Losing Teeth. Between the ages of three months and seven months, a puppy begins to lose its deciduous teeth. Each deciduous tooth root will generally be absorbed by the adult tooth, though there are instances where this does not properly occur.At three months, the incisors begin to fall out to make room for the new adult teeth.etween the ages of six and seven months, the adult molars will come in. Finally, by seven to eight months, the full set of adult teeth should have come in.ConsiderationsBy the time a puppy is eight months old, it should have a full set of a total of 42 teeth, but some breeds have more or fewer.
