Periodontal disease occurs when gum disease bacteria enter and increase in the periodontal pockets, the gaps between the teeth and gums. Choosing a toothbrush that can effectively scrape dirt out of periodontal pockets will help protect your teeth from the foundation of the disease. Knowing the proper size and hardness of the bristles will also increase the effectiveness of plaque removal and prevent cavities.

hardness of hair

Toothbrush bristles come in three hardnesses: "hard," "regular" and "soft. The "regular" hardness is the most suitable for most people.

If you are only thinking about removing stains, isn't "hard" the best? However, in fact, brushing with a hard toothbrush requires a high level of technical skill. Because the hard bristles can damage the gums and scrape off the root of the teeth, no matter how gently you brush. This causes the gums to fall. This can expose the roots of the teeth and cause tooth decay and sensitivity.

On the other hand, "soft" bristles are less likely to damage the gums. The bristles are suitable for people with swollen gums or those with severe gum disease who bleed easily, but because the bristles are flexible, they spread quickly if brushed with a lot of force. In order to remove stains thoroughly, it is necessary to take a little longer time and brush carefully with gentle force.

Head size

Generally, a smaller compact size with three vertical rows of bristles is appropriate. If the head is too large, it is difficult for the tip of the bristles to reach the back teeth and other fine areas, resulting in a lot of leftover polish. Especially for women, many of them have small oral cavities, so the size of the head should be smaller than indicated.High cleaning effectiveness by choosing a smaller sizeThe following is a list of the most common types of products that can be obtained.
