I have lost 5 or maybe six teeth in the last 61 years. I figure i will be fine without them. I have brushed my teeth once a day for my entire life. Despite that calcium took out 3 of the 6 teeth. I finally had a full mouth cleaning about 3 years ago. That was so much fun. No, actually the xrays they did that lasted 90 minutes was much more exciting. Good grief.
