Tooth extractions may be necessary for patients suffering from an extremely severe cavity, severe damage from oral trauma, or an infected tooth that cannot be saved with root canal therapy. In most cases, it is possible to save your tooth with a crown or root canal therapy, but sometimes an extraction may be your only option. If doctor ralston sees that your wisdom teeth are impacted or failing to erupt properly, an extraction may be recommended to ensure that your other teeth remain healthy. Not everyone needs their wisdom teeth to be removed, however. Consult with doctor ralston to find out if your wisdom teeth are or will be a problem. A tooth extraction may be required if severe periodontal disease is compromising the health of the tooth, causing it to loosen from the gums. doctor ralston may want to extract these teeth to prepare you for a strong and long-lasting tooth replacement option, such as dental implants or dentures.
