Gum disease is another common problem that can occur if the teeth and gums surrounding the extracted tooth are not well taken care of. And this will lead to the fact that instead of one implant, you will soon have to have several implants. Lack of teeth can also cause digestive problems. If food is not chewed properly, it causes acid reflux and a lack of nutrients that are not absorbed into the body. All of your teeth are necessary for proper chewing, no matter how useless they may seem. The possibilities of dentistry today are staggering. Every day thousands of people regain the ability to live, eat, and smile normally. It is frightening to think that just a couple of decades ago, a removable jaw was the only way to solve the problem of missing teeth.
