Recurring Mouth Ulcers: Causes and Solutions

Mouth ulcers that persistently recur or seem to ”fill up” repeatedly can be frustrating and uncomfortable. This condition, where an ulcer appears to heal but then returns or refills, is often a sign of a more complex underlying issue. Understanding the possible causes and available solutions can help manage this persistent problem effectively.

One common reason for recurring mouth ulcers is trauma to the oral tissue. This can occur from accidental biting, sharp edges on teeth or dental work, or even aggressive brushing. The initial injury causes an ulcer, and continued irritation from the same source can prevent proper healing or cause the ulcer to recur. In such cases, addressing the source of trauma is crucial. This might involve filing down sharp tooth edges, adjusting ill-fitting dental appliances, or modifying oral hygiene practices.

Certain nutritional deficiencies can also contribute to persistent mouth ulcers. Deficiencies in vitamins B12, folate, iron, or zinc have been associated with recurrent oral ulcers. A blood test can help identify any nutritional gaps, and supplementation or dietary changes may be recommended to address these deficiencies.

Autoimmune conditions, such as Beh?et's disease or lupus, can manifest as recurring mouth ulcers. In these cases, the body's immune system mistakenly attacks healthy oral tissue, leading to persistent ulceration. If an autoimmune condition is suspected, a referral to a specialist for proper diagnosis and management is necessary.

Stress and hormonal changes can also play a role in the recurrence of mouth ulcers. High stress levels can weaken the immune system and make the body more susceptible to ulceration. Similarly, hormonal fluctuations during menstrual cycles or pregnancy can trigger outbreaks in some individuals. Stress management techniques and hormonal therapies may be beneficial in these situations.

Certain foods or ingredients can trigger mouth ulcers in sensitive individuals. Common culprits include acidic foods, spicy foods, and foods containing sodium lauryl sulfate (often found in toothpaste). Keeping a food diary and identifying potential triggers can help in avoiding recurrences.

Viral infections, particularly herpes simplex virus (HSV), can cause recurrent oral lesions. While HSV typically causes cold sores on the outer lips, it can occasionally manifest as intraoral ulcers. Antiviral medications may be prescribed if HSV is suspected as the cause.

In some cases, recurring mouth ulcers may be a sign of a more serious condition, such as oral cancer. While this is less common, it's important to have persistent or unusually large ulcers evaluated by a healthcare professional, especially if they don't heal within two weeks.

To manage recurring mouth ulcers, several approaches can be helpful:

Maintain good oral hygiene to prevent bacterial infection.

Use a soft-bristled toothbrush and avoid irritating the affected area.

Apply topical treatments like benzydamine or lidocaine to alleviate pain.

Rinse with saltwater or chlorhexidine mouthwash to promote healing.

Consider using protective gels or patches to cover the ulcer and prevent further irritation.

Avoid known triggers, including foods that may exacerbate the condition.

Manage stress through relaxation techniques or counseling if stress is a contributing factor.

Address any underlying nutritional deficiencies through diet or supplementation.

If home remedies and over-the-counter treatments are not effective, or if ulcers are severe or frequent, it's important to consult a healthcare provider or dentist. They may recommend prescription treatments such as topical corticosteroids, systemic medications, or cauterization of the ulcer.

In some cases, a biopsy may be necessary to rule out more serious conditions or to guide treatment.
