This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I just noticed a white spot on my gum, not anywhere near my teeth. I am scared of it. Kindly help.

Hello,

Welcome to icliniq.com.

Thank you for sharing the image (attachment removed to protect patient identity). Based on the information you have provided, it looks like an ulcer. It is a common ailment found in most people.

For a definitive diagnosis, I will need some more information. Since when did you notice this? Any history of trauma due to accidental lip biting or injury while brushing? What is the nature of the white spot? Does it pain or burn on touching and movement of the lip? Any allergies to any medication? Your diet? Nutritional deficiencies? Autoimmune disorders and blood disorders (rare)? What is your water intake per day?

Generally, oral ulcers tend to heal by themselves within 7 to 10 days. If there is pain or discomfort hampering routine activities like chewing or talking, a topical formulation like an antiseptic coupled with an analgesic gel can be applied to the ulcer directly for symptomatic relief. Also, a nutritional supplement rich in B-complex vitamins is prescribed to promote healing.

Treatment plan:

  1. Apply antiseptic and analgesic topical gel to the ulcer.
  2. Use nutritional supplements rich in B-complex vitamins.
  3. Drink at least three to four liters of water daily.
  4. Maintain a healthy diet and exercise routine.
  5. Practice careful brushing technique to avoid harming adjacent soft tissue.

Preventive measures:

  1. Brush twice daily with fluoride-containing toothpaste.
  2. Use interdental floss to clean surfaces, spaces, and contacts between teeth.
  3. Gargle with salt water daily, especially after meals.
  4. Clean the tongue regularly.
  5. Schedule a checkup with your dentist once every six months.
  6. Visit the dentist for oral prophylaxis (teeth cleaning and polishing) every six months.

I hope this helps.

Thank you.
