Baby Tooth & Root Canal Solutions

I've had my baby tooth removed and I had a root canal on one of my front teeth. My dentist recommended I do a maryland bridge for the baby tooth and a crown veneer on the front tooth. I'm afraid that the carving on the front tooth will make it weaker. Lastly, I noticed that my dentist is general dentist and I'm unclear as to whether this qualifies him to do this work, even though he seems very knowledgeable on the process.
