Causes of children’s molar cavities & 7 things to know! Molars play a key role in chewing food to grind it before it can enter the airway.

What are molars?
Molars or molars, are teeth located inside the jawbone like wisdom teeth, or more correctly, molars will be the group of teeth in positions 4,5 (two small molars) and 6,7,8 (3 large molars) between the upper and lower jaws. Molars play an important role in keeping the jaw muscles balanced and in chewing and grinding food before it is absorbed by the digestive system.
In terms of the structure of molars, the size of the molars is much larger than the other teeth. The structure of the teeth also consists of two parts: the body of the tooth and the root of the tooth, which are connected by the neck of the tooth.
The body of the tooth is located on the outside and can be observed. The body of the tooth is located on the mouth of the tooth and consists of 5 main surfaces: the chewing surface, the outer surface, the inner surface and two side surfaces. According to research, the chewing surface is the widest surface compared to the other surfaces and often collides strongly with other teeth. The chewing surface is also responsible for chewing and grinding food.
The tooth root is usually firmly attached to the jaw bone to make the tooth more stable. Regarding molars, there are also tooth roots, but depending on the type of tooth and its development position, the number of tooth roots can be different. However, the number of tooth roots will also fluctuate between 2-3 roots. In the case of two roots in the molars, the roots are longer.
Specifically, the first short molar in the upper jaw consists of one lingual root and one lingual root. The first and second molars in the lower jaw consist of one distal root and one mesial root. In the case of three roots, the teeth in the first and second molar positions of the upper jaw will have two lingual roots and one lingual root.

When do children get molars?
Normally, molars will grow around 6 months old and the baby teeth will consist of 20 teeth. Until the age of 6, the first primary molar or commonly known as tooth number 6 will appear. After the baby teeth have fully grown, children will enter the stage of replacing new teeth.
Therefore, between the ages of 7-12, children will begin to lose their baby teeth and grow some other teeth, the teeth that grow later will be permanent. Over time, the teething process will take place in each stage in the following age order
- Around 6-12 months old: Eruption of central incisors
- Around 9-16 months old: Eruption of lateral incisors
- Around 16-23 months old: Eruption of canines
- Around 13-19 months old: Eruption of first molars
- Around 22-24 months old: Eruption of second molars
This time period is not complete for all children because the tooth replacement process in children may occur closer or later than this time frame, but they will grow in the correct order mentioned above and within that certain time period.
So with the time table, we also know exactly at what age the child will have the first molars, which is when the child turns 1 year old. Therefore, mothers need to pay attention when the child has some unusual manifestations for a long time, such as the effects of molar eruption.

Causes of children’s molar cavities
Molar teeth play an important role in learning to chew and swallow food. At the same time, the position of molars in the middle of the jaw makes them susceptible to many potential risks of tooth decay like other teeth. Besides, the awareness of children and parents in oral care and protection of children’s teeth is not paid much attention. Therefore, tooth decay in children is not uncommon.
Food is still stuck on the teeth but is not cleaned properly when used for a long time, this plaque is an opportunity for some bacteria to develop on children’s teeth, causing oral diseases, of which tooth decay is the most common case.
In addition, children at this stage of development are also very interested in other types of food and drink. Usually, these foods contain a lot of sugar, but this type of sugar will create acid that breaks down tooth enamel and causes them to erode and create holes in the molars. Normally, saliva acts to lubricate teeth and gradually whiten these cavities.
However, eating these sugary foods for a long time will cause the amount of saliva in the child’s mouth to no longer be able to lubricate the teeth as well as the enamel surface. From there, the enamel begins to erode, creating many stains that are considered cavities.
Parents often think that baby teeth can be completely removed and grow back like permanent teeth over time, which also affects their children’s oral hygiene.
However, they do not know that replacement is very important for the child’s teeth later on, as this type of baby teeth will play an important role in helping the permanent teeth not to be misaligned later on, and they also need to be kept strong and clean to ensure oral health as well as create conditions for new teeth to grow normally later.

The harmful effects of children’s molar cavities
Playing a major role in chewing and grinding food, when the molars are in pain due to tooth decay, it will also cause certain limitations in children’s chewing ability. Food is not chewed thoroughly when going down to the stomach. This makes the stomach have to work many times when chewing and swallowing food. Over time, the digestive system will be affected and lead to many intestinal diseases, especially in babies because tooth decay can affect the child’s life later on.
If tooth decay becomes more serious, it will cause children to feel itchy and uncomfortable, which will also affect their digestion. Eating becomes difficult, which can cause children to be lazy to eat, have poor appetite, and often skip meals due to toothache. This directly affects the health and resistance of children, especially children in puberty.
If tooth decay progresses rapidly and occurs early, the child needs to have all teeth extracted before the age of tooth replacement (children can replace teeth at 6 years old). Therefore, when the tooth is extracted but the tooth still does not grow, the gum will harden, making it difficult for the permanent molars to grow later, making the teeth prone to growing backwards or pressing forward, affecting the structure of other molars later as well as the aesthetics and health of the child’s teeth. In addition, if tooth decay is not treated early in children, it will cause complications and diseases that affect the child’s future oral health such as pulpitis, gum abscess, gingivitis, …
Do children’s molar cavities grow back?
Do children’s molar cavities grow back? In fact, thanks to the tooth replacement process, some baby teeth in children will be lost and grow back, so if there is tooth decay in these baby teeth, if it occurs during the dental work process, it is completely possible to cut them off and avoid tooth decay and then new teeth will grow up to replace them.
For the larger teeth are the small molars in the set of baby teeth that grow in infancy. After they are old enough to change teeth, these teeth will automatically break and fall out to make way for new teeth to emerge and grow. Usually, the molars located in number 1 and number 2 in the middle of the two rows of baby teeth will fall out. In place of these fallen baby teeth are new teeth that are firmer and make it easier for children to chew food.
For molars that do not replace or grow back, it can be said that they are the 3rd molars or commonly known as teeth in positions 6 and 7 in the baby teeth set. Their teeth grow back completely separately and do not interfere with the process of replacing baby teeth. That is, they grow very quickly and last a long time.
Teeth in positions 6 and 7 will grow in the final stage. According to research, tooth number 6 will grow in children around 6-7 years old and tooth number 7 will grow when children are 12-13 years old or older. This is a group of teeth that plays an important role in the daily eating and chewing process. Moreover, these are the types of teeth that are difficult to replace or grow back, so they need to be taken care of more carefully to help children chew better.
It can be seen that molars play an important role in children’s chewing learning process. Because not all molars can be easily replaced and grown back, every parent needs to pay attention to their children’s oral hygiene as well as instruct their children to take good care of their teeth to prevent dangerous diseases in the future and help their children’s oral health develop more comprehensively.
