Dental sealants typically last for five to ten years, though they can stay effective for much longer with proper care. They are thin coatings applied to the chewing surfaces of back teeth to prevent decay. While they are very durable, your dentist will check them during every routine visit to ensure they are still intact and protecting your enamel.
What Are Dental Sealants?
Think of a dental sealant as a tiny raincoat for your teeth. Most cavities start in the deep grooves of your molars because food and germs get trapped there. A sealant is a plastic coating that fills those deep pits. It creates a smooth surface that is much easier to clean with a toothbrush. Since kids and teens often struggle to reach the very back of their mouths, choosing dental sealants in SW Calgary can help ensure their adult teeth stay healthy from the start.
How Long Do They Stay on Your Teeth?
Most dental sealants are designed to handle the daily pressure of chewing and biting for about a decade. However, they do not last forever. They are not like a permanent crown or a filling. Over time, the material can wear down or get chipped by hard foods. If a sealant falls off, the tooth loses its protection. This is why regular check-ups are so important for maintaining your oral health.
Why Do Sealants Sometimes Fail Early?
While many sealants reach the ten-year mark, some might only last a few years. Several factors influence how long the protective layer stays stuck to the tooth.
- Application Quality: The tooth must be completely dry when the sealant is applied. If moisture gets under the plastic, it won’t bond correctly.
- Dietary Habits: Chewing on ice, hard candies, or sticky gummies can pull the sealant away from the tooth surface.
- Grinding: People who grind their teeth at night might wear down the material much faster than others.
If you are looking for a dental clinic in SW Calgary, it is helpful to find a team that focuses on precise application techniques to make these coatings last as long as possible.
Who Should Get Dental Sealants?
Children and teenagers are the most common candidates for this treatment. This is because their permanent molars erupt between the ages of 6 and 12. Sealing these teeth as soon as they come in protects them during the years when kids are most prone to cavities.
However, adults can benefit from them too. If you have deep grooves in your teeth and no current fillings, a sealant can be a great preventive step. Finding a dental clinic near you that offers preventive care can save you from needing expensive fillings or root canals later in life.
The Application Process Simplified
Many people worry that getting sealants will hurt, but the process is actually very quick and painless. There is no drilling or numbing required.
| Step | Action | Purpose |
| Cleaning | The tooth is polished | Removes plaque and food bits |
| Drying | The tooth is kept dry | Ensures the sealant sticks well |
| Etching | A mild gel is applied | Roughens the surface slightly for a better bond |
| Bonding | The liquid plastic is painted on | Fills the deep grooves |
| Curing | A blue light is used | Hardens the material instantly |
Once the light cures the material, the tooth is ready for use. It is often a great idea to ask about dental sealants during a routine cleaning to see if you or your children are good candidates for this quick procedure.
Signs Your Sealant Needs Repair
You usually won’t be able to feel if a sealant is missing. Because they are clear or tooth-colored, they blend in perfectly. However, your tongue might feel a sharp edge if a piece chips off. At your six-month exam, the dentist uses a special tool to tug gently on the edges. If the sealant lifts, they can simply add more material to patch the gap.
Your Smile’s Long-Term Bodyguard
In the end, sealants are one of the most cost-effective ways to prevent decay. Even if they only last five years, they have protected the tooth during its most vulnerable stage. Replacing a worn sealant is much easier and cheaper than fixing a cavity that has reached the nerve of the tooth.
Keeping Your Future Bright
Taking care of your teeth is a lifetime journey that starts with simple, preventive steps. Dental sealants are a great way to add extra protection against decay, particularly amongst bigger smiles. When you have regular exams and do not munch on something extra-hard, you will be able to get these protective coatings to last for years.

Frequently Asked Questions
Can I eat right after getting sealants?
Yes, you can eat and drink immediately. Because the dentist uses a special light to harden the plastic instantly, the “raincoat” is fully set before you even leave the chair.
Do sealants feel weird in my mouth?
You might notice a slight change in your bite for the first day or two. It usually feels like a small piece of tape is on your tooth, but this feeling disappears quickly as the material settles.
Can you put a sealant over a cavity?
Usually, no. Sealants are meant to prevent decay, not fix it. If a cavity is already present, the dentist will need to remove the decay and use a filling instead to restore the tooth.
Are sealants only for kids?
While they are very popular for children, adults can get them too. As long as the tooth is healthy and does not have an existing filling, a sealant can provide excellent protection against new cavities.
