A puppy’s teeth start appearing when he is about four weeks old. These are deciduous (temporary) or baby teeth that do not have roots. By the time the young dog is about six weeks old, most of the deciduous canine, incisive and molar teeth are in place. As puppies are liable to bite their mother’s nipples, puppies are generally weaned as soon as the first set of teeth start appearing.

Being deciduous teeth, these teeth start falling off as the roots of the permanent teeth start pushing upwards. The process of replacement is usually complete by the time the dog is about eight months old. The incisors are the first deciduous teeth to fall off and the molars are generally the last.

When the deciduous teeth are being replaced by permanent ones, is when dog owners start observing the first signs of canine bad breath. Bad dog breath in puppies during this time is normal and can be easily addressed with a dog oral breath spray.

The exact timing when the temporary teeth are shed varies from breed to breed and in most cases, the owners are not even aware of the process that is taking place. This is mainly because of the fact that the temporary teeth are swallowed with food and do not really fall out.
