Hello, Thank you for your inquiry. I understand your concern and agree that any calcifications in the neck are of great concern. If the carotid artery is suffering from stenosis, there is a risk of less oxygen going to the brain. The diameter of the blood vessel is reduced. A cerebrovascular accident or stroke is possible. Quick action is necessary. Lifestyle changes and medications will be considered. Cholesterol reducing medications and blood thinners are common medications prescribed. If your condition is severe, immediate surgery such as a angioplasty to widen the blood vessel may be needed. A balloon widens the artery and a mesh placed in the artery keeps it open. If a vessel is more accessible, surgery to remove the calcifications can be performed. If your symptoms include severe headaches, dizziness, numbness, speech difficulties, or confusion, this may indicate a greater threat of a stroke and seek immediate care. You are fortunate that your dentist has advised you of this condition and you may be treating the condition before any severe symptoms put you at a greater risk. Plan to share your MRI with your doctor. Thank you for your inquiry. I hope you feel better soon.
