The term GROWING CANINES refers to the process of teething, which is when a baby's first set of teeth start to emerge. Teething is a natural process that usually begins around 6 months of age and can last until the child is 3 years old. During this time, the baby's gums may become swollen and tender, and they may experience discomfort or pain. The growing canines are the first teeth to appear during the teething process.
