When Do Babies Start Teething? (Signs, Timeline & What to Expect)

Average Teething Timeline

Most babies begin teething between 4 and 7 months. However, some babies may start as early as 3 months or as late as 12 months.

The two bottom front teeth (lower central incisors) are usually the first to appear.

Common Signs of Teething

• Increased drooling
• Chewing on hands or objects
• Mild irritability
• Swollen or tender gums
• Changes in sleep patterns

Mild fussiness is common, but high fever is not typically caused by teething.

Does Teething Affect Sleep?

Teething can temporarily disrupt sleep. Babies may wake more often due to gum discomfort.

However, frequent night waking is often developmental rather than teething alone.

Safe Ways to Soothe Teething Discomfort

• Clean teething rings (chilled, not frozen)
• Gentle gum massage
• Cold washcloth for chewing

Always consult a pediatrician before using teething medications.

Preparing for Teething in Advance

Many parents prefer to have soothing essentials ready before teething begins. Having bibs, burp cloths, and teething rings organized can reduce stress when symptoms start.

If you’re organizing baby essentials early, some families choose to save on expensive baby gear with a baby registry to receive welcome gifts and completion discounts while planning ahead.
