Baby teething symptoms - NHS

When it comes to teething, all babies are different. But your baby will probably get their first tooth some time during their first year.

Find out how to spot when your baby is teething and what order your baby's teeth are likely to appear in.

When do babies start teething?

Some babies are born with their first teeth. Others start teething before they are 4 months old, and some after 12 months. But most babies start teething at around 6 months.

Teething symptoms

Baby teeth sometimes emerge with no pain or discomfort at all.

At other times, you may notice:

their gum is sore and red where the tooth is coming through
they have a mild temperature of less than 38C
they have 1 flushed cheek
they have a rash on their face
they're rubbing their ear
they're dribbling more than usual
they're gnawing and chewing on things a lot
they're more fretful than usual
they're not sleeping very well

Some people think that teething causes other symptoms, such as diarrhoea, but there's no evidence to support this.

You know your baby best. Get medical advice if they have any symptoms that are causing you concern. You can call NHS 111 or contact a GP.

What order do baby teeth appear in?

Here's a rough guide to how babies' teeth usually emerge:

bottom incisors (bottom front teeth) – these are usually the first to come through, usually at around 5 to 7 months
top incisors (top front teeth) – these tend to come through at about 6 to 8 months
top lateral incisors (either side of the top front teeth) – these come through at around 9 to 11 months
bottom lateral incisors (either side of the bottom front teeth) – these come through at around 10 to 12 months
first molars (back teeth) – these come through at around 12 to 16 months
canines (between the lateral incisors and the first molars) – these come through at around 16 to 20 months
second molars – these come through at around 20 to 30 months

Most children will have all of their milk teeth by the time they are between 2 and 3 years old.

When Do Babies Start Teething? Symptoms, Remedies, and More

You love watching your baby hit those sweet milestones — the first smile, first giggle, and rolling over for the first time. But one that’s sometimes not so sweet (for you or for them) is cutting their first tooth.

Teething is when a baby’s teeth start to come through their gums. Although this is a typical part of growing for babies, it is one of those milestones that can bring discomfort, tears (from you and baby), and even sleepless nights (yep, more of those!).

As for when your baby will actually start the process, it depends.

A baby’s teeth can sometimes emerge with no pain or discomfort, so you might not realize they’re teething until you see the first sign of a tiny white tooth. For other babies, though, teething does cause discomfort.

Common symptoms of teething may include:

drooling
face rash from drooling
chewing on different objects
irritability and crankiness
crying
refusing to eat
swollen, sore, or tender gums
trouble sleeping
flushed cheeks
pulling on their ears
slightly elevated temperature to around 99°F (37.2°C)

Note

On the other hand, a rectal temperature 100.4°F (38°C) or higher, vomiting, or diarrhea are not usually signs of teething. If your baby has these symptoms, contact their pediatrician.

Symptoms of teething in breastfed babies

Teething symptoms can occur whether you breastfeed or bottle-feed your baby. But if you breastfeed or chestfeed, you might notice other changes, too. For example, gum pain or soreness might cause your baby to latch on differently.

Before a tooth emerges (and even afterward), you might feel your baby gnaw or bite down on your breasts. And since breastfeeding is soothing for babies, they might feed more often while teething.

Keep in mind that teething symptoms occur before a tooth breaks through the gum, so don’t be alarmed if you notice these changes in your baby but don’t see any sign of a tooth.

Most babies get their first tooth between 4 and 7 months old.

But there’s a wide range of when it’s considered “typical” to start teething. So don’t panic if your little one hasn’t cut a tooth by 7 or 9 months old. If you’re concerned, you can always speak with their pediatrician at their next checkup.

To get even more specific, most infants begin teething at around 6 months old. Your little one will likely have a full set of their first teeth by age 3, and all the joys of the teeth-brushing routine will have been long established.

But “typical” doesn’t mean “best” or “all.” Exactly when your baby will start teething may even be hereditary.

And though it may seem impossible, some babies are born with one or two teeth! This occurs in about 1 in 6,000 to 1 in 800 cases — so it’s uncommon. It makes for some incredibly adorable pictures, but let’s be honest — toothless grins are pretty darn cute, too.

Infants born with teeth should have them closely monitored since they can present a choking risk.

Some infants are early teethers — and it usually isn’t anything to worry about! If your little one starts showing signs of teething around 2 or 3 months old, they’re simply ahead of the curve in the teething department. And if your baby is a late teether, try not to worry about this either (easier said than done, we know).

Every baby is different, so don’t be concerned if all your child’s little friends have started to cut teeth already — yours will too, in their own time. In fact, if you’re going to compare at all, it’s better to consider when their siblings (if they have them) got their first tooth.

The bottom two teeth are usually the first to appear, followed by the four upper teeth. So keep an eye on that area and prepare for cuteness overload when they do.

Next, their teeth may come in two at a time, one on each side of the mouth. But this pattern can vary, and many factors can influence the timeline (like if your baby was born early or at a low birth weight, for example).

On average, babies have:

4 teeth by 11 months
8 teeth by 15 months
12 teeth by 19 months
16 teeth at 23 months

Those sometimes distressing (but always perfectly usual) teething symptoms may come and go during this time period. Or they may be more consistent as your little one cuts new teeth or starts to feel the first symptoms of a tooth emerging.

If your child doesn’t have any teeth by 18 months, see a pediatric dentist for evaluation. In rare cases, an underlying medical issue may cause a delay in teething. These may include:

malnutrition
vitamin deficiency
underactive thyroid

If you’re concerned that it’s been a while since your child cut their last one or two teeth, speak with their pediatrician.

When your little one is teething, you may feel more inclined to reach for that bottle of wine or chocolate bar because it’s tough to see your baby in pain. (No? Just us?)

Well, baby needs some soothing, too.

Home remedies

These are some tried and true — and most importantly, safe — home remedies you can try:

Gently massage your baby’s gums with a clean finger, knuckle, or moistened gauze pad.
Hold a cold washcloth, spoon, or chilled teething ring on your baby’s gums.
Use plastic or rubber toys that are chilled — never frozen solid (ouch!).
Offer cold foods like a chilled little slice of cucumber if your baby is already eating solids — but always keep a watchful eye on them, because this could be a choking hazard.

Medical treatment

Currently, there aren’t any medical treatments to soothe teething pain in a baby. The good news, though, is that babies typically respond positively to home remedies.

If these remedies don’t relieve symptoms, feel free to ask your pediatrician about the occasional use of over-the-counter baby acetaminophen or ibuprofen.

Your pediatrician can advise whether this is an OK treatment and provide guidance on proper dosing.

And an important note: No matter how attractive the item or the claims of its manufacturers, avoid teething necklaces or bracelets — worn by adults or babies — made of amber, wood, or silicone. These can quickly turn into choking hazards, and it’s just not worth it.

Also on the no-go list: homeopathic teething tablets and medicated topical gels. The Food and Drug Administration (FDA) has issued warnings against using both of these products.

Medicated topical gels contain the ingredient benzocaine, which is an anesthetic. It’s found in products like Anbesol, Orajel, Baby Orajel, and Orabase.

Benzocaine is linked to a rare but serious condition called methemoglobinemia.

Keep in mind that good oral health isn’t important for only older children, teens, and adults. Your baby’s oral health matters too. So start brushing those pearly whites as soon as the first tooth grows in.

How do you keep their tiny, delicate teeth healthy? There really isn’t much to do at this age, but the first step is to buy an infant toothbrush that is soft and gentle. You’ll brush their teeth twice a day, once in the morning and once at night.

And yes, it’s OK to use a fluoride toothpaste, but not too much. You only need a small grain-size amount until they’re 3 years old; then, increase to a pea-sized amount.

Brushing helps prevent tooth decay, which can occur when sugar from milk, juice, or formula remains on their teeth and damages the enamel.

Have questions about teething? Here are answers to a few frequently asked questions.

What are the first signs of teething?

The teething experience can differ for each individual baby, but some of the first signs include:

drooling
gnawing
trouble sleeping
irritability or crying
a mild increase in body temperature

Some babies also develop flushness around their cheeks or a rash. And if you breastfeed or chestfeed, teething might change the way your baby latches, or they might feed more often to soothe themselves.

How early do babies show signs of teething?

Teething typically occurs around 6 months of age. However, some babies start teething as early as 2 or 3 months. Then again, some babies teeth later and don’t cut their first tooth until 8 or 9 months (or later).

How long does teething last for babies?

The teething timeframe differs for each baby. But regardless of whether a baby starts teething at 6 months or 9 months, they typically stop teething before age 3. Some babies stop teething around 24 months, while others don’t stop until 36 months.

Do babies get sick when teething?

Even though your baby may have physical discomfort, teething doesn’t make them sick. So if your baby has a runny nose, productive cough, diarrhea, vomiting, or a high fever, these symptoms aren’t associated with teething. This could be a sign of an infection, so speak with their pediatrician.

When your baby cuts their first tooth usually says nothing about their development — as with most things baby, there’s such a wide range of totally OK. Most infants end up with a full set of baby teeth by the time they’re 3 years old, regardless of when they cut that first tooth.

But if your baby hasn’t cut a tooth by the time they’re 18 months old, talk with your dentist. Ideally, you’ve already brought your baby to a pediatric dentist by age 1, as recommended by the American Academy of Pediatric Dentistry (and the American Dental Association and American Academy of Pediatrics, too).

So if you haven’t seen a dentist yet, this would be a good time to have your sweet babe’s mouth and gums checked out.

While visiting the dentist for the first time may sound scary, remember these two things: Your baby hasn’t yet had a negative dental experience to create dread, and pediatric dentists are great at making the visit comfortable — it can even be even fun.

Once your little one does cut a tooth or two, be sure to take good care to clean around the area each day with a damp, cool washcloth or soft-bristle baby toothbrush. Before you know it, they’ll (hopefully!) be brushing their teeth on their own.

Teething in children, what you need to know

All parents know that teething is a difficult period in the life of every child, because he does not sleep well, is naughty and tries to gnaw everything he can reach. But the most dangerous thing is that at this time the baby is vulnerable to many infections. We will talk about how teeth should be cut normally, why the baby’s body cannot cope with the infection, and what symptoms indicate that it is time to go to the doctor.

Teething

Teething is a complex process, because at this time tissues are formed, teeth roots grow, gums are rebuilt. Moreover, the teeth begin to form even during pregnancy, starting from the 6th week. Around the same time, calcium begins to be deposited in the tissues of future teeth.

Next comes the most interesting part - teething. It is considered normal if the teeth begin to cut from 4 to 7 months. But each body is unique, so everyone's teeth are cut differently. It depends on many things, for example:

- From genetics. Often the age at which a child's teeth began to cut depends on when his relatives - mom, dad, grandparents - started teething.

- Power supply. If the baby lacks vitamins and minerals, such as vitamin C or calcium, teeth will start to erupt later.

- From the course of pregnancy. If there was fetal toxicosis during pregnancy, this will also slow down the appearance of teeth.

Also, teeth are normally cut in pairs, that is, first the lower central incisors appear, then the upper central incisors, the upper lateral incisors - the lower lateral incisors, the upper first molars - the lower first molars, etc. But even if the order is violated, this does not always mean any disease or serious violation.

When to sound the alarm

In places where teeth erupt, many biologically active substances are released, such as histamine, leukotrienes, prostaglandins, etc. They just cause the symptoms that every parent is familiar with:

- Fever. Normally, when teething, the temperature should be subfebrile, that is, no more than 38 degrees;

- Swelling, pain and redness of the gums.

There is a normal reaction of the child to teething. As a rule, the baby refuses to eat, but at the same time pulls toys into his mouth to gnaw on them. Due to the fact that the child is constantly chewing on something, the nerves of the gums are irritated and a lot of saliva is released, and since the child does not yet know how to control saliva, it flows out of the mouth. Also, the child becomes more excitable than usual - sleeps less, is constantly naughty, becomes irritable.

Life hack: to help your child and relieve toothache, buy a special teether toy. Such a toy can be filled with water and put in the refrigerator. When the baby chews on it, the toy will cool the inflamed gums and thereby partially relieve the pain.

But there are symptoms that parents often confuse with a normal reaction to the appearance of teeth:

- Digestive disorders - diarrhea, vomiting, loose stools;

- Temperature above 38-39degrees, which does not subside for several days;

- Cough, rash, swelling.

These symptoms indicate that there is an infection in the child's body that needs to be treated.

Why a child is so vulnerable to diseases

When a child chews on something, microtraumas and cracks appear on the gums. The mucous membrane, like other gum tissues, is not yet formed, so infections easily enter the body through these injuries. And since at the age of the appearance of the first teeth - from 4 to 7 months, the passive immunity received from the mother is gradually lost, and its own immunity is just beginning to be developed, the body cannot cope with the infection.

What should I do if my baby has unusual symptoms?

The only sure option is to see a pediatrician. The doctor will examine the baby and prescribe tests to prescribe the right treatment. And the doctor will also assess whether the teeth are erupting correctly and give useful advice for your child.

When does the baby's first teeth erupt?

All babies teething according to their own individual program: for some, this process begins earlier, for others later. As practice shows, the first tooth in most children appears at the age of 6 to 8.5 months, and by the year every healthy child has at least one milk tooth in his mouth.

At the age of three or four months, the teeth preparing for eruption begin to declare themselves quite actively: the baby becomes capricious, cries, tries to bite everything that gets into his hands.

The first to appear are usually the two lower, centrally located teeth (lower central incisors or "ones"). Then - the central upper incisors, after which, by about ten months, the upper "twos", or lateral upper incisors, erupt. By eleven to twelve months, the lateral incisors can also be seen on the lower jaw. Thus, ideally, a one-year-old child is the proud owner of eight milk teeth.

By about sixteen months, many babies already have first molars on the bottom and top. Fangs ("threes") appear at the top and bottom later, in the eighteenth - twenty-second month of a child's life. The second upper and lower molars erupt at the age of 24-33 months. But again, it should be remembered that this process is individual and the order of teething may also be different.

Teeth often grow in pairs: two, and sometimes four, at the same time. In girls, for the most part, teeth erupt earlier than in boys. By the age of 2.5-3 years, a complete set of twenty fully erupted teeth can be found in a baby.

Alertness must be shown if a child who is almost a year old does not have a single tooth. In principle, some children may have a congenital feature in the form of late teething, but you should not draw any conclusions on your own, you should definitely consult with a qualified specialist who, if necessary, will prescribe additional examinations.

Causes of late teething in children:

hereditary predisposition, which is a variant of the norm and can be traced in other blood relatives;
decreased thyroid function;
rickets;
diseases of the digestive system;
enzymatic (fermentative) metabolism disorders;
pituitary insufficiency;
lack of calcium in the child's body;
genetically determined diseases.

For the baby, the process of teething can take place in different ways. Some children practically do not experience discomfort, others suffer from pain, their sleep is disturbed, their appetite worsens, their temperature rises (up to 38-39 ° C), salivation increases, nasal congestion, wet cough (due to profuse salivation), constipation or, conversely, , increased stool.

Experts recommend starting caring for the child's oral cavity even before the first teeth erupt: in the morning and evening, before going to bed, the child's gums should be gently wiped with a swab previously moistened with warm water.
