I have canker sores. it that something to worry about? and it is regular. i am having it at least thrice or more in a month

I would encourage: you not to worry. But I would check with your dentist due to marked frequency with which you have them. Take care.

Canker sores: I agree with Dr. Fowler about seeing your dentist. Many factors can contribute to canker sore. These include stress, trauma, vitamin deficiencies, hormonal, sensitivities to SLS, sodium lauryl sulfate, in many tooth pastes, try changing toothpaste to SLS free, you will need to read the labels, and also see a dentist

Canker sores: are not pleasant and can be very painful. Canker sore is the most common oral lesions. Individual ulcers typically last 1-2 weeks. The condition is idiopathic (the cause is not known) and recurrent aphthous ulcers are usually self-limiting. Your dentist may prescribe an antimicrobial mouth rinse corticosteroid ointment to control the pain and irritation.
