<s>[INST] hi , I often have a small trace of blood in my mouth in the morning. It is not there every morning and i can go for weeks with nothing at all, then it may appear for days at a time. As soon as I rinse my mouth out with water it is gone. I am 43 and a very light smoker but am also over weight ! Any ideas what this could be and what I should do? Thankyou [/INST] From the description of the problem, I feel you have mild gum infection. Think of when you had your professional cleaning of your teeth done. If it was done more than a year ago, then I think it's time to visit your dentist. Any general practitioner can solve this problem. Smoking is also a risk factor for gum infection. Opt for a soft brush and donor brush your teeth vigorously. You can use any commercially available mouthwash for gargling. U should gargle at least for 60 seconds and donor rinse your mouth after that for half an hour. </s>
