What is the second to last tooth called

What is the second to last tooth called? We all know that the growth of our teeth is regular, and we will only replace our teeth once in our lifetime. Before the replacement of teeth, we are called deciduous teeth. At this time, all teeth are the same. After the replacement, everyone's teeth are slightly different. Every tooth has its name. Some curious people want to know what the second to last tooth is called. Do you know what it is called? If you want to satisfy your curiosity, come and take a look.

Our teeth start to grow at the age of 5 months. The teeth that grow at this time are called incisors. Around 10 months, two more incisors continue to grow outside the original incisors, for a total of 8 teeth on the upper and lower jaws. After the age of one, the first deciduous molars will appear in the upper and lower alveoli, and then canine teeth will grow when the child is close to two years old, followed by the second deciduous molars, until all 20 deciduous teeth have grown. When the child reaches the developmental stage of 6 or 7 years old and the tooth replacement is completed, which is around 12 years old, the number of teeth will grow to 28. The second to last tooth at this time is called the first molar. This is the number of teeth a normal person has, but in adulthood, some people may start to grow wisdom teeth. If one wisdom tooth grows, then the second to last tooth in this row should be called the second molar, and if two grow, they are naturally the third molars. In other words, each person is different, and it depends on the number of wisdom teeth that have grown. If there are no wisdom teeth, then it is the first molar.

Therefore, there is no fixed name for the penultimate tooth. For children, the number of teeth they have is incomplete until all their teeth are replaced, so parents should try their best to educate their children to have hygienic oral hygiene habits. After the teeth grow out, they are neat and white, which means they are healthy. Be careful not to touch them with your hands, because there are a lot of bacteria on your hands, which can easily cause gingivitis.

In our daily life, we should pay more attention to the prevention and treatment of dental diseases, because the oral cavity is a place where bacteria frequently pass through every day, and it is easy to be infected and lead to various inflammations such as periodontitis. People whose teeth have not fully grown should develop the habit of rinsing their mouths and brushing their teeth more often after meals to avoid bacterial residue. Adults should pay attention to smoking and drinking less, which can cause dark yellow teeth and oral diseases, and eat a light diet.

How to prevent tooth decay:

1. Prevention

1.) Prevention of dental caries starts during pregnancy

Well-developed teeth provide a solid foundation for anti-caries. In terms of improving the caries resistance of teeth, we must first ensure the various nutrients needed for fetal physical and dental development, and promptly supplement high-protein, calcium, vitamins and other nutrients during pregnancy to ensure the normal development of fetal tooth germs. Secondly, pregnant women should pay special attention to preventing the occurrence of various infectious diseases.

2.) Cultivate good oral hygiene habits in children

Because the pits and fissures on the occlusal surfaces of newly erupted deciduous teeth are narrow and deep, they easily hide bacteria and are a high-risk site for tooth decay. Paying attention to oral hygiene is the most critical part of preventing caries. Children should be educated to develop good oral hygiene habits from an early age, such as rinsing their mouths after meals, not eating sweets and snacks before going to bed, etc.

3.) Preventing uneven teeth helps reduce the occurrence of dental caries

Malocclusion can cause food to become stuck or retained, which can easily lead to caries. Therefore, it is necessary to prevent the occurrence of malocclusion. For example, during the tooth replacement period, retained deciduous teeth and supernumerary teeth should be extracted in time, and missing teeth should be repaired.

4.) Balanced nutrition and less sweets

The food of infants and young children should be diversified to provide rich nutrients needed for tooth development. They should also pay attention to chewing crude fiber foods, such as vegetables, fruits, beans, lean meat, etc. The fiber in these foods can rub the tooth surface when chewing and remove plaque attached to the tooth surface.

5.) Conduct regular oral examinations to detect caries early and treat them early. Children are required to have an oral examination every 3 to 6 months.

6.) The use of various fluoride products such as fluoride toothpaste, paste, aqueous solution, etc. can prevent dental caries.

7. Implementing pit and fissure sealing is a practical and effective method that can effectively prevent tooth decay. It can reduce the incidence of tooth decay by more than 90% and save children from the pain of tooth decay.
