Replace your toothbrush every 3 months.
The stiffness of toothbrush bristles is basically categorized as soft, medium and hard, although there are additional types such as extra soft. Unless your dentist recommends another type of bristle, most people are better off using soft or extra soft toothbrushes. The stiff bristles, as well as some medium ones, of the toothbrush can be hard on the gums, causing them to wear out. This can lead to the need for extensive and expensive dental treatment to repair the damage to the gums. Toothbrush bristles vary in length – many have one height, while others feature staggered bristle lengths designed to fit uneven tooth surfaces.
Toothbrush bristles range from hard to extremely soft.
A battery-powered toothbrush usually has short bristles. The bristles on toothbrushes in all types of styles are usually in straight, regular rows, but with triangular-shaped brush heads, the pattern will be different. Some triangular toothbrushes can adjust to different angles, like dental instruments, to better reach the back of your mouth and between your teeth.
Both types of natural and synthetic toothbrush bristles are available today, although synthetics are much more common. Nylon and polyester are the main synthetic materials used in toothbrush bristles. Some brands of designer toothbrushes feature thick boar hair bristles. Before synthetics became the norm for toothbrush bristles, boar and horsehair bristle types were used only. Natural bristles may not be as resistant to bacteria as synthetic ones; moreover, they are more likely to fall from the bush.
Hard toothbrush bristles can be hard on your gums.
While many toothbrush bristles are white or off-white, they can be any color. Some types of toothbrushes that combine different bristle heights mean each level with another color. Regardless of the type of bristles on a toothbrush, all types of bristles tend to flatten out within a few months. Toothbrushes used daily should be changed at least every three months, according to many dental experts.
Not changing your toothbrushes often enough can make it difficult to remove the plaque that causes tooth decay.
The more toothbrushes you use, the more the bristles become flattened and spread out rather than straight to better clean your teeth. Just like a home brush used to clean stubborn stains, flat or crushed bristles from toothbrushes don’t work as well as vertical bristles. Without changing toothbrushes every three months or earlier, users run the risk of not being able to brush their teeth properly and also effectively remove the sticky film called plaque that can build up on the surface of their teeth and cause cavities. When choosing a suitcase to hold a toothbrush, care must be taken to find one that does not crush the bristles. Cheap travel folding toothbrushes may be of inferior quality; it may be better to buy a good brush with soft bristles.
