Immune cells can be a factor in the occurrence of dental cracks.

We are alive mainly due to the work of our immune system – without it we could die from a weak cold. And despite her generally recognized status as the main defender of the body, there are still cases when her work can harm us. So, molecular biologists from the University of Toronto, Canada, today presented their new and unique study on how overly active and “fanatical” immune cells in the fight against oral bacteria can harm our own teeth, creating cracks in generally weakening the dentition over time and as a person ages.

In fact, similar studies were carried out earlier, however, despite approximately the same results, they did not allow to look at the root of the problem. And the root of the problem lies in the fact that the so-called neurotrophils – immune cells produced by the immune system to fight bacteria that accumulate in the oral cavity and teeth – during their effective fight against bacteria can violate the integrity and strength of the dental structure.

Scientists conducted an analytical observation and found that the neurotrophils themselves do not threaten either the enamel or the filling material inside the tooth – however, after the bacteria in the oral cavity release acid as a product of their waste, they oxidize the enamel, which causes such a devastating effect neurotrophylls on it – substances already released by them react with enamel and weaken it additionally, which essentially opens up access to internal filling material for by-products – which explains so the fact of the gradual degradation of the teeth over time and as we age.

However, scientists note that those who systematically care and check their teeth have much less chance of experiencing such problems, since for such a destructive effect, neurotrophils require at least several hours of continuous reaction aimed at enamel and filling material – and therefore protect themselves from this it is quite possible!
