In brief: Depends
I believe visual exam can tell a dentist if x- rays are needed in a child and if so how many.
Even though digital dental x rays are safe as part of routine check up, if they can be avoided why not? If we see dental cavities visually then we need to do x ray to determine depth of it. 4 to 8 x rays per year ( depending on how many teeth have erupted and child's age) is average.

In brief: Least is best
As few as necessary. Effects of x-rays are cumulative over time.

According to the ADA: Dental X-rays are a useful diagnostic tool when helping your dentist detect damage and disease not visible during a regular dental exam. How often X-rays should be taken depends on your present oral health, your age, your risk for disease, and any signs and symptoms of oral disease. For example, children may require X-rays more often than adults because their teeth and jaws are still developing and their teeth are more likely to be affected by tooth decay than those of adults. Your dentist will review your history, examine your mouth and then decide whether or not you need X-rays. Dental X-ray exams are safe; however, they do require very low levels of radiation exposure, which makes the risk of potentially harmful effects very small. Dental X-ray tools and techniques are designed to limit the body's exposure to radiation and every precaution is taken to ensure that radiation exposure is As Low As Reasonable Achievable (the ALARA principle). A leaded apron minimizes exposure to the abdomen and should be used when any dental radiograph is taken. Also, a leaded thyroid collar can protect the thyroid from radiation, and should also be used whenever possible. The use of a leaded thyroid collar is recommended for women of childbearing age, pregnant women and children.
