Infection control is the one thing patients worry about abroad and almost never actually check. The reassuring part is that it is visible, and you are entitled to look.
What you can simply see
Instruments should arrive at your chair in sealed pouches, opened in front of you. Those pouches carry an indicator strip that changes colour once sterilisation has run correctly.
If instruments are already laid out on a tray when you sit down, ask when they were opened. It is a completely normal question.
What to ask about
Ask whether they run an autoclave with a vacuum cycle, and whether they do biological spore testing to confirm it actually kills organisms. Chemical strips confirm the cycle ran; spore tests confirm it worked.
Ask how handpieces are processed between patients. Handpieces need to be heat-sterilised, not just wiped, and this is a genuine differentiator between careful and careless practices worldwide.
Water lines
Dental units carry water through narrow tubing where bacterial biofilm can form. A practice that treats waterline disinfection as routine, and can tell you what protocol it follows, is paying attention to something most patients never consider.
Why we would rather you asked
None of this is secret and none of it is rude to ask. A clinic that is doing it properly has spent real money on it and is generally pleased that someone noticed.
The response you get tells you at least as much as the answer does.
Ask to see the sterilisation area. Anywhere in the world, willingness to show it is among the more reliable signals you can get in a single visit.
