So don't be too concerned if your child's teeth don't follow the pattern above. The eruption sequence can vary quite a bit from child to child. This leaves room for the larger permanent teeth to erupt. There is normally a space between all the baby teeth. Often, about 1 tooth comes in per month once the teeth start coming in. The teeth on the upper jaw often erupt 1 to 2 months after the same tooth on the lower jaw. Often, after the child reaches 2 years old, the 4 second molars (the last of the baby teeth) appear. Then the cuspids, or the pointed teeth, appear. Lateral incisors are beside (lateral to) the central incisors. This is followed by the first 4 molars, and the remaining bottom 2 lateral incisors. Next, the 4 upper incisors usually come in. This is followed by the second central incisor on the lower jaw. The first tooth to come in is usually a middle front tooth on the lower jaw. The following are general guidelines for the eruption of the baby teeth: Girls tend to have their teeth come in before boys. Most of the primary teeth will come in by 33 months.

The mother's diet should have adequate amounts of calcium, phosphorus, vitamin C, and vitamin D. Good nutrition from the mother during pregnancy is important in tooth development.
Teeth start developing in the unborn baby.
Anatomy and Development of the Mouth and Teeth Mandelbrot set images may be created by sampling the complex numbers and testing, for each sample point c.
The "style" of this repeating detail depends on the region of the set being examined. Images of the Mandelbrot set exhibit an elaborate and infinitely complicated boundary that reveals progressively ever-finer recursive detail at increasing magnifications, making the boundary of the Mandelbrot set a fractal curve.
