How Do Dental Sealants Protect Teeth?

Cavities often start in the tiny cracks and holes on the chewing surfaces of your back teeth. Even if you brush carefully, the bristles on your toothbrush are sometimes too thick to reach into these narrow spaces to remove food and germs.

This is why getting dental sealants in Calgary is such a great way to stay healthy. They act like a tiny raincoat for your teeth, stopping cavities before they even have a chance to start.

Whether you are looking for a dentist near you for your child’s new teeth or you want to protect your own smile, this simple fix can save you from needing a filling later.

How Do Dental Sealants Work?

To understand why sealants help, you have to look at your back teeth. They aren’t flat; they are full of deep valleys. These spots are like magnets for sugar and germs.

Building a Wall: The sealant is a thin, liquid coating. It is painted onto the tooth and flows into all the deep cracks.
Making it Smooth: Once the sealant fills the holes, the tooth’s surface becomes smooth. This makes it much easier to brush away germs.
Keeping Acid Out: Germs make acid that eats away at your teeth. The sealant creates a physical barrier that prevents the acid from contacting your tooth.
Stopping Germs: If a tiny bit of bacteria gets stuck under the sealant, it gets cut off from its food (sugar). This means it can’t grow or cause damage.

Are Dental Sealants Safe?

Parents often ask about the materials used in the dentist’s office. A very common question is, “Are dental sealants safe to have in the mouth for years?” The answer from health experts is a definite yes.

Very Little BPA: Some people worry about chemicals, but the amount of BPA in sealants is extremely low. You likely get more just by touching a store receipt.
No Drilling: Unlike a filling, the dentist doesn’t have to drill or remove any of your natural tooth to apply the sealant.
Keeping Teeth Natural: It is much safer for your body to have a thin sealant than to have a cavity that needs a large metal or plastic filling later.

What Happens During the Visit?

Getting sealants is fast, easy, and painless. You don’t even need a freezing shot! It usually takes just a few minutes per tooth.

Cleaning: The tooth is cleaned and dried to ensure the sealant adheres well.
Prepping: A special gel is applied to the tooth for a few seconds to roughen the surface.
Rinsing: The gel is washed off, and the tooth is dried again.
Sealing: The liquid sealant is painted onto the tooth.
Drying: The dentist uses a blue “magic light” to harden the liquid into a strong shield in about 30 seconds.

Who Should Get Sealants?

While they are very popular for kids, adults can get them too! Anyone who wants to avoid cavities can benefit from this extra layer of safety.

Kids: As soon as their adult back teeth come in (around age 6), sealants should be added to keep them safe.
Teens: When the second set of molars grows in (around age 12), those should be sealed too.
Adults: If you have deep grooves in your teeth and no fillings yet, sealants can help you keep them that way.
Prone to Cavities: If you tend to get cavities easily, sealants act like an extra insurance policy for your smile.

Taking Care of Your Sealants

Sealants are strong enough to handle chewing for a long time. However, they aren’t a “set it and forget it” fix. You still need to take care of them.

Check-ups: Your dentist will examine your sealants during your regular cleanings to ensure they aren’t chipped.
Easy Fixes: If a piece of the sealant wears down after a few years, it is very easy for the dentist to add a little more on top.
Sticky Foods: Try to avoid chewing on tough ice or super sticky candy, which could pull the sealant off.

A Complete Plan for Healthy Teeth

Sealants are amazing, but they don’t do everything. They only protect the top part of the tooth where you chew.

They don’t protect the sides where your teeth touch. This means you still have to floss every day to keep those “in-between” spots clean.

When you combine sealants with good brushing and a healthy diet, you are giving your teeth the best chance to stay strong and healthy for your whole life.
