Every tracker on the site is a privacy decision
Scripts installed by habit on any other website send information about health-related browsing when they run on this one.
Analytics, advertising pixels, chat widgets, heatmap tools and review embeds all transmit data about what a visitor did. On a dental site, what they did is frequently reading about a condition or a procedure.
Regulatory attention to tracking technologies on healthcare websites has increased, and the position of a private dental practice is not identical to that of a hospital system. The safe assumption is that this warrants a deliberate review rather than a default install.
The questions worth answering are practical. Which scripts are on the site, what each one collects, where it goes, and whether any of them are on pages about specific conditions or on the appointment form.
Chat widgets deserve particular scrutiny, because patients type things into them that they would not put in a form, and the transcript lives with a vendor.
This is a matter for your own counsel, and the useful contribution from a marketing side is an accurate inventory of what is actually installed. Most practices do not have one.
