no, mammals are not the only ones with teeth, there is also alligators and crocs, sharks, dolphins, some fish.
Another way to read the question is - do mammals have teeth only?
The answer is no - some mammals have just a long, sticky tongue for catching ants and termites. Echidnas, for example, do not have teeth. Some mammals such as the platypus have grinding plates instead of teeth.
Milk teeth would, by definition only occur in mammals, since mammals are the only animals that produce milk for their young. Other animals may well have a set of deciduous teeth that are replaced by adult teeth as they mature.
Starfish are echinodorms, they are not mammals and do not have teeth.
Usually, yes, but there are exceptions. For example, baleen whales have teeth as embryos, lose them, and never replace them. Anteaters, pangolins, and echidnas never have teeth. No mammals replace their teeth twice during their lives.
There are several mammals which do not have teeth. The echidna is an Australian mammal, a monotreme which only has a sticky tongue. The platypus is another Australian monotreme which has grinding plates, rather than teeth. Sloths, anteaters, tamanduas, pangolins, baleen whales, and adult monotremes are all toothless mammals.
this is called replacement
Animals with hooves usually have flat wider teeth for grinding in back of the mouth and roundish front teeth for pulling. Members of the deer family have only bottom front teeth.

teeth that havn't been brushed
Mammals are a large group of species that eat all types of food...their teeth are specialized.
The land mammal with the fewest teeth is the armadillo. It has just a few peg-like molars. However, apart from some mammals which have no teeth at all (such as anteaters, echidnas and platypuses), the mammal with the fewest teeth is the narwhal. A marine mammal, the narwhal has just two teeth. These teeth are not inside the narwhal's mouths, but are buried in their upper jaws in both males and females. Only one tooth is visible, and that is the left tooth of the male, which can grow to around 2.4 metres.
They i dont know lolim not really sure
Because of the shape of the teeth
