Your child’s smile changes quickly in the early years. One day you are celebrating that very first tiny tooth, and before you know it, they are heading off to kindergarten with a full set of baby teeth and a growing sense of independence. As parents, it can be hard to know exactly what to expect at each stage or when certain dental milestones should happen. Having a general timeline in mind makes it easier to feel confident about your child’s oral health from infancy through the early school years.
At Elgin Dental Group, we often remind families that dental care starts earlier than many people realize. Baby teeth may be small, but they play a big role in chewing, speech development, and guiding permanent teeth into place. Building healthy habits from the beginning helps set the foundation for strong, confident smiles as your child grows.
Infancy to Toddler Years: Building Healthy Habits Early
Most babies get their first tooth around six months of age, although it can happen earlier or later. As soon as that first tooth appears, it is time to begin gentle cleaning. Using a soft infant toothbrush and a tiny smear of fluoride toothpaste, about the size of a grain of rice, helps remove plaque and protect enamel. Even before teeth erupt, wiping your baby’s gums with a clean, damp cloth after feedings can help keep their mouth clean.
One of the most important milestones during this stage is the first dental visit. We recommend scheduling your child’s first appointment by their first birthday or within six months of the first tooth appearing. Early visits are typically short and positive. They allow us to check development, look for early signs of decay, and answer any questions about teething, thumb sucking, or feeding habits. These early appointments also help children become comfortable in the dental environment.
As toddlers grow, brushing twice a day becomes part of the daily routine. At this stage, parents still need to do most of the brushing. Children often want to help, which is wonderful, but they do not yet have the coordination to clean thoroughly on their own. Avoiding prolonged exposure to sugary drinks and limiting bedtime bottles with milk or juice also reduces the risk of early childhood cavities.
Preschool Years: Protecting and Monitoring Baby Teeth
By age three, most children have a full set of twenty baby teeth. This is an important time to reinforce brushing habits and introduce flossing when teeth begin to touch. A pea-sized amount of fluoride toothpaste is appropriate at this age, and parents should continue supervising brushing to ensure all surfaces are cleaned properly.
During the preschool years, cavities can develop quickly if plaque is not removed consistently. Regular dental check-ups allow us to monitor for early signs of decay and provide professional cleanings that remove buildup in hard-to-reach areas. These visits also give us the opportunity to offer guidance on diet. Sticky snacks, frequent grazing, and sugary treats can all increase the risk of cavities, so balanced meals and water between snacks make a big difference.
This is also the stage when we watch for habits that may affect oral development, such as thumb sucking or prolonged pacifier use. Most children naturally outgrow these habits, but if they continue beyond age four, we may discuss gentle strategies to help prevent changes in bite alignment. Our goal is always to support development while keeping the experience positive and reassuring for both child and parent.

Kindergarten to First Grade: Preparing for Permanent Teeth
Around age six, children begin an exciting transition as their first permanent teeth start to appear. The lower front teeth are usually the first to erupt, followed closely by the first permanent molars at the back of the mouth. These molars often come in quietly, without replacing baby teeth, so parents may not even notice them at first. Because they are brand new and have deep grooves, they are especially vulnerable to cavities.
At this stage, brushing technique becomes even more important. Children can begin taking on more responsibility, but parents should still supervise and assist to ensure thorough cleaning. Encouraging brushing for a full two minutes, twice a day, and flossing daily helps protect both baby and permanent teeth. Fluoride continues to play an important role in strengthening enamel and reducing the risk of decay.
We may also discuss dental sealants once permanent molars have fully erupted. Sealants provide a protective coating over the chewing surfaces, helping prevent cavities in areas that are difficult to clean. Combined with regular check-ups and professional cleanings, they are an effective way to protect growing smiles during the early school years.
As children approach first grade, they are becoming more independent, but they still need guidance and encouragement. Consistency is key. Regular dental visits allow us to monitor alignment, check for early orthodontic concerns, and ensure that both baby and permanent teeth remain healthy throughout this important transition.
