There may be plaque accumulation and tartar just under the gums where they meet the teeth
you need medication against the specific bacteria causing gum bleeding,which is usually the earliest sign of gum disease(Gingivitis) and also a professional cleaning from a Dental surgeon.
If the oral ulcers are persistent may need to rule out other possibilities by your Dentist.Keep using mouth washes till you meet the Dentist

hi, you are having swelling in your gums which is referred as gingivitis there can be many causes behind it, start using an ultrasoft toothbrush and rinse your mouth with warm saline water 4-5 times daily (1 tsp salt in 1 glass water) also massage your gums with tan-x gel before sleeping at night.

Hello & welcome,
Generalized Bleeding & swollen gums are clear indication of having Gingivitis which is nothing but the infection & inflammation of gingiva due to accumulation of plaque in gigival sulcus ( where gingiva meets tooth surface ).
Improper cleaning habits usually leads to the same condition. But here, you are having ulcers,too.
Ulcers may be due to stress or any other underlying systemic condition which may be diagnosed & treated accordingly.
Deficiency of vitamins which might sometimes be caused by alcohol intake ( like vit. B12 ) is also responsible for presentation with ulcers.
Use of topical anesthetic gel or mouth wash, Antibiotics to prevent secondary infection & anti-inflammatory drugs to reduce inflammation is advised under dentist's supervision.
To know underlying cause of ulcers, you can go for detailed blood examination & rule out more severe conditions like anemia.
Maintain your oral hygiene with proper brushing techniques or get your teeth cleaned by a dentist.

Take care.

Hello and thank you for your question.
Based on what you have spoken about it sounds like you have acute necrotizing ulcerative gingivitis (ANUG). This is a condition caused by a bacterial infection in your gums. This tends to occur when under large amounts of stress, becoming medically compromised or having poor oral hygiene. You need to be seen by your dentist, have a thurough cleaning and be placed on antibiotics to get rid of the infection. Brushing and flossing will help but you need the assistance of dental intervention by a dentist to help improve you situation.

Best wishes and good health.
