with two levels of bristles that clean the teeth on the exposed surfaces, along and below the gum line and between the teeth. Deeper and gentler cleansing for healthier gums. The PROfessional toothbrush is recommended: When you have red, swollen or bleeding gums (symptoms due to gum problems). Red, swollen or bleeding gums (symptoms due to gum problems) are due to plaque debris that has not been removed properly, especially from hard-to-reach areas of the mouth. The best toothbrush choice for those who want to have healthier gums: Conical bristles provide deeper penetration for more substantial cleansing along and below the gum line and between the teeth. Two-level bristles clean the teeth on exposed surfaces, along and below the gum line and between the teeth. Sloping bristles ensure easy access between the teeth by brushing the tooth surface in different directions. The non-slip Quad-Grip handle allows for a better brushing technique (modified Bass technique), as recommended by dentists, creating a 45 ° angle for the best possible cleaning below the gum line.
