Tetracycline During Pregnancy

Tetracycline is an antibiotic that is effective against many infections and used sometimes to treat Acne. Other antibiotics in the same family are minocycline and doxycycline.

Taking Tetracycline during pregnancy affects the development of the bone and the teeth in the fetus. As Tetracycline has a negative effect on the calcification process in the bone and the teeth, this result in the baby teeth being discoloured and the permanent teeth suffering from enamel hypoplasia (incomplete development of the enamel).

The critical period for calcification begins at the fourth month of pregnancy and ends twelve months after birth. Therefore, pregnant women should avoid taking the drug after the sixteenth week in the pregnancy and throughout the breast-feeding period.

Whitening could improve the appearance of your teeth but is often not enough to reach the desired result. Covering the teeth with crowns or veneers is preferable in this case.

Make sure you inform you dentist or doctor that you are pregnant before taking any medication.
