I keep having nightmares about my teeth breaking off in my mouth. what is wrong with me?

You Are Very Normal: There are many fears that emerge in nightmares. The most famous is finding yourself talking to a group of people and discover you are naked. The next most common, i believe, is yours where teeth are falling out. See your dentist for a comprehensive dental exam including x-rays & periodontal & decay charting. They can then tell you if there is any oral reasons to worry about teeth falling out.

Stress: Dreams stimulate positive and negative emotions. At age 47, the body and hormonal changes can affect how we think and feel. Are you having some fear about something, e.g., your health? Regular visit to your health care provider will give you assurance and expectations. You may need to take a break just to smell the flowers. Take care of yourself...
