Puech, Mattei, Dumas, Belluzi, and others report the eruption of teeth in the newborn.

In Dumas' case the teeth had to be extracted on account of ulceration of the tongue.

Instances of triple dentition late in life are quite numerous, many occurring after a hundred years.

Mentzelius speaks of a man of one hundred and ten who had nine new teeth.

Lord Bacon cites the case of a Countess Desmond, who when over a century old had two new teeth; Hufeland saw an instance of dentition at one hundred and sixteen; Nitzsch speaks of one at one hundred, and the Ephemerides contain an account of a triple dentition at one hundred and twenty.
There is an account of a country laborer who lost all his teeth by the time he arrived at his sixtieth year of age, but about a half year afterward a new set made their appearance.
