Editor: Last week I read two letters to the editor from citizens in the dentistry field that were concerned about fluoridation being halted permanently in Healdsburg. The only reason the halt could be permanent is if fluoride ingestion cannot be proven safe. If it is safe, there should be no worries about Measure T passing, because fluoridation will resume once safety proof is provided. So what this says to me is that there may be no proof. Vote yes on Measure T to ensure our safety.
