Tell us about yourself!
Thanks for this excellent post. My screw near the shaft was not loose, but the gap between the coils and metal base was gone. Probably we had been pressing the toothbrush against our teeth too hard. My dentist warned us that these are absolutely the best toothbrushes as long as you brush lightly and let the vibration occur to the fullest extent. Anyway, I followed the instructions and photos below to increase the gap and fixed the problem completely, saving $120 or so. Great thinking.
