How to Run an ADA Compliance Audit on Your Dental Website

ADA website accessibility lawsuits against healthcare providers have increased significantly since 2017. Dental practices are a consistent target because their sites collect patient information, include booking forms, and often carry outdated designs that fail basic WCAG requirements. This guide walks through how to run a proper ADA compliance audit on your dental website, which free tools to use, and what to fix first.

Why Dental Websites Face ADA Compliance Liability

The Americans with Disabilities Act does not mention websites by name. The statute was written in 1990, before the web existed. But federal courts have consistently ruled that websites operated by places of public accommodation (which includes dental practices) must meet accessibility standards. The Department of Justice issued formal guidance in March 2022 confirming that ADA requirements apply to websites and that WCAG 2.1 Level AA is the appropriate compliance standard.

The volume of ADA website lawsuits has grown substantially. Healthcare was one of the top three most-sued industries in 2023. Most cases follow a predictable pattern: a plaintiff using a screen reader or keyboard navigation attempts to use a business’s website, encounters barriers that prevent access to booking, information, or services, and files a lawsuit under Title III of the ADA.

Settlement costs for ADA website cases typically range from $10,000 to $90,000 including legal fees, plus the cost of remediation. The remediation cost alone for a website that was not built with accessibility in mind often runs $5,000 to $20,000. Running an audit now and fixing the failures proactively costs a fraction of either number.

What WCAG 2.1 AA Requires on a Dental Website

WCAG 2.1 Level AA is organized around four principles: perceivable, operable, understandable, and robust. For a dental website, the most commonly tested and most commonly failed requirements are:

Free Tools to Run an ADA Audit on Your Dental Website

You do not need expensive software to start an ADA compliance audit on your dental website. Three free tools catch the majority of technical failures quickly.

• WAVE (wave.webaim.org): Enter any page URL and WAVE shows you a visual overlay of accessibility errors directly on the page. It flags missing alt text, low contrast text, empty links, and form labeling issues. Run it on your homepage, your appointment booking page, and at least two service pages. WAVE is the fastest tool for a first pass.
• axe DevTools (browser extension): The free axe extension runs inside Chrome DevTools and identifies WCAG violations on the current page. It groups findings by severity (critical, serious, moderate, minor) and shows you the specific HTML element causing each violation. More technical than WAVE but more detailed in its findings.
• Google Lighthouse: The Accessibility audit in Lighthouse runs directly in Chrome (open DevTools, click the Lighthouse tab, check Accessibility, run the audit). It scores 0-100 and lists specific failures with remediation guidance. Lighthouse accessibility and the SEO and performance audits run simultaneously, which means you can see whether accessibility issues correlate with your speed and ranking problems at the same time.

These tools together catch approximately 30% of WCAG 2.1 AA violations automatically. The remaining 70% require manual testing. The most important manual checks for dental websites are keyboard navigation (tab through the entire page and booking flow without using a mouse), screen reader testing (use NVDA on Windows or VoiceOver on Mac to navigate your site), and color contrast verification on any custom-colored elements that automated tools cannot reliably detect.

The Most Common Dental Website ADA Failures and How to Fix Them

After running audits on dental websites across multiple states, the same five issues appear repeatedly. Fix these first and you will address the majority of your liability exposure.

1. Missing alt text on before-and-after photos and treatment images. Dental websites are image-heavy. Before-and-after galleries, treatment diagrams, and doctor headshots often have no alt text at all. Fix: add descriptive alt text to every image. For before-and-after photos, describe the clinical result and the treatment. For doctor headshots, include the doctor’s name and title. For decorative images used only for visual effect, use alt=”” to signal to screen readers that the image can be skipped.

2. Low contrast text in body copy and navigation. Many dental website designs use light gray text on white backgrounds for secondary copy, footer text, and navigation labels. If your text color and background color do not meet the 4.5:1 ratio, they fail WCAG. Use WebAIM’s Contrast Checker (webaim.org/resources/contrastchecker/) to test any color pair. The fix is adjusting the text color to a darker value until the ratio passes.

3. Booking widget not keyboard-navigable. Most third-party dental scheduling widgets are tested for visual usability on a smartphone, not for keyboard or screen reader accessibility. Tab through your booking flow from start to confirmation using only the keyboard. If focus gets trapped in a date picker or a modal window, that is a WCAG 2.1 AA failure. The fix requires either a widget upgrade from your scheduling vendor or custom JavaScript to manage focus correctly. For websites going through a full redesign, the dental website design scope should specify WCAG 2.1 AA keyboard support as a required deliverable.

4. Videos without captions. Patient testimonials, treatment explainer videos, and practice tour videos are common on dental websites. If they lack synchronized captions, they fail WCAG. YouTube’s auto-caption feature produces captions that are often inaccurate for dental terminology. Edit them before publishing or use a captioning service. Rev.com produces accurate captions at about $1.25 per minute of video.

5. Form labels that rely on placeholder text only. Many dental contact forms and intake forms use placeholder text (“Enter your first name”) as the only label for an input field. When a user clicks into the field to type, the placeholder disappears. Screen readers often fail to associate placeholder text with form fields. Fix: add a visible label element above or beside each input, or use ARIA-label attributes if the visible label is not practical in the design.

How London Psychiatry Clinic’s Accessibility-Focused Redesign Paid Off

Accessibility-focused redesigns consistently produce results beyond just compliance. When we rebuilt the digital presence for London Psychiatry Clinic, accessibility and UX improvements were central to the scope alongside SEO and technical performance. The result was 120% SEO visibility growth, a 70% engagement improvement, and 55% more conversions from the site. Making content and forms more accessible to all users also made them more usable for every user, and the conversion lift reflected that.

The dental parallel: a booking form that works for a screen reader user also works better for an elderly patient typing slowly on a phone, a patient with motor difficulties using voice control, and a new patient on a slow connection who benefits from form labels that persist visually. Accessibility improvements pay off in conversion metrics, not just compliance status. Pair your accessibility audit with a broader dental website optimization review to capture both sets of gains at the same time.

ADA Accessibility Audit Process for Dental Websites Step by Step

Here is the exact process to run a proper ADA audit on a dental website. Work through these steps in order.

• Step 1: Run WAVE on your homepage, contact/booking page, and two highest-traffic service pages. Log every error and alert. Do not fix anything yet.
• Step 2: Run Lighthouse Accessibility audit on the same four pages. Note the score and the specific issues flagged. Compare with the WAVE findings.
• Step 3: Run the axe DevTools extension on the same pages. axe catches some issues that WAVE and Lighthouse miss, particularly around ARIA roles and complex interactive components.
• Step 4: Manually keyboard-navigate your full homepage and your booking flow. Tab through every interactive element. Confirm every item is reachable and operable without a mouse.
• Step 5: Check all images for alt text using the browser’s DevTools (right-click any image, Inspect, look for the alt attribute). Flag every image with empty or missing alt text.
• Step 6: Check all videos for synchronized captions.
• Step 7: Test color contrast on any non-standard colored text elements.
• Step 8: Compile findings by severity (critical, serious, moderate) and prioritize remediation. Fix critical issues first, then serious.

Your ongoing dental website maintenance checklist should include a quarterly WAVE scan on your five most-visited pages and an annual full Lighthouse accessibility audit to catch regressions introduced by plugin updates, design changes, or new content additions.
