Hi sir...   Bleeding gums indicates poor oral hygiene... soft and hard deposits(plaque and calculus) leads to Gingivitis(gingival inflammation),gum recession, bone loss(periodontitis)loosening of teeth and finally tooth loss Eventhough you brush well there is always some inacessible area that needs to be clened(scaling)  by dentists

Visit your dentist and get a good scaling/cleaning done. Take some vitamin C supplements for few days n easy food rich in vitC.  You can do rinsing with lukewarm water with little salt As you r young these things should settle down your problem

Hi Bleeding gums is a very common issue and is a sign of weak or unhealthy gums but it should not be taken lightly. You need to visit your dentist/or periodontist (gum specialist) and get your periodontal assessment done to get rid of the symptoms. A thorough cleaning or deep cleaning shud be the propable treatment of choice (depending upon the xray findings & how severe the condition is) which can be managed in one or two appointments.

Hi there. Bleeding gums is a very definitive sign of gum disease . You would need a good round of cleaning and specialist will prescribe some mouthwashes that would help you regain the tonicity of ur gums. You could set up an appointment with me( as I am a gym specialist). Sensitivity could occur either due to gum issues or dental caries( most common). I would need to see you to addresss that issue.
