Sealants vs. Fillings: Prevention Is the Best Medicine
As a Southwest Portland dentist dedicated to caring for families, Dr. Kim Hoang and her team at Terwilliger Dental believes the best smiles are protected with prevention, not just treatment. That’s why we often recommend dental sealants as a simple, effective way to keep teeth strong and cavity-free.
If you’re wondering what dental sealants are, and how they differ from fillings, you’re not alone. This guide will walk you through both options as well as offer tips for how you can save time, money, and worry in the long run.
What Are Dental Sealants?
Sealants are thin, protective coatings applied to the chewing surfaces of the back teeth (molars and premolars). These areas naturally have deep grooves and pits where bacteria and food particles like to hide, making them prime spots for cavities to form.
Sealants act as a barrier, sealing off those tiny crevices so decay can’t take hold. The process is quick, painless, and non-invasive—no drilling, no needles, and no discomfort. For children and teens, who may not have perfected brushing and flossing yet, sealants are one of the best defenses against cavities. But adults with cavity-prone molars can benefit, too.
What Are Fillings?
A filling, on the other hand, is a restorative treatment used after decay has already caused damage to the tooth. When a cavity develops, your dentist removes the decayed portion of the tooth and fills the space with a durable material such as composite resin.
While fillings restore function and prevent further damage, they are a reactive treatment. That means decay has already weakened your tooth. The procedure, while common and safe, often takes more time and requires the use of dental instruments to remove the decay.
Sealants vs. Fillings: The Key Differences
Here’s a quick breakdown of the two treatments:
- Timing: Sealants are applied before a cavity develops, while fillings are placed after decay has already occurred.
- Comfort: Sealants are non-invasive and painless; fillings require drilling and numbing.
- Cost: Sealants are generally less expensive than fillings, making them a smart investment in prevention.
- Longevity: Both treatments can last for years with proper care, but sealants are a proactive measure that may prevent the need for multiple fillings down the road.
- Purpose: Sealants are designed to protect; fillings are designed to repair.
Why Prevention Matters
Think of dental care like caring for your car. Regular oil changes prevent expensive engine repairs later. Sealants work the same way—they’re a simple step that helps avoid the need for more invasive and costly treatments down the line.
As your trusted Southwest Portland dentist, we’ve seen firsthand how sealants can dramatically reduce the risk of cavities, especially in children. According to the CDC, sealants can prevent up to 80% of cavities in the back teeth for two years, where most cavities occur. That’s a powerful layer of protection for such a quick and easy procedure.
Who Should Consider Sealants?
Many patients can benefit from sealants, and most especially:
- Children and Teens: As soon as their permanent molars come in, sealants can help protect them from cavities during the cavity-prone years.
- Adults: If you’ve never had sealants and your molars have deep grooves, you may still benefit.
- Patients with a History of Cavities: If you’ve had multiple fillings in the past, sealants may help stop that cycle of decay.
The Takeaway
Sealants and fillings both have important roles in dental care but one is about prevention, and the other is about repair. At Terwilliger Dental, we encourage our patients to take advantage of preventive treatments whenever possible. Sealants are a safe, effective, and affordable way to protect teeth before cavities have a chance to start.
