How To Remove & Replace Dental Sealant

How To Remove & Replace Dental Sealant


Are you looking for an easy fix for your chipped, cracked, or worn-out dental sealant? Or may the sealant be replaced because it’s no longer providing the protection you need? Learn how in this comprehensive guide on removing and replacing dental sealant easily! We’ll walk you through the process step-by-step and provide some helpful tips along the way.

This guide will show you how to remove and replace dental sealant easily. Sealants are a type of preventive dental treatment that helps to protect teeth from decay. They are usually applied to the chewing surfaces of the back teeth (molars), where most cavities occur.

What is a Dental Sealant?

A dental sealant is a protective coating applied to the chewing surfaces of the back teeth. Sealants act as a barrier, protecting teeth from plaque and bacteria-damaging effects. They are most often used on molars and premolars, which have deep grooves that are difficult to clean with a toothbrush. 

Sealants are made of clear or shaded plastic and are bonded to the teeth using a special light. The process usually takes less than 30 minutes and does not require anesthesia. Sealants can last for several years but will eventually need to be replaced.

Why Do We Need To Remove and Replace Them?

Dental sealants are important for protecting your teeth against decay. However, they eventually wear out and need to be removed and replaced. Here’s why:

 Decay-Causing Bacteria: Sealants create a barrier between your tooth enamel and the bacteria that cause decay. Over time, though, these bacteria can break down the sealant.

Wear and Tear: Daily activities like eating and drinking can also wear down sealants. As they break down, they become less effective at preventing decay.

Sharp Edges: Once sealants start to wear away, they can leave behind sharp edges. These edges can catch on food and cause irritation or even pain.

How To Remove & Replace a Dental Sealant

Dental sealants are a great way to protect your teeth from cavities, but they eventually need to be replaced. Here’s a step-by-step guide on how to remove and replace a dental sealant:

  1. Using a toothbrush, gently brush the sealant off your tooth. You may need to use some floss to eliminate any tough spots.
  2. Rinse your mouth out with water.
  3. Apply a new layer of a dental sealant to your tooth using a cotton swab or other applicator.
  4. Allow the new sealant to dry for a few minutes before eating or drinking.

Materials & Tools You Will Need

To remove dental sealant, you will need the following:

  • A flathead screwdriver or another sharp, pointy object
  • Rubber gloves
  • A cup of hot water
  • Cotton swabs
  • Toothpaste (optional)

To replace dental sealant, you will need the following: 

  • Dental sealant 
  • A toothbrush 
  • Water

Get Rid Of The Old Sealant

You can skip this step if your old sealant is still in good shape. Otherwise, use a toothbrush to scrub away any old sealant around the gum line. Remove all the old sealants before proceeding to the next step.

Apply the New Sealant

If you are using a new sealant, apply it according to the instructions on the package. You must clean your teeth and dry them off before applying the sealant. Then, place the sealant on your toothbrush and apply it to your teeth. Make sure to get all of the grooves in your teeth covered. Once you are done, spit out the excess sealant.

How Long Does it Take to Set?

When it comes to dental sealants, one of the most common questions is, “how long does it take to set?” The answer is that it depends on the type of sealant material used. Some materials will set hard in just a few minutes, while others can take hours or even days to set up completely.

If you’re having your sealant applied by a dentist, they will usually use a material that sets quickly so that you can leave the office and go about your day without waiting for it to dry. However, if you are doing it yourself at home, choose a sealant that takes longer to set so that you have plenty of time to apply it evenly and avoid any mistakes.

No matter which type of sealant you choose, follow the instructions carefully so that it sets properly and lasts for as long as possible. A proper dental sealant can protect your teeth against decay for many years with proper care!


After reading through our comprehensive guide, we hope you understand how to remove and replace dental sealant better and easily. This simple step-by-step approach can help protect your teeth from future decay and save you time AND money. Regularly checking for any signs of wear or damage is key to maintaining healthy teeth and gums. If you need clarification, feel free to reach out to your dentist before making any major changes or trying anything new!


1. Is it ok to use water to remove the sealant? 

Yes, you can use water to remove and replace your dental sealant. However, we suggest using a soft brush or toothbrush so that you don’t damage the bone around your teeth.

2. How long will I eat after I get my new dental sealant? 

We recommend waiting at least 3-6 hours before eating anything exposed to food or liquids (like water). If you do not wait this long, it may cause immediate discomfort or pain due to sensitivity.

3. Can I eat after a few hours of getting my new dental sealant? 

Yes, but we recommend waiting three to six hours before eating anything exposed to food or liquids (like water).
