When should parents begin brushing their child's teeth?

The correct choice is to begin brushing a child's teeth as soon as the first tooth appears. This practice is important because even a single tooth can be susceptible to decay, and early oral hygiene habits help establish a foundation for a lifetime of good dental health. Starting to brush teeth at this early stage also familiarizes the child with dental care, setting the stage for easier brushing as they grow older.

Additionally, this approach reinforces the importance of maintaining oral hygiene from a young age, which is crucial in fighting cavities and developing a routine that the child will carry into adulthood. Parents should use a soft-bristled toothbrush and a small smear of fluoride toothpaste to safely clean their child's teeth, ensuring that they take care of their oral health from the onset of tooth eruption. Establishing this routine early can contribute significantly to preventing dental problems later in life.
