Dental Eruption in Children

Dental eruption is the process through which teeth emerge through the gums. The first teeth that erupt in babies, commonly referred to as baby teeth, are already formed beneath the gums even before birth.

The age of dental eruption varies from child to child. Generally, the first teeth start to erupt when the child is around six to nine months old. The complete set of teeth typically erupts by the age of three. The formation of tooth roots is a process that is usually not completed until three to five years after the eruption of the tooth crown.

Typically, dental eruption occurs earlier in girls than in boys, and baby teeth are smaller and whiter than permanent teeth.

What are the symptoms of dental eruption in children?

When the time at which the eruption process of temporary teeth is approaching, young children can exhibit a series of manifestations, such as:

  • fever
  • irritability
  • red and painful gums
  • lack of appetite
  • moderate salivation
  • minor bleeding when the tooth erupts
  • redness on the cheek where the tooth erupts
  • restlessness during sleep

These symptoms are commonly seen in young children, but if they become severe, it is advisable to consult with a pediatrician and a pediatric dentist to guide and prescribe appropriate treatment for the child, either medication-based or using topically applied analgesics. Additionally, teething rings can provide temporary relief from the pain caused by dental eruption.

What is the order in which baby teeth erupt?

Dental eruption is a process that varies from baby to baby, and the order in which baby teeth erupt is presented below.

  • Upper and lower central incisors: age 6 to 12 months (sometimes upper central incisors erupt after the lower ones).
  • Upper and lower lateral incisors: age 7 to 16 months.
  • Upper and lower canines: Age 16 to 23 months.
  • First upper and lower molars: age 13 to 19 months.
  • The other two upper and lower molars: age 20 to 33 months.

Dental Eruption and Breastfeeding

During breastfeeding, the tongue covers the lower teeth, making it almost impossible for the baby to feed and bite at the same time. Babies bite for various reasons, which vary depending on the child’s age. A newborn may clench or, if there is a tooth, simply bite in response to a change in position or an attempt to slow down the milk flow if it is too fast.

Biting becomes more common when babies are teething, but it is usually a short-term issue and requires perseverance from the mother to find a solution. Each baby is different, and the solution depends on the baby’s age and temperament. Many mothers facing this issue find that a teething toy or feeding in a different position can be helpful.

When Do Baby Teeth Fall Out?

A child should start losing their baby teeth between six and seven years old. However, it is essential to properly care for baby teeth and treat them in case of cavities or infections, as they contribute to the proper growth and health of permanent teeth. Primary teeth give the child a normal facial appearance, assist in speech, and enable them to enjoy a varied and balanced diet.
