The beginning of tooth calcification (start of training) occurs in the 5th or 6th month of pregnancy for all baby teeth. The first tooth appears in the mouth around the sixth month after birth, but it can be present from birth. 

The first baby tooth loss occurs around 6 years of age.

• Central incisors: eruption at 6-10 months/fall at 6-8 years

• Lateral incisors: erupt at 8-12 months/fall at 7-9 years

• Canines: eruption at 16-20 months/fall at 9-12 years

• First molar: eruption at 12-16 months/fall at 9-11 years

• Second molar: erupt at 20-30 months/fall at 10-12 years

Teeth brushing
As soon as there are teeth, they must be cleaned. You can use a small toothbrush with the right amount of toothpaste and the right amount of fluoride. It is also important to have your child properly followed by a practitioner as soon as the first teeth appear.

Chronology

Age-by-age monitoring

From an early age, a visit to the dentist at least once a year is recommended. Certain key moments of tooth eruption need to be supervised and monitored.

At 3 years old:
The twenty baby teeth are in principle in place. The practitioner examines them, possibly prescribes fluoride, gives advice on harmful habits such as sucking the nipple or thumb.

Is 6 years old :
The definitive first molars appear. These "6 year old molars" often go unnoticed because they grow behind baby teeth. They are essential for the stability of the other teeth which are organized around them. However, they are the most affected by cavities due to their situation, unfinished mineralization and pronounced relief. It is possible to protect them by the painless application of a resin in the hollow of the tooth: the fissure scellant.

At 9 years old:
The child is in "mixed dentition", with coexistence of temporary teeth and permanent teeth. The gums can be painful during eruption, the teeth are misaligned: all this does not facilitate good hygiene and promotes an increase in caries.

At the age of 12 :
The permanent teeth finish to set up, with in particular the second permanent molars or "12 year old molar". Like the first molars, they can be protected by sealing the grooves. Pre-adolescence often marks changes in eating behavior (snacking and sugary drinks), sometimes accompanied by lax hygiene. Also, braces, frequent at this age, are real traps for dental plaque. Brushing is therefore particularly important.

At 15 :
All the permanent teeth are now there. To keep them intact, it is essential to spot cavities as soon as possible, before they are painful. The dentist may be led to identify eating disorders: significant erosion of the internal surface of the teeth by repeated vomiting in the case of bulimia, for example. The practitioner can also warn the adolescent smoker about the harmful effects of tobacco on the gums (50% of adolescents have gingivitis).

At 18 years old :
This is the age when the third molars or wisdom teeth - if there are any and if there is room for them - appear on the dental arch. The practitioner may be required to monitor their development, or even to extract them. The child is now an adult and it will be up to him to take charge of his oral hygiene. An opportunity to remind once again the importance of brushing and a balanced diet.
