There are three main types of dental anesthesia: local, sedation, and general anesthesia. Local is the most common form used in dentistry, but general anesthesia may be necessary for longer, more invasive procedures that require you to be completely asleep. Local anesthetics make the mouth numb in minutes through a small gumline injection, blocking all pain signals. Sedation is used to offer a full-body calming effect during your procedure, usually administered through “laughing gas.”
Yes, the most common side effects a patient may experience are nausea, vomiting, headaches, sweating, shivering, confusion, hallucination, slurred speech, dry mouth, sore throat, dizziness, tiredness, numbness, lockjaw, and delay in the return of normal memory functioning. More major, but uncommon side effects are malignant hyperthermia, allergic reaction, nerve damage, seizure, coma, stroke, and low blood pressure. Reactions might be mild or severe and can also include rash, itching, swelling of the tongue, lips, mouth, or throat, and difficulty breathing.
