required fields are marked in text, not only with a red asterisk or color
• [ ] Error messages explain what went wrong and how to fix it ("Enter a 10-digit phone number")
• [ ] The online booking tool can be completed with a keyboard and a screen reader
• [ ] Date pickers have a keyboard-friendly alternative or text entry
• [ ] CAPTCHAs, if used, have an accessible alternative
• [ ] Session timeouts give a warning and a way to extend

Third-party booking widgets and payment tools are part of your site from the patient's point of view. Ask those vendors for their accessibility documentation, often called a VPAT or accessibility conformance report. Our guides to dental lead forms and online booking cover what else to look for.

Video and audio

• [ ] Videos have accurate captions (auto-generated captions are a starting point, not a finished product)
• [ ] Videos don't autoplay with sound
• [ ] Any audio-only content has a transcript
• [ ] Animations and sliders can be paused

Documents

• [ ] New patient forms offered as PDFs are accessible, or there's an accessible online alternative
• [ ] Insurance, financing and policy information is published as web pages rather than only as scanned images

Mobile

• [ ] The site works with phone screen readers (VoiceOver on iPhone, TalkBack on Android)
• [ ] Buttons and links are large enough to tap accurately
• [ ] The site works in both portrait and landscape orientation

Many of these overlap with good mobile design in general, which we cover in why your dental website has to work on a phone first.

About accessibility overlays and widgets

You've probably seen them: a small icon in the corner of a website that opens a menu for adjusting text size, contrast or "accessibility mode." Some vendors market these as a one-line fix for ADA compliance.

Be skeptical. Overlays can't repair problems in the underlying code, like unlabeled form fields or a booking tool that doesn't work with a keyboard. Many disability advocates and accessibility professionals have criticized them, and having one installed hasn't stopped businesses from receiving demand letters. The FTC has also taken action against at least one overlay vendor over its marketing claims.

An overlay isn't necessarily harmful as an extra, but it's not a substitute for fixing the site. Spend the money on remediation instead.

How to test your site

You don't need to be technical to do a first pass.

1. Unplug your mouse. Try to book an appointment using only Tab, Shift+Tab, Enter and the arrow keys. If you get stuck, so will patients who rely on a keyboard.
2. Run a free automated checker. Browser extensions and tools built on the WCAG guidelines will flag missing alt text, contrast problems and unlabeled fields. Automated tools catch only some issues, but they find the obvious ones fast.
3. Turn on your phone's screen reader and listen to your homepage. Does it make sense? Does the booking button announce itself clearly?
4. Zoom to 200% in your browser and see what breaks.
5. Hire an audit if you want confidence. A professional accessibility audit includes manual testing with assistive technology and produces a prioritized fix list.

Then fix the issues, retest, and repeat whenever you add new pages or tools.

Publish an accessibility statement

An accessibility statement is a short page that says you're committed to accessibility, names the standard you're working toward, and gives patients a way to report problems or request help, such as a phone number and email. It isn't a legal shield, but it shows good faith and gives patients a path other than a complaint.

Make sure someone actually reads and responds to messages sent through it.

If you get a demand letter

Don't ignore it, and don't panic. Contact an attorney familiar with ADA website claims before responding. Meanwhile, document what you've already done and start an audit if you haven't. Your web provider should be able to tell you what standard the site was built to and what testing was done.

Frequently asked questions

Do dental websites have to be ADA compliant?

The ADA requires businesses open to the public to provide equal access, and many courts have applied that to websites connected to physical locations like dental offices. There's no specific federal technical standard for private business websites yet, but WCAG 2.1 AA is the commonly used benchmark. Check with an attorney about your specific situation.

What is WCAG and which level should my dental website meet?

WCAG is the Web Content Accessibility Guidelines, published by the World Wide Web Consortium. It has three levels: A, AA and AAA. Level AA of WCAG 2.1 or 2.2 is the usual target for business websites and covers the most important barriers without being impractical.

Will an accessibility widget make my dental website ADA compliant?

Not by itself. Overlay widgets can't fix underlying problems like unlabeled forms, broken keyboard navigation or inaccessible booking tools. Businesses with overlays installed have still received demand letters. Fix the site's code and content directly.

How much does it cost to make a dental website accessible?

It depends on how the site was built and how many issues it has. A site built with accessibility in mind from the start may need only minor fixes. An older site with an inaccessible booking tool or theme may need significant work, and sometimes rebuilding costs less than repairing. Get an audit and quotes before deciding.

Who is responsible for accessibility, my practice or my web developer?

Legally, the business that operates the website is usually the one that receives the complaint. In practice, your developer does the work. Put accessibility requirements in your contract, name the WCAG level, and ask the provider to document testing.
