My son got his first tooth at 4 months and I was completely unprepared. My daughter did not get her first tooth until she was 11 months and I spent several months convinced something was wrong. Both are now completely fine with full sets of teeth. Baby teeth, also called primary or deciduous teeth, come in a fairly predictable order though timing varies enormously between children. The general sequence: lower central incisors are usually first, typically arriving between 6 and 10 months. Upper central incisors follow shortly after, usually between 8 and 12 months. Lateral incisors on both top and bottom come next, usually between 9 and 13 months. First molars arrive between 13 and 19 months. These are the back teeth and their arrival can cause significant discomfort because of their large flat surface area. Canine teeth, the pointy ones between the front teeth and molars, usually appear between 16 and 22 months. Second molars, the final baby teeth, typically arrive between 23 and 31 months completing the set of 20 primary teeth. Signs of teething include increased drooling, gnawing on objects, irritability, disrupted sleep, and red swollen gum tissue where a tooth is emerging. Fever, diarrhea, and rashes are not caused by teething despite common belief. If your baby has a temperature over 38 degrees, look for another cause. Teething remedies that help: cold teething rings, cold damp washcloths to chew on, gentle gum massage. Teething gels containing lidocaine are not recommended for infants. Start brushing as soon as the first tooth appears, twice daily with a tiny smear of fluoride toothpaste.
