Baby Teeth Eruption Chart
Although primary teeth begin their formation even before a baby is born, the initial baby tooth usually pierces through the gumline around 4 to 6 months of age. By the time a child reaches three years old, all twenty of their primary teeth should have completely emerged.

Even though baby teeth start developing before birth, parents often wonder when these tiny pearly whites will actually begin to fill out their child's smile. This overview offers insights into the typical eruption timeline for a baby's first teeth with our detailed baby teeth chart.

What to Expect During Teething?
Teething represents a significant developmental milestone for your little one, but it can also bring its share of difficulties. As primary, or deciduous, teeth start to push through the gums; your baby might experience discomfort and changes to their usual routine.
Here are some common signs you might observe when your baby is teething:
- Excessive Drooling: Babies tend to produce more saliva during teething. This can lead to a "drool rash" on their skin. It’s important to keep your little one’s sensitive skin clean and dry during this period.
- Increased Irritability: Fussiness and general grumpiness are common during teething as your baby copes with gum discomfort.
- Disrupted Sleep: With fewer distractions to alleviate their sore gums, teething infants often become more unsettled at night, leading to disturbed sleep patterns.
- Tender Gums: Teething gums often appear redder and swollen, and they can be quite sensitive to the touch.
- More Chewing: Your baby might attempt to chew on various objects as a way to find relief from the pressure in their gums.
How to Soothe a Teething Baby
Fortunately, there are several helpful strategies you can employ to comfort your little one during this phase:
- Gentle Massage: Use a clean finger to gently rub your baby's gums.
- Offer a Teether: A firm, chilled (but not frozen) teething ring with textured surfaces can provide soothing relief when your baby chews on it.
- Soft Brushing: Carefully clean and massage your baby's gums with an extra soft bristled baby toothbrush.
- Dietary Considerations: If your baby has already begun eating solid foods, cool, soft options may help provide comfort. For younger infants, focus on non‑feeding soothing methods such as chilled teethers or gentle gum massage.
- Consult a Professional: If needed, speak with your pediatric medical professional about potential over-the-counter pain relievers, like acetaminophen.
- Provide Distraction: Engaging your little one can work wonders! Try taking them to the park, reading an interesting book, or playing with their favorite toy to divert their attention from teething symptoms.
When to Start Brushing Baby Teeth?
It is advisable to begin brushing your baby’s teeth as soon as the first tooth emerges. Utilize an extra-soft bristled toothbrush to gently clean your baby's new teeth and sensitive gums.
The Crest Baby Training Toothpaste and Toothbrush Kit includes a manual toothbrush with extra-soft bristles for a gentle clean and mild strawberry flavored toothpaste free of artificial flavors, sodium lauryl sulfate, sweeteners, and dyes.
Caring for Baby's First Teeth
Maintaining baby, or deciduous, teeth is as vital as caring for permanent adult teeth, as they establish the foundation for lifelong oral health. Baby teeth are crucial for proper speech development, effective eating, and the correct formation of the jaw.
Follow these simple steps to care for your little one's emerging smile:
- Gently cleanse away plaque and bacteria from your baby’s gums after each feeding using a damp washcloth.
- Carefully clean your baby's gums and teeth with a baby toothbrush equipped with extra soft bristles.
- Schedule a visit with a pediatric dental professional as soon as the first baby tooth appears, or by the age of one. This ensures proper development of your child's teeth and jaw and allows for personalized recommendations to support their healthy smile.
When Do Adult Teeth Come In?
The first permanent molars typically begin to appear around age six.
At this stage, using a fluoridated toothpaste is essential for effective plaque removal and cavity prevention. The ADA-approved Crest Kids Advanced Color Changing Toothpaste, which shifts from blue to pink, encourages kids to brush for the dentist-recommended two minutes. Moreover, it offers superior protection for children from Kid’s Crest, which is the #1 kids’ toothpaste brand in America.
By the age of 13, most of your child's adult teeth, with the exception of third molars (wisdom teeth), should have fully erupted. Wisdom teeth are generally expected to emerge during the late teenage years or early twenties.

How to Floss Kids' Teeth
While brushing twice daily is crucial for a healthy mouth, flossing is equally important and should not be overlooked as part of your child’s daily oral hygiene. Begin flossing your baby’s teeth once any two teeth are touching each other.
Continue to floss your child's teeth for them until they are approximately eight years old and capable of mastering the correct technique independently.
Here’s how to properly floss your child’s teeth:
- Carefully slide the floss between two adjacent teeth.
- Form a "C" shape with the floss around each tooth.
- Gently move the floss up and down against the tooth surface.
- Floss beneath the gumline to dislodge trapped plaque and food debris.
- Use a fresh section of floss for each tooth.
- Have them rinse and spit after flossing to remove any loosened particles.
Teeth Brushing for Kids 6+
As children grow older, their desire for independence increases, and this extends to their daily toothbrushing routine. A key part of "big kid" brushing involves taking responsibility for their own oral hygiene, with minimal prompting from parents.
Encourage your child to take charge of their brushing habits with the following steps:
- Ensure they brush their teeth twice a day for the dentist-recommended two minutes during each session.
- Consider upgrading to an Oral-B Kids Electric Toothbrush for children ages 6 and up. These brushes are effective at removing plaque yet gentle on developing teeth, often featuring favorite characters for added motivation!
- Demonstrate to your child how to hold their toothbrush at a 45-degree angle to the gumline.
- Teach them to glide, rather than scrub, across their teeth, especially when using an electric toothbrush designed to do the work.
- Instruct them to gently brush all tooth surfaces, including the front, back, and chewing areas.
- Have your child brush for the full two minutes, guided by the 2-Minute Music Timer, ensuring they know when they've completed the session.
- Encourage gentle brushing of their tongue to remove additional plaque and keep their breath fresh.
- Reward them for a job well done!
Kid's Oral Care Recommendations
- Brush your baby’s sensitive gums and teeth using a soft-bristled toothbrush designed for babies aged 0-2, twice daily for two minutes per session. Once teeth are coming in, your baby is ready for fluorinated toothpaste!
- Protect your child's teeth by using Crest Cavity Protection Sparkle Fun Toothpaste. As their oral health evolves, kids continue to need effective cavity protection as they lose baby teeth and their permanent teeth start to grow. This Crest toothpaste fights against cavities, is gentle on tooth enamel, and with the fun-filled sparkles, makes for an enjoyable brushing experience.
- Once your child turns three, transition to an electric toothbrush to remove more plaque for healthier teeth and gums, such as the Oral-B Kids Electric Toothbrush for kids ages 3+ featuring Disney and Marvel characters.
- Foster healthy habits with the Disney Magic Timer App, which makes brushing fun and helps kids brush for up to twice as long.
- Schedule visits with their dental professional twice a year for thorough cleanings and checkups.

FAQs

When do infants typically start teething?
Teething usually commences around 4 to 6 months of age for most babies; however, this can vary considerably. Some infants may not begin teething until after 12 months, while a few might even be born with some teeth already present.

When do infants usually get their initial teeth?
The majority of babies develop their first teeth between 4 and 6 months of age. The primary teeth that typically emerge first from the gumline are the front bottom teeth, also known as the lower central incisors. Most babies should have all 20 of their primary teeth fully erupted by their third birthday.

How can I alleviate discomfort from teething gums?
Teething gums can cause significant discomfort for your little one. Try gently rubbing or massaging their gums with a clean finger or a soft-bristled toothbrush, such as the Oral-B Manual Toothbrush Baby 0-2 Years Featuring Winnie the Pooh. You can also offer your baby a chilled teething ring or a cool, damp washcloth to chew on to help soothe the discomfort.

What should be applied to a baby's gums during teething?
Gently rub your baby's gums with a clean finger or offer a firm, non-liquid-filled teething ring that has been chilled, not frozen. Avoid applying teething gels to your baby’s gums, as their ingredients can be potentially harmful to your little one.
