Can teething cause a fever?

Even though grandmothers may debate the findings, research has not shown a causal relationship between teething and development of a fever. Viral infections, which commonly occur independently simultaneous with dental eruptions, may product a fever. However, there is no teething virus.

Can teething cause vomiting?

The process of teething is not causally related to vomiting. As several pediatric dentists have noted, "Teething does not cause fever, runny nose, cough, or diarrhea. Teething causes teeth."

What is the order of tooth eruption in infants?

The following is the general order of eruption of primary teeth:

  • Central incisors: 6-12 months of age
  • Lateral incisors: 9-16 months of age
  • Canine teeth: 16-23 months of age
  • First molars: 13-19 months of age
  • Second molars: 22-24 months of age

Between 6 to 12 years of age, the roots of these 20 "baby" teeth degenerate, allowing their replacement with 32 permanent "adult" teeth. The third molars ("wisdom teeth") have no preceding "baby" version and generally erupt in mid to late adolescence. Because of their tendency to promote crowding and crooked orientation, they are often removed.

How long does teething last?

Children will commonly have variable discomfort during the few days before tooth eruption through the gum line. Some babies are bothered more than others during the migration through the tissues deep to the gum line. Because of their shape, molars are more likely to be associated with teething discomfort.
