Hello doctor,

I am getting an ulcer on the inner cheek of the mouth. It disappears on the second day. But, again reappears after 1 or 2 days. It is about 29th time I am getting the same place ulcer within three months.



Welcome to icliniq.com.

It could be a common aphthous ulcer also know as canker sore. It has various causative factors such as deficiency of vitamin, hormonal imbalance, psychological reasons such as stress, some kind of allergy such as for food or paste or mouthwash, accidental trauma, injury caused by the sharp cusp of tooth, and bacterial infection.

Your problem could be any of the above. To know the exact reason, kindly get a clinical examination and blood report. Appropriate supplements will be suggested if the reason is either anemia or nutrition deficiency. In case of constant poking of sharp tooth, it will be either polished or filled.

Meanwhile, observe the following to avoid further pain and recurrence. Please avoid hot and spicy foods and take lots of water to keep yourself hydrated. Rinse your mouth after every meal or do saline mouth rinse thrice daily.

If the ulcer hurts, a topical anesthetic like Dolojel or Hexigel can be applied over the ulcer with a clean finger. Visit your nearest dentist as soon as possible and get a complete oral examination done to identify the cause.

I hope this helps.
