## What this page cannot confirm

- Whether any of these practices is accepting new patients, or treats emergencies\. This comparison does not report either: Xona reads them off a clinic's own words, and that reading is not reliable enough to line up side by side\.
- Prices, wait times, and anything about quality of care\. Xona does not assess them at all, on any page\.
- Anything shown as — or “no supported source”\. That means Xona found no supported statement of it on that clinic's own site, not that the clinic lacks it\.
- A further 28 dental practices are known in St\. Catharines, ON whose own websites Xona has not read yet, either because they publish none or because the crawl has not reached them\. They are not listed above, and their absence is not a judgement about a clinic\.
- Opening hours for 21 of the 76 practices listed here: Xona found no supported statement of them on the clinic's own site\.
