Teething

The process of teething is sometimes referred to as "cutting teeth". It can take up to several years for all 20 deciduous (aka "baby" or "milk") teeth to emerge. The typical time frame for new teeth to appear is somewhere between six and nine months. Occasionally a baby may even have one or more teeth at birth. Teething may start as early as three months or as late, in some cases, as twelve months. Teething is the process by which an infant's teeth sequentially appear by breaking through the gums.
