Medicated toothpaste can't substitute for drugs of dental treatment, further more with a long-term application, it is harmful to people's health. For example, for a superficial caries of the dentin, if we go to hospital and get helped by doctor or any other dental equipment it is easy to cure. But if you just wanna treat it with medicated toothpaste, it'll be much severer until it develops to pulpitis. It is not rare happened clinically.
We should correct a comprehensive evaluation of the medicated toothpaste. In strengthen the hygiene of the oral dentition, reducing inflammation, and appeasing the oral mucosa the drug toothpaste can play a certain role. If dental problems has not yet formed, as a preventive or in order to prevent future recurrence of any dental problems we can applied to medicated toothpaste. But if the disease has caused the organic changes, such as cavities, pulpitis or due to stimulation of the calculus resulted in the gingival margin tissue swelling, congestion, erosion or caused the formation of periodontitis, it is futile to just simply resort to medicated toothpaste,even could get it worse. We'd better go to hospital with a professional treatment, maintain a good personal hygiene habit and at least have teeth scaled with dental scalers twice per year.
