• If you used foul language, some parents will wash your mouth out with soap. But that's not the only cause of a soapy taste in your mouth.

    Not Rinsing Properly

    Many people brush their teeth in a rush and don't rinse their mouth out properly. Leftover fluoride can cause your mouth to feel soapy.

    Too Much Fluoride

    Consuming too much fluoride will cause you to feel like your mouth is full of soap. This can be from drinking too much tap water or brushing with toothpaste that contains large amounts of fluoride.

    Fluoride Poisoning

    Fluoride poising can cause you to have a soapy taste in your mouth. Fluoride poison victims also experience symptoms such as vomiting, upset stomach and diarrhea.

    Fluoride Treatments

    Too many fluoride treatments at the dental office will also cause you to have a soapy mouth.


    If you are experiencing a soapy mouth, you should reduce your fluoride intake. If you experience additional symptoms that are associated with fluoride poisoning, you should consult with a doctor immediately.
