Teething is a natural process: Teething is a normal part of a child's development when their teeth start to emerge through the gums. Timing varies: The timing of teething can vary from child to child, but it typically starts around 6 months of age and continues until around 2 to 3 years old. Common symptoms: Common signs of teething include drooling, irritability, gum swelling, chewing on objects, and disrupted sleep. Soothing techniques: Provide teething rings, chilled (not frozen) toys, or gentle gum massages to help soothe your child's discomfort during teething. Dental care starts early: As soon as your child's first tooth emerges, it's important to start brushing with a small amount of fluoride toothpaste and schedule their first dental visit by their first birthday.
