Dental extraction for caries is the most common reason for children aged 6-10 years to be admitted to hospital. Community Water Fluoridation (CWF) is safe and effective at reducing dental caries. It is most effective where there is more deprivation. However, many deprived areas do not have CWF despite Public Health England recommending it. Those who lobby against fluoridation do so using emotionally charged language and misinformation. We discuss the benefits of fluoridation and the specious arguments used against this important public health measure. The National CWF Network is led by dentists and promotes CWF. COVID-19 has led to the suspension of routine dentistry, renewing the urgency of implementation of CWF. Professional bodies such as the Royal College of Paediatrics and Child Health are urged to give their support.
