To keep a healthy, radiant smile it is vital to choose your dental <a href=\"https:\/\/www.pierrotcare.com\/en\/oral-care-products\/\" target=\"_blank\" rel=\"noreferrer noopener\">hygiene products well and,<\/a> above all, to know when the time has come to say goodbye to them.<\/p>\n\n<h2 class=\"wp-block-heading\">Why three months is the &#8220;golden rule&#8221;<\/h2>\n\n<p class=\"wp-block-paragraph\">We often think that as long as the brush keeps its shape it works just as well as on day one. The reality, however, is very different. Dentists recommend changing your <strong>toothbrush every three months for a question<\/strong> of physical effectiveness: the bristles are designed to be flexible and to return to their position after each pass.<\/p>\n\n<p class=\"wp-block-paragraph\">With daily use, the nylon tires. When the tips bend or splay, they stop &#8220;sweeping&#8221; plaque away and simply slide over it. It is like trying to clean the floor with an old broom; however much effort you put in, the result will not be the same.<\/p>\n\n<p class=\"wp-block-paragraph\">At <a href=\"https:\/\/www.pierrotcare.com\/en\/\" target=\"_blank\" rel=\"noreferrer noopener\">Pierrot<\/a> we know that a brush in good condition is the first line of defence against cavities and gingivitis.<\/p>\n\n<h2 class=\"wp-block-heading\">Tips for keeping your toothbrush clean<\/h2>\n\n<p class=\"wp-block-paragraph\">For your toothbrush to reach its third month in perfect condition, it is not enough to rinse it briefly after use. Some tips for keeping your brush always clean are:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Rinse it well<\/strong>: after brushing, hold the head under a strong jet of water and rub the bristles with your thumb to remove any toothpaste or food residue.<\/li>\n\n\n\n<li><strong>Always air dry<\/strong>: never store a wet brush in a closed case or with the cap on if it has no ventilation. Damp is a paradise for bacteria\u2026 As an extra tip, always leave it upright.<\/li>\n\n\n\n<li><strong>Avoid contact with other toothbrushes<\/strong>: if you share a bathroom, make sure your toothbrush does not touch anyone else&#8217;s. Keeping that distance between heads prevents micro-organisms passing across.<\/li>\n\n\n\n<li><strong>Never share your toothbrush<\/strong>: although it seems obvious, it is more common than we think. Sharing a toothbrush is a direct exchange of fluids, bacteria and micro-organisms that can cause anything from cavities to more serious illnesses. However much affection there is, a toothbrush is strictly personal and non-transferable.<\/li>\n\n\n\n<li><strong>Weekly deep clean<\/strong>: once a week you can soak the head in a glass of antibacterial mouthwash for a few minutes to disinfect it thoroughly. <\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">How do you know when a toothbrush is no longer any good?<\/h2>\n\n<p class=\"wp-block-paragraph\">Although, as we have said, the &#8220;golden rule&#8221; is to change your toothbrush every three months, it is essential to spot the signs that the brush needs replacing:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>If the bristles are no longer straight and look &#8220;tousled&#8221;<\/strong>. When the brush is like that, instead of sweeping dirt away it just passes over it without removing anything, leaving plaque in the mouth.<\/li>\n\n\n\n<li><strong>When the bristles prick<\/strong>: at first the bristles are soft, but with washing they sharpen. If you notice that brushing hurts or your gums bleed, it is time to change your toothbrush. Carrying on with the brush in that state can scratch tooth enamel. <\/li>\n\n\n\n<li><strong>If the base of the bristles changes colour<\/strong>: this means there is a nest of bacteria in the head of your brush. If this happens, it is time to start a new one (even if three months have not gone by!).<\/li>\n\n\n\n<li><strong>After being ill<\/strong>: if you have been through an infection (flu, tonsillitis and so on), it is best to change the brush to avoid possible reinfection from the germs left in the bristles.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Now that you know <strong>when to change your toothbrush ,<\/strong>we invite you to check your current cleaning kit; if you think the time has come to replace it, you can rely on Pierrot&#8217;s experience <a href=\"https:\/\/www.pierrotcare.com\/en\/\">to find<\/a> professional hygiene tools suited to your needs.
