When do babies start teething is a common question that many parents have. Teething is an essential milestone in a baby’s development and signals the beginning of their ability to eat solid food. Because teething can result in discomfort, irritability, and restless nights, it can also be a difficult period for both parents and babies. This resource offers a thorough response to this query, outlining the indications and symptoms, the teething schedule, and helpful hints for easing discomfort.

Understanding Teething: What You Need to Know

Baby teething is to be understood to go for the details on “when do babies start teething?”. Teething occurs when a baby’s first set of teeth begins to push through their gums. This process can be uncomfortable, but it is essential for their overall development. It is important to remember that teething is a gradual process, and each baby’s experience will vary.

Teething typically begins between 4 and 7 months, although some babies may start earlier or later. The first teeth to appear are usually the two lower central incisors, followed by the upper central incisors. Over the next two years, all 20 primary teeth (baby teeth) will emerge.

Every baby is different, and the signs of teething can vary. However, most babies experience some common symptoms during this time. These symptoms may include:

Increased drooling

Due to increased salivation brought on by gum irritation, babies frequently drool more than usual during teething. Wet clothing, a continual need for bibs, and occasionally skin irritation around the neck and chin are the results of this. The body naturally strives to relieve gum irritation and aid in tooth eruption by causing excessive drooling.

Chewing on hands or objects

In order to ease gum pain, babies naturally chew on anything they can get their hands on.  This covers domestic objects, fingers, and toys. Chewing offers relief by balancing the pressure and soreness in their gums. Although parents should make sure the items are safe to chew, it’s a common coping strategy for handling the discomfort of teething.

Irritability and fussiness

Babies who are teething may experience discomfort and irritability due to swollen and sensitive gums. Babies may have mood swings, cry more, and have trouble falling asleep. Bedtime is especially difficult because this irritability is frequently stronger at night. Babies may find it difficult to maintain their composure during the uncomfortable teething period.

Swollen or tender gums

You may notice your baby’s gums look red, swollen, or sore in the area where a tooth is coming through. The gums may appear irritated or inflamed, and your baby might be extra sensitive when you touch or clean them. This swelling is a sign that teeth are pushing through and can trigger discomfort, causing crying or fussiness.

Refusing food or difficulty nursing

The discomfort from teething may make it hard for your baby to nurse or eat solid foods. Babies might avoid their bottle or refuse certain foods because the pressure on their gums is too painful. Some babies may struggle with latching onto the breast due to irritation. Offering softer foods or chilled items might ease the pain and encourage eating.

Other symptoms, such as diarrhea, a little increase in fussiness, or a mild temperature, may also be experienced by some babies. These symptoms are usually modest, though.  It’s crucial to see a doctor if your infant exhibits severe symptoms, such as a high fever.

When Do Babies Start Teething? The Timeline

When do babies start teething? On average, most babies begin teething around 4 to 7 months, but the exact timing can vary. The eruption of each tooth follows a general pattern, but some babies might get their first tooth earlier or later.

Teething Timeline Breakdown:

4-7 months

The first teeth to emerge are the lower central incisors (bottom front teeth). These are the first to break through and are often the most noticeable. Their appearance signals the start of the teething process. As these teeth come in, babies may experience drooling and a need to chew on objects for relief.

6-10 months

Next come the upper central incisors (top front teeth). These teeth may come in shortly after the lower incisors, though some babies experience a gap between the two sets. The eruption of these teeth helps babies develop their ability to chew and bite.

9-12 months

The upper lateral incisors appear (the teeth next to the top front teeth). These teeth help create the “four front teeth” look and are essential for biting food. During this time, babies may become more fussy, and the discomfort in their gums can lead to reluctance to chew.

10-16 months

The lower lateral incisors come through (the teeth next to the bottom front teeth). As the lateral incisors emerge, babies start developing a fuller set of teeth necessary for more advanced chewing. Parents often notice that their baby may become more selective about food, especially if it causes discomfort.

13-19 months

Back teeth called first molars, which are used to crush food, start to erupt.  Compared to the tiny front teeth, these larger teeth frequently cause more discomfort.  Babies may have trouble eating meals as their molars erupt and may instead choose softer foods. The larger teeth may also cause parents to notice more drooling.

16-23 months

Canines (or cuspids) appear, which are the pointed teeth that sit next to the molars. These are also known as “eye teeth” because of their position near the eyes. Canines are essential for tearing food and are often the last to come through. This stage can be particularly tough for babies due to the pointed shape of the teeth.

23-33 months

The second molars emerge, completing the set of 20 primary teeth. The second molars, located at the back of the mouth, can be the most challenging to deal with due to their size. Once these teeth emerge, babies will have a full set of 20 baby teeth, which will eventually fall out to make way for adult teeth. The discomfort from these molars often leads to irritability, and some babies may have difficulty sleeping or eating solids.

This timeline serves as a general guide, but some babies may follow a slightly different pattern. It’s important to remember that there is a wide range of normal, and variations are completely normal.

Why Is Teething So Uncomfortable for Babies?

Teething is uncomfortable for babies because their gums must soften and swell as the teeth break through. This process puts pressure on the baby’s delicate gums, which can be sore and inflamed. The discomfort can also affect their ability to eat, sleep, or even focus on playtime.

Babies can experience different levels of discomfort depending on the tooth that is coming through. The first molars and canines tend to be more painful than the front teeth because of their larger size and deeper placement in the gums.

How Long Does Teething Last?

Teething is a long process that can last several years. The first set of teeth typically emerges by the age of 3, and after that, your child’s baby teeth will gradually fall out to make room for adult teeth. While the process can be tough, knowing when to expect certain teeth to come through can help you prepare for future teething episodes.

Both parents and babies may endure stress during the teething process. However, there are several ways to ease your baby’s discomfort and help them through the process.

1. Teething Toys and Rings

The purpose of teething rings and teething toys is to assist in relieving a baby’s irritated gums. These toys are made of a variety of materials and forms, and some even contain gel that may be refrigerated. A cooled teething ring can produce a cooling feeling that can partially numb the gums, relieving the discomfort that comes with teeth erupting.  Make sure the toy is safe for babies to chew on and free of BPA. Also, avoid freezing the toy as it may become too hard and harm sensitive gums.

2. Gum Massage

Gently massaging your baby’s gums with a clean finger can help alleviate some of the pressure and discomfort they’re feeling. This action provides a soothing effect, encouraging circulation and easing the swelling around emerging teeth. The gentle pressure can also relieve some irritability your baby may experience during teething. Use clean hands and a gentle touch, as the gums are sensitive during this time. This can also help your baby become accustomed to having their mouth touched, which is useful when brushing their teeth later on.

3. Cold Foods

Offering your baby cold meals like yogurt, purees, or cooled fruit will help soothe their gums if they have begun eating solid foods. In addition to providing a temporary numbing effect, cold meals give newborns a satisfying chewing texture. Some great options include chilled applesauce, cold mashed avocado, or pieces of chilled fruits like bananas or berries (if your baby is old enough to handle these). Always supervise your baby closely while they eat to avoid choking hazards, especially if food pieces are small.

4. Over-the-Counter Remedies

Over-the-counter treatments like teething gels or pain-relieving drops can help babies who are in more severe pain. Benzocaine and other mild numbing ingredients are frequently used in these products, which temporarily relieve gum irritation. Before taking any drugs, it’s crucial to speak with your pediatrician to make sure your child is safe and taking them as prescribed. Babies younger than two years old should not use teething gels that contain dangerous substances like benzocaine since they may have negative side effects. To prevent overuse, strictly follow dose directions at all times.

5. Extra Cuddles and Attention

Sometimes, all your baby needs is some extra love and attention. During this time, you can offer your infant comfort and emotional support by holding them, rocking them, or cuddling them.  A parent’s physical contact can be comforting to teething babies, who may feel more agitated and exposed. Your infant will feel less anxious when you hold them near. You can also distract your baby with gentle play, a favorite toy, or a soothing lullaby to take their mind off the discomfort.

What Happens After the First Teeth Appear?

Once the first set of teeth comes in, the teething process will continue until all 20 baby teeth have emerged. The primary teeth play an important role in your baby’s ability to chew and speak. They will eventually fall out around the age of 6, making way for adult teeth.

It’s never too early to start caring for your baby’s teeth. After the first tooth comes in, use a soft, baby toothbrush with water to gently clean the teeth. Avoid using toothpaste until your baby is able to spit it out (usually around age 2). This helps establish healthy oral hygiene habits early on.

Can Teething Cause Other Health Issues?

Teething can cause discomfort and irritability, but it is generally not associated with other serious health issues. Some babies experience mild symptoms like a low-grade fever, runny nose, or diarrhea during the teething process. However, these symptoms should be mild and temporary.

A pediatrician should be consulted if your child has a high temperature (over 101°F), ongoing diarrhea, or any other unusual symptoms. These can indicate a condition unrelated to teething.
