Many patients do not realise that good oral hygiene and a healthy appearance have a significant impact on our dentition. The oral cavity is a common part of the respiratory and digestive systems. It is important to bear in mind that the oral cavity can also be the site of various lesions (cheeks, gums, palate) and in some cases require treatment. The oral cavity is also an area where various types of diseases can develop, often dangerous to a person's health.
