Background The dental health of children in the UK has improved in the past 30 years, but tooth decay can still be a problem in children under five, especially those from deprived areas.

Conclusion Nurses and health visitors have a role in promoting oral hygiene in young children. Simple advice to parents on brushing their children’s teeth, appropriate use of feeding bottles and visiting the dentist regularly is the key to further improvement in the oral health of young children. Particular attention should be paid to underprivileged children.
