I am a 32 year old male. Two years back one of my teeth become loose and because of that small amount of blood started to come while spitting. Also I was having pain while eating, so after two months I went to dentist and remove that teeth as the dentist told me there is no other option. After that everything becomes normal. Now two months back again my teen becomes loose and again blood coming while spitting. I don't wanted to remove the teeth as I heard that once we remove one teen then the other teeth my also become loose. So I started to use sensodine tooth paste and took diclogem tablet as I was having difficulty in eating. After few days I stopped taking tablet and I can eat with out pain but blood is still coming while spitting. Now my question is whether it is normal to swallow these small amount of blood as while sleeping it may not possible to spit. Is there any harm in swallowing? Please reply me asap. Thank you.
