Dentists and ads constantly push electric toothbrushes as a big upgrade that removes way more plaque and prevents cavities better than manual brushing. I have been using one for the past year and my teeth do feel cleaner but I am not sure if it is worth the extra cost long term. Friends who stick with regular brushes seem to have just as good dental checkups. Is the difference actually significant or is this complete bullshit?
