Mouth Ulcers 2026 Hong Kong Dental Fee Guide: Causes, Fast Treatment & Soothing Diet Tips

Mouth ulcers (commonly known as "aphthous ulcers") are one of the most prevalent oral conditions in Hong Kong, causing intense stinging pain that interferes with eating and speaking. According to the Hong Kong Dental Guide, most mouth ulcers heal on their own within one to two weeks; however, recurring or persistent ulcers may indicate a more serious underlying health issue. This report takes an independent and objective approach to comprehensively analyse the causes and management of mouth ulcers, helping consumers make informed health decisions.

Understanding the early symptoms and characteristics of mouth ulcers

Analysing the Causes of Mouth Ulcers

To effectively prevent recurrence, it is essential to first understand the causes of mouth ulcers. Clinical data indicates that the causes can generally be grouped into the following categories: First, physical trauma — for example, ill-fitting dentures with sharp edges, excessive brushing force, or abnormally positioned wisdom teeth repeatedly biting the inner lining of the mouth. Second, immune system dysregulation or excessive psychological stress, leading to reduced resistance. Third, nutritional deficiencies — particularly a lack of vitamin B12, iron, or folic acid. Fourth, hormonal changes associated with the female menstrual cycle are also a common trigger.

Clinical Management & Fast Treatment Options for Mouth Ulcers

For patients seeking fast treatment for mouth ulcers, there are multiple management approaches available both over-the-counter and at the professional dental level. In mild cases, dentists generally recommend the use of mouthwashes and topical gels containing anti-inflammatory, analgesic, or antibacterial agents to cover the wound and relieve discomfort. If the ulcer is caused by physical injury from a tooth decay-related sharp edge, patients should promptly undergo a dental filling or tooth smoothing procedure. In addition, regular scaling and cleaning helps remove plaque and tartar, maintaining good oral hygiene and reducing the risk of bacterial infection worsening the ulcer. For persistent cases or those involving severe pain, a specialist may need to prescribe specific corticosteroid medications, or even perform a biopsy to rule out the possibility of a malignant tumour.

What to Eat with Mouth Ulcers? Pain Relief & Dietary Recommendations

During a flare-up, many patients are most concerned about what to eat with mouth ulcers to minimise irritation and promote healing. From a nutritional and dental care perspective, patients are advised to increase their intake of natural foods rich in B vitamins and vitamin C, such as dark green vegetables, papaya, and kiwi fruit. In terms of food texture, soft and easy-to-chew options are recommended, such as congee, tofu, and steamed egg. At the same time, patients should strictly avoid spicy, overly acidic, deep-fried, or hard foods (such as potato chips and hard biscuits), as these can cause secondary injury to the damaged oral mucosa and delay recovery.

Frequently Asked Questions (FAQ)

Q1: What does it mean if a mouth ulcer has not healed after more than three weeks?
A1: If an ulcer shows no improvement after three weeks and is accompanied by hardened edges, abnormal bleeding, or loss of pain sensation, this may be a warning sign of oral cancer, and prompt professional evaluation by a dentist or doctor is strongly advised. If the lesion involves a deep pulp infection or necrosis, a root canal treatment may be required to thoroughly eliminate the source of infection.

Q2: Are folk remedies such as applying coarse salt directly to the ulcer effective?
A2: This is strongly not recommended. Applying coarse salt not only fails to achieve fast treatment of mouth ulcers, but the high concentration of salt will severely irritate the delicate mucosa, causing the wound to become further inflamed and worsened.

Q3: My removable dentures constantly rub against my gums and cause ulcers — what should I do?
A3: If recurring ulcers are caused by an ill-fitting removable denture, patients can ask their dentist to readjust the denture base. Alternatively, patients may consider consulting a dentist about dental implants to restore a stable bite function and completely resolve the issues of denture looseness and mucosal friction.

How to Choose a Quality and Safe Dental Service?

In accordance with the dental fee reference and the advocacy principles of the Consumer Council, members of the public should exercise careful judgement when selecting a dental clinic to manage complex oral conditions. It is recommended to choose dental institutions that hold Day Procedure Centre accreditation, as such centres are required to comply with the Department of Health's stringent guidelines regarding infection control, air filtration equipment standards, and emergency care provisions. Whether seeking specialist advice for frequently recurring mouth ulcers or undergoing general dental care procedures, patients should ensure that the clinic provides a transparent fee schedule and rigorous instrument sterilisation protocols, in order to fully safeguard their medical safety and personal health.
