You may feel that it is a minor inconvenience. You might say you bit your cheek, or ate something too Recurring Mouth Ulcers? It Might Be a Sign That Something Is Wrong

It might be a small nuisance. You might tell yourself that you bit your cheek, or had something too hot to eat. But when mouth ulcers recur again and again month after month, they begin to seem more than an occasional problem.

For most, such painful ulcers become a daily reality that disrupt the three primary functions of having use of your mouth — eating, talking, and sleeping. What most people don’t realize is that re-occurring mouth ulcers can be your body’s way of silently sobbing for help — signaling a deeper, more underlying problem — perhaps a nutrient deficiency, or an immunology problem or even linked to your lifestyle.

At Partha Dentall we have a lot of patients who report frequent ulcers and have just dismissed it as something small, only for us to realize that it is connected to an underlying medical issue, nutritional deficiency, or stress. If you keep experiencing ulcers that continue to reappear, you need to quit ignoring the signs.

In this blog, we are going to address most of the factors concerning recurring mouth ulcers, the reasons behind them, when you should consult, and treatments if it is your child involved.

1. What Are Mouth Ulcers and Why Do They Occur?

Mouth ulcers are small open wounds that may occur in the mouth. They tend to be round or oval in shape with a white or yellow center and red outer ring. You may discover them in any area of the inside of your mouth but are most common just inside the lips, on the inner cheeks, beneath the tongue, or on the top of your mouth.

They usually go away by themselves within one to two weeks. But if you keep getting them repeatedly, there is a reason for it.

2. Recurring Mouth Ulcers Causes

Let’s talk about some of the more common recurring mouth ulcers causes. You may be surprised at how many of them might be due to normal aspects in your life.

1. Vitamin Deficiencies

The most frequent cause we are finding in patients who suffer from chronic mouth ulcers is one of a vitamin and/or mineral deficiency, with low iron, folic acid, and vitamin B12 being most frequent.

These minerals and vitamins are crucial in tissue health, such as that of the inner lining of the mouth. If you don’t provide your body with the necessary minerals and vitamins, it is more likely for ulcers to develop and will tend to last longer.

2. Emotional Stress

Everybody is aware that stress can affect our bodily health. While some present stress as headaches or tummy problems, others present stress as mouth ulcers. If a person gets mouth ulcers on a regular basis during times of stress or when they are busy; then stress may be a likely culprit.

3. Food Sensitivities

Certain people’s ulcers may be caused by certain foods if they’re sensitive. The types of trigger foods would be acidic fruits (oranges and lemons), spicy foods, coffee, nuts, and possibly even chocolate. Not everybody is sensitive to these foods, but if you do get ulcers on a regular basis then it would be worth it to perhaps take a food diary to see if there were connections.

4. Mouth Injuries

Occasionally, ulcers are simply an unwanted byproduct of a bite while eating. Braces can irritate and cause ulcers, sharp teeth, rough/broken fillings, or an ill-fitting denture also create ulcers. If you always develop an ulcer in the same location in your mouth, perhaps take note of how much rubbing occurs there.

5. Autoimmune and Gut Conditions

In some cases, frequent ulcers are linked to more complex health issues.

Although less common, conditions like celiac disease, Crohn’s disease, and Behçet’s syndrome can manifest as painful and frequent ulcers in the mouth. These conditions lead to the immune system attacking components of the bodies, including mouth tissues. Though this is rare, it is a significant cause to eliminate if you have other signs of stomach pain or fatigue.

6. Hormonal changes

Often overlooked but you must know that hormonal changes can influence the immune system and inflammation, making ulcers in the mouth more likely.

7. Viral Infections

Mouth ulcers may result from viral infections such as herpes simplex virus (don’t mix up with canker sores) and other infections that are generally linked to ulcerative-type lesions of the mouth. Aphthous ulcers may result from a viral infection, which will often have other symptoms like fever or swollen glands and would require an antiviral to heal.

3. Mouth ulcers in Child – Things parents need to know 

If your child experiences frequent ulcers, it can be worrying. Kids may find it difficult to eat, talk, or brush their teeth, and younger children will simply not have a way of explaining why their mouth is sore.

There are plenty of the same possible causes of mouth ulcers in children as there are in adults — deficiencies, stress, trauma from aggressive food or brushing, etc. Mouth ulcers may also reflect viral diseases such as hand-foot-and-mouth disease, particularly if they are accompanied by fever or rash.

If your child keeps getting them, or they don’t go away in a few days, they should be evaluated by a paediatric dentist or physician. They will check out the cause and give them gentle treatment based on your child’s comfort level and age.

4. When To Worry

Most mouth ulcers are harmless and will go away by themselves. There are some times when the ulcer might need extra attention.

You should bring your child to a health care provider if:

• they have ulcers more than two weeks in length, not treated

• they have recurrent ulcers more than once a month

• they have very large or painful ulcers

• they have ulcers with other signs such as fever, malaise, or weight loss

• they have ulcers in the same location every time

• you see ulcers together with other symptoms of the digestive system.
