How many teeth does an average child have

Teeth development in children - Better Health Channel

The development of primary teeth begins while the baby is in the womb. At about 5 weeks' gestation, the first buds of primary teeth appear in the baby's jaws. At birth, the baby has a full set of 20 primary teeth (10 in the upper jaw, 10 in the lower jaw) hidden under the gums. Primary teeth are also known as baby teeth, milk teeth or deciduous teeth.

Types of teeth

The names of the different types of teeth are:

Incisors – the front teeth located in the upper and lower jaws. Each incisor has a thin cutting edge. The upper and lower incisors come together like a pair of scissors to cut the food.
Canines – the pointy teeth on both sides of the incisors in the upper and lower jaws; used to tear food.
Premolars – which have flat surfaces to crush food.
Molars – these are larger than premolars towards the back of the mouth, with broad, flat surfaces that grind food.

Teething

'Eruption' refers to the tooth breaking through the gum line. In babies, tooth eruption is also called teething. The timing of tooth eruption differs from child to child. For example, one child may cut their first tooth when only a few months old, while another may not start teething until they are 12 months old or more.

The exact timing may be different from child to child but the order of tooth development is more consistent.

Generally, the average child has their full set of 20 primary teeth by the age of 3 years.

Managing the teething process

Babies’ immune systems start to change when they are around 6 months old. Along with the tendency to put things in their mouths, this makes them more prone to illnesses. Symptoms of common childhood illnesses such as changes in sleep and eating patterns, fussiness, rash, drooling, runny nose and diarrhoea are often linked to teething when that might not be the cause. If your child has these symptoms, speak to your child’s doctor about other possible causes such as bacterial, viral or middle ear infections.

Teething takes about 8 days, which includes 4 days before and 3 days after the tooth comes through the gum. (You may see a blue-grey bubble on the gum where the tooth is about to appear. This is called an eruption cyst and will usually go away without treatment.) During this time, it can be tough to keep children comfortable.

Some tips include:

Massage – gently massage the gum with clean fingers or a soft, wet cloth.
Chilled (not frozen) teething rings or rusks – pressure from a cold object can relieve discomfort from teething. Do not sterilise plastic teething rings in boiling water or dishwater, unless specified by the manufacturer. Be sure to check product information before buying teething rings. Avoid the ones that use a plastic softener called 'diisononyl phthalate'.
Unsweetened teething rusks or sugar-free teething biscuits – these can be given to infants over 6 months who have started eating solids.
Pain-relieving medications – paracetamol works well for children. Ibuprofen may also help, but it is not as well tolerated by children.
Dry the drool – the skin around the mouth, particularly the chin area, can become irritated. Gently wipe this away with a soft cloth throughout the day.

Some treatments should be used with caution or not at all. These include:

Teething necklaces – amber is believed by some people to release healing oil on contact with warm skin. The oil is thought to be soothing or help to reduce pain. Although amber teething strings or necklaces are designed to be worn around the neck, wrist or ankle, they have been incorrectly used to chew on. The ACCC has issued a product safety statement about amber teething necklaces, warning of possible choking and strangulation hazards. Parents are asked to consider other less risky ways of providing relief from teething.
Teething gels – common teething gels contain 8.7–9.0% of the ingredient choline salicylate. Salicylate is related to aspirin. The use of aspirin for children younger than 16 is not recommended because in some children it has been known to cause Reye's syndrome – a rare but potentially lethal condition that can cause liver and brain damage. Although there has not been a reported case of Reye's syndrome associated with the use of teething gels, the general advice is that it is a risk not worth taking when there are other things available.

Teething gels containing benzocaine are also not recommended for use in children. Research also suggests that teething gels may not relieve teething pain, rather the act of massaging it into the gum is what helps.

Caring for baby teeth

Some parents may feel that caring for baby (primary) teeth isn't as important as caring for adult (permanent) teeth, simply because baby teeth fall out.

However, baby teeth are very important. They allow children to chew food and speak properly, and they reserve the spaces in the gums for future adult teeth.

Tooth decay in baby teeth

Tooth decay is preventable. The risk of developing dental decay can be significantly reduced by good oral hygiene habits and a healthy diet from a young age.

Decayed baby teeth need to be treated by a dental practitioner. In some cases, specialist treatment in a hospital under a general anaesthetic is needed. If neglected, decayed baby teeth can lead to mouth pain, dental abscesses (a boil or swelling resulting from infected teeth), and problems with the surrounding teeth. Severe decay in baby teeth can affect eating and sleep, which can slow growth.

If a baby molar is lost too early due to severe decay, adjacent baby teeth may drift into the gap and create spacing problems for the adult tooth when it comes through.

Loss of baby teeth

From the age of about 6 years, baby teeth start to become 'wobbly' and fall out to make way for adult teeth. It is perfectly normal for a child to lose their first tooth up to a year or 2 earlier or later than 6 years of age. Girls generally lose teeth earlier than boys. The first tooth to fall out is usually located in the front of the lower jaw.

Losing baby teeth can be unsettling and painful for young children. Suggestions for parents include:

Reassure your child that losing baby teeth is a natural process and new adult teeth will come in their place. It's normal for gums to be tender and bleed a little, although some children experience little or no discomfort while losing their teeth.
Use cold packs or over-the-counter anti-inflammatory or pain-relieving medication to help relieve loose tooth pain. Ask your dentist or pharmacist for recommendations on appropriate medication for your child.
Make use of the Tooth Fairy. This myth has lasted a long time with good reason! The idea of getting some money or another reward in exchange for a tooth might soften the idea of tooth loss for your child.

Permanent teeth

Permanent teeth are also known as adult teeth or secondary teeth. The permanent teeth start to develop in the jaws at birth and continue after a child is born. By about 21 years, the average person has 32 permanent teeth, including 16 in the upper jaw and 16 in the lower jaw. (In some cases, the third molars – commonly called wisdom teeth – do not develop or do not erupt so some people only have a set of 28 permanent teeth.)

At about the age of 6 years, the first permanent molar teeth erupt. These 4 molars (2 in each jaw) come out behind the child's baby teeth. Other permanent teeth, such as the incisors, canines, and premolars, erupt into the gaps in the gum left by baby teeth that are lost.

As with baby teeth, the timing for when the permanent teeth come through can differ. Generally, the order of and rough timeline for each type of permanent tooth is:

First molars – between 6 and 7 years.
Central incisors – between 6 and 8 years.
Lateral incisors – between 7 and 8 years.
Canine teeth – between 9 and 13 years.
Premolars – between 9 and 13 years.
Second molars – between 11 and 13 years.
Third molars (wisdom teeth) – between the ages of 17 and 21 years, if at all.

Mouthguards protect children's teeth

Mouthguards help protect teeth and prevent dental injuries, particularly when playing and training for contact sports. All children playing contact sports should wear a custom-fitted mouthguard, even primary school-age children. Custom-fitted mouthguards are comfortable, allow speech and do not restrict breathing.

How Many Teeth Do We Have?

Baby Teeth

Children begin teething around six months of age, meaning that their teeth start coming in around that point. These first teeth are known as baby teeth, primary teeth, or, technically, deciduous teeth. As you know, they eventually fall out and are replaced by adult teeth.

How many teeth do children have? Children have 20 baby teeth. That includes 10 teeth on the top and 10 teeth on the bottom. All 20 of them usually come in before the age of three and act as placeholders for the adult teeth that grow in after the baby teeth fall out. At about age six, most children begin to lose their baby teeth, which are then replaced with adult teeth. This process continues until kids reach their early teen years.

It's important to mention that just because baby teeth fall out doesn't mean that they don't need care like adult teeth. Oral care routines should begin before a baby's first tooth comes in. This can be done by running a clean, damp washcloth over the baby's gums. Once the first tooth comes in, parents can brush the baby's teeth with an infant toothbrush and a tiny bit of toothpaste. Flossing can begin once the baby's teeth touch.

Adult Teeth

When adult teeth come in, there's more room in the mouth and more teeth. How many teeth do adults have? Most adults have 32 teeth, which is 12 teeth more than children! Among these 32 teeth are 8 incisors, 4 canines, 8 premolars, and 12 molars, including 4 wisdom teeth. It is very common for adults to have their wisdom teeth removed because there is not always enough room for them to grow in comfortably or without causing misalignment of other teeth. Most people have a complete set of adult teeth by the time they reach their teenage years.

Conditions That Affect The Number of Teeth

Tooth loss is a surprisingly common condition. And periodontal disease (aka gum disease) is the main reason adults lose their teeth. Luckily, prevention is possible. It involves brushing twice a day and flossing daily.

Other reasons for tooth loss include:

Tooth decay
Ectodermal dysplasia (a genetic disorder that can affect teeth)
Gastrointestinal reflux (severe tooth erosion which causes stomach acid to come up into the mouth)

Beyond tooth loss, there's also a condition called tooth agenesis, where teeth are missing in the mouth. It can either appear as the absence of all teeth or as 1 to 6 or more teeth missing. This condition is genetic and rare.

There are also circumstances where extra teeth, or supernumerary teeth, appear in the mouth. The most common type of supernumerary tooth is an extra incisor located between two central incisors.

Now you know the deal about how many teeth we have. Typically, children have 20 teeth, and adults have 32 teeth (28 if the wisdom teeth are removed). Remember that each one of them needs your care, even baby teeth. There are some cases where the number of teeth varies, resulting from tooth loss, tooth agenesia, or having extra teeth. So keep up with your oral hygiene no matter how many teeth you have. It'll help make sure your teeth stay healthy and happy.

Number of teeth in temporary and permanent occlusion

As you know, at birth, a child has absolutely no teeth in the oral cavity. There are only rudiments of milk crowns in the jaw. Then they are cut through, and in a strict definite sequence. Over time, the milk bite is replaced by a permanent one, with which a person lives all his life. In this regard, many parents are concerned about the eruption of crowns, timing and order. Consider how many teeth should be at a given age. nine0003

How many teeth should be in the milk bite

The first temporary teeth classically appear six months after birth. At the age of 6-7 months, the first central incisors appear. At the same time, the lower teeth appear first, and after them, with an interval of 4-6 months, the upper ones also enter the oral cavity.

Lateral incisors appear next in the child's mouth. They are slightly smaller in size than the central ones. As in the previous case, the lower lateral incisors should erupt first, and a little later their upper antagonists. nine0003

Contrary to the logical continuation of the sequence, after all the incisors have completely entered the oral cavity, the canines are next, but the molars. The first molar should appear first, 13 months for the lower, and 14 months for the upper antagonist. Only after that, at 16-17 months, should all fangs appear. And the last to enter the oral cavity are the second molars, at about 20 months.

Of course, all these terms are average and by no means are a firm rule for every child. The interval for the appearance of each crown is approximately six months from the estimated time. So, if the expected tooth suddenly has not yet appeared, do not rush to get nervous and be patient. nine0003

Thus, at about 2 years old, a child should have exactly 20 crowns in the mouth in the sum of both jaws.

How many teeth should be in permanent occlusion

In order to properly respond to a change in the bite of a child, it is necessary to understand in what order the permanent teeth appear. If you think that the order is the same as in the case of milk bite, you are a little mistaken.

It is very important to remember - the first molar is the first to change. While the very first central incisors that appeared are still strong and stable, at 6-7 years old, six are already ready to appear. At the same time, it does not replace the first milk molar, but emerges from the gum behind the entire milk dentition. Remember: Temporary large molars are precursors to adult premolars .

After the first permanent molars, the change goes in sequence, starting with ones. At 7-8 years old, the central incisors fall out and are replaced, at 8-9years - lateral, and in the period from 10 to 12 years, milk molars are successively replaced by permanent premolars. The classic rule also applies here: first bottom, then top .

At the age of 13, the process of forming a permanent bite continues, the second molar is born. It has no predecessors, respectively, nothing falls out before its eruption.

The completion of the formation of a permanent dentition occurs at about 15 years of age - the last to be replaced by fangs. By that time, the entire dentition has already been formed quite rigidly, which is why so often there is not enough space for the canine and it is dystopic, more often vestibular. The normal dentition includes 28 teeth, and the third molars are very variable, they can appear both above and below up to 25 years, and may be absent even in the form of rudiments. nine0003

How many teeth should a child have? – news and articles Refformat

The answer to the question "how many teeth does a child have?" is not as simple as it might seem at first glance. The child's body changes almost every month - this also applies to teeth. Today we will try to figure out how many of them should be in different age periods.

How many baby teeth do children have?

Dairy and even some molars begin to form even at the stage of intrauterine development. Of course, a child does not have visible teeth at birth - they begin to erupt only after 6 months. During this six-month period, they are hidden under the gums, but slowly develop and form, starting to move outward. nine0003

In total, the child grows 20 milk teeth:

Central and lateral incisors - 8.
Fangs - 4.
First and second molars - 8.

Their main function is to form a space where molars will then grow.

How many teeth should a child have per year?

During this period, milk teeth begin to cut. They begin to break out in the following sequence on the upper and lower jaw. nine0003

Top:

8-12 months. Central incisors.
9-13 months. Side cutters.
16-22 months. Fangs.
13-19 months. First molars.
25-33 months. Second molars.

In the lower jaw, this process is distributed in time somewhat differently:

6-10 months. Central incisors.
10-16 months. Side cutters.
17-23 months. Fangs. nine0044
14-18 months. First molars.
23-31 months. Second molars.

It is worth noting that these time limits are averaged and deviations up or down by 1-3 months is considered the norm.

If you want to know how many teeth a child has per year is considered the norm, you should be guided by the above chart. You get that at the age of 12 months they should be 6-8.

Change of milk teeth to molars

Somewhere from the age of 4, a child’s growth spurt begins, the jaws increase and the milk teeth seem to move apart, gaps appear between them - three. If this does not happen and by the age of 5 the teeth are still tight, you need to show the child to the dentist, as there may not be enough space for permanent teeth.

At about 5-6 years old, milk teeth begin to loosen and gradually fall out, which indicates that molars are already starting to grow under them. Usually this process of change stretches for 5-8 years and the final formation of the dentition occurs somewhere around the age of 14-15. nine0003

This happens in the following order:

5-6 years old - lower and upper incisors.
7-8 years - lower and upper lateral incisors.
8-10 years - upper and lower molars.
9-11 years old - upper and lower canines.
11-13 years old - upper and lower molars.

Milk teeth are replaced by permanent molars. Their number at the age of 14-16 is 28. At the same time, the third molars (wisdom teeth) are already formed, but they begin to grow only after 18 years. True, not all people grow them. It all depends on individual characteristics. nine0003

How many teeth should a child have?

It all depends on age. The maximum number of teeth in the period from birth to 5-6 years is 20 - these are milk teeth. Then, until the age of 15-16, the molars begin to erupt, pushing out the milk teeth. Ultimately, their number grows to 28.

The latest are the third molars.
