<s>[INST] 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, there's no other option [/INST] 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 a oral physician and get a MRI done to rule out arterovenous malformation. if it is a dilated vessel then no need of any treatment. If it is a arterovenous malformation, then it has to be treated with sclerosing agents.I hope my answer will help you, take care. </s>
