Most babies start teething at around 6 months, but some may start as early as 3 months or as late as 12 months. In rare cases, babies may be born with one or two teeth or have a tooth emerge within the first few weeks of life. The first teeth to come in are usually the lower front teeth (the lower central incisors), followed by the upper front teeth (the upper central incisors) . Here is a rough guide to how babies teeth usually emerge:

• Bottom incisors (bottom front teeth) – these are usually the first to come through, usually at around 5 to 7 months.
• Top incisors (top front teeth) – these tend to come through at about 6 to 8 months.
• Top lateral incisors (either side of the top front teeth) – these come through at around 9 to 11 months.
• Bottom lateral incisors (either side of the bottom front teeth) – these come through at around 10 to 12 months.
• First molars (back teeth) – these come through at around 12 to 16 months.
• Canines (between the lateral incisors and the first molars) – these come through at around 16 to 20 months.
• Second molars – these come through at around 20 to 30 months.

Teething symptoms can vary from baby to baby, but they may include swollen and tender gums, fussiness and crying, a slightly raised temperature, gnawing or wanting to chew on hard things, lots of drool, coughing, and rubbing their cheek or pulling their ear. Teething can be uncomfortable, but if your baby seems very fussy, talk to your doctor.
