(see blue on above image) - These are the small teeth in the front of the mouth. There are 6 on the bottom row and 6 on the top row. These are not used for chewing, but rather are useful for picking up things up (including food but also toys and such) and for nibbling on things (including themselves; for example, when itchy).
If one or more incisors are missing, a Pomeranian can most likely still eat their regular food. Do note, however, that if an incisor is extracted, you may be directed to offer soft food while the gum heals.
Canines
(see green on above image) – Also referred to as the fangs, there are just 4 in total. These come right after the incisors, with 2 on the bottom row and 2 on the top row. The canine teeth are used to bite and hold onto things. If a dog bites a person, it is the canines that the victim will be feeling. If a Pom is missing one or more canines, they can usually still eat their regular food, but it should be bite-sized.
Premolars
(see orange on above image) – These are the type of teeth that come next after the canines; there are 16 in total, with 4 on the lower left, 4 on the lower right, 4 on the top left, and 4 on the top right.
These are the main teeth that a dog uses to chew food. Those near the front are rather small but they get progressively larger toward the back. When a dog eats, they move the food to one side of the mouth and use the premolar’s surface area and pointy ends to grind up the food into pieces small enough to swallow.
If your Pomeranian is missing premolar teeth, whether or not hard food can still be eaten will depend on how many teeth are gone and which side(s) of the mouth the remaining teeth are located.
For example, if a Pom has just one missing premolar, this would rarely affect their ability to eat. And, if two, or even three, are missing from one side, many dogs would be able to compensate for this by keeping their food bits on the opposite side.
However, if 3 or more premolars are missing, and especially if the loss is on both sides of the mouth, this most often will mean that it would be difficult to eat hard kibble and doing so could present a choking hazard.
Signs of difficulty eating due to tooth loss include coughing out pieces of food, eating very slowly, dropping food pieces to the floor only to sniff at them with half-hearted attempts to mouth them, and/or refusal to eat.
