A dental health advocate who recently pulled six teeth out of a 17-month-old told South Wairarapa District Council that putting fluoride in the water could reduce preventable oral health issues.
South Wairarapa's water supply is not fluoridated, although Masterton's supply is.
Regional public health representatives spoke to South Wairarapa District Council last week about the benefits of adding fluoride, particularly for children.
Oral health clinical director Neil Stevens said those affected by poor dental hygiene are generally those who could not afford to remedy it.
Mr Stevens told the council he pulled six teeth out of a 17-month-old child recently.
