Thanks for asking the query,
Based on the information provided by you the symptoms which are present can be due to nutritional deficiencies, stress
, GIT disturbances or due to the use of medications used by you.
I would suggest you to consult your concerned Physician and get the antibiotics changed.
Maintain a good oral hygiene
, use antiseptic mouthwash gargles twice daily.
Avoid eating of hot and spicy foodstuffs, drink plenty of water and keep yourself hydrated.
Stop the habit of smoking
Hope this helps out.
