Objective: Tetracycline is an antibiotic that stops protein synthesis bacteria. All Tetracycline with high broad spectrum at therapeutic concentrations are essentially inhibits bacteria action. It is the first drug of choice in dentistry or may not be a valid alternative in patients with beta-lactam allergy form. Materials and methods: Among the side effects of tetracycline that gives us very worried, tissue staining teeth, which make them more or less intense yellow to brown or blue screw and forced conversion to enamel and dentin tooth color changes. Tetracycline administered to children occurs, causing unsightly stains teeth in through. Tetracycline in the process of calcification by a chemical called calcium chelate complexes fitted tissues. Then, occurs a light-induced oxidation reaction, creating a product that is responsible for tooth discoloration and is real. Results & Conclusion: As a result, tetracycline molecule that knows the way to the calcified tissues. This is an advantage that makes us aware of this. As a hypothesis, experimental work in molecular manipulation tetracycline, a chemical structure that is acting sensitive to photo oxidation and join groups as a way kind of bleaching agent. The use of tetracycline makes informed us some actions that damage to power white-out tooth tissue. Start of a research project with laboratory animals with permanent teeth start growing evolution, to study non-toxicity and effectiveness of tetracycline molecule has been studied experimentally. The ultimate goal of this paper is to obtain a non-harmful to human's formula, which is for pregnant women and children. In the process of development planning and regular teeth, ivory white attached to it, so that the teeth maintain, white in his mouth.
