Oral Pathology


Oral pathology is the area of dentistry responsible for diagnosing and treating lesions in the oral cavity, which can affect the hard tissues (jawbone structures and teeth) and soft tissues (gums, mucosa, tongue, lips) of the oral cavity, as well as attached structures (such as salivary glands).

Some of these pathologies may be related to medication, salivary alterations, viral infections such as Herpes or HPV, fungal infections such as candidiasis, or oral problems resulting from systemic diseases.


Existem algumas medidas que pode tomar para tentar detetar se tem uma patologia oral. Aqui está um guia passo-a-passo:

─ Observe the appearance of the upper and lower lips, the outer and inner areas, especially the gums;

─ Look inside the cheeks, throat and palate;

─ Palpate your face and neck to check for lumps;

─ Check the tongue, top, sides and bottom, taking the opportunity to analyze the floor of the mouth;

─ See a dentist or stomatologist regularly.

What are the characteristics of some of the most prevalent oral pathologies?

There are various oral pathologies, each of which has its own characteristics. Here are some examples.

Halitosis, commonly known as bad breath, is increasingly a reason to visit the dentist, who works on its diagnosis, treatment and prevention.

The root of this problem is usually food, which can cause bad breath either orally or systemically.

Burning in the mouth can affect not only the mouth, but particularly the tongue, causing pain. This burning sensation can be multifactorial and should be assessed by a specialist.

This type of problem is more common in women from middle age onwards.

Gingivitis is the first manifestation of periodontal disease, which is still at a recoverable stage as long as proper hygiene and prophylaxis are carried out by a dentist. The main symptoms of this problem are red, thick and bleeding gums.

We talk about periodontitis when the gingivitis is already at a more advanced stage and has already affected the periodontal ligament and the alveolar bone. Unlike gingivitis, the effect of treatment takes longer at this stage and there is a greater risk of tooth loss.

Contrary to what you might think, dry mouth can be a sign of some oral pathology, as it indicates that there is insufficient saliva production, which can be related to different factors, such as smoking, stress, anxiety,…

Having a blister on the lip, cheek or floor of the tongue may not be a rare situation, but it still requires attention on the part of the patient.

These blisters are often caused by the rupture of one or more salivary ducts. The cause of this rupture can be trauma, such as repetitive self-biting, or an obstruction of the salivary gland.

Leukoplakia is the name given to non-scratchable white plaques, usually asymptomatic, that appear in the mouth.

These plaques should be analyzed histopathologically in order to exclude other oral pathologies with similar characteristics, as well as to detect whether or not they are malignant.
