Dental Sealants Aren’t Just for Kids: Could They Help Protect Your Teeth?
Dental sealants are often associated with children getting their first permanent molars, but adults may benefit from them, too. If you have deep grooves in your back teeth or a history of cavities, sealants could offer an additional layer of protection against tooth decay.
Sealants are thin coatings applied to the chewing surfaces of molars. They help keep food particles and cavity-causing bacteria out of the small grooves that can be difficult to clean with a toothbrush.
According to the Centers for Disease Control and Prevention (CDC), dental sealants can prevent 80% of cavities in back teeth over two years. Although children and teenagers are the primary focus of sealant recommendations, certain adults may also be candidates.
At Smiles of Chevy Chase, Dr. Despina Markogiannakis can evaluate your teeth and help you understand whether sealants are appropriate for your oral health needs. Call our Chevy Chase dental office at (301) 652-2939 to schedule your appointment.
Who Can Benefit From Dental Sealants as an Adult?
Age alone doesn’t determine whether dental sealants are appropriate. Your dentist will consider the condition of your molars, your cavity history, and your overall risk of tooth decay.
Adults With Deep Grooves in Their Molars
Some molars have narrow pits and grooves that trap plaque and food debris. If these teeth are healthy and haven’t developed cavities, sealants may help protect their vulnerable chewing surfaces.
Adults Who Frequently Develop Cavities
If you’ve needed several dental fillings over the years, additional preventive care may be worth discussing. Sealants may help protect suitable molars, while fluoride treatments and changes to your oral hygiene routine can address other risk factors.
Young Adults With Vulnerable Permanent Teeth
Cavity prevention remains important after childhood. The CDC reports that adults ages 20–34 have more untreated cavities in their back teeth than any other age group. If you’re a young adult with deep molar grooves or an elevated cavity risk, ask your dentist whether sealants could help.
Older Adults Who Want to Preserve Their Natural Teeth
Older adults can develop cavities for several reasons, including dry mouth, gum recession, and exposed root surfaces. Sealants may protect suitable chewing surfaces, but they don’t address every type of decay. Your dentist can determine whether sealants or another preventive treatment would better meet your needs.
How Do Dental Sealants Protect Your Teeth?
Molars do much of the work when you chew, but their uneven surfaces can make them harder to clean thoroughly. When plaque accumulates in deep grooves, bacteria produce acids that can gradually damage enamel.
A sealant creates a protective barrier over these grooves, helping reduce the risk of decay in the treated areas. Applying one generally doesn’t require drilling or removing healthy tooth structure.
Potential benefits include:
- Additional Cavity Protection: Sealants help shield vulnerable chewing surfaces.
- Preservation of Natural Teeth: Preventing decay may reduce the need for fillings.
- A Straightforward Procedure: Application is generally quick and doesn’t require injections.
- Long-Lasting Protection: Sealants can remain effective for several years, provided they stay intact.
Sealants don’t prevent every cavity, so brushing twice daily with fluoride toothpaste, cleaning between your teeth, and attending regular dental appointments remain essential.
When Are Dental Sealants Not the Right Choice?
Sealants work best on suitable tooth surfaces that would benefit from added protection. They aren’t the right solution for every dental concern.
Your dentist may recommend another treatment if:
- A Cavity Needs a Filling: Established decay may require restorative treatment rather than a preventive coating.
- A Tooth Has a Large Restoration: Existing fillings or dental crowns can affect whether a conventional sealant is appropriate.
- Decay Affects an Exposed Root: Sealants are primarily intended for the pits and grooves of teeth, not exposed root surfaces.
- Another Preventive Treatment is More Suitable: Depending on your cavity risk, fluoride treatments or other measures may provide greater benefit.
In some cases, a dentist may recommend sealing an early area of decay that hasn’t formed a hole. This depends on the condition of the tooth and requires a professional assessment.
The goal is to choose a treatment that addresses your specific needs while preserving healthy tooth structure whenever possible.
What Happens During a Dental Sealant Appointment?
Applying dental sealants is generally a simple procedure that can often be completed during a regular dental visit.
- Examination: Your dentist checks your molars for deep grooves, signs of decay, and existing restorations. They’ll also consider your cavity history when deciding which teeth may benefit.
- Cleaning and Preparation: The selected teeth are cleaned and dried. The enamel is prepared according to the sealant material being used.
- Application: The liquid sealant is placed into the grooves of the tooth and allowed to set. Some materials are hardened with a curing light.
- Final Check: Your dentist checks the coating and makes sure your bite feels comfortable.
Most patients can return to their usual activities afterward. Your dentist will provide any specific instructions needed for your treatment.
Dental Sealants vs. Fluoride: Do Adults Need Both?
Sealants and fluoride help prevent cavities in different ways, so they can complement each other.
- Fluoride strengthens enamel and helps teeth resist acid attacks.
- Sealants create a physical barrier over the grooves of suitable molars, protecting areas where food and plaque can collect.
Depending on your cavity risk, your dentist may recommend both treatments or determine that one approach is more appropriate. You don’t necessarily need sealants simply because you use fluoride, nor should sealants replace your regular fluoride toothpaste.
A preventive plan should reflect your dental history, the condition of your teeth, and your likelihood of developing cavities.
How Long Do Dental Sealants Last?
Dental sealants can last for several years, but normal chewing forces and wear may cause them to break down over time.
Your dentist can check the coating during routine examinations and recommend repair or replacement if needed. These visits are also important because sealants don’t cover every tooth surface, meaning cavities can still develop elsewhere.
Continue practicing good oral hygiene and attending regular checkups to help protect your teeth over the long term.
