High fluoride toothpastes, such as Prevident 5000, are recommended for children:*Ages 1 year and olderWith high caries riskWho don't like fluoride varnishOnly if they don't drink fluoridated water

High fluoride toothpastes, such as Prevident 5000, are typically recommended for children who have a high risk of developing caries (tooth decay). This is because fluoride is a mineral that can help prevent caries by making the tooth more resistant to acid attacks from plaque bacteria and sugars in the mouth.

Here are the steps to answer the question:

1. Age: The American Dental Association (ADA) recommends using fluoride toothpaste for children starting at age 2. However, it's important to use only a pea-sized amount and to ensure that the child does not swallow the toothpaste.

2. Caries Risk: High fluoride toothpastes are recommended for children with a high risk of caries. This could be due to a number of factors, including poor oral hygiene, frequent snacking on sugary foods, and a history of previous cavities.

3. Fluoride Varnish Preference: Some children may not like the taste or feel of fluoride varnish, which is often applied during dental visits. In these cases, a high fluoride toothpaste can be a good alternative.

4. Fluoridated Water: Even if a child drinks fluoridated water, they may still benefit from using a high fluoride toothpaste, especially if they are at high risk for caries. However, it's important to discuss this with a dentist, as too much fluoride can lead to a condition called fluorosis, which can cause discoloration of the teeth.

In conclusion, high fluoride toothpastes like Prevident 5000 can be beneficial for children who are at high risk for caries, regardless of their age, their preference for fluoride varnish, or whether they drink fluoridated water. However, it's always best to discuss these decisions with a dental professional.
