My teeth are starting to gap. I have had very perfect teeth for years. No gaps or cavities. Never needed braces.

While it is commendable that the past was very healthy, this often changes as we age.  Normally, periodontal disease is the most common reason for developing gaps.  However, you mention sleep apnea.  Are you being treated?  With CPAP or an oral appliance?  Both can move teeth, especially with periodontal disease.I have had pts come in, stating they are faithful to their dentist, yet have significant periodontal disease (even to the point that some teeth needed removal).  I suggest a periodontal evaluation with a periodontist, and since you are in Frisco, go see Kent Smith for sleep information and options.

Caramelove,Thanks for your question! The truth is that teeth can move throughout life. It is called mesial drift as the teeth have a tendency to move toward the center (i.e., middle/mesial). There can be times of complete stability and increased movement. I guess, as the saying goes, the only constant is change. If you're healthy, especially as it relates to bone health, I wouldn't be terribly concerned unless there is an esthetic issue. If the food getting stuck between your teeth becomes too difficult to handle, you may want to consider orthodontic space closure to help with that.Let me know if you have any more questions.All the best,
