Thanks for asking the query,
Recurrent mouth ulcers occurs due to many reasons like immunlogic defects, vitamin & iron deficiencies, traumatic self inflicted bites , toothbrushing and dental trauma
, hormonal imbalance, allergic factors.
You have traumatised the tongue accidently while eating, dont worry apply Dologel oral ointment topically over the affected area,

Maintain a good oral hygiene
, use saline water gargles, antiseptic mouthwash gargles.
