Injection of local anesthetic is common for most procedures: It provides patient comfort during restorative dental care.
Two or three injections are often needed with normal effects ranging from 2 – 12 hours post injection. It is okay to eat and drink, but keep in mind that sensation to biting forces and temperature is impaired. Please be careful. Almost all discomfort associated with dental procedures postoperatively is due to the injection/s and/or trauma to the gum, and not the actual procedure to the tooth itself.
Swelling, bruising and generalized discomfort at the injection site as a result of soft tissue trauma are common for up to 10 days. The discomfort may radiate and spread. Most patients feel little or no discomfort by the following day.
