A healthy life starts with your teeth! However, a smile from the heart is always the most beautiful! And the most important part of a smile is white teeth. White lips and teeth are the goal of modern beauty lovers! A mouthful of “black teeth” makes it impossible to smile with confidence! Beauty is not just for adults! Children also need it, and its importance cannot be ignored during their growth process. Due to the structure of teeth and children’s diet and oral hygiene behavior, children often have discolored and darkened teeth, which affects their beauty and function. We can simply divide children’s teeth darkening into three categories: First, is the exogenous pigmentation Commonly speaking, is the food, drinks, drugs, etc. are ingested after part of the residue on the teeth, not timely and effective cleaning to remove, over time, it is precipitated on the teeth, so that the tooth surface coloring. However, the original structure and inner color of the teeth are not changed in any way. Such a situation can be solved by professional dentists for scaling or polishing. Endogenous tooth discoloration often occurs in teeth that have been traumatized, and the main cause is pulp (nerve) necrosis, other causes of pulp necrosis can also discolor the tooth. In this case, root canal treatment is needed to remove the necrotic pulp tissue and carry out aesthetic restoration. Third, it is the tooth structure damage caused by tooth decay (caries) that causes the tooth to become black. The biggest characteristic is that besides the color change, there must be the damage of tooth structure. In this case, it is necessary to carry out filling (filling and crown restoration treatment) or even endodontic root canal treatment to repair the defect and restore the aesthetics according to the specific situation. Regardless of the type of blackened teeth, parents should seek timely guidance and treatment from a professional dentist and take appropriate preventive measures for the specific case so that their baby can have a healthy, bright smile!
