The removal of wisdom teeth is a common dental procedure that many people undergo, often during their late teens or early twenties. It’s a necessary procedure to ensure that the teeth don’t cause complications, such as overcrowding, infection, or misalignment. Before the surgery, there are several instructions that your dentist or oral surgeon will give you, and one of the most crucial guidelines is to avoid eating or drinking before the procedure.
While it may seem odd or inconvenient, there is a very important reason behind this rule. Understanding why you cannot eat or drink before your wisdom teeth removal can help alleviate concerns and ensure a safe and smooth surgical experience. In this article, we will explain why fasting is necessary, what happens if you don’t follow these instructions, and how to properly prepare for your surgery.
The Importance of Fasting Before Surgery
One of the primary reasons for not eating or drinking before wisdom teeth removal is to prevent complications related to anesthesia. Anesthesia, whether local or general, is commonly used during wisdom teeth extractions to ensure that the patient is comfortable and pain-free throughout the procedure. However, eating or drinking before anesthesia can lead to serious risks.
Risk of Aspiration
When you consume food or liquid before surgery, it can remain in your stomach during the procedure. If you are given general anesthesia, you will be unconscious, and the muscles that control your airway will relax. If food or liquid from your stomach moves up into the throat, it can be inhaled into the lungs. This is known as aspiration and can lead to severe complications like aspiration pneumonia.
Aspiration pneumonia is a serious infection that can result from food or liquid entering the lungs. It can cause breathing difficulties and, in extreme cases, require hospitalization. By ensuring that your stomach is empty before surgery, the risk of aspiration is minimized.
Preventing Nausea and Vomiting
In addition to the risk of aspiration, eating or drinking too close to the surgery can cause nausea and vomiting during or after the procedure. Anesthesia can sometimes make the stomach more sensitive, and when combined with food or liquid, it can lead to an upset stomach. Vomiting while under anesthesia is particularly dangerous because it can increase the risk of aspiration.
Clear Airways for Anesthesia
For both general and local anesthesia, it is crucial that the patient’s airway remains clear and unobstructed. Eating or drinking can cause stomach contents to rise up and obstruct the airway, making it more difficult for the medical team to safely administer anesthesia. This is why you are asked to avoid food or drink for several hours before the procedure.
When Should You Stop Eating and Drinking Before the Procedure?
The timing of your fasting period will depend on the type of anesthesia used and the specific instructions provided by your dentist or oral surgeon. Generally, the rule is to stop eating and drinking for at least six hours before the surgery.
General Anesthesia
If you are going to be put under general anesthesia (where you are fully asleep during the procedure), it is especially important to follow the fasting guidelines strictly. You will likely be instructed to avoid eating or drinking for six to eight hours before the surgery. This ensures that your stomach is empty and reduces the risk of aspiration and other complications.
Local Anesthesia
For wisdom teeth extractions that only require local anesthesia (where you are awake but the area is numbed), you may be allowed to drink clear liquids a few hours before the procedure, but you will still be advised not to eat solid food for at least six hours prior to the appointment. Always follow the specific instructions given by your oral surgeon or dentist to ensure the safest experience.
What Happens if You Eat or Drink Before Surgery?
While it may seem tempting to grab a bite or drink something before your wisdom teeth removal, it’s important to understand the consequences of not following your dentist’s instructions. Eating or drinking before the procedure can have several negative effects on both your safety and the success of the surgery.
Increased Risk of Complications
As mentioned earlier, one of the most significant risks of eating or drinking before surgery is aspiration. If food or liquid enters your lungs, it can lead to infection, breathing problems, and, in severe cases, life-threatening complications. Aspiration can also make the surgery more difficult, requiring extra care from your oral surgeon to ensure that your airway remains clear.
Additionally, if your stomach is not empty, the anesthetic can irritate your stomach, increasing the likelihood of nausea and vomiting during the procedure. This makes the procedure more uncomfortable and can interfere with the effectiveness of the anesthesia.
Delays in the Procedure
If you don’t follow the fasting instructions, your oral surgeon may need to delay or reschedule the procedure. The surgery cannot be safely performed if your stomach contains food or liquids. Your surgeon will need to ensure that you are in the proper condition for anesthesia, which may require fasting to be fully effective. Rescheduling a surgery can cause additional inconvenience and anxiety, so it’s crucial to follow the pre-operative guidelines carefully.
Interference with Recovery
Eating or drinking just before the procedure may also affect your recovery. If anesthesia or medications don’t work properly due to food in your stomach, you might experience more discomfort after the procedure. It may also take longer for the anesthesia to wear off, leading to a longer recovery period.
How to Prepare for Wisdom Teeth Removal Surgery
Proper preparation for wisdom teeth removal is essential for ensuring that the procedure goes smoothly and that your recovery is as quick and painless as possible. Apart from fasting before the surgery, here are some other steps you should take to prepare.
Arrange for Transportation
If you are undergoing general anesthesia, you will be unable to drive yourself home after the procedure. Make sure you arrange for someone to take you to and from your appointment. It’s also a good idea to have someone stay with you for the first 24 hours to monitor your recovery.
Follow Instructions for Medication
Your dentist may provide instructions for medication, such as pain relievers or antibiotics, to take before or after the surgery. Be sure to follow these instructions carefully, and notify your dentist if you are taking any medications, supplements, or have any allergies.
Prepare Your Recovery Area
In preparation for your recovery, make sure you have everything you need at home. This includes soft foods like mashed potatoes, yogurt, and soup, which will be easier to eat after the procedure. It’s also helpful to have ice packs ready to reduce swelling and pain relievers for post-operative discomfort.
Can You Drink Water Before the Surgery?
In most cases, you will be advised to avoid drinking anything except small sips of water on the morning of your wisdom teeth removal. Hydration is important, but excessive amounts of water can also be problematic if it increases the contents in your stomach. If your surgery is scheduled for later in the day, you may be allowed to drink water up until a few hours before the procedure. Always follow the guidelines provided by your oral surgeon.
Conclusion
While it may seem inconvenient to avoid eating or drinking before your wisdom teeth removal, this step is crucial for ensuring your safety and the success of the surgery. The risk of aspiration, nausea, vomiting, and other complications makes it important to follow the instructions carefully. By fasting for the recommended amount of time, you help ensure that your body is properly prepared for anesthesia and that the procedure goes as smoothly as possible.
Remember to follow all pre-operative guidelines provided by your oral surgeon, and don’t hesitate to contact them if you have any questions or concerns before the procedure. Proper preparation leads to a better surgical outcome and a faster recovery, allowing you to heal quickly and get back to your routine with minimal discomfort.
