How old does a baby have to be to start teething? i have a two month old & he drools a lot! sometimes he cries out of no where, could it be his teeth?

Yes: Teething can cause discomfort and drooling in infants. Itcan also spike a slight fever. Best to check with your pediatrician.

At any time: Some babies are even born with teeth (natal teeth) or get them shortly after birth (neonatal teeth). Two months of age is early but not a concern. Typically children that get their first tooth early will also loose their baby teeth earlier than average. When kids loose a tooth in kindergarten it is a status symbol! if the teeth emerge in the appropriate sequence, early or late, it is insignificant.

It's possible: It's possible that an infant at 2 months is in the early phases of teething. Keep in mind that it is very common for infants to drool and cry. Most infants start teething around 6 months of age, so 2 month is a bit early, but not impossible.

Possibly: Most children start teething between 3-6 months of age, but there is a lot of normal variation. Some babies are actually born with bottom front teeth, others don't get them until 9 months old. This is all normal and there is nothing we can do to speed up or slow down the process.

Quite possibly: The traditional dental charts are out the window now as our children develop younger and younger these days. You can always rub your child's gums to see if there is any swelling, pain associated. Consult with your pediatrician if your are uncertain. Hope this helps.
