What are dental cleanings (scale and polish) and why have them?
The professional cleaning of teeth is sometimes referred to as prophylaxis (or prophy for short). It’s a Greek word which means “to prevent beforehand” – in this case, it helps prevent gum disease.








How are dental cleanings done?
The dental hygienist or dentist uses specialized instruments to gently remove these deposits without harming the teeth. The instruments which may be used during your cleaning, and what they feel like, are described below.

Ultrasonic instrument
The ultrasonic instrument tips are curved and rounded and are always kept in motion around the teeth. They are by no means sharp since their purpose is to knock tartar loose and not to cut into the teeth. It is best to inform the operator if the sensations are too strong or ticklish so that they can adjust the setting appropriately on the device or modify the pressure applied.
With larger deposits that have hardened on, it can take some time to remove these, just like trying to remove baked-on grime on a stove that has been left over a long time. So your cleaning may take longer than future cleanings. Imagine not cleaning a house for six months versus cleaning it every week. The six-month job is going to take longer than doing smaller weekly jobs.

Polishing
Once all the surfaces are smooth, the dental worker may polish your teeth. Polishing is done using a slow speed handpiece with a soft rubber cup that spins on the end. Prophylaxis (short for prophy) paste – a special gritty toothpaste-like material – is scooped up like ice cream into the cup and spun around on the teeth to make them shiny smooth.

Fluoride
Your dentist may also apply fluoride. This is the final, and my favorite part of the dental cleaning! Fluoride comes in many different flavours such as chocolate, mint, strawberry, cherry, watermelon, pina colada and can be mixed and matched just like ice cream at a parlour for a great taste sensation! Make no mistake though, this in-office fluoride treatment is meant for topical use only on the surfaces of the teeth and swallowing excessive amounts can give a person a tummy ache as it is not meant to be ingested.
Fluoride foam or gel is then placed into small, flexible foam trays and placed over the teeth for 30 seconds. Afterwards the patient is directed to spit as much out as possible into a saliva ejector. The fluoride helps to strengthen the teeth since the acids from bacteria in dental tartar and plaque will have weakened the surfaces. It is best not to eat, drink or rinse for 30 minutes after the fluoride has been applied.

Is it going to be painful?
Be sure to let your dentist/hygienist know if you find things are getting too uncomfortable for your liking. They can recommend various options to make the cleaning more enjoyable.
Painful cleaning experiences can be caused by a number of things: a rough dentist or hygienist, exposed dentine (not dangerous, but can make cleanings unpleasant), or sore gum tissues.
In case you may have had painful cleaning experiences in the past, switching to a gentle hygienist/dentist and perhaps a spot of nitrous oxide can often make all the difference. You could also choose to be numbed. If you find the scaling a bit uncomfortable because the gum tissues (rather than the teeth themselves) are sensitive, topical numbing gels can be used.
