Dental hygiene
The toothbrush
|
|
The toothbrush should be replaced every three months. A toothbrush for cleaning a healthy mouth should be small and soft, with a long handle to reach all corners of the mouth. The toothbrush filaments should be round-tipped to avoid harming the gums, and should be made of synthetic material (nylon is generally used), with polished tips. A brush should not be used for more than three months, since after this time the filaments have deteriorated, even if they seem to be intact upon inspection. |
