Normal Eruption of Teeth

The first teeth to appear in the mouth are usually the lower central incisors. They tend to erupt anywhere from six to twelve months of age. The rest of the baby teeth follow suit with the second molars coming in at around two years of age. After that, things are pretty constant until kindergarten. The permanent teeth tend to erupt at 6-7 years of age, however, a range of 5-8 years is still within the normal range. Just because your child has not lost their first baby tooth by their eighth birthday, would not be a cause of concern. However, if no teeth have been shed by age nine, it is best to consult a physician just to rule out any possible endocrine problems. The first permanent molars usually come in around six years of age, hence the name “six year molars”. The twelve year molars are the second molars, and the third molars are the wisdom teeth that usually erupt between 17 and 25 years of age.

Teething

Teething is when teeth are erupting through the gums and the symptoms associated with it. There are many myths on all of the maladies that teething will cause, most being totally untrue. Surely the teething infant can get a little fussy because the gums do  get sore, but it doesn’t cause fever, nasal congestion, diarrhea, etc. It is best to avoid all of the drug store teething preparations. Local anesthetics should not be used because they have too much difficulty with proper dosing. Too much benzocaine or lidocaine can cause seizures and in severe cases, death. The best thing to use for teething discomfort is a rubber teething ring that can be place in the refrigerator. It is thought that cool pressure placed over the gums can be soothing. In cases where an analgesic is needed, be certain to carefully follow the dosing instructions since infants are tiny and susceptible to overdosing.
