Tooth eruption

The first tooth can come in as early as 4 months and as late as 12 months. Children may have some symptoms (irritability, drooling, and/or loss of appetite) but it should not make them sick or cause a fever. If he/she develops a fever, check with your doctor. If he/she has some discomfort, avoid using teething gels. Instead, many babies like a clean teething ring, cool spoon or cold wet washcloth while others simply like the rubbing of their parents' clean finger. Do not give him/her teething biscuits since most of them contain sugars. Don't forget to wipe or brush his/her teeth as soon as they come in!

As for permanent teeth, children rarely have any symptoms when they start coming in except maybe a little sensitivity, especially when chewing.

There is a lot of variability in children for the timing of eruption of different teeth. The diagram below is a good indication of the timing of eruption of primary and permanent teeth..
