Oral Skin Conditions

Oral skin conditions, sometimes called oral mucosal diseases, affect the skin-like tissue that lines your mouth. Some are localised to the mouth, while others are linked to skin or systemic conditions.

Some common skin conditions treated at Welbeck include:

• oral ulcers

• oral lichen planus

• oral candidiasis (thrush)

• geographic tongue

• eczema on the lips

• sun damage (actinic cheilitis) to the lips

• orofacial granulomatosisp

• pigmented lesions

• altered taste or sensation (oral dysaesthesia or burning mouth syndrome)

• leukoplakia

• oral pemphigus or pemphigoid

Many of these conditions are not serious but can be uncomfortable or affect your quality of life. Some, however, may need further investigation to rule out cancerous changes.

Symptoms depend on the type of condition and which part of the mouth is affected. Common signs include:

• red, white, or mixed patches on the tongue, cheeks, gums, or lips

• burning, pain, or discomfort in the mouth

• persistent ulcers or sores that do not heal within 3 weeks

• cracked or dry lips

• swelling of the lips or mouth lining

• bleeding gums (unrelated to gum disease)

• difficulty eating or swallowing

• changes in taste or loss of taste

If you have a sore, patch, or ulcer that lasts longer than 3 weeks, it’s important to get it checked by a specialist, as it could be a sign of a more serious problem, including early mouth cancer.

The causes of oral skin conditions vary widely. Some are local irritations, while others are immune-related or due to infections.Common causes include:

• infections – such as fungal (oral thrush), viral (cold sores, HPV), or bacterial infections

• allergic reactions – to dental materials, mouthwash, toothpaste, or certain foods

• autoimmune diseases – such as lichen planus, lupus, or pemphigoid, where the immune system attacks the body’s tissues

• trauma or irritation – from biting the inside of your cheek, sharp teeth, braces or dentures

• nutritional deficiencies – such as iron, folate, or vitamin B12 deficiency

• smoking and alcohol – these increase the risk of chronic oral irritation and leukoplakia

• medication side effects – such as from chemotherapy or antibiotics

Some oral skin conditions have no known cause but are thought to be triggered by stress, hormonal changes, or other health conditions.

Our specialists will begin by talking to you about your symptoms before carrying out an examination of your mouth. In some cases, a physical examination will be enough to diagnose an oral skin condition, but other diagnostic tests may sometimes be needed.Depending on your symptoms, your consultant may also perform:

• a biopsy – taking a small tissue sample for microscopic examination

• swab or culture tests – to check for bacterial or fungal infections

• blood tests – to identify autoimmune diseases or deficiencies

• patch testing – if an allergic reaction is suspected

• imaging scans – such as ultrasound or MRI, for deeper tissue concerns

In many cases, a diagnosis can be made during your consultation, allowing for early treatment to reduce symptoms and prevent complications.

While not all oral skin conditions can be prevented, there are steps you can take to reduce your risk or avoid flare-ups:

• maintain good oral hygiene by brushing twice a day and flossing regularly

• avoid tobacco and limit alcohol intake

• eat a balanced diet rich in fruits, vegetables, and whole grains

• avoid foods or products that irritate your mouth, such as spicy foods or strong mouthwashes

• use alcohol-free mouthwash or toothpaste designed for sensitive mouths

• keep dentures and dental appliances clean and well-fitted

• manage stress with regular exercise and relaxation techniques

For patients with known autoimmune or allergic oral diseases, following your specialist’s care plan and attending regular reviews is important to prevent recurrence.

Most oral skin conditions are benign and treatable, but if left untreated, they can lead to complications such as:

• chronic pain and discomfort when eating or speaking

• secondary infections, particularly if ulcers or cracked skin become infected

• difficulty eating or swallowing, which may lead to weight loss

• psychological distress, especially when symptoms affect speech or appearance

• precancerous changes, as seen in leukoplakia or chronic lichen planus (rare, but important to monitor)

Regular follow-up with your consultant helps to monitor any changes and reduce your risk of complications.

Treatment depends on the underlying cause and severity of your condition. Common options include:

• topical corticosteroids – to reduce inflammation and soreness

• antifungal medication – for conditions like oral thrush

• antiviral medication – for viral infections such as herpes simplex

• immunosuppressive drugs – for autoimmune conditions such as oral lichen planus or pemphigus

• pain relief gels or mouth rinses – to reduce discomfort while healing

• vitamin or iron supplements – if deficiencies are identified

• lifestyle and diet advice – to manage triggers and support oral health

Your consultant will discuss all suitable treatment options, explain what to expect, and tailor your plan to your individual needs.
