Fluoride overdoses can occur intentionally or by accident. Acute overdoses are rare and fatalities are extremely rare. Overdoses primarily occur in children under the age of six, and most commonly occur due to ingesting too much toothpaste, mouthwash, or oral rinses. However, there are industrial sources of fluoride, such as some pesticides and rodent poisons, that if ingested at extremely high doses, can also cause a fluoride overdose. Normally, the effects of a single exposure to an excessive amount of fluoride are typically not serious in the long term.
Children should never intentionally swallow toothpaste or rinses that contain fluoride. You should always assist children when using products containing fluoride to ensure that your child does not ingest too much. When your child finishes brushing, make sure they rinse their mouth thoroughly with clean water and spit out everything. Symptoms of acute fluoride overdose may include:
