Hello, I would like to ask the doctor, to the hospital to wash teeth with what method to wash good, I heard that the hospital is now using ultrasonic cleaning method, but this will be infectious diseases?
Not to be choked, the purpose of scaling is to prevent and control oral diseases, and focus on prevention. The current ultrasonic cleaning is the safest, and requires each working tip to be easily removable for sterilization. Manual scaling is more complex and uses more tips than ultrasonic scaling, and if that's a concern for you, there's a greater chance of cross-contamination.
We have to admit that hand work can sometimes be more delicate than machine work. But for a routine operation like scaling, the efficiency of the work is still commendable. As for life digital scaling, I haven't heard of it.
