Dental implants can be used to replace missing teeth. They can also be used to replace teeth that need to be extracted. In fact, dental implants can be used to replace a single tooth, multiple teeth or even all the teeth when teeth are missing or need to be extracted.1. Replacing A Single Tooth
When a single tooth is missing or needs to be extracted, a dental implant can be placed in the jaw bone in that spot. A crown can then be attached to the dental implant to replace that single tooth.2. Replacing Multiple Teeth
You may have more than one missing tooth or more than one tooth that needs to be extracted. Many single dental implants can be placed in the jaw bone at these different positions. All of these implants can then have crowns attached to them to replace the teeth.
If you have 3 missing teeth or teeth that need to be extracted in a row, dental implants can be placed to support a bridge. One implant at each end of the long space can be used to attach a 3 tooth bridge. Several dental implant supported bridges can be used if there are several large spaces in the mouth.3. Replacing All The Teeth
If all the upper or lower teeth are missing or need to be extracted, dental implants can be used to replace all the teeth. 14 single implants and crowns can get pretty expensive and require a lot of surgery. Even several 3 tooth bridges is still a lot of money and a lot of surgery. There is an option called All on 4 where only 4 dental implants are required to hold a full arch bridge to replace all the teeth in the upper or lower parts of the mouth. For even less expense and surgery, dental implants can also be used to hold in a full denture. This is usually done if a full denture by itself is a bit loose.
