Most babies begin teething between 4 and 7 months of age, and while it's an exciting milestone, it can also bring drooling, sore gums, sleepless nights, and plenty of questions. As a board-certified pediatric dentist—and a mom myself—I've helped countless families understand what's normal during teething, what really helps, and when it's time to call your pediatrician. This guide covers everything parents need to know, from the first signs of teething to safe remedies and your baby's first dental visit.
A Note from Dr. Lis
As a board-certified pediatric dentist—and a mom—I know teething can feel overwhelming, especially with so much conflicting advice online. My goal is to help you understand what's normal, what really works, and when it's time to seek care, so you can navigate this milestone with confidence.
When Do Babies Start Teething?
Average age (4–7 months)
Early vs. late teething
Genetics
Premature babies
Why every child is different
Tooth | Typical Age |
Lower central incisors | 6–10 months |
Upper central incisors | 8–12 months |
Lateral incisors | 9–16 months |
First molars | 13–19 months |
Canines | 16–22 months |
Second molars | 25–33 months |
While every baby is unique, there's a general timeline for when those little chompers tend to make their appearance. Most babies start teething around 6 months of age, but it can begin as early as 3 months or as late as 12 months. Don't worry if your little one is an early or late bloomer – it's all within the normal range!
Typically, the bottom front teeth (lower central incisors) are the first to emerge, usually between 6 and 10 months. These are often followed by the top front teeth (upper central incisors) between 8 and 12 months. The process continues with lateral incisors, first molars, canines, and second molars, usually completing by around 3 years of age.
Remember, teething is a gradual process. Your baby might experience teething symptoms for several days before a tooth actually breaks through the gum. It's also common for teeth to appear in pairs, which means double the teething fun!
Baby Teething Symptoms: What's Normal?
Common Teething Symptoms
Increased drooling
Chewing on toys or fingers
Swollen or tender gums
Mild irritability
Changes in sleep
Mild decrease in appetite
Teething rash from drool
Teething symptoms can vary from baby to baby, but there are some common signs to watch out for. Increased drooling is often one of the first indicators that your little one is teething. You might notice your baby's chin, cheeks, or even chest becoming damp from all the extra saliva. This can sometimes lead to a teething rash around the mouth, which is perfectly normal.
Another telltale sign is your baby's desire to chew on everything in sight. This urge to bite and gnaw helps alleviate the pressure they feel in their gums. You might also notice your little one becoming more irritable or fussy than usual. Some babies may experience disrupted sleep patterns or a decreased appetite for solid foods during this time.
It's important to note that while mild discomfort is common, teething doesn't typically cause high fevers, diarrhea, or severe illness. If your baby develops these symptoms, it's best to consult with your pediatrician as they may be unrelated to teething.
Teething Symptoms That Are NOT Normal
Usually Teething | Call Your Pediatrician |
Mild fussiness | Fever over 100.4°F |
Chewing | Persistent diarrhea |
Drooling | Vomiting |
Swollen gums | Lethargy |
Mild sleep changes | Difficulty breathing |
As a pediatric dentist, I often hear parents wondering how to survive teething and when to seek help. While teething can be uncomfortable for your little one, it's important to recognize when symptoms might indicate something more serious. Let's explore some key points to help you distinguish between normal teething symptoms and signs that warrant a call to the pediatrician.
How Long Does Teething Last?
One of the most common questions parents ask is, "How long will this last?" The good news is that teething discomfort is usually temporary.
For each new tooth, your baby may experience symptoms like sore gums, drooling, fussiness, or disrupted sleep for a few days before the tooth breaks through the gums and for a day or two afterward. While the entire teething process lasts from infancy until about age 3—when most children have all 20 primary (baby) teeth—periods of discomfort tend to come and go rather than lasting continuously.
Every child is different. Some babies seem barely bothered by teething, while others may be more sensitive with each new tooth. It's also common for several teeth to erupt within a short period, making it feel like teething lasts much longer.
If your baby's symptoms seem unusually severe, continue for an extended period, or include a high fever, persistent diarrhea, vomiting, or extreme lethargy, it's important to contact your pediatrician. These symptoms are not typically caused by teething and may be signs of another illness.
Teething Myths vs. Facts: What Parents Should Know
Common Teething Myth | The Facts |
Teething causes a high fever. | Teething may cause a slight increase in body temperature, but it does not typically cause a true fever (100.4°F or higher). If your baby has a fever, it's important to contact your pediatrician to rule out another illness. |
Teething causes diarrhea. | Research has not found a direct link between teething and diarrhea. If your baby has persistent diarrhea, vomiting, or signs of dehydration, consult your pediatrician. |
Every fussy baby is teething. | Babies become fussy for many reasons, including growth spurts, illness, hunger, and developmental changes. While teething can cause irritability, it shouldn't be assumed to be the cause of every difficult day. |
All babies lose their appetite while teething. | Some babies eat less because their gums are sore, while others continue eating normally. If your child refuses to eat or drink for an extended period, contact your healthcare provider. |
Teething causes severe illness. | Teething may cause drooling, sore gums, chewing, mild fussiness, and disrupted sleep, but it should not cause severe pain, persistent lethargy, high fever, or other signs of serious illness. |
Dr. Lis's Advice for Parents
One of the most common questions I hear in our Eastchester office is whether every rough night means a new tooth is coming in. The truth is that babies experience many developmental changes during their first year. While teething can certainly make babies uncomfortable, high fevers, persistent diarrhea, or a child who seems very ill usually point to something else. When in doubt, trust your instincts and call your pediatrician.
Here are some specific situations when you should reach out to your pediatrician:
Your baby is under 3 months old and has a temperature over 100.4°F (38°C)
Your baby is over 3 months old and has a fever over 102°F (39°C)
The fever lasts longer than 24 hours
Your baby has diarrhea, vomiting, or a rash along with the fever
Your little one seems very sleepy or looks sick
You can't soothe your baby despite trying various teething remedies
Refusal to eat or drink
Persistent runny nose, cough, vomiting, or diarrhea
A rash that spreads beyond the face
Symptoms that continue for more than a few days
Importance of early dental visits
While we're on the topic of seeking help, let's talk about the importance of early dental visits. The American Academy of Pediatric Dentistry recommends scheduling your child's first dental visit by their first birthday or within six months after their first tooth appears. These early visits are crucial for several reasons:
They allow for early detection and prevention of potential dental issues
They provide an opportunity for you to learn about proper oral care for your baby
They help your child become comfortable with dental visits from an early age
Safe Ways to Soothe a Teething Baby
I've seen countless parents struggling to survive teething. Don't worry, I'm here to share some tried-and-true teething tips to help you and your little one get through this challenging phase. Let's explore some effective teething remedies that can provide relief for your baby's sore gums.
Safe teething toys
Refrigerated silicone teethers
One of the best ways to help your baby cope with teething symptoms is to provide safe teething toys. Look for teethers made of non-toxic, BPA-free, 100% food-grade silicone. These toys come in different designs and unique textures, perfect for massaging your baby's gums and alleviating discomfort.
Teething Rings
Solid teething rings are a great option. You can chill them in the refrigerator for 15 to 30 minutes before giving them to your baby. Just be careful not to freeze them completely, as this could harm your little one's sensitive gums. Avoid liquid-filled rings, as sharp teeth might puncture them and release potentially harmful liquid.
Teething Toys
Some teething toys have different textures on each end, providing various sensations for your baby to explore. The handles are designed to be just the right size for little hands to hold, making it easier for your baby to maneuver the toy in their mouth.
Gentle gum massage
Sometimes, the simplest solutions are the most effective when it comes to how to survive teething. Gently massaging your baby's gums can work wonders in relieving teething pain. Here's how to do it:
Wash your hands thoroughly.
Use your clean finger or a soft, damp washcloth.
Apply gentle pressure in a circular motion on your baby's gums.
Focus on the areas where you can feel or see teeth coming through.
This technique uses soft, even pressure to ease pain and discomfort. It's also a great way to bond with your baby during this challenging time. Remember to keep the massage sessions short, just a few minutes at a time, and gage your baby's reaction to see if it's helping.
Cold therapy ideas
Cold therapy can be incredibly soothing for teething babies. Here are some safe and effective ways to use cold to relieve teething discomfort:
Chilled washcloth: Dampen a clean washcloth, wring it out, and place it in the refrigerator for about 30 minutes. Once chilled, let your baby chew on it. The cold sensation will help numb the gums and provide relief.
Frozen fruits: If your baby is old enough for solid foods, try offering chilled or frozen fruits like bananas or berries. You can put them in a mesh feeder or pouch for easy and safe chewing.
Cool water: For babies over 6 months, offer a sippy cup of cool water. This can help soothe their gums and keep them hydrated.
Cold spoon: Place a metal spoon in the refrigerator until it's cool, then gently rub the smooth part against your baby's gums. This can help reduce swelling and provide temporary relief.
Remember, while these teething remedies can be helpful, every baby is different. You might need to try a few different techniques to find what works best for your little one. If you're ever unsure or if your baby seems to be in excessive discomfort, don't hesitate to reach out to your pediatrician for advice.

Helping Your Baby Sleep During Teething
Teething and sleepless nights often seem to go hand in hand. As the pressure from a new tooth increases, your baby may have a harder time settling down or may wake more frequently than usual. While you can't eliminate teething discomfort completely, a few simple strategies can help your little one rest more comfortably.
Stick to a Consistent Bedtime Routine
Babies thrive on routine. Keeping bedtime calm and predictable—with a warm bath, a story, cuddles, or a lullaby—can help your baby relax, even during teething. A familiar routine signals that it's time to wind down and may make it easier for them to fall asleep.
Offer a Chilled Teether Before Bed
A refrigerated (not frozen) silicone teether or a cool, damp washcloth can help soothe sore gums before bedtime. The gentle cooling effect may temporarily reduce inflammation and provide enough relief for your baby to settle more comfortably. Avoid freezing teethers, as they can become too hard and may irritate delicate gums.
Create a Comfortable Sleep Environment
A cool, quiet, and dark room can help promote better sleep. Dressing your baby in lightweight, breathable sleepwear and maintaining a comfortable room temperature—typically between 68°F and 72°F (20°C to 22°C)—can help prevent overheating and encourage restful sleep.
Offer Comfort and Reassurance
Sometimes, what your baby needs most is you. Extra cuddles, rocking, or gentle soothing can provide comfort during difficult nights. While it's natural to want to help, try to maintain your usual sleep routines as much as possible so temporary teething discomfort doesn't unintentionally create long-term sleep challenges.
Dr. Lis's Tip: If your baby seems especially uncomfortable at bedtime, talk with your pediatrician about whether an age-appropriate pain reliever may be appropriate. Medication should only be used as directed by your child's healthcare provider—not as a routine solution for every teething episode.

Frequently Asked Questions About Baby Teething
When do babies start teething?
Most babies begin teething between 4 and 7 months of age, although it's perfectly normal for the first tooth to appear as early as 3 months or as late as 12 months. Every child develops at their own pace, and genetics often play a role in when teeth erupt. If your baby hasn't cut a tooth by their first birthday, mention it to your pediatrician or pediatric dentist, but in most cases, a later start isn't a cause for concern.
Which tooth comes in first?
For most babies, the lower central incisors (the two bottom front teeth) are the first to appear, usually between 6 and 10 months of age. They're typically followed by the upper central incisors between 8 and 12 months. While this is the most common pattern, some children may get their top teeth first or experience a slightly different eruption order—and that's usually completely normal.
How long does teething pain last?
Teething discomfort typically lasts a few days before a tooth erupts and for a day or two afterward. While the entire teething process continues until about age 3, symptoms usually come and go rather than lasting continuously. Some babies experience very little discomfort, while others are more sensitive with each new tooth. If symptoms seem severe or persist for an extended period, it's best to consult your pediatrician.
Can teething cause a fever?
Teething may cause a slight increase in your baby's temperature, but it does not usually cause a true fever of 100.4°F (38°C) or higher. If your baby develops a high fever, appears unusually sleepy, or seems very ill, it's important to contact your pediatrician. Those symptoms are more likely to be related to an illness than to teething.
Can teething cause diarrhea?
Current research does not support a direct connection between teething and diarrhea. Some parents notice looser stools during teething, possibly because babies drool more and put more objects in their mouths, but persistent diarrhea isn't considered a normal teething symptom. If your child has frequent diarrhea, vomiting, signs of dehydration, or seems unwell, contact your pediatrician.
What is the safest teething toy?
The safest teething toys are made from 100% food-grade silicone or natural rubber and are specifically designed for infants. Choose BPA-free teethers that can be chilled in the refrigerator for added comfort. Avoid liquid-filled teethers that could leak if punctured and skip frozen teethers, which can become too hard and irritate delicate gums. Always inspect teethers regularly for signs of wear or damage.
Should babies sleep with a teether?
No. The American Academy of Pediatrics recommends keeping the crib free of toys and other loose objects during sleep to reduce the risk of injury and support a safe sleep environment. Instead, offer a chilled teether or cool washcloth before bedtime to help soothe sore gums, then remove it before placing your baby down to sleep.
When should I brush my baby's first tooth?
You should begin brushing as soon as the first tooth appears. Use a soft-bristled infant toothbrush and a rice grain-sized smear of fluoride toothpaste twice a day, especially before bedtime. Starting good oral hygiene early helps prevent cavities and establishes healthy habits that can last a lifetime.
When should I schedule my baby's first dental visit?
The American Academy of Pediatric Dentistry recommends scheduling your child's first dental visit by their first birthday or within six months after the first tooth erupts, whichever comes first. Early visits allow your pediatric dentist to monitor healthy development, provide preventive care, answer your questions, and help your child build positive associations with dental visits from the very beginning.
Can I give my baby medicine for teething pain?
If your baby seems especially uncomfortable, talk with your pediatrician about whether an age-appropriate pain reliever, such as acetaminophen or ibuprofen (for babies over 6 months), is appropriate. Always follow your healthcare provider's dosing instructions. Avoid teething gels containing benzocaine or homeopathic products that have not been recommended by your child's healthcare provider, as some may pose safety risks for infants.
