How Long Does Dental Freezing Last?

If you’re preparing for a dental procedure, you may find yourself wondering what to expect when it comes to numbing. Will you need freezing? How long will it last? Typically, dental freezing lasts between 1 to 3 hours, but it can last up to 8 hours for more complex procedures. 

At South Bolton Dental Centre in Bolton, ON, we’re committed to ensuring you’re comfortable and informed every step of the way. Let’s take a closer look at how long dental freezing lasts, how it works, and what you can do to make the experience as smooth as possible.

How Long Does Dental Freezing Last?

The duration of dental freezing depends on several factors, including the type of anaesthetic used and the specific procedure you’re undergoing. In general, you can expect the numbness to last anywhere from 1 to 3 hours. For shorter procedures, such as fillings, the numbness might fade quickly. For more complex treatments like root canals or tooth extractions, the freezing can last up to 5–8 hours with long-lasting anaesthetics.

In rare cases, it can take until the next morning for your mouth to feel completely normal again, especially after a more invasive procedure like a wisdom tooth removal.

Why Does a Dentist Numb Your Mouth?

Numbing your mouth is an essential part of ensuring you’re comfortable during dental procedures. When the dentist needs to work in your mouth, numbing helps mask any discomfort and irritation, allowing us to perform the procedure more efficiently and safely. The freezing also helps prevent you from unintentionally moving or flinching, which could interfere with the treatment.

Dental freezing is commonly used for procedures such as:

• Fillings
• Root canals
• Tooth extractions
• Wisdom teeth removal
• Gum surgery
• Crowns
• Dental cleanings (in some cases)

Are There Different Types of Dental Freezing?

Yes, there are several types of numbing agents that your dentist may use, depending on the procedure and how long the freezing is needed to last:

• Topical anaesthetics: A gel or liquid applied to the surface area of the gums before an injection to help make the process more comfortable.
• Short-acting local anaesthetics: Used for quick procedures like fillings, these typically last 1-3 hours.
• Long-acting local anaesthetics: Ideal for more complex treatments, such as crowns, these can last 2-5 hours.
• Extra long-acting local anaesthetics: Often used for tooth extractions or other more involved treatments, they can last up to 8 hours.

Your dentist at South Bolton Dental Centre will discuss the type and duration of anaesthesia based on your procedure, medical history, and any personal preferences.

What to Expect After Dental Freezing: Tips for Recovery & Comfort

How Do You Make Dental Freezing Go Away Faster?

While there’s no way to make the numbing disappear instantly, there are a few things you can do to help the process:

• Hydrate: Drink water to help flush the anaesthetic out of your system.
• Gentle movement: Moving your mouth or chewing soft foods (once the freezing starts wearing off) can help stimulate circulation and speed up the process.
• Warm compress: Applying a warm, damp cloth to the area may help increase blood flow and ease the numbness.

Remember to avoid chewing or biting your lips, tongue, or cheeks while they’re numb, as you may unintentionally injure yourself.

Can You Eat with Dental Freezing?

It’s best to avoid eating until the numbness wears off completely. While you’re numb, you might not have full control over your mouth, which can increase the risk of accidentally biting your cheek, tongue, or lip. If you do feel the need to drink, use a straw to prevent any mishaps. Once the feeling returns, you can resume eating, but be mindful of the temperature of your food or beverages, as your mouth’s sensitivity might be temporarily affected.

What Should You Do After the Freezing Wears Off?

After your procedure, when the numbing begins to fade, you may experience some mild soreness or discomfort around the treated area. This is normal and usually resolves within a few hours. If you’re feeling discomfort in your jaw or from the injection site, an over-the-counter pain reliever (like ibuprofen) can help.

Dental Numbing Side Effects

Though dental numbing is safe, you might notice some temporary side effects. These can include a feeling of swelling, tingling, or a bitter taste in your mouth. These sensations are normal as the anaesthetic wears off. However, if you experience anything unusual—such as dizziness or a headache—be sure to contact your dentist right away.
