Dental Health Standards The World Health Organization (WHO) formulated the dental health standards in 198 1 as follows: 1, clean teeth 2, no tooth decay 3, no pain 4, normal gum color 5, no bleeding.

Self-examination of dental health ① Whether there is blood on the bristles when brushing teeth, and whether there is blood on the food when chewing, you can judge whether you have bleeding gums.

Self-examination of dental health ② Check the health of gums by looking in the mirror. If the gums are red and swollen with bleeding, it can be judged as gingivitis.

Self-examination of dental health ③ The teeth are loose to varying degrees, the roots are exposed, the gums are red and swollen, and there is pus. It can be suspected that there is a combined lesion of dental nerve and periodontal disease.

Self-examination of dental health ④ There is a loud breath or bad breath in the mouth, or accompanied by the above symptoms, which can be judged as possible periodontitis.

Self-examination of dental health ⑤ Toothache may be a symptom of gingivitis, pulpitis or periodontitis.

Self-examination of dental health ⑥ There is a temporary sore reaction to the stimulation of hot and cold food or the mechanical stimulation of brushing teeth, indicating tooth allergy (medically called dentin sensitivity).

Self-examination of dental health ⑥ Small cracks appear on the surface of teeth, or the surface of teeth is dim and rough, indicating that it may be cracked teeth or demineralized teeth.

Tip: If you have dental problems, you should treat them in time to prevent the problems that threaten oral health from getting worse.
