Hi! Welcome to Healthcaremagic. I read your query. Gum bleeding is the first sign of gum disease. However, detachment of gums from teeth occur at later stages of disease which may involve heavy bleeding, bad breath,pain, etc. I suggest you visit a Periodontist and get your gums checked. You will be required to go multiple times. You will be given oral prophylaxis and curettage if required. Usually with proper cleaning, medicine, maintainence of hygiene and nutrition, the gums start to re-attach with in 2-3 months. Else further treatment like flap surgery may be required. Along with treatment, you need to maintain good hygiene. Brushing twice daily with soft tooth brush, mouthwash, warm saline rinses, gum massage, proper diet, multivitamins. You may be prescribed antibiotics and anti inflammatories. Take lots of fluid, fruits, vegetables like spinach, carrot, lemon, etc. Hope the answer helps you. Thank you.
