Teething is when a baby's teeth begin to push through the gums. These teeth begin to appear as early as three months of age in humans, or as late as a year. It can take a few years for the entire first set of teeth to appear, though it is often complete within one or two years. Occasionally an infant will be born with one or more teeth already protruding from the gums, but this is no cause for alarm.
If teeth haven't showed up yet brushing and flossing isn't required. Even though they don't have teeth, you should still clean his/her gums with a damp cloth. Normally infants don't like this at first, but if you turn this routine into a habit he/she begins to get used to it.
There are some problems that can arise later with your baby teeth if you let your infant to fall asleep with a bottle. If the bottle contains milk formula or anything sugary, it forms around the teeth and mouth which could potentially cause cavities to form.
