To make your tooth extraction as painless as possible, your dentist may use a local anesthesia (LA). This involves a quick injection of numbing medication into your gum or cheek. To minimize potential complications, it is advisable to consume a light meal 2-3 hours prior to your appointment. This helps regulate blood sugar levels and reduces the likelihood of nausea and anxiety. An empty stomach can increase the risk of hypoglycemia, particularly for individuals with diabetes. This can manifest as dizziness, sweating, or loss of consciousness. Moreover, it can accelerate the systemic absorption of certain medications in the LA, potentially causing transient side effects.

Your dentist may ask about your recent meal. This simple question plays a vital role in ensuring a safe and comfortable dental experience. By providing accurate information, you help your dentist anticipate potential issues and provide personalized aftercare advice.

Some uncommon side effects of LA injection include;

Bruising: If the needle accidentally hits a blood vessel, it can cause a bruise to form at the injection site.

Temporary heart rate increase: A substance in the LA might temporarily speed up your heart rate.

Temporary facial numbness: The anesthetic might spread beyond the intended area, causing temporary numbness in your face and affecting your ability to smile, blink, or move your lips normally.

Nerve injury: In very rare cases, the needle might accidentally damage a nerve, leading to temporary pain or numbness.

Allergic Reaction: Modern anesthetics are less likely to cause allergic reactions compared to previously used LA.
