An article about the toxicity of toothpaste was published in MedlinePlus (the magazine of the US National Library of Medicine). The warning is right there on the label: "Seek immediate medical help if you ingest toothpaste." If the toothpaste contains fluoride, results can be serious—convulsions, difficulty breathing, and heart attack (amongst other scary side effects).
Rather use no toothpaste than fluoride toothpaste. Even if you do not swallow the toothpaste, small amounts mix with saliva and is also absorbed through the skin. These are only a few of the many other healthier available choices. The easiest is to make your own.
