Your baby should see a dentist by their first tooth or first birthday, whichever comes first. The American Academy of Pediatric Dentistry recommends a visit by age one. Early visits are short and gentle, and they focus on prevention, feeding habits and helping your child feel comfortable.
A dental visit for someone who still naps twice a day can sound early. Many parents wonder what there is to check when a baby has only a few teeth, or none showing yet. In practice, that first appointment is less about treatment and more about setting your child up well. Below we explain why the timing matters, what actually happens at an infant visit, how to care for those first teeth at home, and how to make the day go smoothly.
Baby teeth start forming before birth, and the first ones usually break through around six months of age. From the moment a tooth appears, it can develop a cavity. Early childhood decay can move quickly in thin baby enamel, and it often starts in places parents cannot easily see, such as along the gumline or on the back of the upper front teeth.
An early visit gives a board-certified pediatric dentist the chance to look at your child's teeth and gums while everything is still simple. It is also the ideal time to talk about the habits that shape oral health for years: how often your baby feeds at night, what goes in the bottle or sippy cup, how and when to start brushing, and how fluoride fits in. Small adjustments now can prevent problems that are much harder to fix later.
There is a comfort benefit, too. Children who start visiting the dentist young tend to see it as a normal, friendly place. When a later visit involves more than a quick look, the office, the chair and the team are already familiar.
An infant visit is short and relaxed. Most of it happens with your baby sitting on your lap. Here is what it typically includes:
Some babies fuss or cry during the exam, and that is completely normal. It does not mean the visit went badly. The exam is quick, and crying even makes it easier for the dentist to see inside the mouth.
Our office offers a free first visit for children under 3, so there is no cost to getting started. You can read more about how we care for our youngest patients on our infant dentistry page.
Good habits can start before the first tooth appears. Wipe your baby's gums with a clean, damp cloth after feedings. This removes milk and gets your baby used to having their mouth cleaned.
Once a tooth appears, brush twice a day with a soft infant toothbrush and a smear of fluoride toothpaste about the size of a grain of rice. That tiny amount is enough to protect the enamel while keeping the amount your baby swallows low. As more teeth come in and touch each other, gently cleaning between them becomes part of the routine as well.
Brushing a squirmy baby is not always easy. Many parents find it easiest to sit on the floor with the baby lying back in their lap, the same position as the knee-to-knee exam. Keep it quick, use a calm voice and try to brush at the same times each day so it becomes routine.
They can. When a baby falls asleep with milk or formula in their mouth, the liquid pools around the teeth overnight. Saliva flow slows during sleep, so that milk sits on the enamel for hours and can lead to early childhood cavities, sometimes called baby bottle tooth decay.
A few simple habits lower the risk. Avoid putting your baby to bed with a bottle. If your baby feeds during the night, wipe their teeth after the last feeding. Save juice and sweetened drinks for rare occasions, if at all, and offer water between meals once your pediatrician says it is appropriate.
Feeding questions are a normal part of an infant visit, and there is no judgment involved. Every family's routine looks different, and the goal is simply to find small changes that fit yours. If your baby has trouble latching or feeding, our post on tongue-tie and lip-tie in kids explains when a tight frenum can be part of the problem.
Timing makes a real difference with babies and toddlers. Book the appointment for a time of day when your child is usually rested and fed, rather than right before a nap. Bring a favorite toy or blanket, and keep your own tone relaxed and upbeat, since young children pick up on how their parents feel.
It also helps to jot down your questions ahead of time. Parents often want to ask about teething, pacifiers, thumb sucking, sippy cups, toothpaste or a spot on a tooth they noticed. Writing them down means you will not forget anything once you are in the chair with a wiggly baby on your lap. If thumb sucking is on your list, our post on when thumb sucking becomes a concern is a good place to start.
Most babies get their lower front teeth first, around six months of age. The rest follow gradually, and most children have the full set of 20 baby teeth by about age three. There is wide variation, though. Some babies get a first tooth earlier, and others not until after their first birthday. Both can be perfectly normal, and we track how the teeth are coming in at each visit.
Teething can bring drooling, chewing on everything in sight and some fussiness. A clean, chilled teething ring or gently rubbing the gums with a clean finger can help. If you are unsure whether symptoms are from teething or something else, ask your pediatrician or bring it up at your baby's dental visit.
Usually not. Infant visits are mostly a visual exam. X-rays are taken only when needed, such as to see between teeth or check developing adult teeth as your child gets older.
Most children do well with a visit every six months. Kids at higher risk for cavities may need visits every three to four months, and we will let you know if that applies. Our pediatric cleanings and exams page explains what those routine visits include.
Yes, at the doses we use. Fluoride varnish is painted on in a tiny, controlled amount in under a minute and sets on contact with saliva. It strengthens enamel and can reverse the earliest stages of decay.
Yes. For babies, you are part of the exam. For older children, parents are welcome to stay alongside, and we explain each step to your child before we do it.
If your baby has a first tooth or a first birthday coming up, it is a great time to start. Our pediatric dentists keep infant visits short, gentle and focused on answering your questions. Contact our San Marcos office to book your baby's free first visit, or call us at (760) 599-5437.
