In the process of oral treatment, in order to prevent cross-infection, doctors will ensure that the tools and equipment used are properly disinfected. This includes tools such as drill bits, which may come into contact with the patient's blood or saliva, so they need to undergo a professional disinfection process.
But please rest assured that the doctor will ensure the safety and hygiene of patients during oral treatment. If you have any questions or concerns about the disinfection measures in the hospital, you can ask a doctor or consult relevant disinfection procedures and records.
