If you were to continuously brush your teeth would there eventually be a point where it would no longer be beneficial?

Yes! Not only will further brushing not help anything it will actually hurt your teeth! Brushing your teeth for long periods of time will actually damage them and make them yellow! Your tooth enamel is what is nice and white and shiny. It is a layer that protects your teeth. The layer under the enamel is called dentine and is actually yellow. So while surface stains can yellow your teeth the biggest cause of yellow teeth is loss of enamel. Excessive brushing will actually wear away your enamel and make your teeth yellow and more susceptible to damage. Also there is no way to restore enamel currently, once it is gone it is gone forever.
