hi...normal timing, when the baby first start having teeth eruption is 6 to 7 months. But in a few cases it may be delayed by another 6 or 7 months for some local reasons. As your baby is now almost 14 month old, teeth must be on their way in oral cavity by maximum of next one or two months. you can feel them by rubbing against the gums of the teeth, which appers swollen and with slighted elevation of crown portion, that can be felt.
the reason for teeth coming late are largely because of firm gingivae (soft tissue
overlying teeth). the other rare causes may hormonal
disturbances/ metabolic disturbances, lack of teeth and sometimes systemic problems/ or cleft lip and palate
patients, down syndrome, ectodermal dysplasia
to name a just few.
Also, Kindly pay attention on skin/ nails and hair of the baby. if they are normal, there is little to be worried about.
if still it doen't happen, ask for a dentist
opinion, who can perform a xray of jaws and can make sure presence of the teeth
