How often do you really need a check-up?

Where six months came from

The six-month recall is tradition more than science. UK guidance (NICE) has said for two decades that the interval should be set for the individual: as short as three months where the risk of trouble is high, and up to two years for adults whose mouths are consistently healthy [1].

What decides your interval

At each examination your dentist should set the next interval deliberately, weighing things such as:

• How much dental work you already have — fillings and crowns age, and are watched
• Your gum health — bleeding, deep pockets and bone loss all shorten the interval
• Your decay risk — diet, dry mouth, and how the last few years have actually gone
• Smoking and alcohol, which raise the stakes for the soft-tissue screen
• Changes in your life — pregnancy, new medication, illness — that change your risk

Why the visit matters even when nothing hurts

Almost everything a check-up looks for is silent at the stage it is best treated: early decay, early gum disease, a filling starting to fail, and changes in the soft tissues of the mouth. The mouth-cancer screen in particular takes a minute — and it is the one part of the examination you cannot do for yourself [2].

The honest summary

If your mouth is healthy and your record is boringly good, you may genuinely need to be seen less often than every six months — and your dentist should be willing to say so. If your gums bleed or your teeth carry a lot of old work, being seen more often is not upselling; it is how small problems stay small.
