Only those who have had canker sores know how uncomfortable they can be

Associated factors 

The factors associated with the formation or worsening of canker sores are: 

• Oral trauma - for instance, caused by brushing too vigorously, accidental bites on the tongue or inside the cheek, among other 

• Stress and anxiety 

• Hormonal factors - hormonal changes and menstrual cycle 

• Family history/genetics 

• Unbalanced diet, such as - Lack of certain nutrients, for instance, mineral salts (iron and zinc) or vitamins (especially vitamin B12 and folic acid) 

• Dental problems (movement of badly positioned or sharp teeth) or poor oral hygiene 

• Weakened immune system, some diseases (for example, helicobacter pylori which, as it happens with reflux, can be associated with changes in oral pH, Crohn's disease, systemic lupus erythematosus, celiac disease; ulcerative colitis, HIV infection) 

• Reaction to medicinal products (anti-inflammatory or antihypertensive drugs) 

• Certain foods: chocolate, coffee, strawberries, cheese, almonds, sour fruits (lemons, oranges) 

• Allergy to sodium lauryl sulphate found in several toothpastes and elixirs.
  
  

• Healthy diet: foods rich in vitamins and minerals 

• Eat soft and easy to chew foods (vegetable soups, purees) 

• Drink cold drinks, such as water and teas 

• Avoid talking while chewing and swallowing 

• Visit your dentist more often 

In the treatment of canker sores, some products may be recommended to help relieve symptoms: 

• Antiseptic and antibacterial solutions (mouthwashes, gels or drops) 

• Protective gel for oral mucosa 

• Painkillers for pain relief 

• Homeopathic medicinal products 

• Extra soft toothbrush (does not hurt when brushing your teeth) 

• Vitamin complexes 

Canker sores are rare in babies. Babies usually suffer from “oral thrush”, an infection caused by fungi that requires a specific treatment.
