If the dentist offers dental xrays every 6 months, is that too often?

Know why: Dental x-rays are taken to assist a dentist to reach more accurate diagnosis to treat your dental condition. A patient with high risk of decay may receive x-ray examination more often. If your dentist is concerned about rapidly receding bones or gums, s/he may order frequent x-rays. Low risk patient may receive x-rays less often. Ask your dentist to learn more about your concerning condition.

Depends on Your Risk: Dental X-rays are critical! The vast majority of dental/oral problems can ONLY be seen on X-rays, especially in adults. The frequency depends on your individual history and risk. If you have had a lot of problems and have a high risk of future problems, then 6 months sounds fine. If your overall risk is low, then perhaps 12-month intervals would be more appropriate. Your dentist can guide you.
