Commonly Used Techniques

Restorations: Steps involved in placing a restoration for your child.

How it's done...

Step 1

First, your child is made to feel comfortable in the dental chair, some children are anxious and appropriate behaviour managing techniques are used.  A technique called Tell-Show-Do is used, where the procedures are explained in steps in language which they can comprehend, the step is shown (usually on their hand) and then the procedure is conducted.

Another technique – distraction is also used.  This involves constantly talking to your child and involving their imagination in the conversation.  Distraction is also used by your child watching a movie on the ceiling screen.

Words such as “needle, injection, drill and hurt” are never used.

Step 2

Topical Gel

Topical Pellet

Topical anaesthetic is placed on the gums - this is a cream that numbs the gums to allow a painless local anaesthetic to be given. 


The cream is kept on the gums for 3-5 mins.

Step 3

LA Wand

The local anaesthetic that we use is computer assisted and called “The Wand”.  The major advantages are that it does not look like a fearful syringe, and the flow of the solution is controlled to be expressed drop by drop.  This makes the anaesthetic very comfortable.  Many children do not know they have had an injection.

Step 4

Handi Dam

Rubber dam is used.  This is a sheet of rubber with holes punched out so the teeth poke through the holes.  Advantages:  isolates the teeth we are working on, reduces saliva moisture (this is very important to allow white restorations and sealants to stick properly), protects the soft tissues and reduces the risk of anything falling down the airway.  The rubber is held in place by a metal ring around the tooth.

Step 5

The cavity is cleaned with a highspeed and slowspeed handpiece.  Decay is removed.

Step 6

Depending on the size of the decay, the most appropriate material is chosen.  Generally this is a tooth coloured restoration.  If on a baby tooth the decay is extensive and deep or the tooth has had a pulpotomy, a stainless steel crown is placed.

Step 7

Decay in between teeth - when the decay on one tooth has been removed the adjacent tooth surface is inspected for decay.  If present this is removed and restored with a white filling.  *Decay is a bacterial infection which spreads from one tooth surface to another contacting surface.

Step 8

Band On Tooth

Band On Tooth

A matrix band is placed around the tooth and secured.  The cavity is etched and bond resin applied to allow a better adhesive restoration.  The restoration is built up in three layers for optimal strength and aesthetics.

Step 9

The matrix band is removed.  Margins of the filling polished.

Step 10

Step 10: Floss Thru

Floss placed between the teeth with a fluoride varnish.

Step 11

Rubber damn removed.
