If your teeth is badly decayed then it will be better to extract the teeth because it further effect rest of the teeth.
Saving Your Tooth
Without seeing an x-ray, it's hard to give you a great answer but you can always get a 2nd opinion from another dentist. A periodontist ( gum specialist) would be a good person to see for a 2nd opinion. The primary factor in the decision making is how much decay is in the tooth and how far down the tooth it goes.
