Tooth Eruption

Eruption of the teeth is the process when a tooth goes through the gum and becomes visible in the mouth.

Primary teeth

The following table shows when the primary teeth (baby teeth) erupt. It is important to note that the eruption time varies from one child to another.

Primary Teeth
Upper Teeth	Eruption Time	Age of Loss of Tooth
Central Incisor	8 to 12 months	6 to 7 years old
Lateral Incisor	9 to 13 months	7 to 8 years old
Cuspid	16 to 22 months	10 to 12 years old
First Molar	13 to 19 months	9 to 11 years old
Second Molar	25 to 33 months	10 to 12 years old
Lower Teeth	Eruption Time	Age of Loss of Tooth
Central Incisor	6 to 10 months	6 to 7 years old
Lateral Incisor	10 to 16 months	7 to 8 years old
Cuspid	17 to 23 months	9 to 12 years old
First Molar	14 to 18 months	9 to 11 years old

Some facts to consider

• Generally, tooth eruption occurs earlier for girls than for boys.
• Teeth erupt two by two, one on each side.
• Primary teeth are smaller and whiter than permanent teeth.
• Around the ages of two to three years old, primary teeth should all have erupted.

Signs and symptoms

There are signs and symptoms that can help recognize the eruption of teeth for babies:

• Irritation of the mouth.
• The baby placing objects or fingers in the mouth and biting on them.
• An increase of saliva in the mouth.
• Loss of appetite.
• Inflamed gums.
• General agitation.
• Redness on the cheek near the area where a tooth is erupting.

The tooth eruption process should not cause fever, vomiting, or diarrhoea. If these problems appear, it is important to consult a doctor.

To relieve the pain during tooth eruption:

• Use a clean finger to massage the gum.
• Use an anaesthetic cream sold in pharmacies (such as Orajel).
• Allow the baby to suck on a clean cloth moistened with cold water.
