The term CANINE NEIGHBOR can be broken down into four crossword solutions: MOLAR (5 letters), INCISOR (7 letters), BICUSPID (8 letters), and PREMOLAR (8 letters). Molars are the largest teeth in the mouth, located at the back of the jaw and used for grinding food. Incisors are the sharp front teeth used for cutting and biting. Bicuspids are the pointed teeth located between the incisors and molars, used for tearing and crushing food. Premolars are the teeth located between the bicuspids and molars, used for grinding and shearing food. All of these teeth are found in the mouths of canine neighbors, such as dogs and wolves.
