I absolutely agree. Her experience has been mine. First I should have acquired full dentures several years before I did. Dentists universally condemn dentures even when they are by far the most sensible option. I had the same lectures about brushing and flossing as she did. Often. Dentures take some getting used to and there is a healing process to go through but each day sees an improvement. After a few days you will be free from pain for the first time in years. Don't be frightened of having adjustments, you will need many in order for your dentures to fit properly. You no longer need to be froghtened of dental appointments as they do not hurt. You will have teeth you really like. Dentures are much better than the bad or missing teeth they replace. Dentures are a cost effective option. The greatest cost is at the beginning (mainly the cost of extractions) and after that the cost is very reasonable and dentures are easy to maintain. It is the exact opposite if you try to retain failing teeth. Eating with dentures is the biggest issue but in time you will get there and, even if there are problems along the way, eating will not cause further damage or pain.
Her bottom line: Get dentures as soon as the signs say you need them and do not delay. Ask dentures wearers rather than dentists.
