The most important thing to understand is that you cannot leave things the way they are when you have a missing tooth.
That tooth worked in opposition to another tooth. With a hole there, the other teeth will start to shift around. This could (will most likely) over time, throw your bite of.
That in turn will create uneven wear on your teeth. That is just one small problem that can (most likely) happen.
Therefore it is important that you either get an implant or a denture. Implants can be quite expensive and dentures are not usually cheap either. Then there is the daily care involved.
You can talk over with your dentist or implantologist about what the costs and benefits / disadvantages of each are.
But do not leave a hole where a tooth used to be, this can cause many problems. It is important to get that fixed up right away.
Don't Lose Any More Teeth
The most common cause of tooth loss is gum disease. More teeth are lost to gum disease than anything else. It is tragic because many people have gum disease and have no idea that they have it. No one has really explained what is going on to them.
Dentists and hygienists probably see diseased gum tissue every day. Patients just do not fully understand what they are headed for.
Therefore, you should consider learning as much as you can about prevention and possibly stopping the progression of gum disease as soon as possible.
I guess that you would agree (I sure hope so) that you should do everything you can to save your remaining teeth.
In addition to seeing your dentist as soon as possible, here are some resources for you to learn from:
1. The Book: What You Should Know About Gum Disease
