Let your wife visit a dentist
for real cause. Sometimes a sharp tooth cusp is the culprit. Otherwise she may be suffering from recurrent aphthous stomatitis for which only smyle gel or dologel
CT or orasore application will not help to stop recurrent ulcers. It requires scaling and polishing of teeth, regular tongue cleaning and specific medications such as Amlexanox
gel, rexidine m forte gel combined for 5 to 7 days. Once ulcers disappears she has to maintain oral hygiene by proper brushing, using chlorhexidine mouthwash twice daily. Taking vitamin B complex, selenium
etc. Will add to her general body health and hence the immunity. Even then, if it fails, which happens in many cases, contact us.
