I purchased this Butler Sulcas brush two months back and I just love using it. It can clean almost all areas of my teeth and even removes plague from the areas. I use it gently over my teeth and gums as my gums bleed if I rub the brush hard. I have found that my teeth look whiter and the dentist also has told me that my teeth do not require cleaning for the time. The best way to keep your teeth free from cavities and plague is by brushing with the Butler Sulcas brush twice a day in the morning and evening. My teeth are all in proper shape and so it becomes easier for me to move the brush in the right areas and it gets food stuck in between the teeth out easily. The price of one toothbrush is very less and I already have a set of 5 brushes for my entire family. It has soft bristles which help in preventing gum diseases and it also helps in stopping gum bleeding which is the most important factor for me.
