Bye To Cavities: How Dental Sealants In Thornhill Can Help

by | Mar 31, 2023 | blog, Dental Health, Dental Services, general dentistry, Health, Preventive Dentistry, Thornhill dental services

Dental health is crucial for overall well-being, and prevention is always better than cure. One effective way to prevent tooth decay and cavities are through dental sealants in Thornhill. Dental sealants are thin plastic covering that is placed on the teeth’s surface to shield them against acid and bacterial threats. 

Who needs dental sealants in Thornhill?

Dental sealants are most commonly used on children’s permanent molars, as these teeth are the most susceptible to decay and cavities. However, adults can also benefit from dental sealants in Thornhill if they have a history of tooth decay or if their teeth have deep grooves and fissures. 

Patients with braces or other orthodontic appliances may also benefit from dental sealants, as these appliances can make brushing and flossing more difficult, increasing the risk of decay.

It’s crucial to remember that dental sealants are not a replacement for good oral hygiene habits. Regular brushing and flossing, along with routine dental check-ups, are still essential for maintaining good dental health. Nevertheless, dental sealants in Thornhill provide an extra layer of protection that can help reduce the risk of decay and cavities.


Dental sealants may be applied in a single dental appointment, and the procedure is quick and painless. 

  1. The dentist and dental team in Thornhill will clean and prepare the teeth. 
  2. They will apply an acidic solution to roughen the tooth surface. 
  3. Then, they will apply the sealant to the teeth. 
  4. Once the dentist applies the sealant, they will use a special light to harden the material, creating a durable protective layer.


Dental sealants in Thornhill offer a range of benefits, such as:

Protection against decay

Sealants form a protective barrier over the chewing surfaces of teeth, preventing food particles and bacteria from getting trapped in the grooves and crevices. This helps to reduce the risk of cavities and decay.

Easy to apply

The process of applying dental sealants is quick and painless. The Thornhill dental clinic team cleans and dries the teeth, and the sealant is painted onto the surface of the tooth. It then hardens within a few seconds, forming a protective shield.


Dental sealants in Thornhill are a cost-effective way to prevent tooth decay. They are much less expensive than fillings or other restorative procedures, and they can save you money in the long run by reducing the need for these procedures.


With the right maintenance, dental sealants in Thornhill can stay for several years. They do not require any special maintenance or treatment, and they can be easily replaced if they wear down or become damaged. Do take note that they are not to replace proper hygiene habits or bi-annual visits to the Thornhill dental clinic for cleaning and check-ups. 

Safe for children

Safe for children and teenagers, dental sealants in Thornhill are an effective way to protect their teeth during cavity-prone years. They are also a good option for adults who are at risk of developing cavities.

Type of materials used in making sealants

Dental sealants are typically made of a type of plastic called composite resin. This material is safe and durable, and it bonds well to the surface of the teeth. Composite resin is also commonly used for other dental procedures, such as fillings and bonding.

In some cases, glass ionomer cement may also be used to make dental sealants. This material contains fluoride, which can help to prevent tooth decay.

Caring for your teeth after a sealant procedure 

While dental sealants are an effective way to prevent cavities, they do require some care to maintain their effectiveness. Here are some tips on how to care for your dental sealants:

  • Practice good oral hygiene: Just because you have sealants doesn’t mean you can neglect your oral hygiene routine. Continue to brush your teeth twice a day with fluoride toothpaste, floss at least once a day, and rinse your mouth thoroughly.
  • Avoid chewing on hard objects: Although dental sealants are designed to withstand the forces of chewing, they can still become damaged if you chew on hard objects such as ice, pens, or fingernails. This can cause the sealant to crack or chip, which can compromise its effectiveness.
  • Limit sugary and acidic foods: Sugary and acidic foods can erode the protective coating of your sealants, making it easier for bacteria to penetrate the surface of your teeth. Reduce your intake of sugary and acidic foods and drinks, such as soda, candy, and citrus fruits.
  • Visit your dentist regularly: Regular dental check-ups and cleanings are important for maintaining the health of your teeth and sealants. Your dentist can monitor the condition of your sealants and identify any issues that need to be addressed.
  • Get your sealants checked regularly: Over time, your dental sealants may wear out or become damaged. It’s important to have your sealants checked regularly by your dentist to ensure they are still providing adequate protection for your teeth. Your dentist may recommend replacing the sealants if they are no longer effective.

Are you interested in dental sealants in Thornhill? 

Both composite resin and glass ionomer cement are tooth-coloured materials, which allows them to blend in with the natural colour of the teeth. This makes dental sealants a discreet and effective way to protect teeth from decay.

Dental sealants offer long-lasting protection, are painless and non-invasive, and can benefit both children and adults. If you’re interested in dental sealants or think you or your child may benefit from them, talk to a dentist at World Dental by calling now to book your next dental visit.
