Dentists agree that maintaining strong teeth requires more than daily brushing, flossing, and semi-annual dental check-ups. To further reduce the risk of cavities, they often recommend preventive treatments like dental sealants. Sealants are thin protective coatings applied to the chewing surfaces of molars and premolars to prevent cavities and decay.
How Are Dental Sealants Applied?
The sealant process involves several steps to ensure a secure bond with the tooth:
First, the dentist or hygienist thoroughly cleans the tooth to remove plaque, food particles, and bacteria. Next, the surface is dried and a cotton roll or dry-angle is placed around the tooth to keep it dry. Then, a mild acidic solution is applied to roughen the tooth’s surface, helping the sealant adhere properly. After this, the tooth is rinsed and dried again.
After preparing the tooth with the steps above, the liquid sealant is brushed onto the tooth’s surface, filling in the grooves and pits. A special blue light hardens the sealant quickly. To complete the process, the dentist makes minor adjustments to ensure the sealant adequately covers the tooth, is smooth, and has not affected your natural bite.
Can Dental Sealants Trap Cavities Underneath?
Some wonder if it’s possible for a sealant to trap a cavity on the tooth’s surface under the sealant. The short answer is yes. However, if all the steps for preparing the tooth and applying the sealant are followed, this is highly unlikely.
Dentists use their expertise to assess a tooth before sealing it. If any signs of decay appear, most recommend treating it first with fluoride or a small filling before applying the sealant. Regular checkups help ensure that sealants remain intact and effective.
Is Your Sealant Still Effective?
As with most things, sealants wear down with age due to chewing and exposure to various foods. As it wears, it is important to notice the signs that indicate that a sealant needs professional attention. Here are some things to watch for:
- Rough or uneven surfaces – A well-applied sealant feels smooth, so rough spots indicate deterioration.
- Small cracks or chips – Breaks in the sealant allow bacteria to enter, so if you notice cracks or chips, get professional help.
- Food getting stuck – If food particles frequently lodge in the grooves or crevices of your tooth, the sealant is no longer doing its job and should be replaced.
- Tooth sensitivity – A previously sealed tooth that becomes sensitive to cold or sweets indicates possible decay.
Dentists check sealants during regular visits, reapplying them when necessary to maintain protection. If you have concerns about your sealants, discuss them with your dentist.

Dental sealants serve as an effective way to provide years of protection from decay. However, improper application or wear over time requires reapplication of the sealant material.
