Until recently OH always saw the hygienist every six months whilst I was never referred. However now my plaque does build up a little more and at our age it can lead to serious gum problems. Cleaning and flossing is all well and good but you do have to make sure there is no build up inside the gums.
Some hygienists use only electronic equipment and this can be a little brutal if your build up is heavier (everyone is different its down to age, health and body chemistry). However, our hygienist takes her time and uses fine manual tools which are a lot gentler - its a good half hour for just under £50 which is pretty fair for professional services. I trust my dentist, he has shown great professional judgement over the years and if he recommends the hygienist I know its for a reason.
