The development of the teeth of the embryo starts around the 5th or 6th week of intra-uterine life, thus it is sometimes even before the confirmation of your pregnancy! As soon as the beginning, you must be very careful about the food. Sticky and sweetened food must be avoided, but if however you eat some, you have to brush your teeth immediately.

Sugars and lack of tooth brushing cause the lowering of the pH of saliva under the critical point where the production of acid engages the process of demineralization of the teeth enamel, first step to the dental caries. The more frequent is sugar eating, the more the attack of enamel will progress towards less calcified parts inside the tooth (dentine and pulps).

Vitamins and minerals

Pregnancy requires a sufficient quantity of vitamins (A,B,C,D, etc.) just as of minerals (phosphorus, iron, calcium, etc.). The calcium of your teeth is stable, and the embryo cannot modify this structure. However, if your calcium consumption is insufficient (e.g.: dairy products), the embryo will draw on the calcium of your bones.

Dental treatments during the pregnancy

During the first quarter, it is advised to go to the dental hygienist. Knowing your state, she will carry out an evaluation of your dental condition, and will be able to advise you adequately. The hygienist will carry out a complete cleaning of your teeth, by removing all the deposits responsible for the decays and gum diseases (biofilm or dental plaque, tartar, spots).

Even if there is no danger with dental radiographies, they will be taken only after your pregnancy, except in case of emergencies (e.g.: abscess, fracture, etc.). If such is the case, the lead apron covering the abdomen will be always used, as for each take of dental radiography. When curative treatments are required, they usually can be planned during the second quarter of the pregnancy, and the products used (e.g.: anaesthetics) must not have any harmful effect on the foetus. However, some treatments will have to be postponed after the pregnancy (e.g.: whitening).

Pregnancy gum disease (or gravidic)

The hormonal modifications during the pregnancy can cause reaction at the level of the gums, and the presence of biofilm (dental plaque) can worsen this situation. Swelling, red blotches, sensitivity, and spontaneous bleeding are possible. It is important to maintain a good daily oral hygiene by the brushing, using a toothbrush with supple bristles and fluoride toothpaste, as well as the use of dental floss. Thanks to good care, the state of your gums will recover after the childbirth.

Premature birth and low-weight baby at the birth

Many studies have revealed that presence of toxins during periodontal disease (support of the tooth: gums and bones) can cause risks of premature birth or low-weight baby at the birth. These children have a lower resistance to the infections, and have more often anomalies of birth or development.


The brushing, using a small toothbrush with supple bristles, and the rinsing of the mouth with water or fluoride mouth-rinse, can contribute to decrease the gastric acid built-up on the teeth and the mucous membranes, as well as in saliva.
