<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have noticed recently my vessels along the bottom sides of my tongue are darker but one side, my left is like a huge cluster and plum color. What could this be an indication of? I hate going to the dentist, more recently because I had a dentist ruin two teeth the same day, now they sit in my mouth, broke because I dread knowing they now have to be pulled, theres no other option  <response>: Thanks for your query, I have gone through your query. The vessels along the floor of the mouth or below the tongue could be a varicose vein or dilated sublingual vein. Nothing to worry it is benign condition, I will not harm you. If there is any change in the size then consult an oral physician and get an MRI done to rule out arteriovenous malformation. If it is a dilated vessel then no need of any treatment. If it is an arteriovenous malformation, then it has to be treated with sclerosis agents. I hope my answer will help you, take care.
