It requires explanation and consent
Before starting, the practitioner should explain the process, hygiene and possible sensations.
This stage should never happen without clear consent.
It is not compulsory
Intraoral work may be omitted because of comfort, health or preference.
The session can still remain complete.
Hygiene and consent are especially important
Work inside the mouth requires gloves, a clear explanation and separate consent.
You may decline this technique and the plan should be adjusted without pressure.
