Your mouth ulcers are chronic and recurrent.  Causes of mouth ulcers are numerous. You may need to visit a general physician multiple times to know the exact cause of your problem. So have patience and visit a general physician near you. Give him/her time to investigate your problem.

may be a chronic gastritis or nutrional deficiency . Any addiction of tobacco or other substances?

Chronic recurrent mouth ulcers despite normal B12 and Vit D are often caused by causes that go unchecked. Most common missed reasons: Iron or folate deficiency (get serum ferritin and serum folate tested — B12 alone being normal doesn't rule this out), Celiac disease/gluten sensitivity (causes persistent oral ulcers through gut inflammation — test anti-TTG IgA antibody), Zinc deficiency (often overlooked), and Sodium Lauryl Sulphate (SLS) in toothpaste which is a known trigger — switching to an SLS-free toothpaste (like Sensodyne ProNamel or any SLS-free brand) alone reduces ulcers in many patients. Stress is also a major trigger. Less commonly, Behcet's disease (especially if you also get genital ulcers or eye problems) needs to be ruled out with a specialist. The key is identifying the underlying cause rather than just applying gel.

Bechet disease, evaluation needed clinically .genetic involvement are HLA B51 .go for these genetic test.

Chronic recurrent mouth ulcers (recurrent aphthous stomatitis) can occur even when vitamin B12 and vitamin D levels are normal. Other possible causes include: • Iron deficiency or folate deficiency • Celiac disease or inflammatory bowel disease • Autoimmune disorders (especially Behçet’s disease if associated with genital ulcers, eye symptoms, or skin lesions) • Food hypersensitivity, stress, sleep deprivation, or local trauma • Certain medications (NSAIDs, nicorandil, etc.) Since your ulcers recur throughout the year despite topical gels, I recommend evaluation with CBC, peripheral smear, serum ferritin, folate, iron studies, and assessment for systemic symptoms. If ulcers persist for >2 weeks, are unusually large, or are associated with weight loss, fever, genital ulcers, or eye complaints, consult an oral medicine specialist/ENT physician for further evaluation and, if needed, biopsy.

Can also be due to infection,  viruses or anaerobic bacteria,  could be irritation due to keeping something in mouth for long time.

Hello. Experiencing persistent, year-long cycles of multiple mouth and tongue ulcers despite having completely normal Vitamin B12 and Vitamin D3 levels is a frustrating clinical challenge. When a standard vitamin profile and bowel habits are normal, the condition is often diagnosed as severe Recurrent Aphthous Stomatitis (RAS). Beyond B12, the recurring cycles can be triggered by other overlooked factors: localized micro-trauma, an underlying Zinc or Iron/Ferritin deficiency, chronic emotional or physiological stress, hypersensitivity to certain food proteins (like gluten), or a reaction to Sodium Lauryl Sulfate (SLS), a common foaming agent found in many commercial toothpastes.

Hello. Recurrent mouth ulcers are not always due to vitamin deficiency. Since your Vitamin B12 and Vitamin D are normal, other possibilities include recurrent aphthous stomatitis (most common), iron or folate deficiency, stress, local trauma, food triggers or less commonly autoimmune/gastrointestinal conditions (such as celiac disease or inflammatory bowel disease).

Get dental check up.

Chronic mouth ulcers can have many possible causes, such as nutritional deficiencies, infections, immune-related conditions, or other medical problems. Since your ulcers have been persistent, I recommend that you consult an ENT specialist for a proper examination, diagnosis, and further management.
