Deciduous teeth otherwise known as milk teeth, baby teeth, temporary teeth and now more commonly primary teeth are the first set of teeth in the growth and development of humans. There are 20 deciduous teeth that appear in the mouth of a child and stay there for some years before falling and leaving their place to 32 permanent teeth.

The chronological development of the deciduous teeth are:

  • 6th month core areas mandibular

  • 10th month core areas maxillary

  • 11th month maxillary lateral incisors

  • 13th month mandibular lateral incisors

  • 16th month first molars maxilla and mandible

  • 19th month fangs upper and lower jaw

  • 27th month of the second mandibular molars

  • 30th month maxillary second molars

The chronological development of permanent teeth is :

  • 6th-7th time center field mandibular first molar maxillary first molar mandibular

  • 7th-8th time center field maxillary lateral mandibular area

  • 8th-9th time Oblique sector maxillary

  • 10th-11th years maxillary first premolar

  • 10th-12th year canine mandibular first premolar mandibular second premolar maxillary

  • 11th-12th time bicuspid maxillary second premolar mandibular

  • 12th-13th year second molar maxillary second molar mandibular

  • 17th to 21st year maxillary third molar, mandibular third molar

Indications export deciduous teeth:

  1. Deciduous teeth damaged whose treatment and rehabilitation are not feasible

  2. Cases of acute alveolar abscess

  3. Cases of fractures of the roots after injury

  4. Prolonged stay of a deciduous tooth 5. Inhibition permanent tooth eruption


Preventive fillings or Sealants is a method used to combat decay of the teeth. In particular, we cover the occlusal surface of a tooth with a special composite resin to protect certain teeth which are susceptible to decay Applies to :

  • children 6-8 years to protect their first permanent molars

  • in cases of back teeth with deep grooves

  • people with disabilities who cannot apply proper oral hygiene

  • in some cases incipient caries

The whole process is completely painless, requires short time and does not need any grinding of the tooth The lifecycle of a filling is up to five years and definitely need retesting once a year to verify the condition


Fluoride helps to increase resistance of teeth to decay and is used to prevent and reduce tooth decay in children's teeth by the dentist Other sources of fluoride intake are:

  • Through drinking water

  • Through salt

  • Through milk

  • Through the sugar

  • Through the toothpaste with fluoride

  • Through mouthwashes containing fluorine

  • Through special tablets or drops etc.

Fluoridation is indicated immediately after the first permanent tooth has appeared in the jaw, that is at the age of 6-15 years The process is very simple, painless and harmless. We use sterile plastic trays with a special fluoride gel for the upper and lower jaw, respectively, for 1 minute.
