I believe I read babies first tooth can come anytime between 3 months and 1 year- most typical age is 7 months. My daughter started at about 4 mos though so there really is no exact time. Obvious signs are drooling, gumming everything, low fever, crankiness, and trouble eating (because sucking puts pressure on sore gums). You can give baby Tylenol (check with your doc for dosage), teething toys (like the gel rings you can put into the fridge to get cold) or a wet washcloth put into the freezer for a few minutes for baby to chew on. Also putting your finger in babies mouth and putting slight pressure against the incoming tooth can give relief and usually doesn't hurt your finger too bad. My ped advised against Orajel because it can numb other parts of the mouth and cause a choking hazard. He said the only real relief to the gums comes from counter pressure from your finger or baby biting on something. Good luck.
