Teething is the process by which an infant's teeth sequentially appear by breaking through the gums. Teething may start as early as three months or as late, in some cases, as twelve months. The typical time frame for new teeth to appear is somewhere between six and nine months. It can take up to several years for all 20 deciduous (aka "baby" or "milk") teeth to emerge. The process of teething is sometimes referred to as "cutting teeth".

Sequence of appearance

6.5 month infant with right lower central incisor about to emerge...

..5 days later that incisor is visible.

The infant teeth tend to emerge in pairs - first one lower incisor emerges then the other lower incisor emerges before the next set begin to emerge. The general pattern of emergence is:

1. Lower central incisors (2)
2. Upper central incisors (2)
3. Upper lateral incisors (2),
4. Lower lateral incisors (2)
5. First molars (4)
6. Canines (4)
7. Second molars (4)

Milk teeth tend to emerge sooner in females than in males. The exact pattern and initial starting times of teething appear to be hereditary^{[citation needed]}. When and how teeth appear in an infant has no bearing on the health of the child.

Signs of teething

Signs of teething may include:^{[citation needed]}

• Poor mood
• Loss of appetite
• Chewing of objects
• Bruises/swelling in gums
• Excess salivation
• Runny nose

Teething has not been shown to cause fever or diarrhea.^[1] A slight rise of temperature may occur when the teeth come through the gum^{[citation needed]}, but this does not make a baby ill.

Treatment

Infants chew on objects to aid in the teething process. This can be dangerous if the baby is allowed to chew on objects which are small enough to be swallowed or which could break while being chewed and cause choking. Teething rings and other toys, called teethers, are often designed with textures that will appeal to an infant during teething.

In cases where the infant is in obvious pain, some doctors recommend the use of anti-inflammatories or child-safe pain-relief treatments containing benzocaine. Some infants gain relief from chewing on cold objects.

Dentists recommend brushing infants' teeth as soon as they appear. It is not advisable to wait for the teething process to be complete. Dentists may recommend against the use of fluoride toothpaste during teething.
