I am getting blood from the mouth sometimes. i found that it is from below and sides of the tongue and not from the throat or teeth. nowadays it is becoming more frequent

I have an problem with my teeth like, black line stain in front of the teeth, so it looks very awkward, so could you please advice me to get rid of it??...

No one wants to find out that it took 9 hours at $60/hour to fix a particular computer problem when a brand new budget PC might be had for half the final bill. Having at least some idea of how much the grand total will be is important.
