Sometimes it is necessary that you need a tooth extraction for any number of reasons. Sometimes teeth can be extracted because they are very decayed, have advanced periodontal disease, or may have broken in a way that cannot be repaired from injury etc.
Other cases are that teeth may need removal because they are poorly positioned in the mouth (impacted teeth as an example), or to prepare for orthodontic treatment.
The removal of a single tooth can lead to problems related to your chewing ability, problems with your jaw joint, and shifting teeth, which can have a major impact on your dental health. To avoid these complications, we always try and discuss alternatives to extractions as well as replacement of the extracted tooth.
