This seems to be a trend in pediatric dentistry, but I'm not comfortable with it. Anesthesia is controlled poisoning. Sounds harsh, but that's really what it is. Drugs used to sedate or put people to sleep are very powerful. Anesthesia in children is tricky because of body weight and metabolism differences, along with other variables. When my son needed a simple procedure done years ago (not dental), I took him to Children's Hospital in Phila because I knew that the anesthesia people there deal ONLY with children. I wanted their special expertise. Anesthesia is the riskiest part of any procedure, so before my little one were put under anesthesia in an outpatient setting, I'd want to know EVERYTHING, and I'd want another opinion. Ask if there are options that do not include putting your child to sleep. Ask what drugs will be used and then research those drugs. Ask who will be administering the anesthesia and who will be monitoring your child through the procedure. The dentist should not be administering anesthesia, doing dental work and monitoring your child's vital signs at the same time. That's too much for one person to do. What are the certifications and training of the person administering the anesthesia?
Children have died in dentists' chairs under general anesthesia for cavities. Whether or not it is a rare occurrence won't matter if it happens to your child. And if your child has never been under anesthesia, it's hard to gauge his reaction to the drugs. I had surgery last summer, and I had a very long meeting with the anesthesiologist beforehand to go over all sorts of health issues, allergy information, a physical exam, etc. And that was after I had already had two other surgeries under general and had no problems. I don't like the idea of just going into a dentist and sedating or doing general anesthesia on a child with no history of exposure to those types of drugs by someone who is not specifically trained to deal with children's anesthesia. Do some research before you make your final decision.
