Should i be using mouthwash with fluoride toothpaste?

You can: As long as you are not swallowing lots of the mouthwash and/or toothpaste it is no problem and it may help keep your tooth enamel healthy. You can not over-do topical Fluoride appllied to the surface of teeth in your mouth. Too much systemic (swallowed) Fluoride is not good although you would need to swallow a lot for it to be a problem.

Fluoride: Research shows that Fluoride helps prevent cavities in children and adults by making teeth more resistant to the acid attacks that cause cavities. Fluoride helps rebuild (remineralize) weakened tooth enamel and reverse early signs of decay. When you brush your teeth with Fluoride toothpaste, or use other Fluoride dental products, you are providing a “topical” benefit.

Sure: As long as your not using them at the same time. You can even use a mouthwash that has Fluoride in it.

Yes that is okay: But remember the best mouth was is salt and water.

Definitely, yes: Fluoride mouthwashes are excellent in helping prevent tooth decay and great t use after brushing with sensitivity toothpaste.
