We are alive mainly due to the work of our immune system – without it we could die from the weakest cold. And despite its generally recognized status as the main defender of the body, there are still times when her work can harm us. Thus, molecular biologists from the University of Toronto, Canada, today presented their new and unique research on how overly active and “fanatical” immune cells, in the fight against oral bacteria, can harm our own teeth by creating cracks and in generally weakening the dental makeup over time and as the person ages.
In fact, similar studies were carried out earlier, but despite approximately the same results, they did not allow looking into 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 on the teeth — during their effective fight against bacteria can compromise the integrity and strength of the dental structure.
Scientists conducted an analytical observation and found that neurotrophiles themselves do not threaten either enamel or filling material inside the tooth – however, after the oral cavity bacteria release acid as a product of their waste, they oxidize the enamel, which causes such a destructive effect neurotrophilia on it – the substances they already produce react with enamel and weaken it additionally, which essentially opens access to the internal filling material to by-products – which is explained so the fact of the gradual degradation of the teeth over time and as we age.
However, scientists note that those people who systematically look after and check their teeth have much less chance of experiencing similar problems, because for such a devastating effect neurotrophilism requires at least several hours of continuous reaction aimed at enamel and filling material – and therefore protected from this is quite possible!
