An anesthetic is needed for a dental filling to help the patient through the process. Dentists use safe, approved anesthetics to numb the area around the tooth so that the treatment is as painless and pleasant as possible. This numbness makes your lips, mouth, or cheeks feel weird.

These include your metabolism, the type of anesthetic, the dose, and how complicated the tooth filling is. For instance, having the same injection done repeatedly may make you numb for a longer time. Some patients may feel the effects for up to five hours, while others with faster metabolisms may only feel numbness for a short time. If you talk to our dentist at Dentistry on Dufferin, you can lessen the bad effects of dental fillings and get personalized advice based on your needs.
