What Causes Difficulty In Opening The Mouth?

Hi... Welcome to healthcare magic. As you mentioned you have habit of eating tobacco ... Oral submucous fibrosis(OSMF) lead to limited opening of mouth.. First stop to eat tobacco.. Antioxidant and multivitamins drugs helpful .. Steroid therapy also helpful. Physiotherapy give more relief.. mention how much your mouth opening present.. Normally three figures mouth opening.. take ice cream sticks bunch and put it into mouth and forcefully open a mouth... In bunch of stick add one by one stick every day.. Consult a dentist he or she give you this advise how to do this physiotherapy... After oral examination of mouth give exact idea that OSMF at which stage... Avoid stress.. Avoid spicy foods also because of OSMF burning sensation occurs.. If all this treatment not work than surgery is a last option. I hope my guidance helpful to you.. Get well soon.. Still you have any problems than consult again. Thank you.
