Start Early for Healthy Baby Teeth
The emergence of primary teeth, also called deciduous or baby teeth, generally follows a similar pattern in most children. The development of a complete set of these teeth begins beneath the gums around the fourth month of pregnancy. This underscores the importance of a nutritious prenatal diet for the baby's developing teeth, gums, and bones.
Typically, the first primary tooth will appear through the gums between six months and one year of age. By the age of three, most children will have a full set of twenty primary teeth. The American Dental Association (ADA) encourages parents to schedule a "well-baby" appointment with a pediatric dentist about six months after the first tooth emerges. Pediatric dentists educate parents and children on preventative strategies, emphasizing the importance of a gentle and consistent daily home care routine.
Even though baby teeth are eventually replaced, they are crucial for speech development, proper jaw growth, establishing good chewing habits, and guiding the correct spacing and alignment of permanent teeth. Proper care of primary teeth helps protect against painful tooth decay, premature tooth loss, malnutrition, and childhood gum disease.
The Typical Order of Primary Tooth Eruption:
Generally, the first teeth to appear are the central incisors (the very front teeth) on both the lower and upper jaws, typically between 6 and 12 months. These teeth (and all other primary teeth) can be gently cleaned with a soft, clean cloth to minimize the risk of bacterial infection. The central incisors are also usually the first to be lost, typically between 6 and 7 years of age.
Next, the lateral incisors (the teeth immediately next to the central incisors) appear on the upper and lower jaws, usually between 9 and 16 months. These teeth are typically the next to be lost, usually between 7 and 8 years of age. First molars, the larger, flatter teeth located towards the back of the mouth, then appear on the upper and lower jaws, usually between 13 and 19 months. The eruption of molars can sometimes be uncomfortable. Clean fingers, cool cloths, and teething rings can help soothe discomfort and soreness. First molars are generally lost between 9 and 11 years of age.
Canine (cuspid) teeth then typically appear on the upper and lower jaws, usually between 16 and 23 months. Canine teeth are located next to the lateral incisors and are usually lost during preadolescence, between 10 and 12 years old. Finally, the second molars complete the primary set on both the lower and upper jaws, usually between 23 and 33 months. Second molars are located at the very back of the mouth and are usually lost between the ages of 10 and 12 years old.
Other Interesting Facts About Primary Teeth:
- Lower primary teeth typically emerge before their corresponding upper teeth.
- Primary teeth often emerge in pairs, meaning there might be periods with no new teeth and then periods where two or more appear simultaneously
- Due to smaller jaw size, primary teeth are smaller than permanent teeth and often appear to have a whiter shade.
- It's common for school-aged children to have a mix of both primary and permanent teeth.
