Why Dentists Need Dental Suction Unit

When a dental hygienist cleans and polishes your teeth, you can get a lot of cleaning paste in your mouth. We use the suction to help clean all of that away. Also, when dentists are do amalgam fillings, pieces of the soft amalgam can sometimes fall away from the tooth surface. We use the portable dental suction to help whisk them away.

Keeping the patient comfortable is a high priority. In response to Jeanny’s question, we suction after giving anesthetic because the anesthetic has a bitter taste, and most patients prefer to rinse out with water and use the saliva ejector. Also, if the anesthetic sits in the back of your mouth for too long, it may start to slightly numb the back of your mouth and could give the patient a gagging sensation.

During some procedures, such as white fillings, it is important that the tooth stay clean and dry. The suction helps keep the tooth dry by sucking away any saliva, blood, and water that may have accumulated around the tooth. If the cavity went below the gum-line, then it’s pretty likely that the gums will bleed during the filling.

The drill that dentists use to do fillings sprays out a lot of water to keep the tooth cool and clean. Unfortunately, that water can quickly build up in the mouth and get on the dental mirror. In order to ensure that the dentist can see the tooth while working on it, it’s necessary to use the high volume suction to suck away all of that debris.

Those are the four main reasons that I came up with as to why dentists use the dental suction. In conclusion, let’s take a look at a question that I asked my dental hygienist as a child.

I remember sitting in the dental chair in Dr. Arnold’s office as a child wondering what happens to all of the stuff that gets sucked down the suction. Maybe I was hoping that the tooth fairy would somehow be able to save the bad part of my baby tooth that the dentist removed and put it back together once my tooth fell out. After gathering up the courage to ask, I think I was slightly disappointed by the answer.

After your saliva, tooth debris, etc. gets sucked away, it travels through the suction line to a vacuum separator that will separate out any solids. After that, your spit makes a journey down the pipes and into the sewer system.

It is now recommended that dentists install amalgam separators in their suction lines to separate out any dental amalgam and keep it from getting into the public sewer systems.
