As do you. I'll cherry pick this bit for the sheep here. ba ba ba.

Combining several methods of self-administered topical fluoride products with water fluoridation will lead to caries reduction benefits greater than when using only one method. Having a dose-response relationship, the exposure to multiple sources of fluoride, especially in lower concentrations administered daily, increases the caries reduction benefits. Combining topical fluoride products with the consumption of fluoridated water will benefit high-risk patients (28).

As with fluoridated water, there has been some concern about the simultaneous combination of fluoride ingested from both salt and toothpaste. Available data suggest that this combination has not resulted in objectionable enamel fluorosis levels. However, observations of increased mild dental fluorosis were seen in children who consumed fluoride tablets and fluoridated salt (17).

Thus, the statement that combining topical fluorides use and fluoridated water intake will cause fluorosis in the adult patient is uncertain. Fluorosis occurs only when fluoride is ingested in excessive amounts during the late secretion to the early maturation stage of enamel formation in the course of tooth development. Once tooth development is complete, any amount of topical fluoride exposure, whether in combination with fluoridated water or not, is not a risk factor for fluorosis. Children should be supervised when using topical products since swallowing some doses of these products regularly during tooth development has the potential to cause fluorosis (28).

Go to:
INCREASING OPPOSITION TO FLUORIDATION
More than 80% of fluoride toxicity is seen in children before the age of 6 years, due to ingestion of fluoride-containing toothpaste or mouthwashes (29); it is rare in adults in the developed world. Acute toxicity is characterized by nonspecific gastrointestinal disturbances such as pain, nausea, vomiting, and diarrhea (30,31). In severe cases, this may progress to renal and cardiac dysfunction, coma, and ultimately death (32). In children, as little as 8.4 mg/kg may produce symptoms (30). Chronic fluoride toxicity is usually caused by high fluoride concentrations in drinking water or the use of fluoride supplements. Chronic ingestion of high doses leads to dental fluorosis, a cosmetic disorder where the teeth become mottled (1). In more severe cases, it leads to skeletal fluorosis, in which bone is radiologically dense, but fragile. Fractures can occur, and there may be calcification of ligaments and tendons, leading to reduced joint mobility (1). The syndrome also may include extensive calcification of ligaments and cartilage, as well as the bony outgrowths of osteophytes and exostoses (33).

I say it again, I don't think we all need to go looking for products with flouride added into the ingredients from my original post.
