Ruggae are the prominent ridges on the palate (roof of the mouth) directly behind the upper front teeth.
None. Turtles have a ridge of horny tissue (sometimes called a beak) on both their top and bottom jaws. In most turtles these ridges are actually quite sharp with the lower jaw ridge sliding up and slightly behind the upper ridge.
around the upper and lower inside edges
No, alpacas do not have upper teeth. Alpacas have a soft upper gum area, which they chew their chud against with their bottom teeth. Alpacas do not have upper teeth, and grasseaters don't usually need them.
An alveolar ridge (/ælˈvi.ələr/; also known as the alveolar margin) is one of the two jaw ridges either on the roof of the mouth between the upper teeth and the hard palate or on the bottom of the mouth behind the lower teeth. The alveolar ridges contain the sockets (alveoli) of the teeth. They can be felt with the tongue in the area right above the top teeth or below the bottom teeth. Its surface is covered with little ridges. Sounds made with the tongue touching the alveolar ridge while speaking are called alveolar consonants. Examples of alveolar consonants in English are, for instance, [t], [d], [s], [z], [n], [l] like in the words time, dawn, silly, zoo, nasty and lollipop. There are exceptions to this however, such as speakers of the New York Accent who pronounce [t] and [d] at the back of their teeth. When pronouncing these sounds the tongue touches ([t], [d], [n]), or nearly touches ([s], [z]) the upper alveolar ridge which can also be referred to as gum ridge. In many other languages these same consonants are articulated slightly differently, and are often described as dental consonants. In many languages consonantsare articulated with the tongue touching or close to the upper alveolar ridge. The former are called alveolar plosives, and the latter alveolar fricatives.
always ! its easy .. and there is a grammatical mistake in your question .

Birds, in general, do not have teeth. It's an adaptation that reduces their weight, enabling flight. Falcons, however, have a tomial tooth - a notched ridge on the upper half of their beak used for severing the spinal cord of their prey - not found in other birds of prey.
baffalo has no upper teeth
The phitrum ridge is the indentation or groove that runs vertically between the nose and upper lip. Its function is primarily aesthetic and individual variations in the phitrum ridge contribute to facial appearance.
Maxillary teeth.
