Introduction:

Aging is an inevitable and progressive process that currently constitutes a serious sociodemographic problem, where its high numbers constitute a challenge for the health system.

Objective:

To update knowledge about the relationship between systemic diseases and oral diseases in the elderly.

Methods:

A literature review was conducted between April and July 2021.

Its relevance and novelty were taken into account in correspondence on the subject.

Results:

Aging is marked by the occurrence of systemic and oral diseases, where there are numerous published works that show that one of them can influence, being a cause or a consequence, in the development of the other.

Conclusions:

It is important to know the bidirectional relationship between systemic diseases and oral diseases in the elderly, requiring greater care and systematic attention in these patients.
