This is a story no one really wants to hear, but we will tell it anyway, and
you will not soon forget it.
Masks and gloves are indispensable when fighting cross-contamination.
Never visit a dentist who works without gloves.
But when gloves are used incorrectly they only protect the dentist and not you.
Gloves can be a perfect way to spread bacteria throughout the entire surgery.
DID YOU EVER HAVE THE NERVE TO LOOK
You might get that opportunity if your dentist has to pick up the phone.
THE HIGH-SPEED DRILL
The high-speed drill or airotor is beyond any doubt the most fearful weapon out of a dentist's armory.
It is air-driven, makes about 400.000 rpm. and produces a dreadful sound.
The water used for cooling is heavily contaminated in many dental surgeries.
High-speed drills are basically small turbines driven by compressed air.
83.5 % of all dentists interviewed did not clean, sterilise or disinfect these drill heads according to the official guidelines.

Cooling- and spray water in dental equipment often contains ten thousand times more micro-organisms than our domestic tap-water. ( visit -links)
Later we will discuss the problem of contaminated water in dentistry in more detail.
THE LOW-SPEED DRILL
WATER / AIR SYRINGES
Water-air syringes can deliver a stream of water, a stream of air or, when combined, an air-water spray.
Syringes often contain heaters to produce a comforting warm-water spray. But unfortunately exactly those temperatures in wich Legionella bacteria families thrive.
Plaque can be removed by a small vibrating chisel in a process called ultrasonic cleaning.
When this cooling water is contaminated it will produce a contaminated spray, just at the gateway to your respiratory system: your mouth.
