This toothbrush set with 3 different toothbrushes ensures a healthy oral development for your baby. It is of great importance to protect first teeth. The set foresees one toothbrush for each stage and was designed in favor of your child's development. The two silicone toothbrushes are perfect for applying the soothing All Natural Nby Citroganix teething gel. The natural ingredients promote a healthy dental hygiene. The first one you can introduce to your baby when he starts to feel irritations of sore gums and the first teeth are slowly coming out, that's around the age of 3 months. The gum cleaner/brush with special soft rubber plate massages gums and palate. Once the teeth really start erupting it's better to change towards the other silicone brush, that's around your baby's 6 months. This toothbrush with rubber hair cleans and softens the gums. When you see your baby's first real teeth you can switch towards the real' toothbrush with soft nylon hairs. All toothbrushes are made of safe, durable materials.
