Aside from the pain due to tooth extraction or any other procedure, one more reason why sedation dentistry causes anxiety in patients is its cost. But it’s not actually that expensive. The price will depend on the drug used and your treatment in hours. The longer the procedure is, the more costly it may become.
If you have an extras policy, sedation dentistry can be covered if your policy includes dental. However, it will not cover the entire dental treatment. Note that private health funds do not pay for anaesthesia.
