Teething

A child’s teeth actually start forming before birth. As early as 4 months of age, the primary or “baby” teeth begin to push through the gums—the lower central incisors are first, then the upper central incisors. Normally the first tooth erupts between ages 6 to 12 months. Gums are sore, tender and sometimes irritable until the age of 3. Rubbing sore gums gently with a clean finger, the back of a cold spoon or a cold, wet cloth helps soothe the gums. Teething rings work well, but avoid teething biscuits—they contain sugar that is not good for baby teeth. The remainder of the 20 primary teeth typically erupt by age 3, but the place and order can vary.

While your baby is teething, it is important to monitor the teeth for signs of early childhood decay. Examine the teeth, especially on the inside or the tongue side, every two weeks for dull spots (whiter than the tooth surface) or lines. A bottle containing anything other than water and left in an infant’s mouth while sleeping can cause decay. This happens because sugar in the liquid mixes with bacteria in dental plaque, forming acids that attack the tooth enamel. Each time a child drinks liquids containing sugar (including milk and juice), acids attack the teeth for about 20 minutes. When awake, saliva carries away the liquid. During sleep, the saliva flow significantly decreases and liquids pool around the child’s teeth for long periods, covering the teeth in acids.
