The importance of primary teeth and the eruption pattern of teeth

Primary teeth are very important for the following reasons:

  • They help in proper chewing
  • They aid in good pronunciation and speech habits
  • They encourage normal development of the jaw bones and muscles
  • They ensure that there is enough room for permanent teeth to erupt
  • They help your child feel comfortable with the way he/she looks
  • They guide the permanent teeth to erupt at the correct position in the dental arch since the permanent teeth grow under the primary teeth

If a primary tooth is lost too early, the teeth beside it will drift to fill in the empty space and create a lack of space in the jaw for the permanent successor tooth. Consequently, the permanent tooth may erupt either in the wrong position or may not erupt at all and may remain impacted in the gums. Crowded teeth negatively affect the oral hygiene of your child and require orthodontic treatment for their proper arrangement in the mouth. Impacted teeth require surgical intervention in the gums to expose them. Although the best space maintainer for permanent teeth are primary teeth, in cases where primary teeth are lost too early, a perfect substitute of such teeth is an orthodontic appliance called space maintainer.
