Answer: What's your diagnosis? – Case 26

Mrs D woke up one morning with a swelling on the right side of her face. It turns out that a dental abscess might be the cause of her problem.

Based on her history and examination, Mrs D is most likely suffering from a dental abscess. In such cases patients classically experience a swelling of the face. Only when asked if they suffer from toothache will patients admit that a tooth has been giving them problems. On examination, the suspicious tooth should be noticed.

All swellings should be examined by a doctor

Dental abscesses can be very painful, but in some cases the patient will not necessarily experience pain, only swelling. The patient might have spiking fevers. Abscesses should be treated as quickly as possible. The patient will be referred to a dentist to remove the affected tooth and drain the abscess. The dentist will prescribe antibiotics.

Read: Facial Swelling

Distinguishing between abscesses and other causes of facial swelling is not always straightforward. One has to exclude allergic reactions and also make sure the swelling is not affecting the airways of the patient. Ear, nose and throat causes need to be excluded. In the absence of dental problems, an ENT surgeon will examine the patient and exclude soft tissue growths (which develop over time, rather than overnight), and infections of the nose, sinus cavities and ears.

In the case of sudden onset swelling, a medical opinion is urgently needed – especially if the overlying skin is red, tender and the patient has fever, facial weakness or draining of fluid or pus from the mouth or nasal cavities. All swellings should be examined by a doctor.
