Some people will find that a small black spot suddenly appears on the surface of their teeth, but they don't feel pain. What causes the appearance of black spots on teeth? If the teeth have black spots and are painless, there are two possibilities. ?
1, pigmentation?
Such as tobacco stains, tea stains, coffee stains, etc. It is difficult to brush off when brushing your teeth and can be removed by washing your teeth. ?
2. Does the tooth have deep caries or shallow caries? Dental caries appear as black spots from the outside, usually located in pit and fissure (punctate or linear depressions on the surface of teeth). The chief culprit of dental caries is some bacteria in the mouth, but it takes time for them to destroy teeth. It usually takes 1 year and a half to two years from the initial discoloration to the final tooth cavity formation. In the meantime, we should pay more attention to our teeth, which may completely nip dental caries in the bud. How can we find this hidden tooth decay in time? Find a good dentist and check your teeth for half a year! ? Once it is confirmed that the small black spots on the teeth are dental caries, they should be repaired as soon as possible to prevent the development of the lesions. If left unchecked, it will become an obvious cavity, and patients will be sensitive to food stimuli such as cold, hot, sour and sweet; When the injury further reaches the pulp (that is, the "tooth nerve" as the people say), it will be unbearable and seriously affect daily life. ?
Clinically, many people will wait until the toothache is unbearable before going to the hospital.
