Watching your baby’s first tooth appear is an exciting milestone, but it also marks the beginning of an important stage in their oral health journey. Every child develops at their own pace, yet understanding the typical baby teeth growth timeline can help parents know what to expect and recognize when it’s time to ask questions during a dental visit.
At Great Grins, we enjoy partnering with families from infancy through childhood, providing guidance that supports healthy smiles from the very beginning. Whether your baby is just starting to drool or already has a mouth full of tiny teeth, knowing what comes next can help you care for their developing smile with confidence.

Birth to 3 Months: Building the Foundation
Although no teeth are visible yet, your baby’s primary teeth are already developing beneath the gums. During these early months, parents can begin establishing healthy oral care habits by gently wiping their baby’s gums with a clean, damp washcloth or a soft infant gum cleaner after feedings.
This simple routine removes bacteria, gets your baby accustomed to oral care, and creates healthy habits long before the first tooth erupts.
Around 4 to 7 Months: The First Tooth Appears
Most babies begin teething between four and seven months of age, although some may start earlier or later. The lower central front teeth are usually the first to emerge, followed closely by the upper front teeth.
During this stage, babies often experience increased drooling, swollen or tender gums, a desire to chew on objects, mild fussiness, and occasional changes in sleeping or eating habits. These symptoms are generally temporary and improve as the tooth breaks through the gums.
Parents can safely soothe discomfort by offering chilled (not frozen) teething rings, gently massaging the gums with a clean finger, or using a cool, damp washcloth for babies to chew on. If discomfort seems significant, consult your pediatrician or pediatric dentist before using pain-relieving medications.
8 to 12 Months: More Front Teeth Emerge
As babies approach their first birthday, additional front teeth typically appear. By this point, many infants have four to eight teeth that help them begin exploring new foods and developing chewing skills.
Once the first tooth erupts, it’s time to start brushing with a soft-bristled infant toothbrush. Use only a tiny smear of fluoride toothpaste about the size of a grain of rice. Gentle brushing twice each day helps prevent plaque buildup and establishes an important lifelong routine.
Parents should also avoid putting babies to bed with bottles containing milk, formula, or juice, as prolonged exposure to sugars can contribute to early childhood cavities.
12 to 18 Months: Expanding the Smile
During the second year of life, the first molars often begin to erupt. These larger teeth are essential for chewing and preparing children for a wider variety of healthy foods.
Molars can sometimes cause more noticeable discomfort because of their larger size. Increased drooling, gum tenderness, and chewing behavior are common during this period. Fortunately, the same soothing techniques used for earlier teeth generally remain effective.
As more teeth come together, parents should begin gently flossing between teeth that touch. Although this may seem early, flossing removes food particles and plaque from areas that toothbrushes cannot reach.
18 to 24 Months: Canines Begin to Appear
The canine teeth, sometimes called cuspids, usually emerge between the front teeth and molars during this stage. These pointed teeth help children bite and tear food more effectively.
By now, toddlers are becoming more independent and may want to participate in brushing. Parents should encourage this enthusiasm while continuing to provide hands-on assistance. Young children typically lack the coordination to brush thoroughly on their own.
Making brushing enjoyable through songs, colorful toothbrushes, or simple games can encourage positive habits that continue as children grow.
Ages 2 to 3 Years: A Complete Set of Baby Teeth
By the age of three, most children have all 20 primary teeth. At this stage, brushing twice daily, flossing regularly, maintaining healthy eating habits, and attending routine dental visits become even more important.
A complete set of healthy baby teeth supports speech development, proper chewing, facial growth, and the spacing needed for permanent teeth. Protecting these teeth helps establish a strong foundation for lifelong oral health.
Families looking for guidance from a pediatric dentist in Portland can benefit from regular preventive visits that monitor growth and identify concerns before they become more serious.
Every Child Develops at Their Own Pace
While the timeline above reflects average development, it’s important to remember that every child is different. Some babies cut their first tooth at four months, while others may not see one until after their first birthday. Genetics, overall development, and individual growth patterns all influence tooth eruption.
The order in which teeth appear may also vary slightly without indicating a problem. Pediatric dentists evaluate overall patterns rather than focusing on exact dates. If multiple teeth seem significantly delayed, erupt in unusual positions, or if parents have concerns about oral development, a dental evaluation can provide reassurance and guidance.
At Great Grins, we help parents understand what is normal while monitoring each child’s unique dental development throughout infancy and early childhood.
Building Healthy Habits from the Very Beginning
Healthy smiles begin long before all the baby teeth have arrived. Consistent oral hygiene, balanced nutrition, regular dental visits, and early education all contribute to strong, healthy teeth throughout childhood.
At Great Grins, we believe that early preventive care gives children the best possible start. Our team partners with families to monitor every stage of the baby teeth growth timeline, answer questions about teething, and provide personalized guidance as your child’s smile develops.
By understanding what to expect month by month and practicing good oral care from infancy, parents can help ensure their children enjoy healthy, confident smiles for years to come.
