In brief
Canadian dental guidance recommends a child's first dental visit within six months of the first tooth appearing, or by the first birthday — whichever comes first. That is earlier than many parents expect, and deliberately so: early childhood cavities can begin as soon as teeth erupt, and the first visit is less about treatment than about prevention, establishing comfort with the dental office and giving parents practical guidance while problems are still avoidable.
Key takeaways
- First visit: within six months of the first tooth, or by age one.
- Baby teeth matter — decay in them causes pain, infection and problems for adult teeth.
- Early visits build familiarity before any treatment is ever needed, reducing fear.
- The first appointment is short, gentle and largely educational for parents.
Why so early?
Because cavities start early. Tooth decay is one of the most common chronic childhood conditions, and it can affect infants — particularly with frequent night feeding, bottles at bedtime or constant sipping of anything but water. By the time decay is visible to a parent, it is often advanced.
Because baby teeth are not disposable. Primary teeth hold space for adult teeth, guide jaw development, and are essential for chewing and speech. Decayed baby teeth cause genuine pain and infection, and losing them early can crowd or misalign the adult teeth that follow.
Because familiarity beats fear. A child whose first dental memories are a gentle look, a ride in the chair and a sticker approaches later visits calmly. A child whose first visit happens at age four because something already hurts starts from a much harder place. Early visits are an investment in a lifetime of low-stress children’s dentistry.
What the first visit looks like
The first appointment is short and low-key. The dentist examines the teeth, gums, jaws and bite — often with the child on a parent’s lap in a knee-to-knee position for infants — checks for early signs of decay, and looks at development. Most of the visit is conversation with the parent: teething, cleaning techniques for tiny teeth, fluoride guidance appropriate to your child, feeding and bottle habits, soothers and thumb-sucking, and what to do if a tooth is injured. A fuller picture of routine visits as children grow is in what happens during a child’s dental checkup.
If your family is joining a new office, the new patient process typically includes health history and records — worth arriving a few minutes early to complete.
Setting the visit up for success
Timing helps: book for a time of day when your child is rested and fed, not nap time. Language helps too — calm, brief and positive, without loaded words like “hurt,” “needle” or “drill,” and without elaborate reassurance that signals something scary is coming. Practical preparation strategies are covered in how to prepare your child for a dental visit.
Building the habit from there
After the first visit, children generally follow a regular checkup schedule — commonly every six months, adjusted to the child’s risk. Between visits, the daily work belongs to parents: brushing twice a day with an appropriate amount of fluoride toothpaste, limiting sugary drinks and snacks, and never sending a bottle of milk or juice to bed. The full prevention playbook is in how can parents help prevent cavities in children.
When to contact a dentist
If your child’s first tooth has arrived — or the first birthday has — it is time to book. And do not wait for the milestone if you notice white or brown spots on the teeth, sensitivity, or an injury from a fall: those warrant a visit at any age.
Frequently asked questions
Isn't age one too young to sit in a dental chair?
Infants usually are not in the chair alone — the exam often happens with the child on a parent's lap. The visit is designed around what a one-year-old can tolerate: brief, gentle and mostly observational.
My toddler is two and has never seen a dentist. Is it too late?
Not at all — the best time is now. The dentist will examine for early decay and help you establish habits going forward. Starting late is far better than waiting for a problem.
What if my child cries the whole time?
Crying is common and expected at early visits; dental teams that see children are entirely used to it. A tearful first visit still accomplishes its purpose, and most children settle dramatically over subsequent visits.
Do baby teeth really need fixing if they fall out anyway?
Yes. Some baby molars remain until age eleven or twelve. Untreated decay in them causes pain and infection, and early loss can create alignment problems for the permanent teeth.
