Primary teeth, also known as “baby teeth” or “deciduous teeth,” begin to develop beneath the gums during the second trimester of pregnancy.  Teeth begin to emerge above the gums approximately six months to one year after birth. Typically, preschool children have a complete set of 20 baby teeth – including four molars on each arch.One of the most common misconceptions about primary teeth is that they are irrelevant to the child’s future oral health.  However, their importance is emphasized by the Indian Society for Paediatric & Preventive Dentistry (ISPPD), which urges parents to schedule a “baby checkup” with a paediatric dentist within six months of the first tooth emerges. What are the functions of primary teeth? Primary teeth can be painful to acquire. To soothe tender gums, biting on chewing rings, wet gauze pads, and clean fingers can be helpful. Though most three-year-old children have a complete set of primary teeth, eruption happens gradually – usually starting at the front of the mouth.

The major functions of primary teeth are described below:

Speech production and development – Learning to speak clearly is crucial for cognitive, social, and emotional development.  The proper positioning of primary teeth facilitates correct syllable pronunciation and prevents the tongue from straying during speech formation.

Eating and nutrition –Children with malformed or severely decayed primary teeth are more likely to experience dietary deficiencies, malnourishment, and to be underweight. Proper chewing motions are acquired over time and with extensive practice.  Healthy primary teeth promote good chewing habits and facilitate nutritious eating.

Self-confidence – Even very young children can be quick to point out ugly teeth and crooked smiles.  Taking good care of primary teeth can make social interactions more pleasant, reduce the risk of bad breath, and promote confident smiles and positive social interactions.

Straighter smiles – One of the major functions of primary teeth is to hold an appropriate amount of space for developing adult teeth. In addition, these spacers facilitate the proper alignment of adult teeth and also promote jaw development. Left untreated, missing primary teeth cause the remaining teeth to “shift” and fill spaces improperly. For this reason, paediatric dentists often recommend space-maintaining devices.

Excellent oral health – Badly decayed primary teeth can promote the onset of childhood periodontal disease.  As a result of this condition, oral bacteria invade and erode gums, ligaments, and eventually bone.  If left untreated, primary teeth can drop out completely – causing health and spacing problems for emerging permanent teeth.  To avoid periodontal disease, children should practice an adult-guided oral care routine each day, and infant gums should be rubbed gently with a clean, damp cloth after meals. It’s important to care for your baby’s teeth from the start. 

Here's what to do: 

Begin cleaning your baby’s mouth during the first few days after birth by wiping  the gums with a clean, moist gauze pad or washcloth. As soon as teeth appear, decay can occur. A baby’s front four teeth usually push through the gums at about 6 months of age, although some children don’t have their  first tooth until 12 or 14 months. For children younger than 3 years, start brushing their teeth as soon as they begin to come into the mouth by using fluoride toothpaste in an amount no  more than a smear or the size of a grain of rice. Brush teeth thoroughly  twice per day (morning and night) or as directed by your kids paediatric dentist. Supervise children’s brushing to ensure that they use of the  appropriate amount of toothpaste. For  children 3 to 6 years of age, use a pea-sized amount of fluoride  toothpaste. Brush teeth thoroughly twice per day (morning and night). Supervise children’s brushing and remind them not to swallow the toothpaste. Until  you’re comfortable that your child can brush on his or her own, continue to brush your child's teeth twice a day with a child-size toothbrush and a  pea-sized amount of fluoride toothpaste. When your child has two teeth that touch, you should begin flossing their teeth daily.

Paediatric dentists who specialize in kids dentistry would advice you about various preventive treatment options like Fluoride application, preventive resins and sealants along with regular dental check-ups and proper brushing demonstration and monitoring to prevent the development of dental problems in your kids.
