Hello, Additional information on your condition including a full medical and dental history would be helpful. Dental X-rays would provide great deal of information. Consider consulting another dentist for a second opinion with X-rays and a clinical exam. Consider scheduling an appointment with a general dentist or prosthodontist. Your periodontal health should be fully evaluated and consider working with a periodontist if there is any bone loss responsible for the need to remove teeth. Recurrent decay or decay on tooth structure below a crown is a common reason to replace a crown. You need a healthy amount of tooth structure and supporting bone remaining to consider replacing a crown. Your overall health can affect your rate of decay. People with the common side effect of a dry mouth often see an increase in the rate of decay on with their teeth. Recession can expose root structure that is not protected by enamel. Stress such as grinding your teeth, aggressive brushing and an acidic diet can erode tooth structure. Compromised periodontal conditions and a compromised bite can contribute to this condition as well. Is this description what you refer to as resorption? There are autoimmune conditions that concern the oral environment. Definitely inform your immunologist of your dental condition. Your dentist should be aware of your full medical history and any changes in your health. I commonly consult with specialist before proceeding with dental treatment on my patients. I am available to assist further if you can provide additional details. Thank you for your inquiry.
