Dentists use local anesthetics while filling a tooth because they numb a specific area of the mouth rather than numbing the whole mouth. Sometimes, nitrous oxide is included to help the patient relax during the procedure. Like all serious medical procedures done with anesthesia, the patient might experience side effects. Before having any dental procedure done, it's useful for the patient to understand some of the possible effects.
Lidocaine
As with any anesthetic, lidocaine can have minor, mild or even serious side effects depending on the patient's allergies, prescription and non-presription medicine use, age and overall health. After receiving lidocaine, one might feel lightheaded, nervous, euphoric, confused, dizzy, have ringing in the ears, cold, nauseated or experience double vision. Other side effects include vomiting, sensations of heat, cold or numbness, twitching, tremors, convulsions, unconsciousness, respiratory depression and possible cardiac arrest. A slow heart rate, high blood pressure, and cardiovascular collapse could lead to cardiac arrest.
Prilocaine
Some common side effects of prilocaine include itching, nausea with or without vomiting, drowsiness, back pain and constipation. Rare conditions caused by prilocaine can be red and raised swellings on the skin, lips, tongue or in the throat, rapid heart rate, restlessness, unusual tiredness or weakness, difficulty opening the mouth, inability to control bowel movements or urine, sexual dysfunction, leg paralysis, persistent numbness and prolonged numbness or tingling in lips and mouth, shivering sensations, skin rash, tingling, bluish lips and fingernails, breathing problems, chest pain, seizures, dizziness, drowsiness, fatigue, fever, headache, irregular heartbeat, pale skin, troubled breathing, unusual bleeding or bruising, and unusual tiredness or weakness.
