Temporary dentition

Temporary dentition
The temporary dentition is formed of twenty teeth, ten upper and ten lower; these are called: central incisors, lateral incisors, canines, first molars and second molars. The first teeth begin to appear between the fourth and sixth months of life, and start to be replaced between 6 and 7 years of age, approximately. The principal differences with the permanent dentition include their size (the temporary teeth are smaller), color and resistance to caries (they are more bluish- weight and less resistant due to their lower level of calcification), and sensitivity, which is lower due to the smaller number of nerve terminals. Another difference is that separations between the teeth (diastema) are usually present in the temporary dentition due to the larger size that the new teeth will have (1)(6).
