You're lucky. The health care reform law doesn't include dental, so that must be either a state law or your mom's insurance company being generous. The company I work for is including dental coverage, but not until 1-1-11.However, as a result of law changes, I was able to go back on my mom's insurance this past year, so I have a dental plan until I turn 26 (which is in April, so I should probably take advantage of it soon).
It's my mom's insurance company. Her dental is part of her overall plan, so I get to take advantage of it for the time being. I only have a select group of dentists I am allowed to use, but it's better than nothing!
For my surgery I needed to have two canines removed, and, in order to see how well I healed, my surgeon asked my regular dentist to pull one a few weeks before my surgery. The area froze well and I didn't feel a thing, and I remember the dentist pulling at the tooth with all his might and needing the help of his colleague to pull it out. Both men almost fell backwards when the tooth finally came out, and I recall my shock at seeing how big the root was. The other canine was removed on the operating table, and I've had 30 teeth ever since.
