Number of Roots - Front teeth cost less to treat because they have only one root, while a molar can have as many as three. More roots equal more treatment, which will result in a higher cost.
X-rays and Anesthesia - Your dentist will first need to assess your tooth with an x-ray, which carries an additional cost. Immediately before the procedure, your dentist will provide local anesthesia. If you choose to receive sedation as well, you can expect to pay more.
Follow-up Care - After the procedure, you will need to visit the dentist for follow-up appointments. You will also likely need a dental crown to repair and protect the tooth, although a dental filling may be sufficient in certain cases.
